摘　　要：湖泊底泥富营养化是导致湖泊水体富营养化的主要原因,本研究以湖北省天门市某湖泊富营养底泥为处理对象,利用挺水植物梭鱼草与固废基固化剂的有效协同,实现富营养底泥的有效治理。结果表明,采用单一HD型固化剂处理底泥,总氮、氨氮、硝态氮的去除率分别为9.6%、28%、25%(1%固化剂),14.7%、28.9%、28.57%(2%固化剂);采用单一梭鱼草处理底泥,总氮、氨氮、硝态氮的去除率分别为5.05%、15.1%、14.29%;HD型固化剂耦合梭鱼草处理底泥,总氮、氨氮、硝态氮的去除率分别为37.54%、68.5%、62.5%(1%固化剂),37.7%、63.46%、65.71%(2%固化剂),对氮素的去除效果明显优于单一处理方法。梭鱼草与HD型固化剂协同治理富营养底泥的实验研究结果可为富营养湖泊的治理提供一定的理论基础和技术支撑。Lake sediment eutrophication is the main cause of lake water eutrophication,the authors took the eutrophic sediment of a lake in Tianmen City,Hubei Province as the treatment object,and used the effective synergy of the water-lifting plant Barracuda grass and the solid waste-based curing agent to achieve effective treatment of eutrophic sediment.The results showed that the removal rates of total nitrogen,ammonia nitrogen and nitrate nitrogen were 9.6%,28% and 25%(1%curing agent)and 14.7%,28.9% and 28.57%(2% curing agent),respectively.The removal rates of total nitrogen,ammonia nitrogen and nitrate nitrogen were 5.05%,15.1% and 14.29%,respectively.The removal rates of total nitrogen,ammonia nitrogen and nitrate nitrogen were 37.54%,68.5%,62.5%(1%curing agent)and 37.7%,63.46% and 65.71%(2% curing agent),respectively,and the removal effect of nitrogen was significantly better than that of the single treatment method.The experimental results of the synergistic treatment of eutrophication sediment by barracuda grass and HD curing agent can provide theoretical basis and technical support for the treatment of eutrophic lakes.
