  • 摘要: 采用加酸浸出工艺对垃圾焚烧飞灰进行无害化处理。研究证明盐酸能有效分离飞灰中重金属，重金属浸出率与盐酸浓度及液固比有关；重金属在实验的盐酸浓度和液固比下都能达到高浸出率，但液固比越低，浸出液中重金属的浓度就越高，越有利于重金属的回收。当盐酸浓度为5 mol·L-1、液固比为2（mL:g）时，Pb、Cd和Zn浸出率均达到95%以上，而Cu的浸出率也达到81.38%，Pb、Cd、Zn和Cu的浓度分别为468.10、78.12、2 268.80和347.78 mg·L-1。残灰采用加盐水洗工艺后，浸出毒性超标的重金属Pb和Cd浸出毒性低于GB 16889-2008标准限值，符合填埋要求。
    Abstract: A effective method of acid leaching for waste incineration fly ash harmless was applied in this study. Hydrochloric acid leaching was shown to be a more effective approach than sulfuric leaching and nitric acids leaching for heave metal separation from fly ash. Concentration of hydrochloric acid and solid/liquid ratio were the major factors influenced the heavy metal leaching, and a higher hydrochloric acid concentration and solid/liquid ratio can contribute to the enhancement of heavy metal leaching. The concentration of Pb, Cd, Zn and Cu in leachate was 468.10, 78.12, 2 268.80 and 347.78 mg·L-1 with the leaching rate of 99.30%, 99.03%, 97.75% and 81.38%, respectively, by using hydrochloric acid of 5 mol·L-1 and under the solid/liquid ratio of 2 (mL:g). The concentrations of heavy metals in residual ash were below the minimum requirements of the China national standard for landfill (GB 16889-2008).
