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

A rainwater outlet and road technology, which is applied in water supply installations, water/sludge/sewage treatment, water/sewage treatment, etc., can solve the problem that the interception effect of particles such as sediment is not obvious, the drainage is not smooth, and it cannot meet the flood control and pollution requirements of the rainwater outlet. Sediment and other problems are retained to achieve the effect of convenient maintenance, reduced pollution, and convenient assembly

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

Embodiment

[0040] Embodiment: The present invention is an integrated device that combines the sewage interception transformation technology of the rainwater outlet with the vertical flow sand settling device, aiming at efficiently intercepting large pollutants and small particle solid pollution without affecting the flood control function of the rainwater outlet It can purify the quality of rainwater entering the rainwater pipe network and reduce the pollution of rainwater runoff to urban water bodies. The present invention includes a collection well body. The collection well body includes an upper collection well body 10 and a lower collection well body 11 which are detachably plugged together. When in use, the upper collection well body 10 and the lower collection well body 11 are plugged together and Installed below the ground, rainwater, pollutants, etc. can flow downward from the upper opening of the upper collection well body 10 into the collection well body. The side wall of the co...

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...
