Abstract

An efficient purification method for eutrophicated wastewater is disclosed. The method includes arranging a biological purification unit and a physical and chemical purification unit in order at a river mouth from which wastewater enters a river. The river water flows from the biological purification unit to the physical and chemical purification unit. The biological purification unit includes a rail, a matrix and plants, with the matrix being at the bottom of the rail and the plants being planted in the matrix. The physical and chemical purification unit includes a filler tank and a filler. The side wall and the bottom of the filler tank are provided with through holes through which the river water flows. The river water is purified by adopting a combination of the two units, purificationeffects are good and purification materials are comprehensive. The method is simple, the system can play a role for long time after stabilization, and the method is simple in equipment, low in cost and suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of river water purification, in particular to an efficient purification method for eutrophic sewage. Background technique [0002] With the rapid development of society and economy, the population has grown rapidly, the discharge of pollutants has increased significantly, environmental protection has lagged behind, and the level of governance has not kept up with the high economic development, resulting in a large number of pollutants entering the water body with sewage, garbage, precipitation and runoff, resulting in The quality of the environment has deteriorated. Eutrophication of water body is one of the important signs of extreme deterioration of water quality, and it is also a serious problem in water pollution in the world today. With the development of industry and agriculture, more and more organic pollutants such as nitrogen and phosphorus produced in people's life and industrial and agricultural ...
