| 摘 要： | 对利用重金属螯合剂处理城市垃圾焚烧飞灰的药剂稳定化工艺及处理效果进行了实验研究，并与Na2S和石灰等效果进行了比较，结果表明，该螯合剂投加量0.6%时，捕集飞灰中重金属的效率高达97%以上，为达到相同稳定化效果，螯合剂的使用量要比无机稳定化药剂少得多，同时，14个月的微生物影响实验表明，重金属螯合剂稳定化产物在填埋场环境下，其稳定性不受微生物活动的影响。

| Abstract: | Experimental study on the technological process and treatment efficiency of heavy metal chelating agent in treating fly ash from MSW incinerator, and compared with the results of inorganic chemical agents such as Na2S and lime used in treating this kind of hazardous waste have been conducted. The results indicated that the heavy metal removal rate from the treated fly ash using this chelating agent was higher than 97%, and the amount of chelating agent used was much less than that of inorganic chemical agents to reach the same stablization effect. Furthermore, the treated fly ash using this chelating agent didn' t influence by the microorganism activity in the waste column. |
