Description
Technical field
The utility model relates to the treatment facility of a kind of Treating Municipal Sewage and trade effluent.
Background technology
(Membrane Bioreactor MBR) as a kind of new and effective sewage disposal device, receives the concern of various countries to membrane bioreactor day by day.MBR is in the selection that becomes a kind of very attractive and competitive power aspect municipal effluent and Industrial Wastewater Treatment and the reuse, and is regarded as " best practical technology ".But it then is the main operating troubles of most of membrane process that film pollutes the membrane separating property decline that causes.
At present among the MBR and feed liquid--the composition of-mud mixed liquid comprises microflora, its meta-bolites and organic macromolecule, small molecules, dissolved substance and the solid particulate in the waste water handled.Each composition all can form film and pollute, but main from the microorganism flco greater than membrane pore size.This pollution major sedimentary is on the film surface, and obstruction and film internal surface all do not have obviously to pollute mostly in the hole.The film surface filter cake of suspension growth type MBR is thicker, and attached microbial is more, and it is rapid sedimentary sludge blanket that MBR is handled the high concentrated organic wastewater film outer surface, studies show that: film surface organic pollutant content is higher in MBR, and membrane resistance is had the greatest impact.This pollutent has caused the decline of membrane permeation flux, has contained the remove effect of hydraulic shear effect to pollution layer again.The bacterium and the microorganism that stick on the face also can directly or indirectly be degraded to film, make membrane structure become loose, have a strong impact on the separation performance of film, and have shortened the life-span of film greatly.
Current, known film pollutes the main method of cleaning that adopts and solves, because film device is immersed in the aeration tank, so on cleaning some particular requirements are arranged.At present the cleaning of film has physics to clean and two kinds of matting among the MBR.
(1) physics cleans: promptly remove pollutent with mechanical means from the film surface, mostly with water (being generally through liquid), the face of flowing through under the low pressure high flow rate sees through liquid side closure outlet valve, so that saturating film pressure is zero.Under the shear action that waterpower forms face, the face settling is washed.
Also used water or air enter the feed liquid side from crossing film through the side back-pressure under certain pressure, sweep away with the pollutent that will deposit and be blocked in the fenestra, and the feed liquid side keeps certain flow velocity, takes away these are washed the settling that gets off.Also there is pair immerseable flat sheet membrane to adopt the method for feed liquid side aeration (seeing through side closure suction water valve).In addition, also have, adopt the film piece is extracted out from bellows, face is washed also effective with high pressure water or brush with the flat film of immerseable.
(2) matting: immerseable MBR is had original position (In line) and displacement (Out line) two kinds of purging methods
1. original position is cleaned and displacement purging method and comparison
A. original position cleans as shown in Figure 1 that membrane module still is immersed in the aeration tank, cleans liquid medicine by seeing through the liquid pipeline, sees through film and enters the feed liquid side, and the organism of fenestra and film surface deposition is decomposed, and membrane resistance is descended.
B. after displacement dipping cleans as shown in Figure 2 membrane module hung out in the aerator tank, in soup, flood certain hour, rinse well to see through liquid again.
All there are some defectives in above purging method, as to the flat film of immerseable, adopts the film piece is extracted out from bellows, with high pressure water or brush face is washed and all can cause device to stop transport, and influence is produced.If the employing matting, matting will consume pharmaceutical chemicals on the one hand, can cause secondary pollution to water again, and matting can be brought inconvenience to production run on the other hand.But from recovering membrane flux, matting is absolutely necessary.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of cycle that prolongs online chemical agent flushing and off-line matting is provided, and may command matting frequency keeps the permeation rate of film and the vibration-type membrane bioreactor of rejection.
