Abstract

Abstract

In this study, the effects of lactic acid fermentation broth and ultrapure water on removal of chlorine from fly ash were compared. The results suggested that 59.3% of water-insoluble chlorine in fly ash could be removed by lactic acid fermentation broth, and the ratio of fly ash entering kiln increased from 0.57% to 1.74% after treatment. Experimental results also demonstrated that the heavy metal content of fly ash after leaching by lactic acid fermentation broth was enriched. However, the heavy metal content in the fly ash residue was still lower than the limit value specified in China's national standard HJ 662—2013. Overall, replacing the water leaching with lactic acid fermentation broth leaching could be effective for the fly ash pretreatment.
