Abstract

The invention discloses an anaerobic membrane bioreactor for effectively treating kitchen waste water and a treatment method using the same. The anaerobic membrane bioreactor orderly comprises an anaerobic tank, a circulating pump, a water inlet pump, a water inlet tank and a water outlet tank from left to right. The circulating pump and the water inlet pump are respectively connected to the anaerobic tank. The water inlet tank is connected to the water inlet pump. The treatment method comprises adding sludge into the anaerobic membrane bioreactor, setting different sludge staying time, mixing kitchen waste water and a film concentrated solution, feeding the mixture into an anaerobic jar through a water distribution pipe, discharging the decomposing biogas through a water-sealed tank, feeding undecomposed mixed solution into the circulating pump and a membrane module, mixing the undecomposed mixed solution and kitchen waste water fed by the water inlet pump, feeding the mixed solution into the anaerobic jar through a water distribution pipe, and carrying out circulation. The bioreactor and method can eliminate accumulation of colloidal state and dissolved macromolecule organic matters through reasonable control of the sludge residence time, reduce a Ca<2+> accumulation concentration, and reduces a degree of calcification of the sludge. The anaerobic membrane bioreactor has optimal effects of treating kitchen waste water.

Description

technical field [0001] The invention relates to an anaerobic membrane bioreactor, in particular to an anaerobic membrane bioreactor for effectively treating kitchen waste water and a treatment method thereof. Background technique [0002] The development and application of anaerobic membrane bioreactor is a research hotspot in recent years. Based on the complete interception of microorganisms by the membrane module, the anaerobic membrane bioreactor can realize the effective separation of sludge retention time and hydraulic retention time. Because of this, the anaerobic membrane bioreactor has the advantages of high biomass, high conversion rate of organic matter, strong impact load resistance and good effluent quality. However, most of the anaerobic membrane bioreactor equipment is only used to treat organic wastewater. The anaerobic membrane bioreactor in the present invention can effectively treat domestic and kitchen wastewater. Contents of the invention [0003] Th...
