本文通过对福建省厦门湖里工业区和上杭县某铜矿区土壤按不同功能区划分,进行分区布点采样,然后用US-EPA酸消解方法和浸出毒性测试——TCLP法对其重金属污染进行联合评价。在此基础上,对火电厂废物——粉煤灰先进行水浴改性,然后用于对矿区典型污染区域土壤进行尝试性治理,以期探索一条经济有效的土壤重金属污染治理技术,为粉煤灰废物的综合利用提供一条可行的途径。本论文的主要研究结果如下:工业区的部分土壤有不同程度的Cu、Zn、Hg积累,其有效含量分别在3.6~477.65mg/kg、33.2~215.6mg/kg、0.17~7.76mg/kg之间,局部地区Cu和Cr污染程度比较严重;TCLP法提取的重金...In this paper, EPA-Acid Digestion and EPA-Toxicity Characteristic Leaching Procedure (TCLP) were used to assess the effect of heavy metal pollution in soils in Huli industrial estate in Xia’men City and near a copper mine in Shanghang,Longyan City, China. Base on the above results, In order to explore a cost-effective remediation technology for heavy metal polluted soils and search for a utilizing...学位:工学硕士院系专业:海洋与环境学院环境科学与工程系_环境工程学号:20043405
