摘　　要：纳污水体的整治成为炙手课题,但对东北高寒盐的纳污水体净化技术未完善。本研究以生态基为膜载体,利用其与芦苇人工浮岛、原位优势菌形成的耦合修复体系开展东北地区某炼化纳污水体净化效果研究。研究表明,当在温度25℃,溶氧浓度4 mg/L,pH值8.0,以碳素纤维草为材料作为生态基,投放密度2根/浮岛单元的环境下时,该耦合系统对纳污上覆水体COD、NH_(4)^(+)-N、TN和TP平均去除率为最佳,可达到78.40%、79.18%、84.05%和79.76%。实现了炼化纳污水体的原位净化目标,提升了上覆水污染物的去除率,为该技术在炼化纳污上覆水体原位治理工程化应用中系统构建与运行提供理论基础。The purification technology of nanoscale wastewater has not been perfected for the purification of nanoscale wastewater in the alpine salt of Northeast China.In this study,we took the ecological base as the membrane carrier,and utilized its coupled restoration system formed with reed artificial floating island and in situ dominant bacteria to carry out the purification effect study of a refining nano-wastewater body in Northeast China.It was shown that the coupled system had the best average removal rate of COD,NH_(4)^(+)-N,TN and TP from the overlying nannofossil water body,which could reach 78.40%,79.18%,84.05%and 79.76%,when the temperature was 25℃,dissolved oxygen concentration was 4mg/L,pH value was 8.0,and the ecological substrate was made of carbonaceous fiber grass,and the density of placement was 2 roots/floating island unit.It achieved the goal of in situ purification of refining and chemical nuisance overlying water bodies and improved the removal rate of pollutants in overlying water,providing a theoretical basis for the construction and operation of the system in the engineering application of this technology in the in situ treatment of refining and chemical nuisance overlying water bodies.
