【摘要】 <正>基于本实验室TOC/AA对土壤石油污染五级划分和污染程度判定[1],在土壤铁测定含量基础上,对石油污染土壤进行超声、芬顿及类芬顿的单独和/或联合清洗。着重探讨了土壤石油污染等级与清洗效率的关系。结论(表1):(1)在8种清洗方法中,对于I级污染的土壤,超声-芬顿-超声先后清洗的效率最高,能将其污染等级降为Ⅲ级;对于II、III级污染的土壤,芬顿法单独清洗的效率最高,清洗后土壤污染等级更多还原

【Abstract】 Based on the petroleum pollution classification, five-level standard of TOC/AA our lab built before, briefly from I, II to V levels [1], and also the determination of Fe content of the contaminated soils, this paper specifically chooses the Ultrasonic, Fenton and/or Fenton-like methods independently or jointly for pollution remediation. It is emphasized on the relationship between the five-level standard of oil-contaminated soil and the treatment efficiencies of ultrasonic, Fenton and Fenton-like methods. Conclusion as follows(Table 1):(1). Among all 8 methods to the I level, the Ultrasonic- Fenton- Ultrasonic method has the highest efficiency with the degradation of the I level to the level III. For the soil of II and III levels, the efficiency of Fenton treatment independently is the highest with the degradation to the level IV. For the V level soil, however, Fenton-like method account the highest cleaning efficiency, but only of 23%.(2)The pollution levels of oil-contaminated soils have great effects on the all treatment methods, with the higher of the pollution level(more serious pollution), the better of the degradation efficiency. Suggestion, let pollution less than III level be bioremediation.更多还原
