摘　　要：当下,镉(Cd)、铅(Pb)、锌(Zn)等为主的重金属污染日益严,极大危害了工农业发展和人民生命健康。复合重金属离子污染是工农业生产中主要的污染形式,针对复合重金属污染土修复的研究具备现实意义。此外,醋酸用于修复复合重金属污染高岭土的相关研究相对较少,其内在修复机理和反应机制尚待阐明。有鉴于此,以室内模拟的镉铅锌复合污染高岭土作为研究对象,采用电动修复技术并使用不同浓度醋酸溶液对复合重金属污染高岭土进行修复,结合多种测试方法,通过对电渗流、pH、电导率、重金属离子残留量和电流变化进行分析,深入探究电动修复过程的污染土内在修复机理。At present,heavy metal pollution mainly composed of cadmium(Cd),lead(Pb),zinc(Zn),etc.is becoming increasingly severe,which greatly endangers the development of industry and agriculture and the health of people’s lives.Composite heavy metal ion pollution is the main form of pollution in industrial and agricultural production,and research on the remediation of composite heavy metal contaminated soil has practical significance.In addition,there is relatively little research on the use of acetic acid for the remediation of composite heavy metal contaminated kaolin,and its intrinsic remediation mechanism and reaction mechanism still need to be elucidated.In view of this,taking indoor simulated cadmium lead zinc composite polluted kaolin as the research object,electric remediation technology was adopted and different concentrations of acetic acid solution were used to remediate the composite heavy metal polluted kaolin.Combined with various testing methods,the internal remediation mechanism of polluted soil in the electric remediation process was deeply explored by analyzing the changes in electroosmotic flow,pH,conductivity,residual heavy metal ion and current.
