碩士 === 大葉大學 === 環境工程學系碩士班 === 101 === Heavy metal plating industry sludge generated main hazardous industrial waste in Taiwan. In this study, was sintering with iron oxide in high temperature. It explored the effectiveness of processing temperature, retention time, the amount of iron oxide added in heavy metals dissolution. Ions dissolved without significant difference for those sintering temperature below 650 ℃, retention time less than 0.5 hour. Under the premise of economizatim,the optimum sintering conditions were: 800 ℃, holding temperature for 1 hour, add an 1:1 iron,which nickel ions dissolution decreased 78% , magnesium ion dissolution decreased 80%.
