Split-type air stripping membrane reactor treatment device

Abstract

The invention discloses a split-type air stripping membrane reactor treatment device. The split-type air stripping membrane reactor treatment device comprises a split-type machine cabinet, an air stripping membrane reactor membrane group, a water inlet system, a produced water system, a backwashing system, a self-use water tank, a control system and a sludge reflowing pipeline, wherein the front end and the back end of the water inlet system are communicated with a biological reaction system and the air stripping membrane reactor membrane group; the front end and the back end of the produced water system are communicated with the air stripping membrane reactor membrane group and a produced water tank; the front end and the back end of the backwashing system are communicated with the self-use water tank and the air stripping membrane reactor membrane group; the control system is connected with the other systems; the sludge reflowing pipeline is communicated with the biological reaction system; the air stripping membrane reactor membrane group comprises at least one internal pressure-type pressure container; at least ten membrane filaments are vertically arranged inside the pressure container. The split-type air stripping membrane reactor treatment device is simple in structure and strong in sewage treatment capacity, guarantees the pollutant intercepting uniformity of the membrane filaments in each membrane element, prolongs the service life of the membrane element and reduces the operating expense.

Description

technical field [0001] The invention relates to a filter device, in particular to a split-type air-lift membrane reactor treatment device. Background technique [0002] In recent years, in order to better protect the water environment, control environmental pollution, avoid eutrophication of water bodies and deterioration of water quality, and protect water resources, domestic provinces and cities have increasingly stringent requirements for domestic sewage discharge standards. For the wastewater discharge requirements of rivers, lakes and other basins where the receiving water body is, the standard has basically been raised from the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002) Grade A and Grade B standards to "Surface Water Environmental Quality Standards" (GB3838-2002) Class III or Class III or even higher water quality requirements. Faced with increasingly stringent sewage discharge standards, it has brought severe challenges to the se...

Problems solved by technology

In addition, due to the limitation of its operation mode, the submerged MBR treatment system mostly adopts civil structure, and its installation and use are greatly restricted by geographical conditions, so it is difficult to adapt measures to local conditions and facilitate transportation

[0004] To sum up, the limitations of technology and investment limit the development of decentralized sewage treatment facilities in remote areas and rural sewage treatment fields
