摘要
以原油污染的砂土为试验对象,研究市售腐植酸、自制腐植酸钠和碱水在不同洗涤次数和洗涤温度条件下,淋洗除去原油的效果。试验结果表明,整体上,各因素对砂土平均除油率的显著性依次为洗涤剂>洗涤次数>温度,其中洗涤剂种类和洗涤次数对清洗土壤的平均除油率影响都达到显著水平。从洗涤剂单一因素来看,3种洗涤剂对污染土样都有一定的洗涤效果,但除油率相差不大,自制的腐植酸钠、碱水和市售腐植酸的最大除油率分别是21.83%、24.89%、22.28%。
The sandy soil samples that are moderately contaminated by ground crude oil are washed under different temperature, washing times and different reagents in this paper. The results show that the most effective washing order for removing the residual crude oil is reagents〉washing times〉temperature on the whole. All three reagents can wash crude oil out, but the removal efficiency is not considerably different. Alkaline solution, humic acid and self-made sodium humate reach their maximum removal efficiency which are separately 24.89%, 22.28% and 21.83%.
