| 摘 要： | 持久性有机污染场地土壤淋洗法是污染场地土壤物化修复方法中一种常用的技术。淋洗法是指运用特定淋洗剂对污染土壤进行深度洗涤,通过分离净化淋洗剂,实现回用集成,达到去除土壤中污染物的目的,并最终安全化处置污染物和修复土壤的过程。本文根据污染场地土壤处理位置、淋洗剂种类和淋洗剂施用方式的差异,将持久性有机污染场地土壤淋洗法划分为不同的种类;总结了为达到高效去除土壤中污染物质,可运用多级淋洗方式、超声方式、电动力方式和化学氧化等方式实现强化修复效率;阐述了污染场地土壤质地、污染物性质、淋洗剂性质、淋洗条件优化以及淋洗剂回用效率等因素对淋洗修复整体效用的显著影响;同时指出了目前持久性有机污染场地土壤淋洗法存在的问题和今后国内外研究和应用的方向。综合考虑土壤淋洗修复技术适用范围和成本因素,认为淋洗法是一种较符合我国持久性有机污染场地土壤实情的修复技术,具有较强的针对性和较广泛的运用前景。

| Abstract: | Soil washing process is one of the most used physical and chemical methods in the remediation of POPs contaminated sites. Soil washing process floods contaminated soil with special washing solution that flushed out contaminants to a place where they are removed and the washing solution must be recycled and reused, also the spent washing solution and washed soils must be treated further, then could the aims of contaminated soils remediation be achieved. Soil washing could be classified into many types according to different disposal positions, types of washing solutions and mixing washing solvents. Enhanced removal efficiency could be achieved through methods of treatment styles, ultrasound, electokinetics, chemical oxidation and so on. The removal efficiency of soil washing process is remarkably affected by many factors such as soil texture, contaminant characters, washing solution characters, optimum running conditions for soil washing operation and reuse efficiency of washing solution. Problems and technical difficulties in soil washing process and the prospect of further research and application are also presented. Considering the scope of application of soil washing and cost factors, soil washing is a suitable technology in line with actual status of POPs contaminated sites in China, it may have a wider application prospects. |
