摘要
选取土壤中的含油数量、土与水之比、土壤的类别、以及超声处理的时间和功率等5个因素做了正交实验,反映了之间的相互作用,并分析了其中的各因素,即在土壤中清除石油污染物的效率。而土壤的类型影响净化效果很明显,从粘土与砂土比较,前者的TPH的清除率比较高。通过研究表明,充分利用超声波技术去修复石油污染的土壤,拥有广泛的发展前景。
Taking oil content in soil, ratio of soil and water, soil category, ultrasonic processing time and power as five factors for the orthogonal experiment, the interaction between them was analyzed, and effect of the various factors on the removal efficiency of oil pollutants in the soil was investigated. The results show that the type of soil can affect the purification effect obviously; TPH clearance rate of the clay is higher than that of sand.
