摘要
以辽河油田石油污染土壤为研究对象,利用烟煤吸附剂和褐煤吸附剂处理石油污染土壤。确定反应条件为煤质吸附剂粒径小于100μm,煤质吸附剂加入量与石油污染土壤的质量比为1∶5,反应温度60℃,搅拌强度600 r/min,搅拌60 min。在该条件下,土壤中石油的去除率达65%和70%以上。结果表明,利用煤作为吸附剂处理石油污染土壤有一定的可行性。
Taking the petroleum-contaminated soil in Liaohe Oilfield as a case,the process of treating the contaminated soil with coal adsorption and lignite were investigated.The optimum adsorption conditions were obtained as the granularity of coal adsorption of less than 100 μm,quality rate of the lignite and the petroleum-contaminated soil of 1∶5,the temperature of reaction at 60 ℃,the stirring intensity of 600 r/min for 60 min.Under this condition,the removal rate of petroleum from the soil was over 65% and 70%.The result indicated that it was feasible to some extent to treat the petroleum-contaminated soil with coal adsorption.
