V. Preparation before the visit
Before the visit, I searched the Internet in detail for the second sewage treatment plant in Tai'an City, and actively contacted with the relevant management personnel of the sewage treatment plant, and proposed to put forward questions about the operation and management of the sewage treatment plant and process. I strive to do with the purpose, with the problem, with the task to Tai'an City, the second sewage treatment plant to carry out in-depth visits and research.
Six, visit the enterprise profile
Tai'an City, the second sewage treatment plant is the national "South-to-North Diversion of Water" supporting projects of the East Route Project, is a key project in Shandong Province, but also Tai'an City Party Committee, the municipal government around the construction of a strong economic city goals, in order to combat pollution, protect the environment, improve the quality of life of the people and the implementation of the project, and to improve the quality of life for the people. It is also a key project in Shandong Province, and a city infrastructure construction project implemented by Tai'an municipal government around the goal of building a strong economic city, in order to control pollution, protect the environment and improve the quality of life of the people.
The second sewage treatment plant project covers an area of 159 acres, the construction scale for the daily treatment of 80,000 tons of sewage, of which 20,000 tons of the depth of treatment can be reused for industrial or municipal landscape. Its annual sewage treatment 18 million tons. The project adopts oxidation ditch treatment process with the function of phosphorus and nitrogen removal, and the plant works mainly include sewage treatment works, water reuse works and ancillary buildings. The off-plant project includes 85 kilometers of supporting sewage pipe network. The project was included in the National Development and Reform Commission, "three rivers and three lakes" one of the water pollution control projects, allocated special funds to support the total project investment of 145.6 million yuan. Among them, the sewage treatment plant project investment of 93.72 million yuan, supporting the pipeline network investment of 51.88 million yuan, the project officially started in April 2003, was completed on November 27, 2005 and put into use.
Tai'an City, the second sewage treatment plant for state-owned enterprises. Registered capital of 4.32 million U.S. dollars, total assets of 9.47 million U.S. dollars, total liabilities of 5.23 million U.S. dollars; covers an area of 80 acres, construction area of 10809 square meters; the number of employees 163 people, including 62 technical managers. Main product scale: 50,000 tons of sewage treatment per day. Product quality and production technology in the domestic advanced level.
The project's financial internal rate of return (all investment) is 5.51%, which is greater than the industry benchmark rate of return of 4%, and the payback period is 14.66 years (including the construction period), which is lower than the benchmark payback period. At the same time, the construction of the project can greatly improve the quality of the urban environment and protect water bodies, with good environmental and social benefits.
The construction of the second sewage treatment plant is a major decision made by the Tai'an Municipal Party Committee and Municipal Government in accordance with the needs of urban development, in order to combat pollution, protect the environment and improve the quality of life of the people. The completion and commissioning of the second sewage treatment plant will greatly improve the urban ecological environment, and further alleviate the contradiction of insufficient water supply in the city, which will have a positive impact on the promotion of Tai'an's economic and social development.
Seven, the process of visiting
On July 30, 2018, I arrived at Tai'an Second Wastewater Treatment Plant at 8:00 a.m. on time, and contacted the management of Tai'an Second Wastewater Treatment Plant who had been contacted before, and led by them, I visited the plant in detail. During this period, the management personnel patiently explained to me the operation of the wastewater treatment plant, the main structures of the wastewater treatment plant and the process, etc., so that I understood and mastered the design characteristics of the wastewater treatment plant, the process, the design concept, the main design parameters, the selection of each structure based on the advantages and disadvantages and the operation of the existing problems and improvement measures. During the visit, I observed carefully, listened carefully, thought positively, and asked questions in time for him to help answer. The theory is linked to practice, and the benefit is great.
(a) oxidation ditch process flow diagram
Adjust the height of the overflow weir to change the depth of water in the ditch, and then change the submerged depth of the aeration device, so that the amount of oxygen adapted to the needs of operation. Changes in the submerged depth of the aeration device will also have an impact on the driving force, which can play a certain role in regulating the flow rate of incoming water; the second is through the direct adjustment of the rotational speed of the aerator: due to the development of electromechanical equipment and automation technology, the current oxidation ditch aerator speed can be adjusted to regulate the intensity of aeration of the driving force.
