Description
Technical field
The present invention relates to sewage treatment area, the device and method of aerobic activated sludge quick particleization in particularly a kind of membrane bioreactor.
Background technology
Bio-reactor is to utilize biological catalyst that the equipment of good reaction environment is provided for cell cultures, enzyme reaction, WWT; Bio-reactor is the key equipment in the bioprocesses, and its structure, operating method and operational condition have very big influence to the quality of biological technology products and the energy consumption of transformation efficiency and bio-reactor.Membrane bioreactor is an emerging sewage disposal technology that combines membrane technique with the biochemical reaction technology, is one of the most promising sewage disposal technology at present.In operational process; Membrane bioreactor is through keeping higher living weight; Can realize that the organism in the sewage degrades rapidly; Simultaneously because film has stalling characteristic efficiently; With adopting gravity settling separation is that main traditional activated sludge process sewage treatment process is compared, and membrane bioreactor has outstanding advantages such as effluent quality is good, compact construction, excess sludge production is few, volumetric loading is high, the operation operation is simple, therefore over past ten years membrane bioreactor in the range of application of sewage treatment area in continuous expansion; And because the increase of membrane bioreactor scale can significantly reduce its process cost again, thereby improved the competitive capacity of membrane bioreactor at sewage treatment area, make it have bright development prospect.
Traditional membrane bioreactor uses active sludge; Because membrane bioreactor in operational process, must keep certain film driving pressure, a large amount of particulates that at this moment exist in the system, fine colloidal particle; Especially a large amount of mud flcos; Can be on the film surface or fenestra internal adsorption, deposition, cause membrane pore size to diminish gradually or stop up, cause membrane flux and stalling characteristic to reduce significantly.For being in operation, membrane bioreactor obtains stable membrane flux; Traditional membrane bioreactor general mode that improves aeration intensity that adopts in operational process is improved this situation; This method makes that the ability loss-rate traditional biological treatment process of membrane bioreactor is obviously higher; Lot of experiments result shows that aeration energy consumption accounts for 80～90% of membrane bioreactor operation total energy consumption; Therefore how to reduce the aeration rate in the membrane bioreactor operational process, the effectively film of controlling diaphragm bio-reactor pollution again is the important subject of membrane bioreactor simultaneously.

(2) making COD concentration is that 250～600 mg/L, ammonia nitrogen concentration are that 18～73mg/L, pH are 6.86～7.4 the said membrane bioreactor of the continuous entering of sewage, and membrane filtration water outlet, aeration and supernatant is discharged carry out batch operation respectively;
(3) said membrane bioreactor operation is after 7～14 days, and the aerobic activated sludge prilling in it has generated the aerobic activated sludge particle, and said membrane bioreactor promptly becomes prilling aerobic activated sludge internal-circulation type membrane bioreactor.
3. membrane bioreactor as claimed in claim 2 is characterized in that, said membrane filtration water outlet batch operation is membrane filtration water outlet 6～10 minutes, stops 6～8 minutes; Said aeration batch operation is aeration 100～172 minutes, stops 5～8 minutes; The batch operation that said supernatant is discharged moves 3～4 minutes for stopping 60～177 minutes.
4. the method for preparing the oxygen activity mud granule as claimed in claim 2; It is characterized in that; Aerobic activated sludge particulate concentration is 3000～10000 mg/L in the said prilling aerobic activated sludge internal-circulation type membrane bioreactor; Median size is 400～1200 microns, and the aerobic activated sludge particle accounts for more than 90% of mud total amount in the said prilling aerobic activated sludge internal-circulation type membrane bioreactor.
