With being kept completely separate for sludge retention time (SRT), short HRT and long SRT (or the blowdown mud period is long) are can be realized simultaneously, therefore
Has the function that volumetric loading is high, anti-load impact ability is strong；
3. in the process of running, film is vulnerable to pollution, flux depression speed is fast, this is because membrane aperture is 0.1um-
0.4um makes the deposition of particulate matter on the surface of the film, bacterium and macromolecular in film surface etc. adsorb or enter membrane material
In, or the blocking of fenestra occurs.If cleaning and safeguarding not in time, cause that water yield reduces and effluent quality is unstable reaches
Mark accelerates membrane material service life short, and then makes troubles to operation and maintenance management, causes operating cost height；
4. the separation membrane in the membrane bioreactor of current industrial applications is mostly hollow-fibre membrane or plate membrane,
Its membrane aperture is 0.1um-0.4um, and the operating flux of its membrane component piece is 10L/ ㎡ ﹒ h-50L/ ㎡ ﹒ h by taking plate membrane as an example, is shown
So because the water yield of its membrane component piece is low, in engineering design and implementation stain disease processing, required membrane area quantity will be with film
Number of elements piece accumulates directly proportional matching, i.e. membrane aperture is smaller, and membrane component quantity piece, which will increase, is accumulated as required membrane area
Quantity could meet engineering design and apply real required water yield (membrane flux), thus cause separation membrane manufacturing cost and
Its project cost is higher, poor to the cost performance of MBR membrane reactors, hinders its extensive use and use value.
