重金属污染土壤修复技术及其修复实践研究

Research on Remediation Technology and Practice of Heavy Metal Polluted Soil

为解决重金属污染土壤带来的环境问题,对比分析重金属含量变化、土壤p H值变化、植物生长情况、土壤微生物群落变化等关键指标,结果表明,综合应用多种修复技术可显著提高土壤修复效率,降低重金属含量,改善土壤生态环境。此外,修复效果与土壤初始性质密切相关,且不同修复技术对土壤环境的长期影响存在显著差异。研究发现可为实际的重金属污染土壤修复工作提供了重要的科学依据。

In order to solve the environmental problems caused by heavy metal pollution in soil,key indicators such as changes in heavy metal content,soil pH value,plant growth,and soil microbial community were compared and analyzed.The results showed that the comprehensive application of multiple remediation technologies can significantly improve soil remediation efficiency,reduce heavy metal content,and improve soil ecological environment.In addition,the remediation effect is closely related to the initial properties of the soil,and there are significant differences in the long-term impact of different remediation techniques on the soil environment.The research findings provide important scientific basis for the practical remediation of heavy metal contaminated soil.
