摘　　要：文章在系统研究聚丙烯酰胺助滤效果的基础上,为强化微细粒煤泥的过滤脱水行为,提出了基于表面力作用的两步絮凝(剪切絮凝+高分子絮凝)技术。研究表明,两步絮凝技术能显著改善微细粒煤泥的过滤脱水效果。On the basis of systematical research on filter-aid performance of polyacrylamide,to enhance the effect of dewatering of micro-fine coal by filtration,this paper presents a two steps flocculation(shear flocculation and high molecular flocculation) technology based on the surface force effection.The research shows that the two steps flocculation technology can improve the dewatering performance of micro-fine coal slurry remarkably.
