Problems solved by technology

[0004] For this combined drainage system, the main problems are: ① When it rains, non-point source pollution will be generated on residential areas and municipal roads. Although the existing combined drainage system has an interception well at the end for interception, the designed interception The multiple is not enough, so that the interception well fails to intercept the non-point source pollutants, and the non-point source pollutants directly enter the natural water body, causing pollution to the natural water body
② To control non-point source pollution, it is necessary to increase the size of the interception well, increase the size of the interception main pipe, and increase the capacity of the sewage plant
③ The interception of the interception well is controlled extensively, and the initial rainwater cannot be accurately intercepted
There are many problems in this split drainage system: ① Some sewage in the residential area enters the rainwater pipe by mistake, for example, the sewage discharged from the washing machine on the balcony will be directly discharged into the natural water body
The main problems of this drainage system are: ①The entire system cannot effectively intercept non-point source pollutants, and the interception efficiency is low
② Unable to control the sewa

Embodiment 1

[0069] Such as figure 1 The shown residential sewage and rainwater diversion system drainage system, the system includes: the main sewage pipe B-1 on the municipal road, the outlet of the main sewage pipe B-1 is provided with a sewage treatment plant 2, the sewage treatment The outlet pipe of plant 2 is connected with natural water body 1 through biofilter 6;

[0070] The rainwater main pipe B-2 on the municipal road, the end of the rainwater main pipe B-2 is connected with the natural water body 1;

[0071] The sewage pipe A-1 in the community A is connected to the main sewage pipe B-1;

[0072] The rainwater pipeline A-2 in the community A is connected to the water inlet of the diversion well 3, the first water outlet of the diversion well 3 is connected to the sewage main pipe, and the second water outlet of the diversion well 3 is connected to the rainwater main pipe B-2, and , the first water outlet of the diversion well 3 is provided with a bottom-opening weir gate 4 ,...

Embodiment 2

[0079] The control method of the diversion drainage system using the community sewage and rainwater of embodiment 1 is:

[0080] On sunny days, the bottom-opening weir gate 4 is opened, the bottom-opening gate 5 is closed, and the sewage from the sewage pipeline flows into the sewage treatment plant through the main sewage pipe for treatment; The main sewage pipe enters the sewage treatment plant for treatment;

[0081]During the initial rainfall, the bottom-opening weir gate 4 is opened, the bottom-opening gate 5 is closed, and the sewage in the sewage pipeline flows into the sewage treatment plant through the main sewage pipe for treatment; The mixed sewage formed by the rainwater enters the sewage treatment plant for treatment through the bottom opening weir gate 4 and the main sewage pipe;

[0082] During the middle and later periods of rainfall, when the water volume exceeds the maximum flow rate of the interceptor pipe leading to the sewage treatment plant, the lower op...

Abstract

The invention provides a sewage and rainwater diversion drainage system, comprising a sewage main pipe on a municipal road, the outlet of the sewage main pipe is provided with a sewage treatment plant; a rainwater main pipe on the municipal road, the rainwater main pipe The end is connected with the natural water body; the rainwater pipeline and sewage pipeline in the unit area, the sewage pipeline is connected with the sewage main pipe; the outlet of the rainwater pipeline is provided with a rainwater treatment system, and the rainwater treatment system includes a diversion device; the rainwater pipeline and the diversion The water inlet of the device is connected, the first water outlet of the diversion device is connected with the sewage main pipe, and the second water outlet of the diversion device is connected with the rainwater main pipe. The system of the present invention is simple in structure and convenient in construction, and only needs to build diversion equipment in the limited area of ​​the community to realize efficient treatment of mixed sewage in the area of ​​the community.

Description

technical field [0001] The invention relates to a diversion drainage pipe network system, in particular to a diversion drainage system and control method for sewage and rainwater. Background technique [0002] Urban municipal drainage systems are mainly divided into combined drainage systems and divergent drainage systems. The earliest combined drainage system is to mix sewage, industrial wastewater and rainwater in the same pipe, and directly discharge it into the nearby water body without any treatment, so that the receiving water body is seriously polluted. Many old cities at home and abroad almost use it this way. The interception combined drainage system is often used now. [0003] The structure of the intercepting combined drainage system is basically the same as that of the traditional combined drainage system. The difference is that the intercepting combined drainage system has an intercepting well between the municipal combined main pipe and the sewage treatment p...
