摘　　要：利用广谱高效毒害有机物降解菌Lysinibacillus sp.FS1(CCTCC M 2013561)开展固定化微生物反应器-人工湿地(IMRICW)组合工艺对工业型村镇废水处理的工程应用研究。工程运行结果表明,组合工艺对COD、TN、NH3-N、TP和TSS的平均去除率分别达到71.5%、59.5%、56.9%、46.0%和82.9%,其中COD和TSS出水均值达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)中一级A排放标准。GC-MS检测结果发现,固定化微生物反应器对混合废水中10种主要有机污染物的去除率均在50%以上,其中毒害有机物3,4-二氯苯酚和乙酸苯酯的去除率分别达到81.2%和95.6%,其脱毒减害作用可减缓人工湿地的生态压力,显著提升组合工艺对COD(P<0.01)、TN(P<0.01)和NH3-N(P<0.05)的去除效果。 Combined with integrated constructed wetlands（ICW）, an immobilized microorganism reactor（IMR）that contained a broad spec-trum and highly efficient degradation bacteria Lysinibacillus sp. FS1（CCTCC M 2013561）were used to treat rural comprehensive wastewa-ter in industrial cluster towns. The results showed that the immobilized microorganism reactor-integrated constructed wetland（IMR-ICW） system had high removal efficiencies of chemistry oxygen demand（COD）, total nitrogen（TN）, ammonium nitrogen（NH3-N）, total phospho-rous（TP）as well as total suspended solids（TSS）, with average removal rates of 71.5%, 59.5%, 56.9%, 46.0%and 82.9%, respectively. Meanwhile, the effluent quality of COD and TSS met the first class A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB18918-2002）. Furthermore, the results of GC-MS indicated that the removal rates for ten of main organic pollutants in comprehensive wastewater were over 50%by the IMR, and it reached 81.2%and 95.6%for toxic organic compounds 3, 4-dichlorophenol and phenylacetate especially. The detoxification and harm-reduction abilities of IMR could relieve the ecological pressure on constructed wetlands, which significantly increased the removal efficiencies of COD（P〈0.01）, TN（P〈0.01）and NH3-N（P〈0.05）in the combined pro-cess.