4, simplified pretreatment and sludge treatment
Oxidation ditch hydraulic retention time and sludge age are longer than the general biological treatment, suspended organic matter and dissolved organic matter at the same time to get a more thorough stabilization, so the oxidation ditch can be no primary sedimentation tank. Due to the oxidation ditch process sludge age, low load, the discharge of the remaining sludge has been highly stabilized, the amount of residual sludge is also less. Therefore, anaerobic digestion is no longer needed, but only thickening and dewatering.
Eight, visit experience
"Paper to get the ultimate shallow, absolutely know the matter to be practiced." Although I only had a short one-day visit to the second sewage treatment plant in Tai'an City, I learned a lot of knowledge. I am very grateful to Tai'an No.2 Wastewater Treatment Plant for giving me such a precious opportunity to visit and research. This is a wonderful chapter in our university career.
The visit and research is a comprehensive sublimation of our theoretical knowledge, is an opportunity to combine theory and practice, through this visit and research I have a deeper understanding of their theoretical knowledge, so that I feel the strengths and weaknesses of their own learning, to understand the theory and the actual production gap, and at the same time, China's modern wastewater treatment technology, monitoring technology. At the same time, I have a certain understanding of China's modern wastewater treatment technology, monitoring technology. This not only provides valuable information for my graduation, but also lays a solid foundation for my future work. The visit and research made me further understand the process of sewage treatment, so that I have a deeper understanding of the great significance of sewage treatment, and enhance the awareness of water conservation and environmental protection.
The environment is the basic premise for human survival and development, and the impact of human production and living activities on the environment is omnipresent. As a future environmental worker, I y appreciate how arduous the task I carry. This visit not only strengthened my professional knowledge, but also improved my comprehensive professional ability, independent thinking ability, practical skills, love and dedication to the quality of work, so as to be able to undertake technical work, production work and management work in the future to lay a good foundation.
In the in-depth investigation of enterprise visits, through the communication with the management of the second sewage treatment plant in Tai'an City, I realize that: our environmental engineering is a very promising profession, many enterprises need our environmental engineering professionals to manage the problem of environmental pollution. Sewage treatment plant is our environmental engineering
Specialized graduates of a very good place of employment. Tai'an No.2 Wastewater Treatment Plant welcomes our graduates from Qingdao Agricultural University to work in its plant. At the same time, he also put forward some comments and suggestions on our school's curriculum system, such as: encourage students to actively visit and practice in enterprises related to their own specialties, etc.; require students to build a solid theoretical foundation; cultivate students' spirit of hard work and endurance, and so on. At the end of the visit, I warmly invited Tai'an City, the second sewage treatment plant to our Qingdao Agricultural University for preaching and recruitment, etc., the plant said very happy to accept our school graduates.
"Hardship knows life, practice grows talent". In the in-depth enterprise visits and research, I learned how to communicate effectively with people, how to put the theoretical knowledge learned into practice, how to analyze and solve problems. At the same time, I understood the society, broadened my horizons, grew my talents, and recognized my own position, found my own shortcomings, and was able to make an objective evaluation of my own value. This inadvertently make me have a correct positioning of themselves, enhance my confidence and perseverance to study hard. I will work harder to learn scientific and cultural knowledge, and become a pillar of the country as soon as possible, to return to society.

Part 3
The Legal Affairs Office to the Yunnan-Guizhou four companies in the enterprise legal system work research and on-site legal service activities carried out since the Director of the Office of Hong Xiaoshan, Legal Affairs Office, visited the development of resources in Qianxi South China Development Company Limited (Anlong Company), Yunnan Zhuangxiang Cement Co. Ltd., Wenshan Conch Cement Co., Ltd. and other four enterprises, through the field view, to carry out seminars and other forms of serious understanding of the current situation of business operations and the existence of difficulties, combined with their own work put forward a lot of solutions to the problem of countermeasures and methods, and the formation of a written report of the study.
