In-situ treatment method for improving quality of surface water environment

Abstract

The invention discloses an in-situ treatment method for improving the quality of a surface water environment. The method is used for treating river water. The method comprises the following steps: 1,arranging an aeration system and a waterweed-like filler; 2, debugging and culturing a microbial system; 3, continuously running the microbial system until treated river water reaches V-type water; 4,constructing a water ecological system; and 5, continuously running the water ecological system until the treated river water reaches IV-type water. The method adopts in-situ treatment to purify water, so no land is occupied, and the energy consumption is equal to or lower than that of a source-control and dirt-interception constructed sewage treatment facility; the bottom of the water is aeratedto consume sediment in situ, so sediment improvement is facilitated, and desilting investment is greatly reduced or desilting is avoided; microbial florae are enriched through natural aeration, so the water treatment effect is good; the water ecological system is constructed, so the self-purification capability of the water is brought into full play, and water eutrophication is prevented; and thesystem has the advantages of automatic operation, convenience in management, and unattended operation.

Description

technical field [0001] The invention relates to the field of river basin management of water treatment, in particular to an in-situ treatment method for improving the environmental quality of surface water. Background technique [0002] Through a large number of investigations, it is found that a considerable number of water bodies in my country generally have black and odorous phenomena, and the surface water environment in villages and towns is extremely bad. According to the "2015 China Environmental Status Bulletin" promulgated by the Ministry of Environmental Protection of China, in 2015, 9.7% of the country's surface water was inferior to Class V water bodies; local surveys confirmed that nearly 2,000 urban black and odorous water bodies, especially urban inland rivers and lakes, Its pollution load is even more serious. Therefore, the management of the surface water environment in the basin is imminent, and it is also a major trend in the direction of environmental ...

Problems solved by technology

At present, as the national policy is tilted towards the black and odorous water body and the surface water environment of the basin, many units or consortiums have conducted in-depth research on the treatment of the surface water environment in the basin, but the governance ideas are basically "controlling source and intercepting sewage + water ecology" However, source control and interception involves multiple point source and non-point source pollution in the watershed, which is large in volume, wide in scope, expensive and energy consuming
