Wastewater treatment plant is the use of biochemical treatment of wastewater, so the biochemical wastewater in the ammonia nitrogen still does not meet the standard may be due to:
1: sludge sludge is older, and some of the sludge is already aging
2: the temperature of the water body is low, the bacterial strain of the activity will be low
3: not enough aeration in the water body, oxygen content Not high
Question 2: What is the reason for the excessive ammonia nitrogen in domestic sewage? How to deal with it? Vito environment 100,000 volts team for you to answer.
1, the reasons for exceeding the standard may be:
1) your company is more economical water;
2) your company is very dense, many people, the toilet is used frequently;
3) your company's personnel defecation time period is more concentrated, such as focusing on the daytime, the sewage plant sampling is also in the time period.
4) The discharge port is very close to the toilet (resulting in the samples taken by the sewage plant personnel are not representative).
5) Other sewage was mixed in.
2, the investigation method: regular sampling and testing;
1) in the same day at different times in the discharge port were sampled, measured ammonia nitrogen value.
2) Take samples from different discharge wellheads in the plant to determine the ammonia nitrogen value.
3) Determine the ammonia nitrogen value of the sample in the nearest pipe inspection well near the toilet.
Analyze them separately to determine if your facility is discharging unevenly, if the sampling is unrepresentative, and if the toilet discharge water is the cause.
If none of these are true, then there is bound to be a well with a high ammonia nitrogen value somewhere, and investigating the source of the wastewater there will determine where the high ammonia nitrogen value wastewater comes from.
3, treatment: do not know the reason, there is no specific improvement method. In short, the right medicine can be.
4, the purchase of tools and facilities: If your unit of ammonia nitrogen value exceeds the standard a lot, and ultimately found that there is no objective reason, is to exceed the standard, then you need to set up treatment facilities.
Problem three: how to deal with high ammonia nitrogen in urban wastewater treatment plant high ammonia nitrogen in urban wastewater treatment plant water, simple and the fastest and most stable solution is to install a microbial generator, microbial generator the main advantages are as follows:
1, a high degree of automation, wastewater treatment effect

2, a wide range of adaptability
The equipment for the more ideal sewage biological purification and treatment equipment, according to different kinds of sewage treatment needs, different nature, different environments, to generate different populations, different genera, different temperatures, different sewage treatment of micro-organisms, especially suitable for urban sewage, rural sewage, sewage, medical wastewater, industrial wastewater, livestock and poultry waste water, high salt wastewater, high temperature, high wastewater, high quality wastewater, high quality wastewater, high quality wastewater, high quality wastewater. It is especially suitable for urban sewage, rural sewage, medical sewage, industrial wastewater, livestock and poultry wastewater, high salt wastewater, high ammonia wastewater, toxic wastewater, heavy metal wastewater, garbage leachate and other wastewater (sewage) treatment needs.
The equipment can also be directly with the contact oxidation method, AB method, A/O method, oxidation ditch, SBR and other old wastewater treatment projects, in neither change the wastewater treatment process, nor change the conditions of civil engineering, to achieve the upgrading and expansion of wastewater treatment, sludge reduction, denitrification and dephosphorization, reuse of water and other purposes. The equipment can also be used in landscape, river, lake, river, saltwater lake, bay, land and other fields to remove micro-pollution and protect the public **** environment.
3, outstanding economic benefits
The micro-device produces high-density advantageous microbial flora, can quickly eat off the pollutants and sludge in the sewage, and does not produce odor, without sludge dewatering machine, sludge conveyor, mud cake outgoing car, exhaust gas treatment equipment and high-power blower aeration equipment, and the traditional method of comparison, the energy consumption of the activated sludge method is 1/8, the investment of the equipment can save Seventy percent, but also in the shallow pool on the operation, so that the sewage treatment tank volume shrinkage, shallow depth, greatly reducing the cost of a one-time investment and long-term management costs.
4, easy to manage, safe and reliable
The equipment produces a high density of microbial flora through the jet stream into the treatment pool, can quickly reduce the biological oxygen consumption in sewage (BOD), chemical oxygen demand (COD) and solid suspended solids (TSS), and has a strong function of denitrogenation and removal of phosphorus, but also in a very short period of time to make the 5 types of water into more than 3 categories, 7 days to eliminate The odor in the sewage, eat about 50% of the sludge in the sewage in 10 days, degrade 20% of the BOD every day, and achieve standard discharge or water reuse in 10-15 days.
Using this equipment to treat sewage without the worry of sludge expansion, but also not subject to the age limit of the operator's education, easy to manage, safe and reliable.
5, no secondary pollution, creating a green environment
With the increasing incidence of high-density microbial flora, biological oxygen consumption (BOD) in the sewage is less and less, a large number of microorganisms due to the lack of BOD and the loss of energy to survive self-extinguishing into carbon dioxide and water, the micro-organisms not self-extinguishing can also become the bait of the fish and zooplankton, and then the formation of benign ecological
The treatment and purification process, there is no odor, no smell, and no water, the water can be used to treat the sewage. Processing purification process, no odor, no sludge, no secondary pollution, creating a green environment.
