| 摘 要： | 采用涤纶网加工的微网膜组件与厌氧反应器结合构成厌氧微网生物反应器用于处理城市生活污水,考察了反应器在停留时间4 h、8 h和16 h、膜通量72 L/m2.h和36 L/m2.h、微网目数250目和380目条件下的运行特性。试验结果表明,反应器的停留时间与进水COD的去除率成线性关系,停留时间越长,COD去除率越高,但对TN的去除影响不大;膜通量的减小有利于出水水质的变好;提高微网目数有利于提高微网动态膜的截留性能。

| Abstract: | The filter modules made of Dacron were submerged into an anaerobic bioreactor to form a submerged anaerobic fab- ric bioreactor（AnFBR）. The established AnFBR was employed for treating domestic wastewater. The operating characteristics of the AnFBR were investigated under different conditions（ HRT =4h ,8h and 16h; membrane flux = 72 L/（ m2 . h）and 36 L/（ m2 . h） ; mesh of Dacron = 250 and 380）. The results showed that there was a linear relationship between the HRT and COD of the effluent. The longer the HRT, the higher removal efficiency of COD, but there was nearly no effect on TN removal. The reduction of membrane flux achieved better effluent quality. The high - efficient solid - liquid separation was achieved when a higher mesh of Dacron was used. |
