Abstract

The invention discloses a sponge-assisted anaerobic granular sludge membrane bioreactor, which comprises a reactor body, wherein the lower portion in the reactor body is filled with a granular sludge bed, porous sponges attached with microorganisms are uniformly embedded in the granular sludge bed, a hollow fiber membrane is mounted on the upper side of a clear liquid part, and a water pipe is connected between a clear water tank and the hollow fiber membrane, and is serially connected with a water pump. Compared with a traditional anaerobic granular sludge membrane bioreactor, the sponge-assisted anaerobic granular sludge membrane bioreactor has a better organic matter and nutrient substance removal effect and higher methane yield, wherein a sludge bed is formed by filling a plurality of porous sponges, anaerobic microorganisms grow on the porous sponges in an attached mode, and the sponge-assisted anaerobic granular sludge membrane bioreactor is used for purifying domestic sewage. The sponge-assisted anaerobic granular sludge membrane bioreactor has the advantages that the removal rate of organic matters and nutrient substances is better, the characteristics of granular sludge are better, membrane pollution control is more effective, and the yield of methane is increased.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage purification treatment devices, in particular to a sponge-assisted anaerobic granular sludge membrane bioreactor. Background technique [0002] Anaerobic biological treatment technology is an efficient sewage treatment method in which organic matter in sewage is decomposed, metabolized, and digested by anaerobic bacteria under anaerobic conditions, so that the content of organic matter in sewage is greatly reduced and biogas is generated at the same time. As an important form of biological treatment, anaerobic treatment is gradually developing a series of new anaerobic treatment processes and structures, gradually overcoming the shortcomings of traditional anaerobic processes, and has made great progress in theory and practice. Utilizing the metabolic characteristics of anaerobic microorganisms, the reduced organic matter in the sewage is used as the hydrogen acceptor under the condition o...
