碩士 === 淡江大學 === 水資源及環境工程所 === 82 === Currently in Taiwan,large scale incinerators are under cons-
truction one after another.Inorganic ones are concentrated on
the fly and bottom ashes.The heavy metals of residuals
contained or released excessively in amount tend to
untowardly environments. The study is devided into two parts:
column test and shake test.The former were followed Jou''s study,
its items under the probe include the leachate analysis on
different height,different lifts and different pH values of
precipitation condition on land -fills.The latter one studied
the influence of chloride in leach- ate ashes on the
dissolution of heavy metals. The results indicated that in
terms of distilled water extra- ction test the dissolution of
heavy metals became lower after long-time storged.In different
landfill condition,the cumulativly released quantity of copper,
cadmium,lead and zinc were inverse proportion to the height of
landfill.If incinerator residual were buried in separate lifts
at different time,although it would be helpless to stabilize
leachate quality,it could reduce the peak release concentration
especially for chloride and copper.In terms of simulative
precipitation of varied pH values,the precipitation with pH=7.0
leached the heigh copper,cadmium,lead and zinc peak
concentration andcumulative quantity of copper. In terms of
dissolution of heavy metals contained in fly and combined ashes
by different concentration of chloride.The cmulat- ive release
quantity of cadmium and lead were indirect proportion of
concentration of chloride.It indicated that effect of complex-
ing andactually released guantity of each heavy metals formd
complexes with chloride were extensively.
