摘要
本研究旨在分析不同化工重金属污染土壤修复技术的实施效果,并结合现场监测数据进行评估。通过对比实验组和对照组的修复数据,采用物理、化学及生物修复技术进行现场仿真模拟,评估修复前后的重金属浓度、土壤酸碱度、植物吸收率和微生物活性等指标变化。实验结果表明实验组的重金属浓度显著降低,植物吸收率和微生物活性显著提高,土壤酸碱度逐步向中性转化。150 d内,重金属含量从100 mg/kg降至15 mg/kg,植物吸收率达到85%,微生物活性提升至0.18,显示出修复技术的显著效果。研究结果表明综合修复方法能有效提升土壤质量降低重金属污染,具有较好的工程应用前景。
This study aims to analyze the implementation effects of different remediation technologies for heavy metal-contaminated soil in the chemical industry and evaluate them based on field monitoring data.By comparing remediation data between experimental and control groups,physical,chemical,and biological remediation technologies were applied in on-site simulation to assess changes in indicators such as heavy metal concentration,soil pH,plant uptake rate,and microbial activity before and after remediation.The experimental results showed that the heavy metal concentration in the experimental group significantly decreased,while plant uptake rates and microbial activity significantly increased,with soil pH gradually shifting toward neutrality.Within 150 days,the heavy metal content dropped from 100 mg/kg to 15 mg/kg,the plant uptake rate reached 85%,and microbial activity increased to 0.18,demonstrating the remarkable effectiveness of the remediation technologies.The findings indicate that integrated remediation methods can effectively improve soil quality and reduce heavy metal pollution,offering promising prospects for engineering applications.
