摘要
针对我国城市内河治理产生的疏浚底泥量大且处理难的问题,系统归纳了现有疏浚底泥再生利用技术研究和应用现状。在此基础上分析了就地处理、土地利用、建材制备、路基填筑等底泥资源化处理的四大路径的优缺点,并提出土地利用是生态综合整治中内河底泥再生利用的最佳路径,但需要重视底泥中重金属种类及含量。
Due to the large amount of dredged sediment caused by the governance of urban inland rivers in China and the difficulty of treatment,this paper systematically summarizes the research and application status of the existing dredged sediment recycling technology paths,and analyzes the advantages and disadvantages of four paths of dredged sediment resource usage,on-site treatment,land use,building materials preparation and subgrade filling.It is suggested that land use is the best way to recycle sediment of the inland river in ecological comprehensive remediation,however,it is necessary to pay attention to the types and contents of heavy metals in sediment.
