Treatment method for improving environment quality of riverway water body

Abstract

The invention discloses a treatment method for improving the environmental quality of a riverway water body. The method is used for treating a riverway water body and comprises the following steps: 1,arranging an aeration system and a waterweed simulating filler; 2, debugging and culturing a microbial system; 3, continuously operating the microbial system until the treated riverway water body reaches a V type water body; 4, constructing a water ecological system; and 5, continuously operating the water ecological system until the treated river water body reaches a IV type water body. According to the method, a water body is purified by in-situ treatment, so that no land is occupied, and the energy consumption is equal to or lower than v of source-control sewage interception construction sewage treatment facilities; aeration is conducted on the bottom of the water body, and sediment is consumed in situ, so that sediment quality improvement is facilitated, and desilting investment is greatly reduced or desilting is avoided; microbial flora is enriched through natural aeration, so that the water quality treatment effect is good; a water ecological system is constructed, so that the self-purification capacity of the water body is brought into full play, and water body eutrophication is prevented; and the method has characteristics of automatic operation and convenient management,and achieves 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 water environment quality. 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. At present, as the national policy is tilted towards black and odorous water bodies and the water environment of the basin, many units or consortiums have conducted in-depth research on the treatment of the water environment in the basin, but the governance ideas are basically "controlling source pollution + water ecological restoration". , but 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. Contents of the invention [0003] Based on the problems existing in the prior ...
