Analysis of the Effect of Soil Remediation Processes Contaminated by Heavy Metals in Different Soils

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