本文提出了一种评估通过深层过滤从水中去除颗粒物的各种模式的方法。基于反洗动力学，该方法考虑了与颗粒附着（有无明矾处理）、颗粒团聚和颗粒分离相关的机制。实验包括在砂、玻璃和无烟煤滤床上进行的试验。使用了三种过滤粒度和两种过滤速率。向高岭石悬浮液中添加几剂明矾，以产生具有不同大小和zeta电位的悬浮颗粒。数据表明，在凝聚体形成过程中作用的附着力取决于大小，而不是zeta电位。 包括6个参考文献、表格、图表。

This paper presents a method for evaluating the various modes involved in particle removal from water by means of deep-bed filtration. Based on backwashing kinetics, this method takes into account the mechanisms associated with particle attachment (with and without alum treatment), particle agglomeration, and particle detachment. Experiments consisted of tests carried out on filter beds of sand, glass, and anthracite. Three filter grain sizes and two filtration rates were used. Several alum doses were added to a kaolinite suspension to produce suspended particles with different sizes and zeta potentials. Data indicate that the attachment force acting during formation of an agglomerate depends on size rather than zeta potential. Includes 6 references, tables, figures.
