Embodiment 1

[0015] A method for purifying eutrophic river water. The configuration method is to sequentially arrange a biological purification unit and a physical and chemical purification unit at the mouth of the sewage, the river water flows from the biological purification unit to the physical and chemical purification unit, and the distance between the biological purification unit and the physical and chemical purification unit is The distance to the river surface is 20mm. The biological purification unit consists of a fence, a substrate and plants. The substrate is filled at the bottom of the fence, and the plants are planted in the substrate. The plants are reeds, foxtail grass, pothos, calamus or canna. The substrate is 2 layers, and the upper layer is biological Charcoal, the particle size of biochar is 15mm, the thickness of the upper layer is 100mm, the lower layer is volcanic rock, the particle size of volcanic rock is 30mm, and the thickness of the lower layer is 150mm; There i...

Embodiment 2

[0020] A method for purifying eutrophic river water. The configuration method is to sequentially arrange a biological purification unit and a physical and chemical purification unit at the mouth of the sewage, the river water flows from the biological purification unit to the physical and chemical purification unit, and the distance between the biological purification unit and the physical and chemical purification unit is The distance from the river surface is 0mm. The biological purification unit is composed of a fence, substrate and plants. The substrate is filled at the bottom of the fence. The plants are planted in the substrate. The plants are reeds, foxtail grass, green radish, calamus or canna.

Abstract

The invention discloses an eutrophic river water purification method, and a configuration method comprises sequentially setting a biological purification unit and a physicochemical purification unit at a sewage river inlet, wherein the river water flows from the biological purification unit to the physicochemical purification unit, the biological purification unit is formed by a fence, matrix andplants, the matrix is filled in the bottom of the fence, and the plants are planted in the matrix; the physicochemical unit is composed of a filler tank and fillers, and the side wall and the bottom of the filler tank are provided with through holes for the river water to flow through. The eutrophic river water purification method adopts two kinds of unit combination processes to purify the river water, not only realizing efficient purification effect but also realizing full-scale species purification, and has the advantages of simple method, long use after the system is stable, simpledevices, low cost, and suitably 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 purifying eutrophic river water. 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 productio...
