化学固化技术修复重金属污染土壤研究

Research on Remediation of Heavy Metal Contaminated Soil by Chemical Curing Technology

土壤重金属污染对环境和人体都有严重危害,适当的处理对土壤健康和生态安全至关重要。本文研究介绍了当前土壤重金属污染的主要来源,分析了其对环境和人体的危害,并总结了当前主要的固化药剂及其特点,最后通过试验对化学固化修复效果进行验证。试验结果表明,用复合固化剂处理Pb污染土壤,对Pb的固化率可达97.2%。

Soil heavy metal pollution is a serious hazard to the environment and the human body,and proper treatment is essential to soil health and ecological safety.This paper introduces the main sources of heavy metal pollution in the current soil,analyzes its hazards to the environment and human body,and summarizes the current main curing agents and their characteristics,and finally verifies the effect of chemical curing and remediation through experiments.The test results show that the curing rate of Pb can reach 97.2% when the Pb contaminated soil is treated with a composite curing agent.
