摘要
以国内某焦化企业场地多环芳烃污染土壤为研究对象,研究了过硫酸钠作为氧化剂时,硫酸亚铁或次氯酸钠助剂的使用对修复效率的影响,同时通过对比阐述了硫酸亚铁及次氯酸钠在过硫酸钠氧化体系中的不同作用。结果表明:微量硫酸亚铁对过硫酸钠氧化土壤中多环芳烃起到催化作用,可显著提高多环芳烃去除效率;次氯酸钠可与过硫酸钠协同使用,达到共氧化的目的。
The effects of additives,FeSO4 and NaClO,on the chemical oxidation treatment efficiency of soils contaminated by polycyclic aromatic hydrocarbons using Na2S2O8 as oxidant were investigated .The different roles of the additives were compared.Results showed that removal efficiency of PAHs was enhanced by addition of little FeSO4 as catalysts in NaS2O8 system.NaS2O8 and NaClO could be used in coordination with sodium persulfate to achieve the purpose of cooxidation.It is concluded that the test results can provide some references for the selection of site restoration technology and chemical oxidation process design.
