摘要
本研究针对重金属钒、锰污染土壤开展淋洗修复技术实验。通过筛选淋洗剂、优化淋洗条件,探讨了淋洗修复技术的可行性。本次实验分别对淋洗剂种类、浓度、固液比及淋洗时间进行了筛选,结果表明最佳淋洗剂为柠檬酸,最佳淋洗固液比为1∶5,最佳淋洗浓度为0.5 mol/L,最佳淋洗时间为4 h。该研究结果为重金属钒、锰污染土壤的修复提供了理论依据和技术支持。
This study conducted a small-scale experiment on the soil contaminated by heavy metals vanadium and manganese using the leaching remediation technology.By screening leaching agents and optimizing leaching conditions,the feasibility of the leaching remediation technology was explored.Through the screening experiments of leaching agent types,concentrations,solid-liquid ratios,time and application frequency,the experimental results showed that the best leaching agent was citric acid,the optimal leaching solid-liquid ratio was 1∶5,the optimal leaching concentration was 0.5 mol/L,the optimal leaching time was 4 hours.The research results provided theoretical basis and technical support for the remediation of heavy metal contaminated soil.
