Full-collection anti-blocking pollutant-intercepting hanging basket with non-point-source-pollution controlling function

Abstract

The invention discloses an anti-blocking pollutant-intercepting hanging basket with the non-point-source-pollution controlling function. The anti-blocking pollutant-intercepting hanging basket comprises a flow guiding frame and an anti-blocking pollutant intercepting basket, and the anti-blocking pollutant intercepting basket is connected with the flow guiding frame. When wastewater with solid particle or suspension pollutants enters a gutter inlet, flows through the flow guiding frame and enters the pollutant intercepting basket, the pollutants are intercepted and filtered out, the wastewater obtained after filtering converges into a rainwater pipeline through filtering holes or clear water grooves of the pollutant-intercepting hanging basket and flows away. When a filtering net is blocked, after the water level is increased to be at a certain height, siphoning is formed in a siphoning pipe, back flushing is started, and blocking of the filtering net is remitted. According to the anti-blocking pollutant-intercepting hanging basket, the solid particle pollutants and the suspension pollutants are intercepted in the pollutant-intercepting hanging basket of the gutter inlet, and water accumulation can be avoided; the back flushing function is achieved, the effects of preventing non-point source pollution, sedimentation, bad smells and mosquitoes and flies can be achieved, and the anti-blocking pollutant-intercepting hanging basket is of great significance in protecting water bodies and improving urban ecological environments. As the self-cleaning function is further achieved, the hanging basket can be effectively prevented from being blocked, and the service life and the maintenance and cleaning interval are prolonged.

Description

technical field [0001] The invention belongs to the field of road sewer pipe devices, and more specifically relates to a full-collection and anti-clogging rainwater outlet sewage intercepting hanging basket with the function of controlling surface source pollution. Background technique [0002] The rainwater outlet is the input end collected by the urban road sewer system. At present, the rainwater outlet used in China is composed of a well body, a well bottom and a rainwater grate. Most of the road drainage adopts the drainage method of "side ditch-rainwater outlet-connecting pipe-municipal pipeline". Rainwater enters rivers and lakes, causing water pollution; when rainwater is discharged into lakes and other static water bodies, it will cause sedimentation in the water body, and the water level will become shallower, requiring frequent dredging and spending a lot of manpower and material resources; The high concentration of solid particle pollutants and suspended pollutan...
