| description | Heavy metal pollution in China’s soil is very serious, and soil remediation is urgent. At present, most of the domestic and foreign research is aimed at one soil type for soil heavy metal pollution remediation. However, the distribution of heavy metals and the effect of remediation with chemical agents are different for different soils. This study is committed to investigating the effect of WTF on the remediation of heavy metal contamination in different soils based on the existing research in the laboratory. The influence of soil quality on remediation efficiency was analyzed by TCLP leaching of heavy metals, and different forms of heavy metals were extracted from the soil using the BCR method. The experimental results showed that the soil environment was alkaline, and the response to a low addition of WTF was more obvious. The Pearson correlation coefficient analysis yielded that the increase in the organic matter content led to an increase in the oxidizable Cd content. The WTF remediation did not change the overall acidity and alkalinity of the soil so that the overall soil environment remained stable; it increased the organic matter content and added fertility to the soil, and it increased the activity of most enzymes in the soil and promoted the circulation of the soil elements, making the soil fertile. |
