摘　　要：采用生物激活技术、多功能生态浮岛与磁化抑藻曝气技术集成的多自然生态技术对江苏省太仓市樊泾河进行生态修复的现场试验。结果表明生物激活剂对存在点源污染的感潮河道具有较好的修复效果,NH3-N、TP、CODCr和叶绿素α去除率分别达到61.8%、50.4%、31.3%和75.2%以上。多自然生态技术可以发挥不同技术间的协同作用,进一步改善水质并稳定修复效果,强化对藻类的控制,明显提高水体的透明度。Field test of bioremediation was conducted in Fanjing River, Taicang City, Jiangsu Province, by multi natural ecological treatment technology which consisted of biostimulant, ecological floating bed and aerator with algae control. The results showed that biostimulant had better remediation effect on the tidal river with point source pollution. The removal efficiencies of NH3-N ,TP,CODcr and chlorophyll-α were above 61.8%,50.4%,31.3% and 75.2%, respectively. Multi natural ecological treatment technology could exert synergistic effect of three technologies to improve water quality and maintain stable remediation effect, enhanced algae control and the transparency of water.
