Advanced Oxidation Remediation Technology for Semi-volatile Organic Contaminated Sites
This paper takes a polluted site in Shanghai as an example,aiming at the type of semi-volatile organic polluted site with Benzo[a]pyrene and Dibenzo[a,h]anthracene as pollution factors,adopts the advanced oxidation repair technology with ferrous activated persulfate oxidizer,and determines the optimal dosage ratio of ferrous sulfate and sodium persulfate for engineering application through laboratory and pilot tests.The organic contaminated soil excavated from the contaminated site was screened and broken,the moisture content was adjusted,and the oxidation agent was added to repair it.After the restoration,all the soil tested met the restoration requirements,and the whole restoration proces did not cause secondary pollution to the soil and groundwater of the plot.
