Double-layer regulation and storage tank for regulation and storage for flood peak and regulation and storage for initial rainwater

Abstract

The invention discloses a double-layer regulation and storage tank for regulation and storage for flood peak and regulation and storage for initial rainwater. The double-layer regulation and storage tank comprises a double-layer regulation and storage tank body, wherein a grid is arranged at the upstream of the double-layer regulation and storage tank body; the downstream of the double-layer regulation and storage tank body is connected with a pump station. According to the double-layer regulation and storage tank for regulation and storage for flood peak and regulation and storage for initialrainwater, by arranging the double-layer regulation and storage tank body, a water-passing corridor at a first underground layer, an air ventilating well, an air ventilating port at the first underground layer, an air ventilating port at a second underground layer, a water intake and drain gate of a regulation and storage tank body for flood peak, a downstream water drain gate, and a water intakegate of a regulation and storage tank body for initial rainwater in a cooperation use way, the problem of large land occupation area of the regulation and storage tank is solved; the double-layer regulation and storage tank for regulation and storage for flood peak and regulation and storage for initial rainwater has the advantages that the land occupation area is small, and the double functionsof regulation and storage for flood peak and regulation and storage for initial rainwater within the limited land usage range are realized; the practicality is improved, the regulation and storage capacity is greatly increased, the urban water drainage stress is relieved, the resource is saved, and the environment-friendly effect is realized; in addition, a water quality detector, an A / D (analog to digital) conversion module, a central processing unit, a power source module, a data comparison module and a data storage module are arranged.

Description

technical field [0001] The invention relates to the technical field of urban drainage engineering, in particular to a double-layer storage tank for flood peak regulation and storage and initial rainwater regulation and storage. Background technique [0002] With the development of urbanization, the runoff of rainwater increases. The peak flow of rainwater runoff is temporarily stored in the flood peak storage tank. After the flow drops, the water is discharged from the storage tank to reduce the peak flow and reduce the pump The scale of the station or the pipe diameter of the downstream rainwater main pipe can improve the drainage standard and waterlogging prevention capacity of the area, and reduce the waterlogging disaster; the initial rainwater pollutant concentration discharged by the diversion drainage system is very high, and the initial rainwater can be set near the rainwater discharge outlet of the drainage system The storage tank temporarily stores the initial rain...
