Problems solved by technology

[0003] At present, in the actual application of anaerobic membrane bioreactor, membrane fouling is the main factor affecting its membrane separation effect and stable and efficient operation of equipment. However, due to the limitation of its own structure, anaerobic membrane bioreactor cannot be used and well The same aeration and purging method of the oxygen membrane bioreactor is used for membrane cleaning and dirt cleaning, which undoubtedly restricts the working efficiency and service life of the anaerobic membrane bioreactor, and has an adverse effect on its water treatment effect

Abstract

The invention discloses an anaerobic membrane bioreactor. The anaerobic membrane bioreactor comprises an anaerobic tank, a circulating pump, a suction pump, a backwashing tank and a backwashing pump,wherein the circulating pump and the suction pump are respectively connected with the anaerobic tank; the water inlet end of the backwashing pump is communicated with the backwashing tank; the water outlet end of the backwashing pump is connected with the anaerobic tank; a plurality of membrane components are successively arranged in parallel in the anaerobic tank; each membrane component comprises a support plate and a flat plate membrane which are parallel to each other. The membrane components of the anaerobic membrane bioreactor can be relatively efficiently and completely washed. The invention also discloses a using method of the anaerobic membrane bioreactor.

Description

technical field [0001] The invention relates to the technical field of sewage and wastewater treatment equipment, in particular to an anaerobic membrane bioreactor. The invention also relates to a method for using the anaerobic membrane bioreactor used for the anaerobic membrane bioreactor. Background technique [0002] MBR, Membrane Bio-Reactor (Membrane Bio-Reactor), is a new type of wastewater treatment system that combines membrane separation technology with biological treatment technology. more and more widely applied. Membrane bioreactors are usually divided into anaerobic membrane bioreactors and aerobic membrane bioreactors. Among them, anaerobic membrane bioreactors are a new type of water treatment technology that combines membrane separation technology with anaerobic biological treatment units. On the basis of retaining many advantages of anaerobic biological treatment technology, such as low investment, low energy consumption, recyclable biogas energy, high loa...
