Research on Thermal Treatment Process of Organic Heavy Metal Composite Polluted Soil
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.
