摘　　要：制备磁性粉末活性炭,并利用磁性粉末活性炭小试装置研究该工艺对江苏省某微污染原水的处理效能,为磁性粉末活性炭工艺提供理论基础。结果表明:粉末活性炭和3种不同负载比的磁性粉末活性炭在稳定阶段对氨氮的去除率均可达到90%以上,说明装置内存在硝化作用;4种材料对DOC、COD_(Mn)、UV_(254)的去除率均在20%左右,随着负载比的提升,材料对氨氮和有机物的去除率提高,表明磁性物质的负载会促进硝化细菌和异养菌的生长。磁性物质会影响微生物群落结构种类的比例。磁性粉末活性炭工艺在长期运行中保持较高的稳定性,4种材料对铁离子总体呈现截留作用。Magnetic powdered activated carbon（MPAC） was prepared to research on the treatment effect of micro-polluted raw water in Jiangsu Provience by the lab-scale reactor, which could provide theoretical principle for MPAC process. Results showed that more than 90% of ammonia was removed which indicated that nitrification occurred in the four reactors （one was PAC reactor and the other three reactors were PAC with different load ratio of iron oxide NPs）. The removal of DOC, CODMn and UV254 reached about 20%. With the increase of load ratio, the removal of ammonia and organic matters increased, indicating that iron oxide NPs could promote the growth of nitrifying bacteria and heterotrophic bacteria. Magnetic material can affect the proportion of microbial community structure. MPAC process maintains high stability in long term operation, and Fe ion is performed as retention by four materials based on the measured concentration of total Fe ion.
