Description

The integrated membrane-sludge method waste disposal plant

Technical field

The utility model relates to a kind of sewage disposal device, the particularly a kind of integrated membrane-sludge method waste disposal plant that can effectively remove organism and denitrogenation dephosphorizing.

Background technology

In the prior art, the method for sewage disposal has a lot, as chemical method, flocculation sedimentation, biological process etc., different sewage is had corresponding treatment process.Often adopt biological process to handle to containing organic sewage, utilize active sludge or microbial film in the equipment, carry out organism decomposition, nitrification and denitrification, remove organism and denitrogenation dephosphorizing, treatment process, equipment are complicated, total system is huge, and investment cost is big, working cost is high, the denitrogenation dephosphorizing effect is not ideal enough, and treating processes generally adopts separate equipment to finish.As the OCO waste disposal plant of producing by Denmark Puritek company, it integrates organism and eliminates and dephosphorization denitrogenation, effluent quality is good, index is stable, but its biological reaction tank and secondary sedimentation basins set up two places separately, the energy consumption that mud refluxes is bigger, cause total system too complicated, and floor space is big, working cost is high, energy consumption is high.A kind of organic sewage biochemical process integrated treatment unit that patent application 01206534.x provides, dispose of sewage by the inner bag separation, has the little advantage of low cost of manufacture and floor space, working cost is low, but because each functional zone is provided with undesirable, lack the hypoxia response district, and can't realize the water circulation between hypoxia response district and the aerobic reactor zone, influence the sewage disposal dephosphorization and denitrification effect.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved integrated membrane-sludge method waste disposal plant is provided, and reasonable disposition equipment reduces investment and working cost, improves sewage treatment capacity and efficient.

The purpose of this utility model can realize by following technical measures: this waste disposal plant has biological reaction tank, anaerobic reactor, settling tank, stir thruster and pipeline, biological reaction tank is columnar structured, anaerobic reactor is located at the middle part of biological reaction tank, be filled with carrier filler in the anaerobic reactor, anaerobic reactor one side is the hypoxia response district and the aerobic reactor zone of biological reaction tank, opposite side is the mixing zone of biological reaction tank, hypoxia response district and aerobic reactor zone adopt active sludge, between hypoxia response district and the aerobic reactor zone dividing plate is arranged, facing toward the hypoxia response district, the position of aerobic reactor zone is provided with the stirring thruster, the water outlet of anaerobic reactor is offered one side to the hypoxia response district, sewage inlet pipe is connected to the anaerobic reactor center, settling tank is located in the mixing zone of biological reaction tank, be in bend place, biological respinse pool side mixing zone, the settling tank bottom is arranged with cowling panel, and along the biological reaction tank radial array, cowling panel leaves the gap each other.

Also be provided with the rectification baffle plate at the settling tank two ends, across the mixing zone, rectification baffle plate lower end is lower than the settling tank bottom to the rectification baffle plate along settling tank two ends sidewall.

Sewage enters anaerobic reactor from sewage induction pipe, the filler of flowing through makes sewage fully contact with filler and is hydrolyzed, sewage after anaerobic reactor is handled flows to the hypoxia response district of biological reaction tank, stirring under the angle of rake effect, mixing zone in the pond makes mud mixture repeated multiple times circulation between hypoxia response district, aerobic reactor zone, flow into settling tank through cowling panel and carry out precipitate and separate and discharge, and uses that directly reflux of part active sludge, excess sludge can discharge by discharge outlet is set.

The utility model is reasonable in design; anaerobic reactor, settling tank and combined integratedization of biological reaction tank; each functional zone effect obviously; the active sludge use that can directly reflux; settling tank bottom and two ends sidewall have cowling panel; can alleviate settling tank current race conditio; raising equipment is to the processing power and the efficient of sewage, effectively removes the pollutent such as organic, phosphorus, nitrogen of sewage, helps ecological environmental protection; it is simple in structure; floor space is little, and initial cost is low, and working cost is low; adaptability is strong, is the environmental protection equipment of Nover practical.

Embodiment

With reference to Fig. 1, Fig. 2, the biological reaction tank of this waste disposal plant [1] is a circular cylinder body, anaerobic reactor [8] places in the middle of the biological reaction tank [1], in the anaerobic reactor [8] is the anaerobic reaction district, be filled with carrier filler, filler can be fillers such as three-dimensional ripple medium-soft plastelast, adopt multilayer concentric cylinder baffling type anaerobic reactor effect better, anaerobic reactor [8] one sides are oxygen-starved area [9], aerobic zone [10], opposite side is mixing zone [3], oxygen-starved area [9], aerobic zone [10] is separated by dividing plate [11], in active sludge is housed, facing toward hypoxia response district [9], the position of aerobic reactor zone [10] is provided with stirs thruster [2], water can be in hypoxia response district [9], aerobic reactor zone [10] and lining, mixing zone [3] circulate, the water outlet of anaerobic reactor [7] is opened to hypoxia response district [8], sewage induction pipe is connected to anaerobic reactor [8] center, settling tank [4] is located in biological reaction tank [1] mixing zone [3], build along the biological respinse pool side, at mixing zone bend place, be circular arc, in the settling tank bottom cowling panel [5] is housed, cowling panel [5] is an inverted v-shaped, its shape is seen Fig. 3, along the biological reaction tank radial array, cowling panel [5] leaves the gap each other, also is provided with rectification baffle plate [7] at the settling tank two ends, be cavernous structure, across mixing zone [3], the lower end is lower than settling tank [4] bottom, is provided with water outlet [6] in settling tank [4] lining along settling tank two ends sidewall, water outlet [6] can efflux the treating water after the clarification, and excess sludge can be by being provided with discharge outlet [12] discharging.

Sewage enters the anaerobic reaction district by sewage induction pipe through the anaerobic reactor center, and suspended substance and macromolecule organic at this hydrolysis reaction take place; Sewage is in aerobic reactor zone, and organism carries out aerobic decomposition at this, and ammonia nitrogen is nitrated to be nitrate; In the hypoxia response district, the nitrate radical that aerobic reactor zone produces carries out denitrification at the organic carbon that this utilizes the hydrolysis water outlet to provide, and nitrate radical is converted into nitrogen, thereby eliminates the influence of ammonia nitrogen to body eutrophication; The mixing zone can make the mud mixture from aerobic reactor zone and hypoxia response district carry out thorough mixing, can realize under the angle of rake effect that mud mixture in aerobic reactor zone, the region repeated repeatedly circulation of hypoxia response, finishes the elimination of organic pollutant in the sewage and nitrated, the denitrification of nitrogenous compound stirring; The gap of mud mixture between cowling panel enters settling tank, carries out mud-water separation in settling tank.
