Abstract

The invention discloses an incompletely separated disposal system for controlling sewage and initial rainwater pollution and a control method thereof. The system comprises a sewage main sewer and a rainwater main sewer. An outlet of the sewage main sewer is provided with a sewage treatment plant. An outlet of the rainwater main sewer is communicated with a natural water body. The system also comprises at least one unit area. A sewage branch sewer, a rainwater branch sewer and a combined sewer are disposed in each unit area. An outlet of each sewage branch sewer and an outlet of each rainwaterbranch sewer are communicated with an inlet of the corresponding combined sewer. An outlet of each combined sewer is provided with a first online rainwater treatment facility. An outlet of each firstonline rainwater treatment facility is provided with a first sewage discharge pipe communicated with the sewage main sewer, and a first rainwater discharge pipe communicated with the rainwater main sewer. The incompletely separated disposal system is simple in structure and convenient to install and arrange, urban non-point pollution sources can be effectively controlled, initial rainwater can beaccurately collected, and water body treatment accuracy can be improved.

Description

technical field [0001] The invention relates to the field of municipal drainage systems, in particular to an incomplete 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 c...
