Abstract

The invention discloses a method for purifying seriously eutrophic river water. The method mainly comprises three steps of electrolyzing, aerating and treating by a membrane bioreactor (MBR). According to the method, the pollution problems of the seriously eutrophic river can be effectively solved, the water quality of the river is improved in shorter time, so that a water ecology system is recovered, and the healthy sustainable development of a river ecology system is achieved. The invention further discloses a device for purifying the seriously eutrophic river water, which is matched with the purification method. The device comprises a dam, an electrolysis machine, an aerating device and a membrane bioreactor. According to the invention, the landscape can be combined and directly installed along the bank of the river, and the environment is hardly changed, so that the influence about the natural environment is less; in addition, the device has a simpler structure and lower production cost, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of ecological technology treatment, in particular to a purification device and a purification method capable of effectively treating river water with serious eutrophication problems. Background technique [0002] The river system is one of the important ecosystems in nature, which has multiple functions such as water delivery, flood discharge, landscape, shipping and breeding. With my country's rapid industrialization, urbanization and the intensification of non-point source pollution, river pollution has become a serious environmental problem. Excessive pollutants such as oxygen-consuming organic matter, nitrogen, phosphorus, and toxic substances enter the river water body, destroying the function of the river and the balance of water ecology, exacerbating the shortage of water resources, and threatening the health of residents near the water area. According to the recently released "2010 China Environmental Status ...
