混合絮凝剂对赤泥沉降效果的探讨

Discussion about the effect of mixed flocculants on settling performance of red mud

研究发现,当聚丙烯酰胺类A型絮凝剂和氧肟酸类H3型絮凝剂按合适的比例混合使用时,赤泥沉降沉速提高,上清液浮游物显著降低。而且,混合絮凝剂的添加量比单一絮凝剂的也要低。

It is found that when A - floceulant containing polyaerylamide and H3 - floeeulant containing hydroxamic acid are used together at the proper rate , then the settling rate of red mud is increased and the suspended solid decrease. It is shown that, the level of addition of mixed flocculants is lower than single floceulants.
