Method for in-situ treatment of water environment quality

Abstract

The invention discloses a method for in-situ treatment of water environment quality. The method is used for treating a riverway water body and comprises the following steps: step 1, arranging an aeration system and a waterweed-like filler; step 2, debugging and culturing a microbial system; step 3, continuing to operate the microbial system until the treated riverway water body reaches a V type water body; step 4, constructing a water ecological system; and step 5, continuing to operate the water ecological system until the treated river water body reaches a IV type water body. According to the method, the water body is purified by in-situ treatment, no land is occupied, the energy consumption is equal to or lower than that of source-control sewage interception construction sewage treatment facilities; aeration is conducted on the bottom of the water body, sediment is consumed in-situ, sediment improvement is facilitated, and desilting investment is greatly reduced or desilting is avoided; microbial flora is enriched through natural aeration, the water quality treatment effect is good; a water ecological system is constructed, the self-purification capacity of the water body is fully exerted, and water body eutrophication is prevented; automatic operation is achieved, management is convenient, and unattended operation can be achieved.

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 ...
