Description
Technical field
The utility model is related to filtration film device technical fields, and in particular to a kind of plate filtering membrane equipment.
Background technology
For environmental protection, it usually needs be then exhausted from after being filtered processing to resident living sewage and trade effluent.It is existing
The treatment process of some sewage includes the biochemical process based on activated sludge and the membrane biological reaction method based on membrane bioreactor.
Biochemical process based on activated sludge is a kind of this traditional treatment process, and there are effluent qualities, and poor, treatment facility takes up an area face
The defects of product is big, sludge yield is big, inefficiency and realization technology stability control difficulty are big.Membrane biological reaction method divides film
It is organically combined from technology and traditional wastewater biological treatment, it replaces two in traditional activated sludge process to sink with membrane separation technique
Activated sludge and larger molecular organics are retained, can not only effectively realize separation of solid and liquid, and substantially increase in reactor by pond
The concentration of activated sludge to greatly improve effluent quality, and reduces the volume of entire reactor.
The membrane material that existing membrane bioreactor uses contains organic film and inoranic membrane both materials.Using organic film
Membrane bioreactor be made of by coating organic filter membrane material outside cloth or fibre pipe.Since organic filter film is mostly
Petrochemical industry material or plastics are made, and carrier cloth or fibre pipe equal strength are poor, the intensity difference of such membrane bioreactor, film group
Part is easily broken off, and especially hollow-fibre membrane is susceptible to film wire fracture.And it is difficult in a short time that it is general, which fracture occur, for film wire
It is found, in the case, membrane bioreactor can be lowered the processing effect of sewage in very big intensity.If not processed
Good sewage enters rivers, then can cause serious pollution condition.In addition, in the case where finding that membrane module is broken, it is right
Membrane module, which replace, needs sewage disposal system out of service.It is special since the quantities and nonrecurring charge of changing film are all very big
It is not that is changed by film and is led to the problem of with regard to increasingly complex for fairly large membrane bioreactor engineering, the adverse effect model of generation
Enclose bigger.Therefore, using the membrane bioreactor of organic film, film strength is poor, and service life is short to have become current obstruction film
Bioreactor is extensive and the important restrictive factor and significant technology issues of popularization and application.
For the membrane bioreactor using inoranic membrane, metal film is fixed in a braced frame by general city.Metal
Good, acid and alkali-resistance, high temperature resistant, organic solvent-resistant, mechanical strength are big with chemical stability for film, long lifespan, can backwash, is anti-micro-
The advantages that ability of biology is strong.However, since metal film quality is heavier, this can make such membrane bioreactor heavier mass,
Meanwhile to ensure that reliable supporting role, braced frame needs are made of metal material, this makes such membrane bioreactor matter
Amount aggravates.Further, due to that metal film can be made to shake during carrying out film reaction, this makes to such reactor
The Structural strength calls of braced frame further increase, metal material needed for braced frame is more, and which in turns increases this
The quality of class membrane bioreactor.

Layer fits closely；Organic water penetration support body layer and filter layer are respectively the micropore formed by the porous material containing silica sand
Structure, wherein the micro-pore diameter of organic water penetration support body layer is more than the micro-pore diameter of filter layer, and the cavity is in cylinder
Shape, the top and the bottom are in wavy, and the lowest point at the top and the wave crest of the bottom are oppositely arranged.
Further, organic water penetration support body layer is multilayer, and from described organic far from the filter layer
The micro-pore diameter of aqueous support body layer to the organic water penetration support body layer for being bonded the filter layer is gradually reduced.
Further, the thickness of the filter layer is 0.2-3mm, and the overall thickness of organic water penetration support body layer is
10-45mm。
Further, the top and the bottom are in wavy, and the wave of the lowest point at the top and the bottom

On the basis of common knowledge of the art, above-mentioned each optimum condition can be combined arbitrarily to get each preferable reality of the present invention
Example.
In the present apparatus, filter membrane is supported by braced frame, and filter membrane is arranged to by organic water penetration support body layer and filtering
Layer composition, when carrying out sewage disposal, sewage passes through organic water permeable filter layer, organic water penetration support body layer, support frame successively
Frame.Compared with prior art, the utility model has the advantage that：Since organic water penetration support body layer can be organic mistake
Filtering layer provides certain supporting role, thus is required to drop significantly to the structural strength of braced frame in filtration film device
Low, braced frame can be made of the rigid plastics of lightweight, and the weight of filtration film device can mitigate significantly；And due to water penetration branch
The case where supporting role of support body layer, organic water permeable filter layer is broken without worry.
