Skill is membrane bioreactor (MBR).The group technology of one depth logos of activated sludge process, i.e., live in original denitrogenation dephosphorizing
Property sludge processes on the basis of, increase coagulation, plate-spinning filter, the technique such as sterilization, but the technological process length, equipment be more, floor space
Greatly, stably reaching standard is difficult to indexs such as ammonia nitrogen total nitrogens.Membrane bioreactor (MBR) with floor space it is little, effluent quality is excellent, can
The advantages of enhanced biological is processed, China's land used is limited, developed area good market prospect, but MBR techniques are still immature,
Membrane flux is low, high energy consumption, service life are short, limits further genralrlization use.
Dynamic Membrane (Dynamicmem-brane) is a kind of emerging sewage disposal film, is by being formed on film base material surface
Sludge blanket plays a kind of new membrane module of accurate crown_interception, and wherein self-forming dynamic membrane is by sludge flco in filter process
(microorganism and its metabolite) is accumulated to form film layer for class coating material.Which forms time and thickness and Biomass etc. with operation bar
Part is closely related, has reported in literature sludge flco cumulative speed to be about 0～50g/ (m2H), thus " film layer " forms relatively slow
And it is difficult to stablize, the time is longer to cause Dynamic Membrane to be formed, and generally at 30 minutes to a few houres, thus initial stage water quality is difficult to
Meet and require (effective filtration is only formed to certain thickness competence exertion in sludge blanket and acted on), big capacity of returns can only be adopted
To film forming, so as to increased Qian Dao ponds load；Secondly, Dynamic Membrane operationally increased because film layer easily occurs in high sludge concentration
Hurry up, cause effluent flux to decline, effective cycle of operation is relatively short, and lack effective control measure；Besides, Dynamic Membrane
Backwash effect is poor, and effluent flux recovery rate is low, causes normal aquifer yield little, is easy to produce irreversible membrane fouling after time length, leads
Cause medicine to wash frequently, increased operating cost and complex operation degree.This three big defect becomes the good cost of the spontaneous operational effect of restriction
Low dynamic film component effectively utilizes major obstacle.
