Description
Technical field
The utility model relates to sewage treatment area, and specifically, the utility model relates to a kind of film silk unit of novel immersion film group device.
Background technology
China's water resources owning amount per capita is merely 2250m
3/ people. year, 1/4 of not enough world average level.In more than 600 city of China, have 300 surplus a urban water shortage, surplus wherein the city of severe water shortage has 100, year nearly 6,000,000,000 m of water deficit
3, cause financial loss about 2,000 hundred million yuan because of lack of water every year.North China's water resources ownership per capita has only 250-480m
3/ people. year, being lower than 1/5 of national per capita share, these geographic all cities nearly all face water shortage problem.Therefore reusing sewage is one of important measures of alleviating North China Plain water crisis.
Membrane bioreactor (Membrane Bioreactor is called for short MBR) is one of novel waste water technology of membrane separation technique and biotechnology combination, also claims the film separated activated sludge method.The efficient cutoff performance that it utilizes membrane separation assemblies carries out solid-liquid separation, has effectively reached the purpose of mud-water separation.The efficient crown_interception of film can the effectively catching nitrifier, and it is trapped in the bio-reactor fully, makes nitration reaction smooth, effectively removes ammonia nitrogen, avoids the loss of mud.Can hold back simultaneously the larger molecular organics that for the moment is difficult to degrade, prolong the residence time of these organism, make it to be decomposed to greatest extent at reactor drum.Because the high filtering precision of film, thereby guaranteed the as clear as crystal second pond that saves of water outlet.After using the MBR technology, compare with traditional bioremediation, principal pollutant (COD) clearance can reach 90%, produces water suspension and is bordering on zero with turbidity, and water quality is good and stablize, can direct reuse, realized sewage recycling.Have that biochemical efficiency height, anti-load impact ability are strong, stable effluent quality, floor space is little, sludge discharging period is long, be prone to realize advantages such as automatic control, is one of the most promising wastewater treatment new technology at present.Membrane Bio-reactor Technology is mainly used in municipal sewage treatment/crude sewage and handles and utilization again, fields such as high concentrated organic wastewater processing.
The major equipment of MBR is a film group device; A large amount of hollow fiber ultrafiltration membrane is installed on the film group device; About the general 2mm of ultra-filtration membrane external diameter, about internal diameter 1mm, the ultra-filtration membrane surface is covered with 0.04 micron aperture; See tubular fibre film silk from the outside just as the fine plastics silk of a rule, tubular fibre is arranged in parallel on the film group device.When operation, film group device is placed in the sewage, clear water is inner to the film silk through micropore permeation from the outside of film silk, and mud is blocked in the outside of film silk.With water pump clear water is drawn into the clean water basin from film group device again.High density mixed solution in the membrane biological reaction pond is through membrane sepn, and pollutent is left in the reaction tank with other mikrobe, and treated water then passes through negative pressure-pumping, qualified discharge.
The MBR treatment facility and the treating processes that specify prior art in conjunction with accompanying drawing 1,2 are following, as shown in Figure 1, and the major parts of MBR is a membrane module 1, and it is made up of the film silk 2 and the fixing bellows 3 of film silk.Film silk 2 is covered with the hollow-fibre membrane of micropore for the surface.The two ends of film silk 2 adopt epoxy resin glue to be poured on the plastics bellows 3, and through the cutting machine cutting, the film silk endoporus that makes epoxy resin build the body end face exposes; Film silk 2 endoporus partly are communicated with the internal cavity of bellows 3; Form the water outlet of bellows 3, bellows 3 connects one with numerous film silks 2 up and down, constitutes a membrane module 1; Several membrane modules 1 are arranged side by side, and constitute a film group device 4.
The membrane biological reaction pond of prior art is as shown in Figure 2, comprises film group device 4 is put in the sewage biochemistry pool 5, and sewage is put into biochemical sewage lagoon 5 by water inlet pipe 6.During operation, start suction pump 7, because vacuum action, the clear water in the sewage 5 is gone into the endoporus of tubular fibre from the surface seepage of film silk 2, flows into bellows 3, the fresh water pipeline 8 through being communicated with bellows 3 water outlets again, suction pump 7 inflow clean water basin.Pollutants in sewage matter is trapped within outside the surface of film silk 2, realizes mud-water separation.Because in aspiration procedure, constantly in film silk 2 cumulative, flow resistance continues to increase mud, need carry out aeration to film group device 4, and film silk 2 is constantly shaken, remove film silk 2 surperficial mud, reduce water and flow through membrane resistance, recover the flux of current.Aeration be through blower fan 9, airduct 10, boring aeration pipe 11 to the bottom of film group device 4 injecting compressed air, air flows out from aeration tube 11, forms bubble 12; Because the rising of bubble; Drive on the current direction and flow, in the outside of film group device 3, the current direction current downflow; Get into the bottom of film group device, form circulation (curved arrow illustrates in the accompanying drawing 2).The sludge concentration of MBR biochemistry pool 5 is high, and mud is very fast at the accumulating rate on film surface, therefore needs the HS aeration could the mud on film silk 2 surfaces be shaked off, to guarantee normally operation of MBR film group device 4.
Owing to strengthen aeration rate to strengthen scouring intensity to the film silk, need to open gas blower more, obviously this can directly increase processing cost and energy consumption.The working cost of sewage work is risen, and this problem becomes the major obstacle of MBR new technology spread.Solve the breakthrough that this difficult problem will be a sewage disposal technology, energy-conserving and environment-protective and minimizing carbon emission are had crucial meaning.
The utility model mainly is in the prior art, the film silk top deposition that film silk two ends fixed MBR film group device occurs, and film silk top is stressed bigger, and the film silk is tired, and defectives such as easy decortication are made improvement.
