摘　　要：为提升有机物与重金属复合污染土壤的修复效果,采用热处置技术进行实验探索。通过设定不同的加热温度、时间,以特定的工业污染土壤样品为例,系统地研究热处理对土壤中pH值、有机物浓度、重金属赋存形态和土壤理化性质的影响。实验采用土壤样品分析与多种仪器检测方法,对比热处理前后土壤的变化情况。结果表明,对土壤进行适当的热处理,可降低土壤中有机物的浓度,还能减少重金属的生物有效性,改善土壤的理化性质,为修复复合污染土壤环境提供了一种技术方案。In order to improve the remediation effect of soil contaminated with organic matter and heavy metals,thermal treatment technology was used for experimental exploration.By setting different heating temperatures and times,taking specific industrial polluted soil samples as examples,the effects of heat treatment on soil pH value,organic matter concentration,heavy metal occurrence forms,and soil physicochemical properties were systematically studied.The experiment used soil sample analysis and various instrument detection methods to compare the changes in soil before and after heat treatment.The results indicate that appropriate heat treatment of soil can reduce the concentration of organic matter in soil,decrease the bioavailability of heavy metals,improve the physical and chemical properties of soil,and provide a technical solution for the remediation of complex polluted soil environment.
