Region sectioning rainwater treatment system based on separate-system pipe network

Abstract

The invention relates to the field of urban rainwater treatment systems, in particular to a region sectioning rainwater treatment system based on a separate-system pipe network.The region sectioning rainwater treatment system comprises multiple sections divided according to area and a sewage manifold communicated with a sewage treatment plant, a sewage branched pipe, a rainwater branched pipe and at least one rainwater treatment facility are arranged in each section, each rainwater treatment facility is communicated with a discharging end of the corresponding rainwater branched pipe, a discharging end of each rainwater treatment facility is communicated with a natural water body, and a discharging end of each sewage branched pipe is communicated with the sewage manifold.The region sectioning rainwater treatment system is simple in structure, an urban water treatment system is divided into independent sections, and each rainwater treatment facility which is independent is arranged in the corresponding section, so that the delay problem in the process of long-distance delivery of early-stage rainwater in the prior art is solved, treatment pressure of the sewage treatment plant is reduced, the early-stage rainwater is avoided causing pollution to natural water, discharging treatment of rainwater is more reasonable and more efficient, and the region sectioning rainwater treatment system has high popularization value.

Description

technical field [0001] The invention relates to the field of urban rainwater treatment systems, in particular to an area-segmented rainwater treatment system based on diversion pipe networks. Background technique [0002] In the current society, urbanization is developing more and more rapidly, the area of ​​the city is getting larger and larger, the structure of the urban rainwater pipe network is becoming more and more complex, and the pressure on the urban rainwater treatment system is increasing. At present, there are three types of urban rainwater pipe network: diversion system, confluence system and mixed flow system. [0003] The early diversion water treatment system had a complete rainwater pipe network structure. The urban sewage system was completely separated from the rainwater pipe network. The urban sewage directly entered the sewage treatment system through the sewage pipe network for collection and treatment. The rainwater pipe network directly collected urba...

AI Technical Summary

Problems solved by technology

But for area M, a large amount of later clean rainwater in area M is also discharged into the urban sewage treatment system during the time when the storage tank discharges the initial rainwater in area N. Such discharge will cause great damage to the urban sewage system dealing with stress

In addition, the pipe network in M ​​area and N area is generally connected during actual operation. Due to the difference in distance and the retention effect on the road, the initial rainwater in N area may seriously pollute the later clean rainwater in M ​​area, which will also lead to rainwater discharge. The irrationality of the situation
