| 摘 要： | 探讨了一体式膜生物反应器出水方式对膜污染的影响和采用Flundlich等温吸附方程来表征膜污染的可行性.在相同运行条件下,实验测得真空抽吸-空气反吹、真空泵抽吸和自吸水泵抽吸3种出水方式的吸附曲线方程依次为2.59c1/0.957e 、7.415c1/1.369e和7.10c1/1.015e. 试验结果表明,膜生物反应器的出水方式对膜污染有明显的影响,其中真空抽吸-空气反吹间隙运行方式引起的膜污染程度最轻.采用Flundlich等温吸附方程表征膜污染状况是可行的.

| Abstract: | The influence of effluent discharging modes on membrane fouling in a submerged membrane bioreactor was evaluated, and the feasibility of the characterization of membrane fouling using Flundlich isothermal adsorption equation was also explored in this paper. Under the same operation conditions, the adsorption equations of three discharging modes of vacuum pump drawing combined with air back-blowing, vacuum pump drawing and suck pump drawing were 2.59ce1/0.957, 7.415ce1/1.369 and 7.10ce1/1.015. Experiment results showed that the effluent-discharging mode had a significant influence on membrane fouling in the submerged membrane bioreactor. Among three discharging modes, the membrane fouling degree in the mode of vacuum pump drawing combined with air back-blowing was the lightest. The experimental results also indicated that Flundlich isothermal adsorption equation is applicable in the characterization of membrane fouling. |