6, not affected by the climate, complete biochemical treatment
The use of traditional biochemical method of sewage treatment, affected by the climate and water temperature changes, when the temperature is reduced by 10 degrees per microbial enzyme reaction rate is reduced by 1-2 times, the climate leads to microbial activity is insufficient, resulting in a bad effect of sewage treatment, not only threatened by the northern sewage treatment plants, for the southern winter sewage treatment plant is also a severe test of the Treatment plant is also a severe Jun test, Guizhou Great Wall Environmental Protection Science and Technology Co., Ltd. production of patented products microbial purification and treatment equipment completely solved this problem, the generator system produces a high concentration of microbial flora released into the microbial purification and treatment system, its biomass interrogation rate of more than 2.0 × 104mg/L, so that the microbial purification and treatment equipment in the biological concentration of activated sludge compared to improve 10 times. It fills the technical problem of insufficient biomass and poor sewage treatment effect due to low water temperature.
7, to solve the lack of activity, to ensure that the water quality standards
The traditional biochemical treatment of high concentration, high ammonia nitrogen, high salt, toxicity, heavy metal wastewater, due to the microbes in the sewage in the small number of live, small, resulting in sewage treatment of the effluent water quality is poor, the effect is unstable, and difficult to meet the standards of discharge. Microbial purification and treatment equipment in a unique way to completely solve this problem, the microbial generation system can produce more than 1.8 × 1020CFU/ml ...... >>
Question 4: the exceedance of ammonia nitrogen in the domestic wastewater treatment plant, what is the main reason for the existence of N-containing organic matter in the domestic wastewater, after the microbial biochemical effect of ammonia nitrogen accumulation caused by the exceedance of the standard, more common!
Question 5: Please teach the reasons for the exceedance of ammonia nitrogen in domestic sewage from the daily chemical products we use.
Question 6: What causes high ammonia nitrogen Ammonia nitrogen (NH3-N) mainly comes from bait (feed), aquatic animal excreta, fertilizers and decomposition of animal carcasses. Ammonia nitrogen is the main waste nitrogen in the water body, in the pool water pH is high, ammonia nitrogen can return to the atmosphere, or in the form of nitrogen back to the atmosphere, but also partially consumed by aquatic plants, partially adsorbed by the substrate. Ammonia nitrogen is usually produced as a result of the decomposition of nitrogenous organic matter in times of insufficient oxygen, or as a result of the reduction of nitrogen compounds by denitrifying bacteria.
Question 7: What happened to the excess total nitrogen in the effluent from the wastewater treatment plant? It is recommended to check whether the nutrient balance (BOD5: N: P = 100: 5: 1) is normal, as well as the nitrification process, whether the alkalinity is sufficient, which directly affects the nitrogen removal efficiency. There are also traditional oxidation ditch denitrification, mainly using the uneven distribution of dissolved oxygen in the ditch, through a reasonable design, so that the ditch produces alternating cycles of aerobic and anoxic areas, so as to achieve the purpose of nitrogen removal. Its biggest advantage is to realize the removal of organic matter and total nitrogen in the same ditch without additional carbon source, so it is very economical. However, it is difficult to accurately control the volume and dissolved oxygen concentration of each of the aerobic and anoxic zones in the same ditch, so the effect on nitrogen removal is limited. On the issue of water treatment, you can go to the environmental protection pass question, where the interaction of more people
Remember to adopt ah
Question 8: sewage plant ammonia nitrogen exceeded the reasons, tail gas exceeded the standard 30 times what reason, sewage ammonia nitrogen exceeded the standard may be the following conditions:
1, is the nitrification reaction out of the problem, look at aeration pool of a variety of parameters is normal.
2, after hydrolysis acidification, organic nitrogen ammonia, ammonia nitrogen concentration increases, the aeration pool nitrification is limited.
Solution: add a nitrification and denitrification reactor as an emergency facility to be put into use when ammonia nitrogen is high.
Question 9: What are the main reasons for sewage export ammonia nitrogen exceeded? Ammonia nitrogen exceeds the standard and did not discharge mud has nothing to do with, on the contrary, nitrifying bacteria need a longer sludge age, on the contrary, can not be overly diligent sludge discharge.
See if the influent ammonia nitrogen is high or organic nitrogen is high; whether the aeration is not enough or the residence time is too short; whether the age of the sludge is too short, resulting in the loss of nitrifying bacteria; whether there is poisonous inhibition and so on
You said too Gong single, can not be judged in detail, they can be judged according to the actual situation
Problem 10: sewage ammonia nitrogen exceeded the standard treatment, how to calculate the ratio of Out of the ammonia nitrogen has reductive, too much in the water body will lead to a reduction in the oxygen content of the water, algae growth, and even the death of fish and shrimp serious consequences. Taihu Lake basin, Yunnan Dianchi and other famous waters on many occasions in the case of cyanobacterial bloom, the main reason is also because the water is too much reducing substances, consuming the oxygen in the water.
Ammonia nitrogen in sewage exceeds the standard, the most effective method is microbial treatment, through the decomposition of multiple groups of anaerobic and aerobic organisms, you can make its content a large number of reduced. Of course, you can also use the traditional method of nitrification, but also can make its content greatly reduced.
At present, the standard unit of ammonia nitrogen water treatment: ppm (mg / L), the standard is not the same everywhere, you can use distillation, heating colorimetry and other methods of detection.
