摘　　要：结合河流、水库污染与淤积现状,立足于环境疏浚清淤思想,从振荡脉冲射流气举疏浚与清淤的工艺流程、余水处理、污泥回用等技术上进行了全面的分析.明确指出环境清淤工艺中通过脱水技术,可以减少污泥总量,从而减少堆场的大小;通过对余水的处理,减少二次污染;处理后的污泥可以作为河岸、园林、道路的绿化用土,达到污泥的再利用.以花溪河流域综合治理为工程实例,详细阐述了环境清淤中的参数选取和生产效率,为山区河流与水库的环境清淤指出了新的方向.Being established in the thought of environment dredging, the crafts flow of water jet airlift dredging and treating of surplus water as well as circle using of mud polluted have been analysed following the status in quo of pollution of the fiver and reservoir. Definitely, it has been pointed out that the total of mud will be reduced with the technique of dehydration so as to reduce the volume of mud stack. At the same ring the surplus water. The mud which had been treated can be time, it will be reduced for pollution secondly by treaused as soil of fiver or gardens or road for the recycle. Then, the parameter and efficiency of production in HuaXi river valley integration treating project have been expatiated particularly in environment dredging. It indicates the new way for environment dredging in river and reservoir at the mountainous area.
