For the new bio membrane technology of carrier, the research [1] of end of the seventies in last century Yeh and Jenkins is started from.Its two features allow
Its contaminant removal efficiency with higher, first is that bubble-free aeration, the other is the incorgruous mass transfer of oxygen molecule and pollutant.The former
The mass-transfer efficiency of oxygen can be improved, the latter is most important for realizing one-step autotrophic nitrogen removal function, can make nitrobacteria and anaerobism
Ammonia oxidation bacteria is distributed in the both ends of biomembrane, does not interfere with each other, cooperates with denitrogenation.Therefore membrane aeration biomembrane (MAB) system becomes single
The hot spot of grade autotrophic denitrification research, but the rapid biofilm of autotroph and the stability of biomembrane, thickness control and activity
Holding be its research difficult point [2].Traditional MABR biofilm is by inoculation of activated-sludge, and the starting time is long, it is difficult to compared with
Stable biofilm structure is formed in short time, and controls biofilm thickness using backwash again in the later period, program is cumbersome,
It is big [3] to control difficulty, for the anaerobic ammonia oxidizing bacteria of slow growth in autotrophic denitrification, this biofilm technology is difficult to
Achieve the purpose that quick start reactor.Such as Zeng Qingnan [4] et al. compared pvdf membrane and PP membrane fiber biomembrane attachment feelings
Condition, biological attachment amount is respectively 32.40gm at the 25th day-2And 29.12gm-2.Biological attachment amount increases after operation in 90 days
To 35.62gm-2And 30.63gm-2, the biofilm time is longer.Currently, there are also the researchs of this respect, such as:

Currently, the applicant has been developed that a kind of side of plate membrane rapid biofilm using imbedded microbe gel
Method, this method propose that the surface that the gel rubber material for being embedded with microorganism is loaded to traditional aeration film forms composite membrane aeration and biological
Film (Composite Membrane Aerated Biofilm, CMAB), so as to quickly have in aeration film surface formation
The gel layer of microbial activity reaches best by controlling the embedding sequence of reasonable biofilm thickness and different microorganisms
Denitrification effect.How to guarantee during using this method biofilm effect, guarantee biofilm thickness, improve biofilm stability at
For important research direction.If lacking apparatus for coating, the uneven of gel layer thicknesses will lead to, increase the biofilm time, reduce
Biofilm efficiency, therefore develop a kind of dedicated apparatus for coating and be very important.
