Efficient sewage interception device and efficient sewage interception operation method for urban road gutter inlets

Abstract

The invention relates to an efficient sewage interception device and an efficient sewage interception operation method for urban road gutter inlets. The efficient sewage interception device comprisesa collecting well body and a water collecting pipe, wherein the collecting well body comprises an upper collecting well body and a lower collecting well body which are detachably connected into a whole vertically by insertion, and the bottom of the lower collecting well body is provided with a microorganism filler layer. A vertically two-section rainwater grate of a hanging-basket structure is mounted at the upper end of the upper collecting well body, and a vertical-flow sand settling device is arranged in the upper collecting well body and comprises a splayed reflecting component, a silt interception component of a rectangular pyramid and an anti-sludge resuspension component of an inverted square frustum structure which are arranged from top to bottom. The efficient sewage interceptiondevice integrating a gutter inlet sewage interception modification technology, the vertical-flow sand settling device and the bottom microorganism filler layer can intercept large solid pollutants, silt and other particles and can ecologically degrade the sludge deposited at the bottom.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a high-efficiency sewage interception device and an operation method for urban road rainwater outlets. Background technique [0002] The rainwater outlet is a facility for the pipeline drainage system to collect surface water. It is an auxiliary structure of the urban drainage system. It is mainly composed of water inlet grate, well body and branch pipes. Combined. Rainwater outlets are usually set at a certain distance in blocks, squares, street intersections and street gutters to collect rainwater on the ground to prevent rainwater from flooding roads and causing water accumulation in roads or low-lying areas to hinder traffic or damage roads. In the road drainage system, the rainwater outlet is not only the "throat" for the urban road rainwater pipe network to collect rainwater runoff, but also the main channel for non-point sour...

Problems solved by technology

However, according to the structure of the existing gullies, the transformation of the conventional sewage intercepting hanging basket technology to the sewage intercepting hanging basket has the defects of poor drainage and insignificant interception effect on sediment and other particles, which cannot meet the requirements of flood control and mud retention in the gully. Double requirements for particulate matter such as sand
