Description
Technical Field
The invention belongs to the technical field related to water purification, and particularly relates to a hydraulic spinning biological membrane purification system for micro water and a working method.
Background
Due to excessive fertilization and industrial production activities, a large amount of nitrogen-containing compounds enter small micro water bodies such as rivers and lakes with poor self-cleaning capability, however, when the content of ammonia nitrogen in the small micro water bodies is too high, a series of serious environmental problems such as water eutrophication and aquatic organism diversity reduction can be caused, and finally, the influence on the life health and safety of human beings is caused. At present, ammonia nitrogen becomes a parameter index which is the first investigation in water pollution in China. According to the survey in recent years, the occurrence frequency of ammonia nitrogen in over-standard pollutants in surface water bodies in China is very high and tends to be increased year by year, for example, the ammonia nitrogen content of other water systems except for Zhujiang river and Changjiang river in seven water systems exceeds the ammonia nitrogen limit value (0.5 mg/L) in sanitary Standard for Drinking Water (GB 5749-2006), and in addition, the ammonia nitrogen content in a plurality of local water systems in China is more than 4mg/L, and some ammonia nitrogen contents even reach 50.4mg/L at most. Therefore, the solution of the ammonia nitrogen pollution problem in surface water becomes an important content in the water treatment field in China.
The pollution treatment technology available at present for small and micro water bodies with over-high nitrogen content mainly comprises a physical method, a chemical method and a biological method. The heterotrophic nitrification-aerobic denitrification process by biological method is the most reasonable in the technologies from the viewpoint of thoroughly eliminating nitrogen pollution and reducing economic cost. The process can use organic carbon as an electron donor, and can generate higher nitrification and denitrification rates. However, the lack of available carbon sources is a worldwide problem in the heterotrophic nitrification-aerobic denitrification process for small micro-water bodies with low carbon-nitrogen ratio. At present, researches on carbon sources adopted by a heterotrophic nitrification aerobic denitrification process mainly focus on the aspects of deep development and utilization of system carbon sources and accurate addition control of traditional external carbon sources, and few researches on the characteristics of promoting nitrification and denitrification by using a novel slow-release carbon source and engineering applications are carried out. In addition, the water body is usually purified by adding a slow-release carbon source, so that the polluted water bodies such as rivers, lakes and the like are easy to run off, the contact area time is short, and the purification effect is poor. The slow-release carbon source is used as a material to serve as a filler, so that the slow-release carbon source not only can be used as a carrier for the growth of a biological film to promote the biological removal of pollutants, but also can be used for slowly releasing carbon to provide a carbon source for a water body with a low carbon-nitrogen ratio, and the removal rate of nitrogen in the water body is improved. Based on the background, the invention provides a biofilm filler hydraulic self-rotating device with a carbon source slow release function, and the purification and the improvement of the water quality of micro water bodies are realized.
