Sewage purifying device of municipal sewage pipe network

Abstract

The invention discloses a sewage purifying device of a municipal sewage pipe network. According to the device, a draining well and a checking well are dug in the ground and formed by adopting concretefor pouring, the side walls of the draining well and the checking well are both provided with a sewage inlet and a sewage outlet, and the draining well and the checking well are in series connectionwith a sewage draining pipeline through the sewage inlets and the sewage outlets; the upper opening of the draining well is covered by a rainwater strainer. By adjusting the rotation direction of screw conveyer vanes, the contaminants on the sewage feeding and discharging places of the checking well can all be conveyed into the checking well, and in this way, through cooperation of periodic cleaning, the solid contaminants can be effectively and fast cleaned out, and therefore primary cleaning of the contaminants in the pipe network can be achieved, the whole pipe network can be prevented frombeing blocked to the maximum limit in the process of draining the sewage into a sewage disposal plant in the latter period, and the frequency of manual dredging can be reduced.

Description

technical field [0001] The invention relates to the municipal field, in particular to a sewage purification device for a municipal sewage pipe network. Background technique [0002] Municipal sewage pipelines are mainly composed of drainage wells, inspection wells and sewage pipes. Drainage wells are mainly used to collect sewage, while inspection wells are used for pipeline cleaning and inspection. Inspection wells are mostly located at the corners of sewage pipes. This location is easy Accumulation and blockage of solid pollutants occur, so the setting of the inspection well is convenient for regular cleaning of pipeline blockages, but traditional cleaning is done manually, which is inefficient and prone to danger, but regular cleaning is prone to blockage of sewage pipes , thereby affecting the sewage transmission efficiency. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned situation, the present invention aims to provide...
