In-situ treatment method for improving quality of water environment

Abstract

The invention discloses an in-situ treatment method for improving the quality of a water environment. The in-situ treatment method is used for treating a river channel water body and comprises the following steps: firstly, laying an aeration system and aquatic plant-imitated filler; secondly, debugging and training a microbial system; thirdly, continuously operating the microbial system until a governed river channel water body reaches V type water body; fourthly, constructing a water ecosystem; fifthly, continuously operating the water ecosystem until the governed river channel water body reaches IV type water body. According to the method, a water body is treated and purified by adopting an in-situ treatment mode, and land is not occupied; energy consumption is equivalent to or lower than that of a water treatment facility of source controlling and sewage intercepting construction; the bottom of the water body is aerated, and bottom mud is consumed in situ, so that the improvement on bottom sediment is facilitated, and desilting investment is greatly reduced or desilting is avoided; microbial communities are enriched by natural aeration, and the treatment effect of water quality is good; the water ecosystem is constructed to sufficiently realize the self-cleaning capability of the water body and prevent and control eutrophication of the water body; the in-situ treatment method is automatically operated and convenient to manage, and can realize 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] On April 16, 2015, the State Council officially promulgated the "Water Pollution Prevention and Control Action Plan", namely the "Water Ten Measures", which includes regulations specifically aimed at remediating black and odorous water bodies in cities, requiring municipalities, provincial capitals, and cities with separate plans to build up areas in 2017. By the end of the year, black and smelly water bodies will be basically eliminated, and there will be no large-scale floating objects on the river surface, no garbage on the river bank, and no illegal sewage outlets; the goal of black and smelly water body treatment will be completed by the end of 2020. In September 2015, led by the Ministry of Housing and Urban-Rural Development, together with the Ministry...

AI Technical Summary

Problems solved by technology

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
