Abstract
Incinerator fly ashes of EP (Electrostatic
Precipitator) and bottom ashes from MuCha plant
and municipal solid waste (MSW) were colandfilled
in this study. The changes of leachate
water characteristics and dissolved concentrations
of heavy metals were observed to be the reference
of disposal of only fly ashes or with bottom ashes
and MSW. The influences of mixing type that only
fly ashes, fly ashes mixing with bottom ashes and
fly ashes mixing with MSW were discussed.
From the results, the values of water quality
analyzing and the concentrations of heavy metals
were high in the initial time, and it decreased
gradually. In leachate water, the concentration of
Zn was the highest, Fe was the next, then was Cu,
Cr, Cd and Pb.
In terms of analyzing the quality of leachate
water, pH between 11~12.5 was the highest when
fly ashes mixed with bottom ashes. The
concentration of each negative ions was highest
when only fly ashes.
In terms of heavy metals of leachate water,
only fly ashes would make the concentration of
Cd and Cr higher. From leachate water that wecould find that bottom ashes decrease the
concentration of Pb and Cd in fly ashes when fly
ashes mixed with bottom ashes. The changes of
the concentration of leachate water was not
observable when fly ashes mixed with MSW, but
only the concentration of Zn has increased.
