Abstract
The invention provides a self-forming dynamic membrane bioreactor using aerobic granule sludge. The self-forming dynamic membrane bioreactor is characterized in that the self-forming dynamic membrane bioreactor comprises a reactor, wherein the top of the reactor is connected with a water inlet tank through a measuring pump, two baffle plates are arranged in the reactor in parallel, a porous supporting plate is arranged in the lower position between the two baffle plates, one end of an aerator pipe is arranged between the two baffle plates, the other end of the aerator pipe is connected with a draught fan, a membrane assembly is arranged outside the two baffle plates, the membrane assembly is connected with a water outlet pipe, a sludge sedimentation basin is arranged at the bottom of the reactor, and an overflow pipe is arranged at the upper portion of the reactor. According to the self-forming dynamic membrane bioreactor, the defects in the prior art are overcome, the technology which combines the self-forming dynamic membrane bioreactor with the aerobic granule sludge is provided, the self-forming dynamic membrane bioreactor has the advantages of being easy to operate, capable of bearing high organic loads and good and stable in processing effect, and the pollution condition of a self-forming dynamic membrane is greatly reduced.
Description
technical field [0001] The invention relates to an autogenous dynamic membrane bioreactor using aerobic granular sludge, belonging to the technical field of sewage treatment. Background technique [0002] At present, aerobic granular sludge (Aerobic Granular Sludge, AGS) is a granular activated sludge formed by microorganisms through self-coagulation under specific environmental conditions. The microorganisms contained in it are all common species. Depending on the action, a stable and dense structure is formed. As we all know, aerobic biological treatment process is far more common than anaerobic biological treatment process in sewage treatment, but the research on aerobic granular sludge lags behind anaerobic granular sludge obviously. The goodness of anaerobic granular sludge has aroused researchers' interest in cultivating granular sludge under aerobic conditions. People's research on aerobic granular sludge is based on anaerobic granular sludge. [0003] In 1991, Mish...
