疏浚清淤脱水工艺及工程应用进展

目前针对疏浚底泥的减量化与资源化技术研究成果颇多，工程应用却依然存在较多技术难题。针对疏浚技术成果工程化应用难的问题，对目前疏浚清淤工程常用的疏浚方法、底泥脱水工艺、絮凝药剂的选配以及后期的余水深度处理技术工程应用进展进行总结分析，指出研究成果工程化应用的难点，并对今后疏浚工程管理与研究提出建议：一方面，应加强内河湖库底泥污染基础调查及治理规划，完善和健全相关法律法规与技术标准；另一方面，应加强设备智能化与自动化研发，促进产学研合作，加强成果转化。

Dredging dehydration technology and engineering application process

Nowadays,although there are a lot of research achievements on reducing and reusing dredged sediment,there are still many technical problems in dredging engineering application.In view of the difficulty of engineering application of dredging technology achievements,we analyze the dredging method,dewatering process,flocculation agent and residual water treatment,point out the reasons of difficulties in engineering application,and put forward suggestions for the management and research of dredging projects.On one hand,it is necessary to strengthen the basic investigation and treatment planning of sediment pollution in rivers and lakes,and improve relevant laws,regulations and technical standards;on the other hand,we should strengthen the research and development of equipment intelligentization and automation,promote industry-university-research cooperation,and strengthen the application of research achievements.
