Control system for combined drainage pipe network without sewage trunk pipe and control method of control system

Abstract

The invention discloses a control system for a combined drainage pipe network without a sewage trunk pipe and a control method of the control system. The pipe network control system is suitable for unit areas without a sewage trunk pipe, according to the division, the unit areas are land areas comprising structures which are divided by according to functional purposes or rainwater and sewage pollution degrees with the same or similar attributes in an urban area, and the structures are one or the combination of two or more of villages in a city, residential communities, industrial and mining enterprises, organs, schools, hospitals, shopping malls or other unit areas possibly generating a large amount of sewage; the technical scheme is particularly suitable for transformation of an existingdrainage pipe network system of the villages in the city without the sewage trunk pipes. The control system provided by the invention is simple in structure and convenient to construct, the accurate control over the sewage and initial rainwater in each area can be realized only by constructing a water treatment system and an integrated water purification system in a limited area of the municipal road, so that the purpose of efficiently treating the rainwater and sewage is achieved.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a combined drainage pipe network control system for non-sewage main pipes 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 domestic 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 munic...
