METHOD FOR TREATING FLYING-ASH LEACHATE

摘要

PROBLEM TO BE SOLVED: To provide a method for treating flying-ash leachate which can efficiently reduce Pb components in a liquid after solid-liquid separation. SOLUTION: This method for treating flying-ash leachate includes a process 21 of precipitating Pb components dissolved in the leachate by a coprecipitation effect with heavy metal salts by adding a heavy metal containing solution 17 dissolving heavy metals to the flying-ash leachate 12 dissolving Pb components and a process 22 of solid-liquid separation of coprecipitated precipitates 24.
