Abstract

The invention relates to a sewage treatment device, and discloses a membrane bioreactor with a duplex decoupling function. The membrane bioreactor comprises at least two sewage treatment units and a membrane treatment unit. A diversion plate (8) is arranged in a first shell (1). The two sides of the diversion plate (8) are each provided with a biodegradable face plate (6). An aeration pipeline (2) is arranged at the bottom of the first shell (1). The membrane treatment unit comprises a second shell (13) and a membrane assembly (11). A staggered aeration unit (15) and an inclined plate reaction unit (16) are sequentially arranged below the membrane assembly (11) from top to bottom. The bottom of the membrane treatment unit and the bottoms of the sewage treatment units are each connected with a sludge setting tank (3). A pneumatic sludge stirring device (5) is arranged in each sludge setting tank (3). A brand-new concept is provided for improving the efficiency of the integrated membrane bioreactor, lowering the membrane separation running energy consumption, and prolonging the service life of the membrane assembly.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a membrane bioreactor. Background technique [0002] While the membrane bioreactor effectively integrates the dual functions of microbial decomposition and high-efficiency membrane separation, it also inevitably brings about the problem of membrane fouling. A lot of practice shows that membrane fouling has become a bottleneck problem that must be overcome in the development of this new process. From the analysis of its treatment process and characteristics, membrane fouling is the adsorption and deposition of particles, colloidal particles or solute macromolecules in contact with the membrane on the surface of the membrane and in the pores of the membrane through physical, chemical, biological and mechanical effects. And the accumulation of microorganisms on the water interface of the membrane causes the effective pore size of the membrane to become smaller or even blocked, resulting...
