Abstract

Abstract

The remediation techniques of benzene, 1, 4-dichlorobenzene, and 1, 2-dichlorobenzene in soil with high pollution level (>120 mg/kg) and low pollution level (<25 mg/kg) were used to study the remediation of soil contaminated by typical pesticide production sites. The results showed that the removal of benzene, 1, 4-dichlorobenzene, and 1, 2-dichlorobenzene from contaminated soil was significantly affected by normal temperature desorption (quicklime+mechanical stirring), chemical oxidation (alkali activated sodium persulfate) and thermal desorption (200~400 ℃), but the effect of different remediation techniques was significantly different. Normal temperature desorption technology and alkali activated sodium persulfate oxidation technology could not fully meet the remediation requirements under experimental conditions, while thermal desorption technology (optimal conditions: temperature of 400 ℃, residence time of 20 min) could meet the remediation standards for the three target pollutants in soil with low and high pollution levels.
- chemical oxidation,
- desorption at room temperature,
- thermal desorption,
- volatile organic compounds(VOCs),
- soil remediation
