摘　　要：从水环境、水生态、底泥污染、蓝藻水华等方面概述了太湖水生态环境现状;考虑底泥污染、湖泛治理等情况,确定清淤范围主要集中在竺山湖、梅梁湖、西沿岸和贡湖等重点湖湾区,介绍了针对太湖清淤而研发的高效生态清淤固淤一体化智能环保装备船。针对目前清淤尾水处置难题,提出了对关键污染因子总氮靶向去除的尾水深度净化研究建议;针对底泥资源化利用难题,提出了底泥资源化利用产业化分析及回用于太湖生态治理的建议。The current situation of water ecological environment in the Taihu Lake is summarized from the aspects of water environment,water ecology,sediment pollution,cyanobacteria bloom,etc;Considering the situation of sediment pollution,lake bloom control,etc.,it is determined that the dredging scope is mainly concentrated in the key lake bay areas such as Zhushan Lake,Meiliang Lake,the west coast and Gonghu Lake.This paper introduces the highly efficient ecological dredging and silting integrated intelligent environmental protection equipment ship developed for the dredging of the Taihu Lake.Suggestions have been put forward for the deep purification of tailwater by targeting the removal of key pollution factors such as total nitrogen,in response to the current difficulties in the treatment of dredged tailwater;Aiming at the difficult problem of sediment resource utilization,this paper puts forward the industrialization analysis of sediment resource utilization and the suggestions of reuse for ecological management of the Taihu Lake.
