Method for controlling sewage in rainwater pipelines and sewage pipelines in all areas in drainage system to flow into regulation and storage facility during rainfall

Abstract

The invention discloses a method for controlling sewage in rainwater pipelines and sewage pipelines in all areas in a drainage system to flow into a regulation and storage facility during rainfall. According to the method, under the condition that existing resources are utilized to the greatest extent, through reasonable allocation, the initial rain, which is poor in water quality and serious in pollution, in all the areas are discharged into the regulation and storage facility through pollution interception pipes connected with the rainwater pipelines, and meanwhile, the sewage in sewage pipes connected with the sewage pipelines are discharged into the regulation and storage facility, and then the initial rain and the sewage enter a sewage treatment plant for treatment. When the amount ofthe sewage, in the sewage pipes connected with the sewage pipelines and in the pollution interception pipes connected with the rainwater pipelines enter, flowing into the regulation and storage facility is reasonably allocated, the level of pollution of the sewage to the areas is reduced to the greatest extent, meanwhile, the clean rainwater is not discharged into the sewage treatment plant, theload of the sewage treatment plant is reduced, and therefore, the reasonable discharging of the water is achieved.

Description

technical field [0001] The invention belongs to the technical field of regulation and control of drainage systems, and in particular relates to a method for controlling the flow of sewage in rainwater pipelines and sewage pipelines in various areas in a drainage system into regulation and storage facilities during rainfall. 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 drainage pipe network is becoming more and more complex, and the treatment pressure of the urban water treatment system is increasing. [0003] The traditional urban pipe network system uses a large rainwater treatment system to be responsible for a large catchment area. Because the catchment area is too large, the delay time of rainwater in the pipeline or surface runoff is not fully considered, resulting in initial rainwater Mixed with the later rainwater in large quantiti...

Problems solved by technology

However, such a pipe network system is usually suitable for sunny days. When rain falls, due to the limited processing capacity of the sewage treatment plant in the pipe network, the maximum flow rate of the sewage interception box culvert is limited; The water bodies in each unit area are discharged to the sewage treatment plant at the same time, resulting in different degrees of waterlogging disasters in each unit area
