表面活性剂在拜耳赤泥过滤中的应用

主要针对赤泥过滤时，添加适宜的表面活性剂，使拜耳赤泥料浆中的液体表面张力下降，从而达到降低过滤后拜耳赤泥浆含水率的目的。文中详细阐述了根据拜耳赤泥的特性，筛选拜耳赤泥过滤适应的表面活性剂，并深入地分析了三种类型的表面活性剂在拜耳赤泥过滤的作用和影响，提出了在拜耳赤泥过滤方面采用阴离子表面活性剂的研究方向。

APPLICATION OF SURFACE ACTIVE AGENT IN BAEYER RED MUD FILTRATION

The suitable surface active agent was added to decrease the liquor surface tension of Baeyer red mud slurry so as to achieve the aim of decreasing mud moisture content after the filtration. Suitable surface active agent were screened according to the character of Baeye red mud,the paper analyzed the function and effects of three type surface active agent on Baeyer red mudfiltra-tion,and stated study direction of adding anionic surface active agent for Baeyer red mud filtration.
