摘要
由于有机污染物和重金属复合污染场地往往需要修复才能进行开发,因此对典型SVOCs和砷镍复合污染场地的修复进行了研究。首先对SVOC和砷、镍重金属复合型污染场地土壤样品进行了详细分析和研究,针对场地特征进行了修复药剂选择和配比实验,在此基础上对修复药剂的作用效果和机理进行了详细分析和研究,确定了各药剂在使用过程中的用量、pH值和含水率等关键工艺参数及修复技术要求,并对工程应用提出了指导性意见,希望能对类似污染场地工程修复提供一定参考。
The complex contaminated sites of organic pollutants and heavy metals often need repair before development.The remediation of typical SVOCs and as Ni complex contaminated sites was studied.Firstly,the soil samples of SVOC,arsenic and nickel contaminated sites were analyzed and studied in detail.According to the characteristics of the site,the selection and proportion of remediation agents were tested.On this basis,the effect and mechanism of remediation agents were analyzed and studied in detail.The key process parameters and remediation technologies such as dosage,pH value and moisture content of each agent in the process of use were determined.It is hoped that it can provide some reference for similar contaminated sites.
