Description
Technical field
The invention belongs to a kind of sewage-treatment plant, particularly to a kind of stable operation flux large period length, backwash cycle
Long dynamic film component of the good low cost of spontaneous operational effect and preparation method thereof.
Background technology
The conventional process of waste water treating and reutilizing and the discharge of one-level A is activated sludge process at present--the combination work of depth logos
Skill or be membrane bioreactor (MBR).Activated sludge process--the group technology of depth logos, i.e. lives at original denitrogenation dephosphorizing
Property sludge processes on the basis of, increase the technique such as coagulation, plate-spinning filter, sterilization, but this technological process length, equipment be many, floor space
Greatly, the indexs such as ammonia nitrogen total nitrogen are difficult to stably reaching standard.Membrane bioreactor (MBR) has that floor space is little, effluent quality is excellent, can
The advantages such as enhanced biological process, in China, land used is limited, developed area good market prospect, but MBR technique is the most immature,
Membrane flux is low, energy consumption is high, service life is short, limits further genralrlization and uses.
Dynamic Membrane (Dynamicmem-brane) is emerging a kind of sewage disposal film, for by being formed on film base material surface
Sludge blanket plays a kind of new membrane assembly of accurate crown_interception, and wherein self-forming dynamic membrane is by mud flco in filter process
(microorganism and metabolite thereof) is class coating material accumulation shape film forming layer.It forms time and thickness and Biomass etc. and runs bar
Part is closely related, has reported in literature mud flco cumulative speed to be about 0～50g/ (m2H), thus " film layer " is formed relatively slow
And being difficult to stable, cause Dynamic Membrane to form the time longer, generally at 30 minutes to several hours, thus initial stage water quality is difficult to
Meet and require (effective filtration is only formed to certain thickness competence exertion effect at sludge blanket), big capacity of returns can only be used
To film forming, thus add Qian Dao pond load；Secondly, Dynamic Membrane operationally easily occurs because of high sludge concentration that film layer increased
Hurry up, cause effluent flux to decline, effective cycle of operation is relatively short, and lacks effective control measure；Besides, Dynamic Membrane
Backwash weak effect, effluent flux recovery rate is low, causes normal aquifer yield little, is easy to produce irreversible membrane fouling, leads after time length
Cause medicine to wash frequently, add operating cost and operation complexity.This three big defect becomes the restriction good cost of spontaneous operational effect
Low dynamic film component effectively utilizes major obstacle.
