Embodiment 1

[0015] A treatment method for polluting river water in a narrow channel, the configuration method is to set a reservoir next to the river, divert the river water in the river to the reservoir, and then divert it back into the river through the reservoir. The water capacity of the reservoir mentioned above is 1 times of the daily flow of the river water in this section. Several biological purification units and physical and chemical purification units are arranged in the reservoir. The biological purification unit is composed of fences, substrates and plants, and the substrates are filled at the bottom of the fences. , Plants are planted in the substrate, the plants are reed, foxtail grass, green radish, calamus or canna, the substrate is 2 layers, the upper layer is biochar, the particle size of biochar is 15mm, the thickness of the upper layer is 100mm, the lower layer is volcanic rock, volcanic rock The particle size is 30mm, and the thickness of the lower layer is 150mm; the...

Abstract

A treatment method for polluted river water in a narrow riverway is disclosed. The method includes arranging an impounding reservoir beside the riverway, allowing river water in the riverway to flow into the impounding reservoir, and then allowing water in the impounding reservoir to flow back to the riverway. The capacity of the impounding reservoir is 1-10 times of the daily flow of the river water. The impounding reservoir is provided with a plurality of biological purification units and physical and chemical purification units inside. The biological purification units include rails, matrixes and plants, with the matrixes being at the bottom of the rails and the plants being planted in the matrixes. The physical and chemical purification units include filler tanks and fillers. The sidewalls and the bottoms of the filler tanks are provided with through holes through which the river water flows. River water is purified by adopting a combination process of the two types of units, purification effects are good and purification materials are comprehensive in variety. The method is simple, can play a role for long time after system stabilization, and 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 a treatment method for narrow river channel polluted 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 ag...
