【摘要】 采用烘干法对原油污染壤黏土、原油污染砂土、柴油污染壤黏土和柴油污染砂土的含水率进行了校正.结果发现,烘干过程中石油和水分的挥发互不影响,每种油品挥发损失比例固定.通过含水率与含湿率之间的关系,提出了试验用石油污染土壤含水率的校正公式.更多还原

【Abstract】 The experiment was carried out to calculate and revise the water content of four oil-contaminated soil samples(crude oil-contaminated loamy clay,crude oil-contaminated sand,diesel oil-contaminated loamy clay,diesel oil-contaminated sand) by oven dry method.It was found that oil and water volatilization was independently with each other,and the volatizing loss of oil was a fixed ratio in the drying process.Through the relationship between water content and moisture content,the correction formula of water content in the oil-contaminated soil was put forward.更多还原
