Description

Adopt the MBR film group device of mechanical vibration scale removal
Technical field
The utility model relates to sewage treatment area, and specifically, the utility model relates to a kind of MBR film group device that adopts the mechanical vibration scale removal.
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.
Like Fig. 1, shown in 2, MBR is that the core component of membrane bioreactor is a film group device.Tens of membrane modules are installed on each film group device.Membrane module is made up of with bellows 2 the hollow-fibre membrane silk 1 that the surface is covered with micropore.Tens membrane modules as shown in Figure 1 are installed on the stainless steel stent, become film group device.
Traditional M BR film group device adopts the mode of bottom aeration to remove the dirt on film silk surface.See Fig. 2; Film group device is placed in the sewage lagoon, and pressurized gas flows out from the aperture of boring aeration pipe 3, forms bubble 4, and bubble rises, and drives current and rises, and forms the air water mixed flow, and this fluid ratio heavy and light is unsettled turbulent flow.When gas, water flow through film silk 1, the dirt that the film silk is surperficial washed away.
Owing to contain a large amount of bacterium excretory extracellular polymerics in the sewage, this organism is thickness very, attaches easily on the surface of hollow-fibre membrane silk, stops up the micropore on film silk 1 surface.And this polymeric adhesive is big, and the air water flushing is difficult to cause the film silk frequently to need matting its removing.Influence the normal operation of Sewage Plant.
