Abstract

The invention discloses a completely separated system for controlling sewage and initial rainwater pollution and a control method of the completely separated system. The system comprises a sewage mainpipe and a rainwater main pipe, and further comprises at least one unit area, wherein a sewage treatment plant is arranged on an outlet of the sewage main pipe; an outlet of the rainwater main pipe communicates with a natural water body; a sewage branch pipe and a rainwater branch pipe are arranged in each unit area; an outlet of each sewage branch pipe communicates with the sewage main pipe; a first online rainwater treatment facility is arranged on an outlet of each rainwater branch pipe; and a first sewage discharge pipeline, which communicates with the sewage main pipe, and a first rainwater discharge pipeline, which communicates with the rainwater main pipe, are arranged on an outlet of each first online rainwater treatment facility. The completely separated system provided by the invention is simple in structure and convenient in installation and arrangement; and urban area pollution sources can be effectively controlled and initial rainwater can be precisely collected, so thatthe efficiency and the precision of water body treatment can be improved.

Description

technical field [0001] The invention relates to the field of municipal drainage systems, in particular to a complete diversion system for controlling sewage and initial rainwater pollution and a control method thereof. 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, which seriously pollutes the receiving water body. Many old cities at home and abroad are almost Take this approach. 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 comb...
