摘　　要：为进一步完善土壤污染与修复课程实验教学效果,自行设计了电动技术修复操作平台,以有机玻璃反应器为模拟装置,采用稳压直流电源提供电场,并以蠕动泵为流速控制单元,研究了不同电压梯度条件下砷的去除效果。通过本综合设计实验,使学生更加直观深入地了解电动技术修复污染土壤的全过程,不仅可以加深学生对电动修复原理、土壤修复的影响因素和土壤重金属含量分析等的专业理论知识的理解,同时可以提高学生的自信心,激发出发现、探索和解决实际问题的兴趣。In order to further improve the experimental teaching effect of soil pollution and remediation course,the electrokinetic remediation operation platform was designed.Using organic a glass reactor as an analog device,the regulated dc power supply providing electric field and a peristaltic pump as the velocity control unit,the arsenic removal effect under different voltage gradient was studied.Through the comprehensive design experiment,students can get more intuitive understanding of the whole process of electrokinetic remediation,which not only can deepen students’understanding of the principle and influence factors of electrokinetic remediation and soil heavy metal content analysis,at the same time can improve the students’confidence,inspire their interesting to discover,explore and solve practical problems.
