摘　　要：研究了沿面放电和平板介质阻挡放电处理土壤中阿特拉津和乙草胺的效果。主要以沙子作为研究体系,考察了水分、氧气流速、活性炭和过硫酸钠对降解的影响。结果表明:沿面放电装置和平板介质阻挡放电都能高效降解沙子中的乙草胺、阿特拉津;水分和氧气流速对降解的影响较大,在一定限度内,它们的增加能迅速提高降解效果,但过多的水分反而会抑制污染物的降解。活性炭显著抑制沿面放电降解乙草胺和阿特拉津效果,过硫酸钠与沿面放电、平板介质阻挡放电联用方法没有表现出协同效应。The creeping discharge and planar dielectric barrier discharge were used to treat the soil contaminated by the herbicides. The effects of the moisture,oxygen flow rate,active carbon and sodium persulfate on the degradation of acetochlor and atrazine in soil were investigated. Results showed that two kinds of low-temperature plasma technologies were effective in the degradation of acetochlor and atrazine in sand. Activated carbon could significantly inhibit degradation of acetochlor and atrazine using creeping discharge,the combination of sodium persulfate and creeping discharge did not show a synergistic effect.
