| 摘 要： | 为了降低陶瓷膜-生物反应器的能耗、同时提高膜的渗透通量，本文将气升式外循环引入膜-生物反应器的设计。实验条件下，搭建了气升式陶瓷膜-生物反应器装置，研究了导气管直径、气升位置、气速、气体性质等循环条件对渗透通量的影响；并在相同条件下与液体不循环的过滤相比较，证明采用气升循环可以较大提高膜的渗透通量。

EXPERIMENTAL RESEARCH ON PERMEATE FLUX OF AIRLIFT CERAMIC MEMBRANE-BIOREACTOR |
| |
| Abstract: | To raise permeate flux of ceramic membrane, reduce industrial specific power consumption, airlift circulation was led into membrane bioreactor under the suction filtration. Experiment was done under airlift condition of nozzle diameter, airlift location, airlift speed, gas nature etc, and comparisonwas carried out with the no airlift condition. Data has proved that the steady permeate flux can rise greatly with airlift circulation. The airlift membrane-bioreactor is potentially applicable in water treatment and bioengineering fields. |
