【 摘 要 】

This paper mainly studied the stabilization effect of lead in flue dust on different stabilizers. The leaching concentration and fraction distribution of flue dust under different stabilizers were studied by TCLP and BCR continuous extraction. Experimental results showed that each stabilizer has a different effect on the leaching of heavy metals in flue dust. After phosphate stabilization or phosphate plus calcium source stabilization, the leaching concentration of Pb decreased considerably, and Pb was mainly transformed to residual state. Therefore, it achieved the stable effect for heavy metals.
