| 摘 要： | 利用改进的通量阶梯式递增法对膜-生物反应器(MBR)中的临界通量进行了测定,同时对不同缓冲时间下的测定值差异进行了研究.结果表明:延长缓冲区的等待时间,可有效降低通量-跨膜压差(Flux-TMP)与通量-膜渗透性(Flux-Permeability)的不对称性,削弱Flux-TMP滞后效应,降低膜面残余污染阻力,提升次临界区内污染可逆性.附增缓冲区的临界通量测定法可更好地表征膜组件过滤性能随通量的变化规律,减缓可逆污染对测定结果产生的影响.

| Abstract: | The critical flux of submerged flat membrane bioreactor(MBR) was measured by an improved flux-stepwise method and the measured values under different relaxation time were analyzed.The result was that with longer relaxation time,asymmetry of Flux-TMP and Flux-Permeability decreases remarkably with much lower membrane residual resistance and better fouling reversibility in sub-critical flux zone and without obvious hysteresis.The relaxation-zone-attached flux-stepwise method can better describe the principle ... |
