摘　　要：淤泥综合处置需根据清淤计划、监测淤泥中污染物成分及理化指标,调研淤泥处理处置的条件,通过工艺技术和经济费用的综合比选,明确淤泥综合处置方案。苏州市疏浚淤泥建议优先考虑还田还林农用,剩余的淤泥进行脱水干化处理。干化后的淤泥考虑园林绿化、河道堤岸护坡建设、淤泥制建材、回填至宕口及低洼地等,尽可能的提高淤泥资源化利用率,解决淤泥最终出路问题。The silt comprehensive treatment needs to monitor the pollutant composition and physical and chemical indicators in the silt according to the dredging plan,investigate the conditions of silt treatment and disposal,and comprehensively select the sludge comprehensive treatment plan through the comprehensive comparison of process technology and economic costs.The dredging sludge in Suzhou City is recommended to give priority to returning farmland to forestry,and the remaining sludge is dehydrated and dried.The silt after drying is considered as garden greening,river bank slope protection construction,silt making building materials,backfilling to down and low-lying land,so as to improve the utilization rate of silt resources and solve the final outlet of silt.
