摘　　要：对上海市不同区域疏浚泥的颗粒粒径、化学成分、毒性、养分等理化性质进行测定,继而对其资源化可利用性进行了分析。结果表明,上海市疏浚泥可定性为粘质粉土和粉质粘土;3个采样区的样品均没有达到清洁疏浚泥的标准。内河航道疏浚泥养分充足但镉污染稍显严重,采取重金属预防措施后适宜作为农作地和湿地矿山修复用地;黄浦江码头前沿和长江码头前沿疏浚泥有机质严重不足,仅适于在绿地、绿化带、防护林等处使用;3处疏浚泥均可制陶粒和制砖,亦可用于围内吹填工程,但需事先对疏浚泥里的重金属成分进行固化。For dredged mud resource utilization,the particle size,chemical composition,pollutant content and nutrient content in the dredged mud from several sampling areas of Shanghai are measured.The feasibility of transforming dredged mud into regenerative resources is also discussed.Results show that the dredged mud in Shanghai mainly consists of silt.The dredged mud sampled from inland waterway could be used as agricultural land and restored material for wetland and mine.Because of the insufficient organic substance,the dredged mud sampled from the Huangpu River and the Yangtze River could only be available in landscape engineering.Stabilized sediment could be a suitable raw material for producing ceramist and brick.
