Road rainwater pneumatic shunting treatment system and control method thereof

Abstract

The invention relates to a road rainwater pneumatic shunting treatment system and a method thereof. The system comprises a compressed gas source, a gas conveying pipe and a shunting well arranged on amunicipal rainwater pipe; the shunting well comprises a well body structure, an inlet, a first water outlet pipe, a second water outlet pipe, a third outlet pipe and pneumatic cut-off devices, wherein the well body is at least provided with the inlet, the first water outlet pipe, the second water outlet pipe, and the third water outlet pipe; the pneumatic cut-off devices are arranged on the second water outlet pipe and the third water outlet pipe, and are respectively a second pneumatic cut-off device and a third pneumatic cut-off device; the inlet is communicated with the municipal rainwaterpipe at the upstream of the shunting well; the first water outlet pipe is communicated with the municipal rainwater pipe or a natural water body at the downstream of the shunting well; the second water outlet pipe is communicated with a municipal sewage pipe or a sewage treatment facility or a regulating storage tank; the third water outlet pipe is communicated with a primary rain pipe or the regulating storage tank or an initial rainwater treatment facility; a control valve, which comprises a second control valve and a third control valve, and the second control valve and the third control valve are respectively connected with the gas conveying pipe; the second control valve and the third control valve respectively control the charging and the discharging of the second pneumatic cut-offdevice and the third pneumatic cut-off device to be used for respectively controlling the cut-off and the conduction of the corresponding second water outlet pipe and the third water outlet pipe.

Description

technical field [0001] The invention relates to municipal rainwater and sewage diversion, in particular to a pipeline diversion system and method with one inlet and two outlets, belonging to the technical fields of civil buildings and municipal water supply and drainage. Background technique [0002] At present, in the diversion well, abandonment well and interception well system, the system is composed of water inlet pipe, outlet pipe and sewage pipe, and the domestic sewage in the drainage pipe or the initial rainwater and the later rainwater are diverted. Among them, the domestic sewage or The initial rainwater is intercepted to the sewage pipe and then transported to the sewage treatment plant for treatment and discharged after reaching the standard (further, the initial rainwater can be stored or intercepted to the sewage treatment plant for treatment and discharged after reaching the standard), and the middle and late rainwater is directly discharged into the natural wa...
