Created the urban structure of the node, forming the urban rail transit-dependent and lifestyle, as well as mass transit systems provide adequate passenger protection. 5.1.3 to guide the healthy development of 选择合适的有机溶剂比如甲醚等，实现表面活性剂与疏水性难溶有机物的分离。由于表面活性剂具有亲水性，有机难溶污染物具有疏水性，因此，甲醚可将有机难溶污染物萃取到有机相中，而表面活性剂留在水相中如图2所示。因此，表面活性剂溶液可以连续循环使用。这可大大降低操作成本。 图2. 表面活性剂的萃取回收 (3)有机污染物的氧化降解 难溶污染物被萃取到有机相后，将溶剂蒸发然后留下有机污染物，加入Fenton氧化剂、通入臭氧或者其它氧化剂，将其氧化成无毒的二氧化碳和水，实现彻底的净化。 2、可行性和风险分析 正如前面所述，重污染场地实际上是高浓度难溶性有机污染物包埋在土壤中。用表面活性剂所形成的胶束进行溶解和淋洗是完全可行的，而且这一技术在国际上已经有人进行了相关研究和应用。因此，本项目没有任何风险。潜在的风险，比如人工合成表面活性剂在应用时可能会残留，我们通过使用生物表面活性剂加以克服。鼠李糖脂生物表面活性剂有商业化的生产，并广泛应用于石油的开采，没有二次污染的问题。 四、预期成果 预期达到的目标是，主要有机物在土壤中的残留量达到民用建筑对土壤环境质量的要求。其参考标准(目前国家还没有民用建筑土壤环境质量标准，因此，layout development cities in developed countries show that developing rail transit Guide and an important means of achieving sustainable urban development.
