Distributing well with double flaps sluice gate and drainage system and drainage control methods thereof

Abstract

The invention discloses a distributing well with a double flaps sluice gate and a drainage system and a drainage control methods thereof, which is of an intelligent drainage effect. Reasonable water discharging is achieved by reasonably controlling the opening of a double flaps sluice gate of the drainage system through a control system, sewage and initial rainwater are enclosed to a storing and regulating facility to the most extent, while flood discharging is guaranteed. The drainage control methods comprise a water level method, a water quality method, a water quality-water level method, atime method, a total amount method, a rainfall method, a time-water level method, a total amount-water level method, and a rainfall-water level method. The phenomenons of water current cannot be limited in a intercepting sewer, and clean water and later rainwater are sent to a sewage treatment plant through an intercepting sewer of the prior art are effectively solved by the regulating of the methods. The sewage is enclosed to the storing and regulating facility to the most extent, and cleaner water is discharged to natural water body by reasonably controlling discharging routes of the sewage,the initial rainwater and the mid-term and later rainwater.

Description

technical field

[0001] The invention belongs to the technical field of drainage, and in particular relates to a diversion well with double flap gates, a drainage system including the diversion well and a drainage control method. Background technique

[0002] At present, the drainage system of cities and buildings mainly includes diversion system, confluence system and mixed flow system, the main purpose of which is to realize the collection, transportation and treatment of water bodies. For example, a system that treats all wastewater in one way is called combined. It has only one drainage system, called the confluence system, and its drainage pipe is called the confluence pipe. The system that treats different types of wastewater in different ways is called the diversion system, which generally has two drainage systems. One can be called a rainwater system, which is used to collect rainwater and industrial wastewater with a very low pollution level that is directly discha...
