Abstract

The invention belongs to the technical field of sewage treatment devices and in particular relates to an integrated membrane biological reaction system (MBR). The integrated membrane biological reaction system comprises an outer shell, an inner shell, a filtering system and a washing device, wherein the inner shell is arranged in the outer shell; a hollow part of the inner shell forms a first cavity; the first cavity is a membrane biochemical reaction tank; a second cavity is formed between the inner shell and the outer shell; the second cavity is a clean water tank; the filtering system is arranged on the inner shell; the inner shell is communicated with the outer shell through the filtering system; the filtering system is a stainless steel filtering screen; the washing device is arrangedin the first cavity; the washing device is used for washing the filtering system. The integrated membrane biological reaction system provided by the invention integrates a primary sedimentation tank,the biochemical reaction tank and a secondary sedimentation tank and a sewage treatment flow is simplified; the equipment has the advantages of investment saving, reliability in operation, simplicityin maintenance and low operation cost and troubles caused by membrane pollution and low pass in a traditional membrane bioreactor are completely solved; the integrated membrane biological reaction system brings a wider prospect for applying the MBR to middle-scale and small-scale sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment devices, in particular to an integrated membrane biological reaction system. Background technique [0002] Membrane Bioreactor (MBR) water treatment technology is a new type of water treatment technology that combines high-efficiency membrane separation technology and activated sludge method (T.Stephenson, S.Judd, B.Jefferson and K.Brindle, Membrane Bioreactors for Wastewater Treatment, IWA Publishing: London, 2000.). Due to the filtration effect of the membrane, microorganisms and sludge are completely trapped in the biological reaction system, which realizes the complete separation of hydraulic retention time and sludge age, makes the biological unit have a high sludge concentration, and improves its removal of organic matter Rate. [0003] Judging from the recent MBR research at home and abroad, most of the filter membranes of the filtration system are microfiltration membranes with ...
