Abstract

The invention discloses a face pollution control method for a combined system drainage pipe network system. An urban region is divided into a plurality of unit regions including sewage pipelines and rainwater pipelines through function purpose attributes. The rainwater pipeline and the sewage pipeline inside each unit region are communicated. A first rainwater treatment system arranged on the sewage pipeline inside each unit region separates sewage inside the sewage pipe and mixed sewage formed by preliminary rainwater into a sewage branch pipe or a rainwater branch pipe to treat the mixed sewage inside the unit region, the mixed sewage is guided into the sewage branch pipe or the rainwater branch pipe; a second rainwater treatment system arranged on the rainwater branch pipe achieves treatment of mixed sewage inside the rainwater branch pipe, and the mixed sewage is guided into the sewage branch pipe or natural water is directly drained. The face pollution control method is simple in structure and convenient to build, and efficient treatment of sewage and preliminary rainwater inside the regions divided through administrative functions inside a city can be achieved just by building a preliminary rainwater storage pond inside the limited region of the municipal 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, in particular to a surface pollution control method for a combined drainage pipe network system. Background technique [0002] The urban municipal drainage system is mainly divided into combined drainage system and combined drainage system. 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 intercepting combined drai...
