摘　　要：分析了钻井废水中有机污染物在土壤中吸附的机理,对吸附量和有机负荷的关系进行了阐述;针对钻井废水有机污染物在土壤中的吸附和解吸过程进行了实验研究。实验表明:钻井废水中有机污染物在土壤中的吸附量与土壤有机负荷的关系符合初始质量等温线;土壤中天然有机质含量越高,对钻井废水中有机污染物吸附能力越强;土壤对钻井废水中有机污染物具有一定的持久吸附作用;天然有机质含量越高的土壤对钻井废水中有机污染物的持久吸附能力越强。The adsorption mechanism of organic pollutants in drilling wastewater on soil was analyzed.The adsorption capacity of soil and organic pollutants load in soil as well as their relation were introduced.The experiments were studied on the absorption and desorption process of organic pollutants in drilling wastewater on soil.The experiment results showed that the relationship between adsorption capacity of soil and organic pollutants load in soil was conformed to the initial mass isotherm;the adsorption capacity of soil on organic pollutants in drilling wastewater was higher for high organic matter contents in soil;the soil showed some persistent adsorption on organic pollutants in drilling wastewater;the higher the natural organic matter contents in soil was,the better the persistent adsorption ability of soil on organic pollutants in drilling wastewater was.
