Process for improving quality and efficiency of discharge standard of municipal sewage treatment plant

Abstract

The invention discloses a quality-improving and efficiency-improving process for the discharge standard of a municipal sewage treatment plant, which comprises a treatment box, two vertical plates are fixedly arranged in the treatment box, side connecting frames are fixedly arranged between the two side ends of the vertical plates and the treatment box, and a transverse plate and a material gathering hopper are fixedly arranged between the opposite ends of the two vertical plates and the treatment box respectively; and a part for containing filtered sand is arranged in the sliding connection frame, and a part for controlling the top frame plate to vertically move is arranged at the inner top of the treatment box. According to the sewage treatment device, firstly, through a three-in-one sewage treatment process, the sewage treatment efficiency and quality are improved, meanwhile, the equipment purchase cost and the site occupation cost of manufacturers are reduced, secondly, the top frame plate drives the two sliding connection frames fixed to the top frame plate to vertically move downwards, switching of the filtering cavities is achieved, and the filtering efficiency is improved. The filtering chambers are intermittently switched, so that the filtering mechanism can continuously and effectively filter sediments in the sewage.

Description

technical field [0001] The invention relates to the technical field of sewage discharge treatment, in particular to a process for improving the quality and efficiency of the discharge standards of urban sewage treatment plants. Background technique [0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage within the scope of urban areas. Generally, it is collected by urban pipes and canals and should be treated by urban sewage treatment plants before being discharged into water bodies. In addition to containing a large amount of organic matter, germs and viruses in urban sewage, due to the high development of industry, the volume of industrial wastewater (accounting for about 60-80% of the total urban sewage), the water quality is becoming more and more complex and the pollution of runoff sewage is becoming more and more serious, making urban sewage Contains various types and degrees of various toxic and harmful pollutants. [0003] In order ...

AI Technical Summary

Problems solved by technology

[0003] In order to meet the indicators of sewage discharge in the existing urban sewage treatment, it is often necessary to set up multiple different types of sewage treatment equipment in the process of treatment. Through flocculation and sedimentation of sewage, after the sediment is removed, it is necessary to use aeration equipment to remove the sewage from the sewage. The harmful chemical substances are removed, and finally they can be discharged outside after being detected by the detection system. Through the decontamination treatment of sewage in various ways, manufacturers need to purchase a variety of corresponding treatment equipment. In terms of equipment laying site and procurement, It often requires high cost. Secondly, after the harmful impurities in the sewage form sediment, the sewage can be effectively removed by filtering the sand. However, it is difficult for the existing urban sewage treatment institutions to The filter sand that filters more sewage should be cleaned and replaced in time. The accumulation of more impurities in the filter sand will cause the flow of sewage to be blocked. If the impurities in the filter sand are not cleaned in time, it will easily affect the flow rate of sewage, which is not conducive to sewage impurities. Rate and effectiveness of precipitate removal
