The Demonstration Case Project of Heavy Metal Contaminated Sediment Treatment in a Historical River in Gansu Province
The engineering examples,a river left over by history,heavy metal pollution of sediment in baiyin,gansu province as the research object,comprehensive analysis of river sediment of heavy metal pollution,pollution range,quantity,rehabilitation goals,time limit,cost and project implementation conditions,combining with project practice,in order to"classification management,quality,and the use,the safe disposal of"the green concept of sustainable repair for the principle,For severely polluted sediment,excavation-landfill remediation technology is adopted,and for slightly polluted sediment,solidification/stabilization remediation technology is adopted.The project has been implemented with both quality and quantity guaranteed,and passed the effect evaluation and completion acceptance at one time,and the remediation effect meets the design requirements.The implementation of this project provides a reliable guarantee for the safety of the water quality of the Yellow River,vigorously promotes the protection of the Yellow River basin,and provides practical experience for the domestic development of river sediment control projects.
