利用正交试验设计,选用市售腐植酸钠、自制腐植酸钠和碱水作为洗涤剂,在不同温度和洗涤次数的条件下对落地原油中度污染的土壤进行洗涤,分析洗涤剂种类、洗涤温度和洗涤次数3个因素对洗涤效果的影响。结果表明：洗涤次数对洗涤效果影响最为显著,洗涤剂种类次之,洗涤温度影响最小。试验最优方案为选用市售腐植酸钠,在60℃下洗涤3次（即A3B1C3）。

Self-made sodium humate, sodium hydroxide and commercial sodium humate were taken as the detergents to wash aeolian sandy soil polluted by crude oil. The orthogonal experiment was designed to obtain the optimal tern- perature, washing times and detergent types. The results showed that the most significant factor was washing times, the second one was detergent type, and the effect of wash temperature was the smallest. The best technics was using commercial sodium humate as detergent to wash polluted soil for 3 times under the condition of 60℃.
