Urban sewage tail water upgrading treatment system and use method thereof

Abstract

The invention discloses an urban sewage tail water upgrading treatment system and a use method thereof, and belongs to the technical field of tail water upgrading, the urban sewage tail water upgrading treatment system comprises a primary filter tank, a deep filter tank, a primary sedimentation tank, a biochemical reaction tank, a secondary sedimentation tank, a biological aerated filter, a suspended matter cleaning filter, a disinfection tank and a plurality of connecting pipelines, the deep filter tank is located beside the preliminary filter tank, the primary sedimentation tank is arranged beside the deep filter tank, the biochemical reaction tank is located beside the primary sedimentation tank, the secondary sedimentation tank is arranged beside the biochemical reaction tank, the biological aerated filter is located beside the secondary sedimentation tank, and the suspended matter cleaning filter is located beside the biological aerated filter. According to the sewage treatment device, the suspended solids in sewage treatment can be cleaned up through mutual operation of all the equipment, and the treatment efficiency of the suspended solids in the sewage is improved.

Description

technical field [0001] The invention relates to the technical field of tail water standardization, in particular to a treatment system for tail water standardization of urban sewage and a method for using the same. Background technique [0002] With the rapid development of population and social economy, the discharge of industrial wastewater and domestic sewage is increasing day by day. The construction and operation of sewage treatment plants have reduced the pollution load of sewage and wastewater on surface water to a certain extent. At present, most sewage treatment plants implement the first-level B or first-level A discharge standards in the national "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002), and the tail water is basically discharged directly into the sewage body. According to the "Surface Water Environmental Quality Standards" (GB3838-2002), the minimum standard for surface water is Class V water, which is mainly applicable to ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned patent still has the following problems in the treatment of sewage: in the process of upgrading the sewage tail water, because there are more suspended solids in the discharged sewage, the suspended solids in the sewage cannot be effectively collected Some of the suspended solids may be discharged during treatment, which will affect the standard upgrading operation of the tail water
