用煤矸石制备 PAFS 及处理洗煤废水试验研究
Preparation of PAFS Using Coal Gangue and Treatment of Coal-Washing Wastewater
摘要
Abstract
The preparation of polymeric aluminum ferric sulfate (PAFS ) using coal gangue and treatment of coal‐washing wastewater were researched .The influence of iron to aluminum ratio , system pH ,polymerization temperature and polymerization time on turbidity removal character of the PAFS were examined .The optimum conditions for preparation of PAFS were determined:c(Al3+ +Fe3+ )=0 .6 mol/L ,ratio of iron to aluminum is 10∶3 ,system pH=0 .8 ,polymerization temperature is 60 ℃ ,polymerization time is 7 h ,and aging time at room temperature is 24 h .Finally ,the coal‐washing wastewater is treated by the prepared PAFS under the optimum conditions ,and the proper conditions are pH of 8 .0 ,the 5% PAFS addition amount of 6 mL for 800 mL wastewater .The wastewater residual turbidity deduces to low er than 20% .关键词
