目的:探究城市河道生态清淤方案及淤泥脱水处理处置方法。方法:根据河道的环境特点和施工难点以及淤泥特性，综合分析不同生态清淤工艺方法以及淤泥资源化利用方法。结果:生态型和景观型河道，采用智能扫吸式清淤工艺；综合型和工业型河道，采用绞吸式清淤工艺。2‰阳离子聚丙烯酰胺、3%聚合氯化铝加1.5‰阴离子聚丙烯酰胺配制的絮凝药剂的絮凝效果较好。板框压滤脱水法和高压带式压滤脱水法，可使脱水后的淤泥含水率降至30%～50%。脱水后的淤泥可用做种植营养土或基质材料，以及覆盖土、回填土与烧结砖和陶粒的生产原料。结论:生态清淤能有效地处理不同城市河道的淤积问题，并进一步为淤泥资源化利用提供了可行方案。
Abstract：Aims: This paper aims to study the ecological dredging scheme and sludge dewatering treatment and disposal methods for urban rivers. Methods: Based on the environmental characteristics and construction difficulties of river channels, as well as the characteristics of the silt, a comprehensive analysis was conducted on different ecological dredging techniques and methods for the utilization of silt resources. Results: Ecological and landscape rivers were desilted by intelligent sweeping and suction dredging technology. Comprehensive and industrial rivers were desilted by cutter suction dredging process. It was found that the flocculation chemicals formulated with 2‰ cationic polyacrylamide, 3% polymeric aluminum chloride and 1.5‰ anionic polyacrylamide had a better flocculation effect. The plate and frame filter press dewatering method could the high-pressure belt filter press dewatering method could reduce the moisture content of the dewatered sludge to 30%～50%. The dewatered sludge could be used as nutrient soil, substrate material for planting, mulch, backfill soil as well as the material for sintered bricks and ceramsite. Conclusions: The ecological dredging scheme can effectively deal with the siltation problem of different urban rivers and further provide a feasible scheme for the resource utilization of silt.
