In film biological treatment, fouling membrane is one of of paramount importance influence factor, directly influences this technique and uses
Economy and stability, in running the control of fouling membrane be when in cephacoria biological treatment technical research and application
One of important link.Fouling membrane refers to that microgranule in the sewage being contacted with film, colloidal particle or solute transportation and film are existed
Physics, chemistry, biochemical action or mechanism, tired at film water interface in face or fenestra internal adsorption, deposition and microorganism
Long-pending, cause membrane aperture to diminish or block, make the phenomenon that the transmission flow of film and stalling characteristic are greatly lowered.Fouling membrane not only contracts
The short service life of film, and directly result in pumping suction nozzle in film separation system and the aeration rate for film surface clean increases
Plus.
At present, the control of fouling membrane is carried out using physical means and chemical cleaning method, and perforated pipe aerating regulation is topmost
Physical cleaning means, can rush de- deposition sludge blanket on the surface of the film by excess aeration, to extend the time of Chemical cleaning
Interval.But it is difficult to meet using perforated pipe aerating regulation developing result in actual motion and require, and the gas-water ratio designing up to more than 20,
Account for the 80-90% of whole system total energy consumption, exceed well over the gas-water ratio of traditional activated sludge process 6-8, this is to cause membrane biological reaction
Device energy consumption is higher, operating cost is higher and membrane module frequent clean and the main cause changed.
Sloping plate deposition mainly make use of shallow pond precipitation principle, by arranging swash plate, shortens granule settling height, thus contracting
The short sedimentation time, be equivalent to the desilting area that increased sedimentation tank, thus improve treatment effeciency.Sloping plate deposition is as efficient
One kind of sedimentation, all has employing in the process of all kinds of waste water, compared with membrane separation technique, shortcoming essentially consist in main according to
By physical sedimentation principle, need to arrange single sedimentation tank, higher to the uniformity requirement of water distribution, this limits to a certain extent
Its range of application.
Content of the invention
The purpose of this patent is, for the shortcoming of fouling membrane Producing reason and common control device, solves routine
