| 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（IMR-ICW）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 spectrum and highly efficient degradation bacteria Lysinibacillus sp. FS1 (CCTCC M 2013561) were used to treat rural comprehensive wastewater 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 phosphorous (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 process. |
