| 摘 要： | 研究了加压MBR膜通量衰减规律，膜污染阻力的分布；尝试了空曝、水反冲洗、压缩空气反冲洗、物化清洗四种膜清洗方式的膜通量恢复．研究结果表明：加压MBR膜通量衰减迅速，运行17d后膜通量衰减83．5％；膜污染阻力主要由凝胶极化阻力Rp和内部污染阻力Rif构成。

| Abstract: | The law of membrane flux attenuation and membrane fouling resistance of submerged pressurized membrane bioreactor(P-MBR) were studied, and the measures to reduce the membrane fouling were baken to enhance membrane flux, such as no-effluent aeration, air and water backflush, physical-chemical cleaning. The results showed that the membrane flux declined quickly, and the flux reduced by 83.5% after operating for 17d 17 th/d; the membrane fouling resistance was mainly caused by polarization layer resistance(Rp)and internal fouling resistance(Rif). |
