摘要
针对土壤污染中常见的石油烃(C_(10)-C_(40))污染因子,采用过硫酸盐/柠檬酸/Fe(Ⅱ)物质的量之比为100/10/50的配方,通过试验确定了药剂最佳添加比例为2%;土壤含水量较高时,去除效果较好;提前将水与土壤混合,将药剂溶解、加入柠檬酸均有利于提高石油烃去除效率。本小试试验为修复工程实施提供了依据,在保证修复效果的前提下,选择最优的施工工艺,既节约了药剂费用,又避免了二次污染。
According to the common petroleum hydrocarbon(C_(10)-C_(40))pollution factor in soil contamination,by using the formula of persulfate/citric acid/Fe(Ⅱ)with the molar ratio of 100/10/50,the optimum additive ratio of the reagent was determined to be 2%.When soil moisture content was higher,the removal effect was better;the removal efficiency of petroleum hydrocarbon was improved by mixing water and soil in advance,dissolving reagent and adding citric acid.The bench test provided a basis for the implementation of remediation project.Under the premise of guaranteeing the remediation effect,the optimal construction technology was selected,which could not only save the cost of the reagent,but also avoid the secondary pollution.
