摘　　要：对PAC/MBR和MBR工艺处理微污染水源水的效能进行对比研究。结果表明,PAC/MBR对CODMn、UV254具有更好的去除效果,在浊度、氨氮的去除上,PAC/MBR没有明显优势。通过检测混合液中EPS的含量、分析膜出水通量的变化趋势,可以发现PAC的加入,增强了反应器内的生物活性,改变了系统混合液中EPS的形态及含量,改善了膜出水通量。说明PAC有助于减缓膜污染,提高系统的稳定性。A comparative research on PAC/MBR and MBR process for treating micro-polluted surface water had been operated,the results showed that the PAC/MBR had better effects in the removal of CODMn and UV254 while had no obvious advantages in the removal of turbidity and ammonia nitrogen. Through detecting the content of EPS in the mixed fluids, analyzing the trends of the effluent flux, It can be found that ,the adding of PAC can strengthen the biological activity inside the reactor,leading a divergence in the content and distribution of EPS and improve the effluent flux of membrane. In another way, PAC can alleviated the extent of fouling as well as contribute to the system＇s reliability.
