Method for control and treatment of water pollution of black and odorous river

Abstract

The invention discloses a method for control and treatment of water pollution of a black and odorous river. The method includes following steps: S1, dividing key river reaches or control units; S2, calculating water environment characteristics, and determining water quality targets of the control units; S3, calculating the water environment capacity and pollution load accounting according to the water quality targets; S4, distributing the pollution load cutting amount to each control unit; and S5, performing overall treatment layout, establishing a river water quality process model, putting treatment information into the model, inspecting whether the water quality targets reach the standard, if not, repeating the steps of S1-S5 until the water quality reaches the standard, and if yes, applying the method to practical water pollution treatment of black and odorous rivers. According to the method, the problem of treatment of the black and odorous water body is accurately quantified, key chemical indexes which cause the water body to become black and odorous are extracted, the setting of each treatment project and the specific project amount can be guided through quantitative calculation, and the project management is more accurate and economic.

Description

technical field [0001] The invention relates to the technical field of river water pollution control and treatment, in particular to a method for controlling and treatment of black and odorous river water pollution. Background technique [0002] In September 2015, the Ministry of Housing and Urban-Rural Development issued the "Guidelines for the Remediation of Urban Black and Odorous Waters"; the "Guidelines for the Remediation of Urban Black and Odorous Waters" applies to water bodies in urban built-up areas and is a guiding technical manual. At present, the treatment of black and odorous water bodies in my country is in the initial stage. In the actual operation process, the coverage of black and odorous water bodies is not only urban built-up areas, but also urban unbuilt areas, urban villages, rural areas around cities and other vast rural areas; The scope of application is relatively lacking. In addition, its binding indicators for black and odorous water bodies are tra...

Problems solved by technology

[0003] In March 2016, the Ministry of Environmental Protection issued the official version of the "Technical Guidelines for the Compilation of Water Standards Up to Standards Program". The "Technical Guidelines for the Compilation of Water Body Standards Up to Standards Program" is a general outline document, lacking specific ideas, processes and technical methods, especially for the design of water quality improvement programs for black and odorous rivers.

In addition, there is a lack of relevant guidance on the establishment of quantitative relationships between water environment issues, the scale and location of treatment projects, etc.
