摘要
对用赤泥为原料制备水处理用复合混凝剂的条件进行了较详细的研究 ,包括酸浸时酸的浓度、浸出时的液固比、浸出温度及时间 ;活化时的碳酸镁用量、活化pH值、活化温度和时间 ,确定了用赤泥制备复合混凝剂的的最佳工艺条件 。
The conditons of the preparation of a compound coagulant using red mud as a raw material were investigated in detail.The preparation process included acid leaching stage and activation process.The factors influencing the acid leaching included the acid concentration,ratio of liquid to solid,temperature and time.The factors influencing the activation process included the dosage of magnesium carbonate,pH,temperature and activation time.The best conditions for preparing the compound coagulant from red mud were determined.
