Pollutant reduction combined device used in rainwater pumping stations, and technology thereof

Abstract

The invention belongs to the technical field of water, waste water, sewage, or sludge treatment, and more specifically relates to a pollutant reduction combined device used in rainwater pumping stations, and technology thereof. The pollutant reduction combined device comprises a forebay water in-situ treatment device, a forebay water ex-situ treatment device, and a gallery purifying device; the forebay water in-situ treatment device comprises an aeration device; the forebay water ex-situ treatment device comprises an elevator pump and a clarification device; the gallery purifying device comprises a trash holding wave dissipating screen, a biomembrane reactor, and an aeration system; and the gallery purifying device is arranged at a discharge opening. The pollutant reduction combined deviceis used for comprehensive purifying treatment of water body in rainwater pumping stations from forebay treatment to discharge, is capable of reducing pumping station sewage pollutant effectively, improving the quality of water discharged from rainwater pumping stations into rivers, improving black and odorous water in rivers with obvious effect, improving water transparency obviously, breaking nutrient balance, and inhibiting algae and eutrophication, is small in occupied area; discharge water is capable of reaching second grade water standards; distribution can be adjusted based on pumping station situations; the using amount of adopted agents is low; automatic control is realized; and operation and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of water, waste water, sewage or sludge treatment, in particular to a combined device for reducing pollutants used in a rainwater pumping station and a process thereof. Background technique [0002] The main causes of black and smelly urban rivers include pumping stations released into the river, unfavorable hydrodynamic conditions, poor upstream water source conditions, alienation of river channel functions, and destruction of aquatic ecosystems. Among them, the release of pumping stations into the river causes a large amount of exogenous pollutants to enter the river, domestic sewage, garbage and various heavy metals will cause the water to be black and smelly, which is the main reason for the sharp decline in the water quality of the river and turn it into a black and smelly water body. [0003] The main sources of pollution that the pump station enters into the river through the way of discharging into t...

AI Technical Summary

Problems solved by technology

[0006] 3. The main source of initial rainwater is surface runoff pollution and erosion pollution of pipelines

[0008] At home and abroad, there are few studies on the reduction of pollutants released by pumping stations into the river, and there is no relevant systematic research

On the one hand, due to the limitation of funds and implementation conditions, the promotion progress is slow; on the other hand, there is a lack of systematic research from the reduction of pollution sources to the treatment at the end of the river
