摘　　要：用气升式内循环蜂窝陶瓷反应器(IAL-CHS)对富营养化原水进行生物修复,反应器采用自然挂膜法低温启动挂膜,第9天就完成挂膜。经过5个月的运行,在HRT为1.03 h时,反应器对NH4+-N去除率达到84.8%～99.2%,水力负荷可达到33.68 m3/(m2.d),NH4+-N容积负荷达到0.60 kg/(m3.d),NH4+-N去除速率能达到0.53 kg/(m3.d)。对NO2--N,TP,CODCr,TOC,UV254,浊度的去除率分别为40.7%～69.9%,9.26%～27.1%,8.22%～41.1%,9.49%～29.8%,11.4%～19.5%,27.0%～62.8%。微生物镜检表明此反应器生物相丰富,生物量大。Internal Airlift Loop with Cells Immobilized onto Ceramic Honeycomb Support （IAL-CHS） reactor was used for bioremediation of eutrophic source water. The reactor was started up at a lower temperature with natural biofilm formation and the biofilm was successfully formed in the ninth day. After five months＂ operation, the removal rates of NH4-N was 84.8 - 99.2% when hydraulic retention time was 1.03 h, the hydraulic loading could reach 33.68 m3/（m2-d）, volume loading of NH4＋-N could reach 0.60 kg/（m3.d）, and NH4＋-N removal rate could reach 0.53 kg/（m3.d）. The removal rates of NO2--N, TP, CODc, TOC, UV254, and turbidity were 40.7% - 69.9%, 9.26% - 27.1%, 8.22% - 41.1%, 9.49% 2 29.8%, 11.4% - 19.5%, and 27.0% - 62.8%, respectively. The microscope of the IAL-CHS reactor showed the biophase was rich and biomass was large.
