Question 1: How to deal with construction waste in Hangzhou. Construction waste treatment method:
The comprehensive treatment method of construction waste first uses the construction waste generated from the demolition of buildings, house decoration and road reconstruction. The vehicles are transported to the processing site, and then the directly recyclable materials in the construction waste, such as metal materials, wooden materials and plastic materials, are manually sorted and classified, and directly supplied to the corresponding company for processing. Use a large hammer or crusher to crush the large pieces of waste concrete, waste bricks, marble and other materials in the construction waste to the size that the crusher can crush, generally less than 100 mm, and then use a stone crusher to crush them to the building site. The required gravel and sand are then classified into coarse gravel, fine gravel, coarse sand, fine sand, mud sand and other recycled materials that meet building standards through a multi-layer grading screen. The production water uses activated carbon reverse osmosis to purify domestic sewage and recycle it, which can not only save water but also prevent the re-discharge of sewage from polluting the environment. If it's too troublesome, you can take him to the construction waste disposal site yourself, but ordinary cities may not have such facilities.
Question 2: How much does it cost to clean up construction waste in Hangzhou? If you decorate your house yourself, you should have no problem cleaning it up yourself. Nowadays, many people hire a decoration team to transport it away. Most of them charge 20-50 yuan/o, depending on what type of garbage you are.
Question 3: Where to throw construction waste in Hangzhou? (Urgent) (High score) I’ll give you an official solution
The contact number of the city’s solid waste direct transportation company is 88123111 (8:00-16:00)
I was caught in the act. The payment is upwards of 1,000
Question 4: Where is the construction waste around me in Hangzhou City? Houses are being demolished, a lot of garbage
Here in Dingqiao Town, Jianggan District, Hangzhou City< /p>
Question 5: How is the construction waste of Qiaosi, Yuhang, Hangzhou handled? Is that a garbage incineration plant? Construction waste is not accepted, and general landfills do not receive construction waste in large quantities. They usually have special disposal sites. If you look at a construction site that is being excavated, there will be so much dirt that there is no place to dump it.
Question 6: How much is the cost of building demolition, garbage removal and truck loading in Hangzhou? The freight is 100 yuan for 50 kilometers. The cost of demolishing a brick wall is RMB 10 per square meter, a concrete wall is RMB 22 per square meter, and a reinforced concrete wall is RMB 30 per square meter
Question 7: What are the current general garbage disposal methods and what are the current general domestic garbage disposal methods? Methods include:
1. Landfill. This is the most commonly used treatment method and is also the cheapest.
2. Burn. Crush domestic waste and burn it, or burn it to generate electricity. Some waste can be burned in cement kilns.
3. Recycling. Recycle recyclable plastics, metals, etc.
4. Compost. Crush waste with a lot of organic matter for composting or fermentation.
The following is for reference only:
1. Basic Current Situation China's garbage treatment started late, and its ability to harmlessly treat garbage is low. There was a serious situation where garbage surrounded the city. In recent years, China's environmental sanitation industry has made great progress, which has improved the level of urban garbage disposal and alleviated the phenomenon of garbage surrounding cities. According to statistics in 1994, there are about 380,000 sanitation employees in cities across the country, and about 34,400 various sanitation machinery. The garbage treatment rate reaches 35.8%. 609 harmless treatment sites have been built. The harmless treatment capacity of garbage and processing rates have grown significantly in recent years. Major cities in China have established environmental sanitation research institutions and carried out research on urban waste treatment technology and equipment. During the "Eighth Five-Year Plan" period, the state allocated nearly 10 million yuan and loaned tens of millions of yuan to carry out scientific research, development and demonstration projects for urban waste composting, landfill, incineration and resource utilization. 2. Application of garbage treatment technology The management of urban garbage is a systematic project, including garbage collection, transportation, transfer, processing and resource utilization. 1. Collection of urban garbage Most cities and towns in China currently use mixed collection methods for garbage collection (except hospital garbage).
The garbage operation methods and equipment used mainly include the following: fixed garbage bins, garbage storage and collection, movable garbage bins, garbage collection, trash can collection, and plastic bag collection. Sealed container collection and ground garbage station collection, etc., most cities can achieve timely garbage collection and keep the environment in residential areas clean. 2. From an overall perspective on urban garbage transportation, the mechanized collection and transportation rate of urban garbage in China is low. The labor intensity of sanitation workers is high, manual operations are insufficient, and the equipment performance is poor. About 40% of the sanitation equipment and vehicles in the country need to be updated, and about 10% of the sanitation equipment and vehicles need to be updated every year. As a result, 10 million tons of urban garbage cannot be transported to treatment sites in time. 3. The current garbage treatment sites and resource utilization technologies used in urban waste treatment in China are the same as those in other countries in the world. They mainly use methods such as sanitary landfill, composting, and incineration. Most of the urban waste is processed by stacking, simple landfill, sanitary landfill, and mechanization. Composting and incineration are also partially used. China's urban domestic waste treatment methods mainly include waste-based building materials (bricks) and comprehensive utilization. (1) Application of landfill technology For a long time, most cities in China have adopted methods such as open-air stacking, natural ditch filling, and pit filling. Only general anaerobic treatment can be achieved. However, in recent years, the construction of landfills has become increasingly perfect, and a number of higher-level landfills have been built one after another. Cities such as Hangzhou, Guangzhou, Suzhou, Beijing, Chengdu, and Baotou have established relatively complete landfills based on the actual conditions of the city. of sanitary landfills. At the same time, the technology for recycling and utilizing biogas produced in landfills has also been developed. At present, landfill is still the most important method of harmless treatment of urban landfill waste in China. (2) Application of composting technology In recent years, China's garbage composting has developed rapidly. The "secondary fermentation process" has been applied since the 1980s. Due to the adoption of forced sealing and aerobic fermentation, the fermentation cycle has been shortened. The composting machinery has become increasingly perfect, and production has tended to be industrialized. At present, cities such as Wuxi, Changzhou, Tianjin, Shenyang, Beijing, and Wuhan have designed their own mechanized garbage composting production lines suitable for China, and many cities also have a considerable number of simple garbage composting plants. (3) Application of incineration treatment technology Research on waste incineration technology in China started in the mid-1980s. Incineration technology is the most effective way to harmless, reduce and recycle waste, and is the future development method of waste treatment. Currently, China Only a few cities such as Shenzhen, Leshan, and Xuzhou have established waste incineration treatment plants and conducted demonstration tests of incineration power generation. The system is operating well, but the scale is small and the daily processing capacity is low. Large and medium-sized cities such as Beijing, Shenyang, Shanghai, Beihai, and Guangzhou are currently planning to build larger-scale waste incineration sites.
