Novel air flotation turntable filtering and purifying system

Abstract

The invention relates to a novel air flotation turntable filtering and purifying system which comprises a reaction chamber, a contact chamber, a separation chamber and a filtering chamber which are connected sequentially. The reaction chamber is connected with a metering and stirring device, the contact chamber is connected with an air dissolving device, a slag scraper is arranged above the separation chamber, and a turntable filter is arranged inside the filtering chamber. The novel air flotation turntable filtering and purifying system is good in treatment effect, low in investment cost, integrative in equipment and simple in operation.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a sewage purification system. Background technique [0002] At present, among the more than 600 cities in our country, more than 400 cities have different degrees of water shortage problems. The annual water shortage reaches 60*108m3, and the economic loss caused by water shortage is nearly 300 billion yuan per year. At the same time, the current annual sewage discharge in cities in our country reaches 414*108m3. After this huge amount of sewage enters the surface water body, it will cause increasingly serious harm to the limited surface water body in my country. More than 50% of the river sections of the seven major river basins in the country There are pollution problems of different degrees. A large number of provinces and cities in Jiangsu, Shanghai, Guangdong and other places are already facing increasingly serious water pollution-based water shortage problems. Difficu...

Problems solved by technology

Although there are many reasons for this situation, the main reason is the sewage purification and reuse technology, which cannot meet the requirements of the marketization of sewage resources.

Although the traditional biological aeration technology in the past can effectively remove organic matter in sewage, its ability to remove nitrogen and phosphorus is low, and the quality of effluent water cannot meet the standard for reclaimed water reuse; although the effluent quality of membrane bioreactor technology can reach Standards for reclaimed water reuse, but high investment and operating costs limit the wide application of this technology. Other chemical and physical technologies also have problems such as high investment and operating costs, unstable effluent quality, and secondary pollution.
