Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a biological nest module for slightly polluted water bodies. Background Technology
[0002] In recent years, with the rapid development of the economy and society and the sharp increase in population, a large amount of domestic sewage and industrial wastewater generated in some river basins have been discharged directly without effective treatment. In addition, non-point source pollution caused by rainwater runoff, agricultural drainage and surface runoff has been directly discharged into rivers or other water bodies. The pollution load seriously exceeds the water environment carrying capacity of the rivers themselves, resulting in serious pollution of the water environment of some rivers and their main tributaries. Pollutants such as ammonia nitrogen and total phosphorus exceed the standards seriously, the water bodies turn black and smelly, and damage the aquatic ecological environment.
[0003] Currently, the main methods for treating slightly polluted water bodies include physical, chemical, and biological methods. Among them, biological methods have advantages such as good treatment effect and low operating cost, but existing biological treatment technologies have problems such as large land area and poor treatment efficiency.
[0004] This invention fixes the biofilm carrier by placing a filling grid inside the shell, which facilitates the rapid growth of biofilm on the surface of the biofilm carrier. The biofilm on the biofilm carrier can effectively degrade pollutants such as organic matter, nitrogen, and phosphorus in slightly polluted water. Utility Model Content