In the afternoon of August 14th, Director Hong went to Anlong to carry out research, through visits, talks, on-site on the actual problems encountered in the daily operation of the enterprise to answer, is now the talks of the issues raised by the comb as follows: First, the quality control of cement, the company's quality of the relevant management personnel reflected the company's quality department, the enterprise through the issuance of the cement manual to the customer, will it be The customers will not recognize Conch's cement quality requirements, which will lead to the legal risk of quality complaints. Secondly, in the management of contract signing, the contract management personnel of the company reflected that in the process of contract bidding, it is necessary to determine the winning unit by the total contract price, but according to the company's system, it may be involved in the determination of each sub-item under each contract, which is not only very difficult to operate, but also easy to generate contract risks. Third, corporate sales management, the company's sales office staff reflected that the company's sales have no regional price, no transportation bidding, pickup vehicles are dealers to arrange, in accordance with the standard text of the contract provided by the Ministry of Sales signed, there is no great dispute over the issue, but the follow-up need to continue to improve the contract text, through
By signing a supplementary contract in the form of the content of the contract, delineate the responsibility to avoid unnecessary legal risks.
Fourth, the enterprise safety production, production safety office personnel reflected that the enterprise environmental protection acceptance, safety acceptance has not yet passed, health occupational health license, safety production license has not yet been processed for the trial production license, but it is already the third time to extend the expiration at the end of August 2014, and apply for another extension will not be approved. In addition, the mining right certificate and safety license of the mine are available, and there is no transboundary mining, but the forest land certificate of the mine has not been processed. Fifth, the implementation of the big agreement, the company's land immediately carry out land audit, land land use indicators have been reported, but need to pay money, the government is currently talking about no money, the need to borrow money from the enterprise, this piece of more trouble.
Sixth, the implementation of procurement contracts, the company's financial staff reflected, in the local procurement of materials, often encountered suppliers casually fraudulent use of other people's qualifications, change the scope of business, although the local industrial and commercial bureaus to be changed, but there is still a risk of violating the law.
Seventh, sales invoicing, if the ordinary customers to the company account, we issued invoices, the customer to take the VAT invoice offset, so that there is no legal risk of operation, the key customers to open an account, there is no reason for the company not to open, but this will involve the risk of false VAT invoices. Eighth, the equipment sales contract, the company has part of the equipment sales contract expires, the supplier arrived late, can cancel the contract and deduct liquidated damages, at the same time, because the equipment contract mainly rely on the ministry contract text signed, the company itself on the contract text modification can not be specifically operated on the performance of the contract there are greater constraints.
Ninth, labor and personnel, the company's office staff reflected that some employees leave the office without saying hello, the company in accordance with the employee's labor contract left the address of the separation formalities to send out the materials, but sometimes encountered by the post office to return the case, so how to avoid a risk. Tenth, the supply of security, in accordance with the company's system and the surrounding suppliers to discuss the formation of the negotiation record, the requirements of the supplier must first pay the deposit and then supply, but due to the lack of cooperation of the supplier, we take in the first batch of payments deducted from the corresponding deposit, so that the operation of the company's financial requirements are inconsistent with the existence of legal risks.
Eleventh, on the quality of objections to processing, the company in the contract performance for the supplier to supply the quality of objections, text messages, written faxes requesting the other seal feedback, the other side is often a long time to delay, there will be legal risks. Twelfth, on the signing of the contract quantity terms, such as auxiliary materials contract, the contract predicts the purchase of a larger amount, but the actual number of possible purchases is relatively small, although the contract is written in the tentative number, the specific to the actual number of prevail, so there is no risk?
