摘要
提出用恒压过滤试验法评定助滤剂的助滤效果．给出了该方法所使用的仪器装置、被过滤悬浮液、助滤剂料液的配制、操作步骤和需测定的项目．给出的几个验证实验例的结果表明该方法简便可行，利于推广．
This paper proposed the filtration characteristics of the filter aids can be evaluated by a vacuum nutsche test. The apparutus, the water sample and reagent preparation,the procedure and the pertinent variables were offered. The experiments show that this method or evaluation is simple, convenient, feasible and available.
