摘要
文章以上海市某污染场地为案例,针对污染因子为苯并[a]芘、二苯并[a,h]蒽的半挥发性有机污染场地类型,采用以亚铁激活过硫酸盐类氧化剂的高级氧化修复技术手段,通过实验室小试和中试试验确定工程应用硫酸亚铁和过硫酸钠的最佳药剂投加比例,对污染场地中清挖出有机污染土壤进行筛分破碎、调节含水率、添加氧化药剂进行修复.修复后的土壤经过检测均达到修复要求,且整个修复过程未对地块的土壤和地下水造成二次污染.
Abstract
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.
