Method for comprehensively treating pollution of river and canals in city

Abstract

The invention relates to the technical field of water environment protection and water ecology remediation, and specifically relates to a method for comprehensively treating pollution of river and canals in city. The method is characterized in that water quality monitoring and pollutant source analyzing, pollution control and stream intercepting engineering, sponge city reconstruction engineering,primary rainwater treatment station construction, primary rainwater treatment, bottom sludge removing engineering, ecological remediation engineering, water cleaning engineering and protection bank treatment and control engineering are carried out to realize comprehensive treatment. According to the method, the technical measures of all engineering are selected and matched on the basis of the water quality monitoring result and the pollutant source analyzing result, so that the logical rationality of each measure can be ensured to the maximum, and the effect of complementing advantages of themeasures can be achieved; the current circumstances of simple engineering technology or low logic complementing performance of the engineering technologies in an original water pollution treatment scheme can be extremely reduced; the pollutants distributed along the banks can be effectively reduced; the water quality of the river and canals can be improved; and meanwhile, the water quality is stable and reaches the standard effectively for a long term.

Description

technical field [0001] The invention relates to the technical field of water environment protection and water ecological restoration, in particular to a method for comprehensive pollution control of urban river canals. Background technique [0002] The problem of environmental pollution in my country is still very serious at present, and water environment problems are closely related to people's lives: the continuous deterioration of water quality affects the safety of water intake and water use; changes in the water volume and water level of rivers and canals affect the frequency of waterlogging in cities; The absence greatly affects the quality of life of nearby residents. Therefore, improving the water quality of urban rivers and canals and improving the environmental conditions of canals are the contradictions and problems that many large and medium-sized cities that are currently developing rapidly need to face and urgently need to be solved. However, most of the existi...

Problems solved by technology

[0008] Aiming at the contradiction between the generally poor water quality of rivers and canals in cities and the residents' demand for a good water environment, the present invention provides a method for comprehensive pollution control of rivers and canals in cities. The method is based on water quality monitoring and pollutant source analysis. According to the typical pollutants of the water body (usually the pollutants with the highest exceeding multiples) and the corresponding pollution sources, carry out scientific matching of engineering and technical measures (including the sequence of measures and implementation intensity) to ensure the coordination among multiple measures The effect can realize complementary advantages
