中文摘要:
      为高效处置深圳河第四期工程中河道重金属污染土,采用固化/稳定化技术,对工程范围内的污染土进行取样检测和试验分析。结果表明,添加8%的水泥并固化15 d后,固化物料浸出液危害成分浓度满足渗滤液污染物浓度(TCLP)的要求,污染土固化后的无限抗压强度(UCS)大于1 MPa,可满足工程要求,验证了河道重金属污染土固化/稳定化技术在深圳河第四期工程中应用具有可行性。
英文摘要:
      In order to dispose of heavy metals contaminated soil in the Phase IV project of the Shenzhen River efficiently, solidified/stabilized technology was used to sample, test and analyze contaminated soil within the scope of the project. The results show that after adding 8% of cement and curing for 15 days, the concentration of hazardous components in the leachate of the solidified material meets the requirements of leachate contaminant concentration (TCLP). The unlimited compressive strength (UCS) of the contaminated soil after curing is greater than 1 MPa, which can meet the engineering requirements. It was verified that the solidification/stabilization technology of heavy metal contaminated soils in river channels is feasible in the Phase IV project of Shenzhen River.
