Gutter inlet initial rainwater accurate diversion and treatment system

Abstract

The invention discloses a gutter inlet initial rainwater accurate diversion and treatment system. The system comprises a gutter inlet initial rainwater accurate diversion device and a slag removal filtering device, wherein a dry season cabin and a rainy season cabin are arranged in a box body of the gutter inlet initial rainwater accurate diversion device; a first drainage pipe and a second drainage pipe are arranged at the bottoms of the dry season cabin and the rainy season cabin respectively; and the first drainage pipe and the second drainage pipe are provided with a normally-closed firstvalve and a normally-closed second valve respectively. The slag removal filtering device comprises a first treatment chamber and a second treatment chamber, a pre-sedimentation tank and a filtering tank are arranged in the first treatment chamber, the second treatment chamber comprises a sediment sedimentation area and a centrifugal filtering area, and the first drainage pipe and the second drainage pipe communicate with a water inlet of the slag removal filtering device. According to the gutter inlet initial rainwater accurate diversion and treatment system, rainwater can be accurately diverted, rainwater which is small in pollution and meets the emission standard can be directly discharged, rainwater which is serious in pollution can enter the slag removal filtering device through the valves in the gutter inlet initial rainwater accurate diversion device, and solid impurities in sewage are effectively removed.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a precise diversion and treatment system for initial rainwater at a gully. Background technique [0002] With the gradual improvement of urban municipal facilities, only stormwater outlets are allowed to discharge into rivers in most places, and there are still flood discharge box culverts in some areas (more common in mountainous cities). Due to the wrong and random connections in the implementation and operation of the pipe network, part of the sewage enters the river with the rainwater pipes or flood discharge box culverts. In river governance, if the misconnection of the rainwater pipeline / discharge box culvert can be effectively controlled, it will be the most effective way to control the pollution of the river, but the investigation of the pipe network is difficult, and the misconnection in the subsequent construction cannot be eliminated Random connection problem.
