Description

A Sponge City Rainwater Purification and Treatment Diversion Device

technical field

The invention relates to the technical field of rainwater purification and treatment, in particular to a spongy city rainwater purification treatment and diversion device.

Background technique

In the current sponge city, the diversion and evolution of rainwater and sewage are often faced. In the process of drainage and flood discharge, it is often necessary to divert rainwater according to the flow and peak value of water. The diversion of rainwater and sewage is a kind of drainage. According to different drainage systems of pipeline systems, rainwater treatment can be treated separately or in combination with domestic sewage and industrial wastewater. The water volume of rainwater treatment is calculated according to the rainwater channel. The diversion drainage system often uses two or more channels. The system collects, transports and disposes rainwater or sewage of different natures and flows respectively. The diversion system is divided into two types of drainage systems: complete diversion system and incomplete diversion system according to the different ways of excluding rainwater. The drainage system has both a sewage drainage system and a rainwater drainage system. The invention patent with the application number ZL201810690856.4 discloses a diversion device, a diversion system and a diversion method, including: a diverter body with an inlet and an outlet and a bypass outlet Pipe; a pneumatic expansion assembly, arranged in the shunt body, used for expanding or contracting under the action of compressed gas to correspondingly make the pipeline cut off or conducting, wherein the pneumatic expansion assembly includes an airbag arranged in the bypass outlet pipe , the air bag has a connection port for communicating with the compressed air source through the gas delivery pipeline. When the air bag is inflated, the inflated air bag will expand to completely block the bypass outlet pipe, so that the bypass outlet pipe is in a cut-off state, The invention patent with the application number of ZL201811340598.3 discloses a diversion well, including a diversion well body and an overflow weir, which can realize initial rainwater collection, medium-term rainwater discharge and excessive rainwater storage, especially suitable for downstream pipelines with limited scale.
