Abstract

The invention discloses a configuration method for purifying river water on the basis of external circulation of combined technologies, which includes: a water storage tank is constructed beside a river channel in order to guide the water in the river channel and then guide the water to flow back to the river channel through the water storage tank, wherein the water capacity of the water storage tank is 1-10 times as the daily flow of the river channel; a plurality of biological purification units and physical/chemical purification units are arranged in the water storage tank, wherein each biological purification unit is composed of a fence, a substrate arranged at the bottom of the fence and plants planted in the substrate, and each physical/chemical purification unit is composed of a packing tank and packing, wherein through holes are formed in the side walls and the bottom of the packing tank so that river water can flow through the holes. In the technical scheme, the river water ispurified through combination of the two types of units, so that the method not only has excellent purification effect but also can remove all kinds of pollutants. The method is simple; when being stabilized, the system can work for a long time; so that the method is simple in equipment and low in cost, and is suitable for being promoted extensively.

Description

technical field [0001] The invention relates to the technical field of river water purification, in particular to a configuration method for purifying river water based on combined process external circulation. 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 peop...
