Black and odorous river water treatment methods

Abstract

The invention discloses a method for treating black and odorous river water, which comprises the following steps: S1 divides the section of the river to be treated into multiple treatment units, extracts water samples from each treatment unit for COD testing, and divides them into multiple corresponding grades; S2 After the sewage pipe is closed, dredging is carried out in the treatment unit; after the desilting treatment in S2 is completed in S3, the water sample COD test is carried out for each treatment unit and reclassified into multiple corresponding levels; S4, according to the different levels of the treatment unit , carry out corresponding water quality treatment on the river water body; S5, follow-up treatment and operation and maintenance. Through the above settings, the river water body is divided into multiple levels and correspondingly treated separately. First, the water bodies in each part can obtain similar treatment effects, and at the same time can save a large cost. Secondly, the treatment requirements for different water bodies can be adjusted according to different levels. steps or reagents.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method for controlling black and odorous river water. Background technique [0002] With the development of society, although the economy is constantly advancing, it will always bring about various environmental damages to a certain extent, and the ecological environment is a vital living condition for living residents. Nowadays, the water bodies of rivers in many cities are severely damaged, and the ecological system is facing collapse. They lose their self-purification ability, and often gradually turn into black and smelly water bodies, such as low-quality water bodies that cannot survive plants and fish and shrimp organisms, which have a very bad impact on people's lives. . [0003] For example, the Chinese patent whose application publication number is CN106557029A discloses a method for controlling and controlling the pollution of black and odorous rivers....

AI Technical Summary

Problems solved by technology

[0004] According to the technical means proposed in the above scheme, the water quality of the entire river can be monitored in real time, and it is also easy to grasp the change of the river water after treatment. However, the above scheme does not provide reasonable and effective measures for water treatment. For the pollution control and treatment of rivers, the treatment of black and odorous water bodies is not only important, but also fast and effective
