Description

The proving installation of the special-purpose filter membrane of film-bioreactor
Technical field
The utility model relates to the proving installation of filter membrane, the proving installation of the special-purpose filter membrane of particularly a kind of film-bioreactor.
Background technology
(membrane bioreactor, MBR) technology is the new technology of wastewater treatment and water resource reuse aspect in the environmental engineering to film-bioreactor, is that a kind of membrane separation technique combines with microbiology, biological chemistry and carries out the new technology of wastewater treatment.It is a kind of novel method for treating water that the high performance membrane separating technology is combined with traditional activated sludge process, it is compared with traditional biochemical sewage disposal technology, has good effect of separating solid from liquid, the biochemical efficiency height, effluent quality is excellent, equipment is concentrated, floor area is little, the sludge concentration height, sludge loading is low, be convenient to advantages such as management and automatic control, substantially solved the sludge bulking that traditional activated sludge process exists, the problem that the water reuse required during the effluent quality that factors such as sludge concentration is low cause did not reach, in middle water reuse and wastewater treatment, have broad application prospects, can be widely used in the processing of municipal wastewater and multiple organic industrial sewage.
Film-bioreactor (MBR) mainly is made up of film separation system and bio-reactor, and film separation system is the main device of this new technology, and filter membrane is the core parts of film separation system.
At present, the MBR membrane module can be divided into hollow fiber film assembly and flat sheet membrane (flat sheet membrane) assembly.Gunder (the Gunter B of Germany, Krauth K.Replancement of final clarification bymembrane separation-Result with plate and hollow fibber modules[A] .IAWQ19th Biennial International Conference Preprint[C], Book 4,21-26 June1998-Vancouver, Canada.144~151) etc. the people finds by the flat sheet membrane of contrast Kubota company and the hollow-fibre membrane of Zenon company: under identical water quality and working pressure condition, effluent quality does not have evident difference, and the membrane flux of flat sheet membrane elementary membrane area is higher than hollow-fibre membrane, shows lower membrane resistance characteristic.Therefore, the flat sheet membrane component application is in membrane bioreactor, and result of use and application prospect are more good.Emphasis development both at home and abroad, exploitation in recent years has that flux is big, intensity is high, acid and alkali-resistance and microbiological corrosion, anti-pollution, ultrafiltration cheaply or microfiltration membranes.
But the plain film formula filter membrane of membrane bioreactor special use does not still have a kind of desirable laboratory evaluation method at present.Because the filter membrane component of built-in membrane bioreactor adopts low-voltage vacuum suction operation principle, therefore the test and evaluation to the special-purpose filter membrane performance of MBR also should carry out under similar low-pressure suction condition.And the laboratory evaluation device of current general ultra filtration membrane performance all adopts the compression type principle of work.Microfiltration membranes then mainly adopts the method for measuring the aperture.
The laboratory evaluation device of general compression type ultra filtration membrane performance has several styles.Fig. 1 is the cross-section structure that flat membrane ultrafiltration is estimated the pond.For the ease of observing, the pressurized cylinder is a material with organic glass generally, estimates the rotor that the pond is provided with electromagnetic agitation, or with the paddle of motor drive.
It is the thin channel type that the pond is estimated in the ultrafiltration of another kind of flat sheet membrane, and flow channel depth is 1.5~2.0mm.Because liquid linear velocity height in the thin channel, the concentration polarization that has alleviated film greatly improves the penetration speed of film.Fig. 2 is the flow circuit diagram that the pond is estimated in the thin channel type ultrafiltration of U.S. Amicon company.
By Fig. 1,2 as can be known, though the laboratory evaluation device of ultra filtration membrane performance has adopted the structure of stirring apparatus or thin channel, to alleviate the concentration polarization on film surface, but all be by pressurization makes it pass through ultra filtration membrane to liquid, and pressure is higher, usually to reach more than the 0.1MPa, different with the mode of actual MBR operation, can not imitate truth the special-purpose ultra filtration membrane of membrane bioreactor is evaluated and tested.
Secondly, the specification performance of commercial miillpore filter all characterizes with average pore size, and its determination techniques mainly contains: electron microscope method, mercury intrusion method, bubble platen press, gas flowrate method, known particle are by method etc.Yet single performance that still is not enough to the special-purpose filter membrane of complete characterization of membrane bio-reactor with average pore size, permeability rate, permeability rate and the rejection to contain standard particle solution of filter membrane under the low vacuum puffing regimens must be increased, the performance of the special-purpose filter membrane of MBR could be more complete sign gone out.
The permeable amount that adopts the vacuum decompression method to measure miillpore filter is also arranged, as shown in Figure 3, this device has adopted the method for vacuum decompression, similar to the membrane bioreactor practical operation situation, but lacked stirring apparatus, when its bioassay standard particle hold back effect the time, concentration polarization phenomenon, the authenticity of influence evaluation and test can inevitably take place on film surface.
