煤矸石酸浸液制备聚硫酸铝铁的试验研究
Preparation of PAFS Using Acid Leaching Solution of Coal Gangue
摘要
Abstract
Using Liupanshui coal gangue as main raw materials ,the polyaluminum-ferricsulfate (PAFS) was prepared ,and the PAFS was used to treat kaolin-containing simulation wastewater .Adding 0 .5 mL PAFS solution (10 g/L ) in the 800mL kaolin-containing simulation wastewater ,settling for 30 min ,the effects of Fe/Al molar ratio ,polymerization temperature ,polymerization time and aging time on the turbidity-removing ability of PAFS were investigated .The results show that the removal rate of the wastewater turbidity is over 98% when pH is 0 .8 ,Fe/Al molar ratio is 0 .5 ,polymerization temperature and time is 80 ℃ and 6 h ,aging conditions are room temperature and 24 h .关键词
