THE INFLUENCE OF ADDITIVES UPON HEAVY METALLS MIGRATION BEHAVIOR IN THE FLUIDIZED BED INCINERATION PROCESS OF SLUDGES
it has been mainly observed that the incineration temperature and additives (such as CaO and NaCl) upon the residual behavior and solidification rate of heavy metals (such as Cu
Zn
Pb
Cr
Ni and Cd) in the process of sludge incineration
to find out the migration regularity of the said heavy metals in bottom ash of incineration. Results of study show that the addition of NaCl leads the solidificatin rate of many heavy metals to decrease
explaining the increase of Cl content may hinder heavy metals to migrate into bottom ash during the course of incineration. But for Ni
the said influence isn't obvious along with the rising of temperature
the sequence of six heavy metals' solidification rate to be as follows; PbCuCrNiCdZn
this is an obvious negative correlation to their volatility.
