摘　　要：以南京含镍废催化剂为研究对象,采用20:1的人造沸石和乙基黄原酸钾作为稳定化药剂进行处理,与传统的水泥固化方法进行比较,结果表明此药剂稳定化技术处理后产物中金属镍的浸出浓度满足填埋控制标准,且在较低的PH环境下更为稳定;药剂稳定化对含镍危废进行固化增容比为1:1.08,相对于水泥固化增容比1:1.53具有明显的减量化作用,可有效节省稀缺库容,更具可持续发展价值。Nanjing nickel-containing waste catalyst for the study,using potassium ethyl xanthate and synthetic zeolites as stabilizing agents for treatment with traditional cement solidification methods are compared.The results showed that this drug after stabilization techniques leaching process nickel concentration of the product in the landfill to meet control standards, and more stable at low PH environment; Pharmacy stabilized nickel-containing hazardous waste cured Capacity ratio of 1：1.08,with respect to the cement solidification Capacity ratio of 1：1.53 with a significant reduction,which can effectively save scarce capacity and have more sustainable value.
