| 摘 要： | 主要对装备新型纤维膜的生物反应器在不同的操作模式下对渗透通量的影响进行研究.结果表明，配备新型纤维膜的MBR，可以减少阻力，提高渗透通量，降低的总阻力从9.649下降为5.962，渗透通量增加15~20 L/m2h.同时，间歇运行模式的渗透通量好于连续运行模式，其渗透通量的值高达20 L/m2h和25 L/m2h，可消除由于结块效应和浓度极化效应所产生的可逆堵塞所产生的影响.

| Abstract: | In this paper,the effects of experimental conditions including the membrane bioreactor (MBR) equipped novel device and different operating modes on permeate flux were studied.The results show that the MBR equipped novel device can reduce the resistance and enhance the flux,decreasing the total resistance (Rt=9.649) to 5.962 and increasing the permeate flux to 15~20 L/m2h.The permeate flux of intermittent operating mode is more than that of continuous operation and the value of the permeate flux is between 15l/m2h and 20l/m2h.The MBR equipped novel device which adopting intermittent operating mode is most effective in this study and the value of permeate flux is between 20l/m2h and 251/m2h. |
