【摘要】 异位稳定化技术处理重金属污染土壤在国内外已有应用,但鲜有大规模工程应用时的控制关键及操作要求的报道。本研究根据异位稳定化处理技术的特点,采用该技术处理重金属复合污染且修复时间有限的目标污染场地,通过合理控制稳定剂投加量、土壤理化性质、施工工艺及养护条件等各项影响因素,取得了很好的处理效果,可为类似污染场地提供借鉴和经验。更多还原

【Abstract】 Ex-situ stabilization technology has been applied for remedying sites contaminated with heavy metals abroad or in China.But there’s few reports on how to control key parameters while practising large-scale remedy project with this technology.The site needed remedy here was multi-contaminated with seven kinds of heavy metals.But the time acceptable for remedy was very limited due to its own characteristics,ex-situ stabilization technology was adopted.Through controlling dosage of stabilizer,physical and chemical properties of soil,operation methods,curing conditions,as well as other influencing factors,it was obtained excellent treatment results.Which could provide good experiences for similar sites.更多还原
