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

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as Figure 1~3 In this embodiment, the entire water treatment area is divided into grids, and the area of ​​each area 19 is 0.2 to 4 square kilometers. Because of the small area, the rainwater has a short delay in the process of being transported to the rainwater treatment system, and there will be no phenomenon that it is difficult to separate the initial rainwater from the later clean rainwater.

[0032]The area 19 can be divided evenly, or it can be arranged according to the actual terrain. Each area 19 is connected through the sewage main pipe 20 to form an overall water treatment system. The area of ​​the area is divided according to 0.2-4 square kilometers. The sewage and initial rainwater in each area 19 is discharged to the sewage treatment plant 21 through the sewage main pipe 20 for comprehensive treatment. The...

Abstract

The invention relates to the field of urban rainwater treatment systems, in particular to a separate system pipe network based area fragmented rainwater abandoned flow treatment system. An area internally comprises a sewage header pipe, rainwater branch pipes and sewage branch pipes; the discharging ends of the sewage branch pipes are communicated with the sewage header pipe, the area is divided into a plurality of segments in a grid shape, and the area of each fragment is 0.2-4 square kilometers; each fragment is internally provided with a sewage branch pipe, a rainwater branch pipe and one or more abandoned flow wells; each abandoned flow well comprises a well body, each well body is provided with a water inlet pipe communicated with the discharging end of the corresponding rainwater branch pipe, a water outlet pipe communicated with natural water and an abandoned flow pipe communicated with the sewage header pipe. The separate system pipe network based area fragmented rainwater abandoned flow treatment system is simple in structure, the problem of delay in the long-distance conveying process of initial rainwater in the prior art is solved through the independent abandoned flow wells in the fragments, the treatment pressure of a sewage treatment plant is relieved, the situation that initial rainwater pollutes natural water is further avoided, and discharging treatment of rainwater is more reasonable and effective.

Description

technical field [0001] The invention relates to the field of urban rainwater treatment systems, in particular to an area-segmented rainwater waste flow treatment system based on a diversion pipe network. 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 co...
