摘　　要：采用气升式内循环蜂窝陶瓷反应器(IAL-CHS)对受污染黄浦江支流进行生物修复,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,反应器对氨氮去除率达到84.8%～99.2%,水力负荷可达到33.68 m3/(m2.d),氨氮容积负荷达到0.60 kg/(m3.d),氨氮去除速率能达到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 Cell Immobilized onto Ceramic Honeycomb Support（IAL-CHS） reactor was used for bioremedy of polluted water in the Branches of the Huangpu River.The natural biofilm formation was used for the reactor to start up at a lower temperature and the biofilm was successfully formed in the ninth day.After the start-up for five months,the removal rate of NH4 ^＋-N was 84.8%-99.2% when hydraulic retention time was 1.03 hour,and the hydraulic loading could reach 33.68 m^3/（m^2 · d）,volume loading of NH4 ^＋-N could reach 0.60 kg/（m^3 · d）,NH4 ^＋-N removal could reach 0.53 kg/（m^3 · d）.The removal rates of NO2^——N,TP,CODCr,TOC,UV254 and turbidity were 40.7%-69.9%,9.26%-27.1%,8.22%-41.1%,9.49%-29.8%,11.4%-19.5%,27.0%-62.8% respectively.The microscope of the IAL-CHS reactor showed the biophase was rich and biomass was large.
