Abstract

The invention relates to a fast culture method of aerobic granular sludge in a film bioreactor, which pertains to the technical field of wastewater treatment. The method is different from the batch culture method which is widely adopted currently, but adopts continuous water inlet and outlet and is capable of shortening the culture time of the aerobic granular sludge; therefore, the shortest period to obtain the aerobic granular sludge is 5 days.

Description

The fast culture process of aerobic particle mud in the membrane bioreactor
Technical field
The fast culture process of aerobic particle mud belongs to technical field of waste water processing in the membrane bioreactor.Can shorten the incubation time of aerobic particle mud greatly.
Background technology
The sewage aerobic biological treatment is topmost method of wastewater treatment and the most frequently used means, be widely used in the purifying treatment engineering of municipal effluent and trade effluent, these technology are at aspects such as design theory, actual motion management, the experience that comparative maturity has all been arranged, but still there is major defect in these technology at aspects such as mass-transfer efficiency, operational administrative, operating load and energy consumptions, and effluent quality also can't reach the higher regional emission standard of water quality requirement.
Aerobic particle mud is to set up on the basis of anaerobic grain sludge research as a kind of cell self immobilization particle technology.Because granule sludge has fabulous settling property sludge retention time and hydraulic detention time is separated, the active biomass that can keep high density, and can improve gas, liquid, solid three phase separation effect, be beneficial to solid-liquid separation and guarantee effluent quality, so this technology more and more comes into one's own.
Membrane bioreactor is the high-efficiency activated mud waste water treatment reactor of just coming out in recent years.After treatment, water sees through the separatory membrane discharging to sewage in activated sludge reactor, and mud (microorganism) is trapped.The mud of holding back still is retained in the reactor, and high-quality water outlet can be used in greening irrigation, flushing lavatory and agricultural irrigation etc. again, has realized the resource utilization of waste water.Compare with traditional activated sludge process, membrane bioreactor in the characteristics aspect the processing sanitary sewage is: (1) contaminant removal efficiency height, treat effluent water quality is good.Not only to suspended solids and organic removal efficient height, and can remove bacterium and virus etc., but the water outlet direct reuse; (2) microorganism is trapped in the bio-reactor fully, the separating fully of realization response device hydraulic detention time and sludge age; (3) the microorganism concn height in the bio-reactor, device processing volume load is big, and sludge yield is low, and equipment takes up an area of few.
Membrane module in the membrane bioreactor easily pollutes, stops up, and it is a major reason of restriction membrane bioreactor widespread use that regular cleaning, replacing cause running cost to rise.Applicant's invention combines aerobic particle mud technology and membrane Bio-reactor Technology, has developed a kind of novel aerobic granule sludge membrane bioreactor system, has alleviated the film pollution greatly, has reduced running cost.But the cultivation of aerobic particle mud in the membrane bioreactor, the time is long, difficult control.
Summary of the invention
The fast culture process that the purpose of this invention is to provide aerobic particle mud in the membrane bioreactor.It is seed sludge that method of the present invention adopts the mixture of anaerobic grain sludge or aerobic particle mud and active sludge, and aerobic cultivation forms aerobic particle mud in aerobic granule sludge membrane bioreactor system (accompanying drawing 1, patent applied for).
Specifically at aerobic granule sludge membrane bioreactor system (accompanying drawing 1, patent applied for) it is good to insert settling property in, and mud is rounded or oval, and particle diameter is the anaerobic grain sludge of 0.5-1.5mm, seed sludge concentration is MLSS3-30g/L, and the VSS/SS ratio of mud is 0.5-0.8.The COD that regulates water inlet is 300-1000mg/L, NH 3-N is 10-100mg/L, and P is 3-15mg/L, the control aeration rate, and making the surface gas flow velocity is 0.002-0.007m/s, 5-20 days acquisition aerobic particle muds are cultivated in water inlet and get rid of the mud in small, broken bits and the water of settleability difference by water port continuously.Perhaps at aerobic granule sludge membrane bioreactor system (accompanying drawing 1, patent applied for) inserts the mixture of aerobic particle mud and active sludge in, the aerobic particle mud settling property is good, mud is rounded or oval, particle diameter is 1-2.5mm's, the ratio of granule sludge and active sludge is 1: 20-1: 4, and seed sludge concentration is MLSS 3-30g/L, the VSS/SS ratio of mud is 0.5-0.8.The COD that regulates water inlet is 300-1000mg/L, NH3-N is 10-100mg/L, P is 3-15mg/L, the control aeration rate, making the surface gas flow velocity is 0.002-0.007m/s, continuously water inlet and water outlet, and get rid of the mud in small, broken bits and the water of settleability difference by water port, cultivate 5-20 days acquisition aerobic particle muds.

Embodiment
Give further detailed explanation below by embodiment to the present invention.
The granule sludge of embodiment 1:GMBR is cultivated
Add anaerobic grain sludge in reactor, pH is between 7.0~8.0 in control, and system COD volumetric loading is at 0.5~1.0kg/m 3.d change between, the control aeration rate, left and right sides anaerobic grain sludge fragmentation in 1 day was that nucleus is grown up gradually and become to have the polymer of relative compact structure with the dirty chip of anaerobic grain after 2-3 days, aerobic particle mud engendered in 5-8 days.By control aeration rate and spoil disposal, the relatively poor floc sludge of settling property is constantly washed out on this basis, in the reactor based on granule sludge.Interruption is got rid of mud in small, broken bits from water port.
