Suspended matter separating well for separate system rainwater drainage system

Abstract

The invention discloses a suspended matter separating well for a separate system rainwater drainage system. The suspended matter separating well is provided with a water inlet and a water outlet, wherein the water inlet and the water outlet are arranged oppositely in the horizontal direction. The connection line between the water inlet and the water outlet is a water passing path. A water distributing area, a suspended matter separating area and a cleaning and digging area are sequentially communicated in the water passing path direction and arranged inside the suspended matter separating well. A mud depositing area is arranged below the suspended matter separating area. The suspended matter separating area is divided into a plurality of channels parallel with the water passing path through a folded plate assembly. The folded plate assembly comprises at least two folded plates arranged in parallel. The folded plates are vertically arranged in the suspended matter separating area. On the basis of an original rainwater well, by utilizing a shallow pool principle and arranging the folded plate assembly, the suspended matter separating well promotes suspended matter in rainwater to be deposited and separated in the suspended matter separating well effectively and achieves control over pre-pollution of the rainwater.

Description

Technical field [0001] The invention relates to a suspended solids separation well at the end of a split rainwater drainage system, in particular to a device for controlling initial rainwater pollution at the end of a straight-drainage split rainwater drainage system. Background technique [0002] Suspended matter is one of the important pollutants in rainwater runoff. Urban rainwater runoff contains a large amount of suspended matter. It mainly comes from debris generated by the corrosion of vehicles, exhaust gas from motor vehicles, atmospheric dry and wet sediments, tires and Materials produced by brake friction and smoke and dust released by residents’ chimneys. In addition to its own pollution, the suspended matter also adsorbs many other pollutants (such as heavy metals, etc.), especially suspended particles with a large specific surface area. Before the rainwater runoff in the drainage pipe network is discharged into the receiving water body, the effective removal of susp...
