Example Embodiment
[0046] Example 1: Remediation treatment of soil contaminated by BHC pesticide.
[0047] In Example 1, the method provided by the invention was used to perform chemical oxidation remediation treatment on the contaminated soil in a certain site. The initial concentrations of α-BHC and γ-BHC in the soil were 1360mg / kg and 1620mg / kg, respectively.
[0048] In this soil remediation treatment, component B and component A were added in the form of dry powder to the contaminated soil and mixed thoroughly, and then water was added to adjust the soil moisture content and maintained for 5 days. In this example, in order to detect the synergistic oxidation effect of surfactants at different doses, the sodium dodecyl sulfate (SDS) in component B was compared with 0%, 1%, 2.5%, and 5% of the soil mass. Add. The grouping arrangement of the medicine is shown in Table 1.
