영문 초록

This study was conducted to recover the aluminum from water treatment plant sludge containing alumina. The optimum reaction conditions about chlorination of sludge with NH₄Cl are as follows: the weight ratio of sludge to NH₄Cl is 4, the reaction time is 60min, and the temperature is 300℃. And the result of leaching time test showed that the highest yield of alumina at 160℃ was 96% but the result of leaching test at 160℃ was little better than that of leaching test at 100℃ while the leaching concentration of HCl was 4N. The optimum reaction conditions of chlorinated sludge with NH₄Cl, gave the highest yield of 95.41% based on aluminum.
