Abstract

The invention discloses a method for efficiently purifying polluted river water through a combined process. According to the collocation method, a biological purifying unit and a physical chemistry purifying unit are arranged at a sewage entering mouth in sequence, the river water flows from the biological purifying unit to the physical chemistry purifying unit, the biological purifying unit is composed of a fence, matrix and plants, the bottom of the fence is filled with the matrix, and the plants are planted in the matrix; the physical chemistry purifying unit is composed of a filler tank and filler, wherein through holes for the river water to flow through are formed in the side walls and the bottom of the filler tank respectively. The method for efficiently purifying the polluted riverwater through the combined process is characterized in that the two-unit combined process is adopted for purifying the river water, not only is the purifying effect high, but also purifying species are comprehensive, the method is simple, a system can come into play for a long time after being stable, equipment is simple, the cost is low, and the method is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of river water purification, in particular to a method for efficiently purifying polluted river water with a combined process. 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 in...
