摘要
采用自主研发的以氨基羧酸盐为主的有机复合药剂处理上海2座生活垃圾焚烧厂的飞灰,对原灰和稳定化飞灰分别进行元素化学形态测试,结果表明:复合药剂对飞灰中Pb元素的稳定化效果最好,其易浸出态比例从29.60%、27.49%下降到3.05%、0.29%,稳定化飞灰的浸出毒性达到GB 16889—2008限值要求,可以进入生活垃圾卫生填埋场单独填埋。
The fly ash from two municipal solid waste incineration plants in Shanghai was treated by self-developed organic composite chelating agents. The results indicated that the stabilization effect of Pb was the best,and the easy-leaching ratio decreased from 29.60% and 27.49% to 3.05% and 0.29%. The leaching toxicity of stable fly ash reached the limit of GB 16889-2008,which can be entered into the separate area in municipal solid waste landfill site.