The afternoon of August 15, to Zhuangxiang company to carry out research, it is understood that the company belongs to the acquisition of the project, production capacity is relatively small, but because it is located in the second largest town in Yunnan Province, Babao Town, is located in the junction of Yunnan, Guangxi, Guizhou Province, the pressure of external competition relative to other regions is relatively small, since November 2013, the profit has been more than 15 million yuan, due to the company's Since its predecessor was acquired by Conch one year after it was put into operation, the fulfillment of the equity acquisition agreement has been relatively smooth, and no difficult-to-handle legacy problems have been found. At present, the company's production and operation rights are complete, and the main problem is that it is difficult to communicate and coordinate with the local government departments, and it is difficult to deal with the local banks, which to a certain extent restricts the development of the work.
In the afternoon of August 16th, we went to Wenshan Conch Company to carry out research, and through the visit and on-site inspection, we learned that Wenshan Conch Company is one of the key construction projects in Wenshan Prefecture, which is in line with the requirements of the national industrial policy. The company is located next to National Highway 324 in Asanlong Village, Pingyuan Town, Yanshan County, Wenshan Prefecture, Yunnan Province, 220 kilometers away from Kunming. The company was formally registered and established on April 9, 2018, with a planned investment of RMB 1.8 billion. The project plans to build two new dry-process clinker production lines with a daily output of 4,500 tons, a cement grinding system with an annual output of 2.2 million tons, and is equipped with a 9MW low-temperature waste heat power generation system, which will be able to produce 3 million tons of high-quality clinker and 4.5 million tons of high-quality cement annually upon completion.
On the morning of August 18, 2014, to Kunming Hongxi company to carry out research, through visits, talks, on-site on the actual problems encountered in the day-to-day operation of the enterprise to answer, is now the discussion of the issues raised by the comb is as follows: First, on the cancellation of the mine sales contract, the original contract is not operational, the other party has invested in the handover of the former has invested in a larger facility and put forward a claim. There is a contract dispute, the need to immediately terminate the contract, what are the legal risks. Second, limestone mine mining, transportation outsourcing contract, the transferor in the management of the right to hand over six months after the transition period to complete the contract cancellation procedures, the original company's limestone mine mining, transportation outsourcing is a contract with two natural persons, there is a greater risk of security.
Third, the company set up on June 10, the arrears clearance team, to July 10 has been and arrears of units all check clearly, all obtain a written statement of account, has recovered accounts 440,000 yuan, but as of August 6 to undertake the list of claims payment is still 18,447,300 yuan has not been recovered in a timely manner, the need to be how to avoid the risk of uncollectible accounts receivable.
Fourth, the company has seven employees and the original company labor contract has not been terminated, and with the new company did not sign a labor contract, now requires the company to coordinate the termination of the labor contract and economic compensation, the company is equal to the current holiday to them, the specifics of how it should be operated; and another part of the people do not come to work to take the initiative to resign, but the old shareholders side does not agree with their resignation, can direct access to the Labor contract.
Fifth, the company's mine land acquisition compensation, compensation for nearby road land acquisition and compensation for environmental pollution.
Sixth, Kunming Hongxi company external power supply lines by the China Southern Power Grid Company Shilin Power Supply Co., Ltd. power supply, the line from the Shilin substation cement line to the company's total drop total length of 1.8 kilometers, to join the conch before the existence of internal external power supply, in accordance with the Southern Power Grid management system, belongs to the power supply violations, how to avoid the risk.
Seventh, the supply department related personnel reflected, in the new and old shareholders during the handover of a batch of coal, the original shareholders signed the price is relatively high, the quality of the assessment of the provisions basically do not have, conch took over the acceptance of the quality of the unqualified, asked for the return of the other party has not been to assist in resolving, if the direct deduction of the coal payment, whether there is a legal risk.
Eighth, cement quality control, the company's relevant managers reflect the company's quality disputes small disputes are more, has not yet produced a large litigation disputes, on the emergence of the problem should be how to operate in order to avoid legal risks.
Ninth, the company used to take the cement to offset the payment of coal and other materials, there are financial personnel commissioned by the coal boss to sell part of the cement, there are not commissioned to sell part of the cement situation, the company's financial staff of this behavior in the end is on behalf of the company's behavior or personal behavior, which will produce what legal risks.
