Abstract
The invention relates to an MBBR (moving bed bio-film reactor) reaction system with an enhanced denitrification function. The system comprises an MBBR reactor and a sedimentation tank; and the MBBR reactor comprises an MBBR reactor main body, the interior of the MBBR reactor main body is divided into anoxic reaction zones and an aerobic reaction zone through baffles, the upper part of the aerobicreaction zone communicates with the upper parts of the anoxic reaction zones through overflow openings, the bottoms of the anoxic reaction zones communicate with the bottom of the aerobic reaction zone through aerobic zone-anoxic zone communication openings, an MBBR filler is arranged in the aerobic reaction zone, an MBBR reactor water discharging pipeline is arranged at the upper part of the aerobic reaction zone, a perforated water distribution pipe is arranged at the lower part of the aerobic reaction zone, and the perforated water distribution pipe is sequentially connected with a jet device, a jet pump and a reactor water inlet pipeline. According to the system provided by the invention, after sewage comes out from the perforated water distribution pipe, the sewage has a certain rising flow velocity, and in the rising process of a water flow, rising, swirling and turning of the MBBR filler in the aerobic zone are driven, so that the amount of a bio-film on the filler can be effectively increased, and the treatment capacity can be improved.
Description
technical field [0001] The invention relates to an MBBR reaction system with enhanced denitrification function, which belongs to the field of sewage treatment equipment. Background technique [0002] MBBR (Moving Bed Bio-film Reactor, Chinese name: moving bed biofilm reactor) process is a sewage treatment process jointly developed by Kaldnes Mijecpteknogi Company of Norway and SINTEF Research Institute, which absorbs the traditional fluidized bed and biological contact oxidation Advantages of the two techniques. The sewage continuously passes through the MBBR reactor, and the suspended filler in it gradually forms a biofilm on the inner and outer surfaces of the filler, and the sewage is purified through the action of microorganisms on the biofilm. The filler moves freely under the action of the swirling and turning of the mixed liquid in the reactor. [0003] Compared with the conventional activated sludge reactor, the pollutant removal load of the MBBR reactor is higher,...
