Abstract

The invention discloses a scope pollution control system and method used for a separate system drainage pipe network system. The scope pollution control system comprises a sewage dry pipe and a rainwater dry pipe; a sewage treatment plant is arranged at an outlet of the sewage dry pipe; an outlet of the rainwater dry pipe is communicated with a natural water body, a second rainwater treatment system is arranged on the rainwater dry pipe, the water inlet end of the rainwater treatment system is communicated with the rainwater dry pipe, and the drainage end of the rainwater treatment system is communicated with the sewage dry pipe. The scope pollution control system is simple in structure and convenient to build, sewage and initial rainwater in all areas which are divided according to administrative functions in a city can be efficiently treated simply by building an initial rain storage pond in a limited area of a municipal administration road.

Description

technical field [0001] The invention relates to a surface pollution control method, which belongs to the technical field of decentralized source surface pollution control, and in particular to a surface pollution control system and method for a diversion system drainage pipe network system. Background technique [0002] Urban municipal drainage systems are mainly divided into combined drainage systems and divergent drainage systems. The first combined drainage system that appeared was to mix domestic sewage, industrial wastewater and rainwater in the same pipe, and directly discharge it into the nearby water body without any treatment, which seriously polluted the receiving water body. Many old cities at home and abroad almost All in 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 in...
