Rainwater and sewage treatment system based on multi-point mixed drainage and regulation and storage

Abstract

The invention relates to a rainwater and sewage treatment system based on multi-point mixed drainage and regulation and storage. The system comprises an intelligent intercepting well and an initial rainwater regulation and storage sewage intercepting chamber which are communicated with each other. The intelligent intercepting well discharges sewage or rainwater entering from the treatment drainageport to the initial rain regulation and storage sewage intercepting chamber through the sewage intercepting pipeline during dry season pollution discharge or rainy season initial rain; and the initial rainwater regulation and storage sewage interception chamber is used for pretreating sewage discharged by the intelligent intercepting well and then discharging the pretreated sewage to the sewage treatment plant, or the initial rainwater in the rainy season is treated and then stored. Sewage in dry seasons and initial rain in rainy seasons are intercepted by the intelligent intercepting well and are converged into the initial rain regulation and storage sewage intercepting chamber, rainwater in the later period of initial rain in the rainy season is discharged to the water body, the initialrain regulation and storage sewage interception chamber primarily treats sewage and then discharges the sewage to the sewage treatment plant, the initial rain is treated and then stored, dry season sewage interception of a mismixed rainwater outlet and collection of initial rainwater in the rainy season are achieved, pollution to the receiving water body is reduced, and a guarantee is provided for water body quality improvement.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a rainwater sewage treatment system based on multi-point mixed drainage and regulation and storage. Background technique [0002] According to the classification of outlets in the "Urban Black and Odor Water Remediation—Technical Guide for Drainage Outlets, Pipelines and Inspection Wells", the outfalls are mainly divided into diversion system outfalls, combined system outfalls and other outfalls. The diversion system drainage outlet includes the diversion system sewage outlet: a drainage outlet that directly discharges sewage to the water body, which directly causes water pollution; diversion system rainwater outlet: a drainage outlet that directly discharges rainwater to the water body, because the quality of the rainwater discharged in the early stage of rainfall is poor, It will bring a certain degree of pollution to the water body; diversion system rain and sewage mi...

AI Technical Summary

Problems solved by technology

At present, there are no effective control measures for the initial rainwater pollution of the diversion system at home and abroad, and the initial rainwater pollution is still the focus and difficulty of water environment management
