摘要
土壤淋洗是指将淋洗剂注入到受重金属等污染的土壤中,使污染物溶解或迁移到液相,进而降低被污染土壤有害毒性的一种方法。现一般将土壤淋洗剂分为无机淋洗剂、螯合剂、表面活性剂和复合淋洗剂四种,根据淋洗剂的不同和淋洗环境的不同,淋洗效果也各有不同。
Soil washing is a technology that injects a liquid medium as the washing solution into heavy metal contaminated soil to dissolve or remove the pollutants for further wastewater treatment, so as to reduce the harmful and toxic contaminants in the soil. Currently, there are four common types of washing reagents including inorganic solvents, chelating agents, surfactants, and compound agents. According to the different washing agents and washing environment, the effect is also different.
