以膨润土、粉末活性炭（PAC）为吸附剂，考察了其对微污染物（NH3 N、UV254）的去除效果。通过改变膨润土／ PAC的投加量，考察了其与 MBR的组合工艺对氨氮与 UV254的去除效果及微生物活性、膜比通量和出水中有机物残留颗粒粒径的影响。结果表明膨润土对 UV254的吸附能力弱，平均去除率仅为20．02％，而 PAC对 UV254的去除率可达89．68％。膨润土 MBR能有效去除 NH3 N，平均去除率达92．8％，但对 UV254的去除率仅为51．13％；PAC与 MBR联用能有效去除 NH3 N、UV254，去除率分别为94．5％、89．55％。出水中有机物残留颗粒物不仅数量少，颗粒粒径分布范围也变窄，大粒径颗粒绝大多数得到去除。

In this paper,the adsorption effects of pollutants such as NH 3 N,UV 254 were investigating by using bentonite and powdered activated carbon (PAC)as adsorbent. The effects of MBR combined with different dosages of bentonite/ PAC on removal of NH3 N and UV254 ,and influence of microbial activity,membrane specific flux and particle size of organic residue in effluent were studied. The results show that the adsorption effect of bentonite on UV254 is weak and the average removal rate is only 20. 02%;while PAC can remove UV254 effectively and the average removal rate is 89. 68% . Bentonite MBR can effectively remove NH3 N,the average removal rate is 92. 8%,but effect of bentonite MBR on removal of UV 254 is not obvious and the average removal rate is only 51. 13% . PAC combined with MBR can effectively and stably remove NH3 N and UV254 ,and the average removal rates of NH 3 N and UV254 are 94. 5% and 89. 55%,respectively. Not only the number of molecular particle in effluent is small,but also the molecular particle size distribution range is narrower. And the vast majority of the large size of the particles is removed.
