阐述了处理“双流法”溶出赤泥不同絮凝剂的添加方法，分析了其产生结果的原因。并在试验室和半工业试验（１２ｍ３／ｈ）中考察了赤泥的沉降速度和溢流澄清度。 The method of adding different flocculants for the treatment of “two-flow method” dissolution red mud was expounded, and the reasons for its production were analyzed. The settling velocity and overflow clarity of the red mud were investigated in laboratory and semi-industrial tests (12 m 3 / h).
