An integrated device for sand settling and pollution prevention suitable for river channel treatment projects

Abstract

The invention discloses a sand-settling trash-holding all-in-one device suitable for the river controlling project. The sand-settling trash-holding all-in-one device comprises a riverway region and a treatment region, wherein the riverway region is a partial drainage area cut out from a to-be-controlled riverway; the treatment region is positioned in a shoreside region of the to-be-controlled riverway, and the treatment region and the riverway region are arranged side by side; a hydraulic gate is arranged in the riverway region for dividing the riverway region into an upstream region and a downstream region; the treatment region comprises an inlet and an outlet; the treatment region communicates with the upstream region through the inlet, and communicates with the downstream region through the outlet; a coarse-slit grid is arranged in the inlet; a middle filter chamber is arranged in the treatment region; a rotary grid is mounted in the middle filter chamber; a quick-closing type channel grate is separately arranged at each of the front end part and the rear end part of the middle filter chamber; the lower end of the rotary grid abuts against the bottom wall of the middle filter chamber; and the upper end of the rotary grid passes through the top wall of the middle filter chamber, and communicates with a garbage disposal system. The sand-settling trash-holding all-in-one device can be applied to comprehensive improvement of a black-odor urban river very well.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated sand settling and pollution blocking device suitable for river channel treatment projects. Background technique [0002] With the rapid advancement of urbanization and industrialization in my country, the quality of water environment is declining day by day, and the number of black and odorous water bodies is increasing day by day. The Suzhou River in Shanghai was the earliest research object of black and odorous water in my country. Subsequently, the Huangxiao River in Wuhan, the Outer City River in Suzhou, the Qinhuai River in Nanjing, and the Inner River in Ningbo also appeared black and odorous phenomena to varying degrees. In the past half century, the scope and degree of black and odorous water bodies have continued to intensify. Most of the water bodies flowing through prosperous areas in the country have been polluted to varying degrees, and black a...

Problems solved by technology

Conventional endogenous treatment mostly adopts manual salvage of floating objects, garbage and manual dredging. This method is not only inefficient, but also causes a large amount of pollutants to enter the water body due to disturbance in the manual dredging process, affecting the stability of the water body ecosystem.
