摘　　要：采用浊度检测和颗粒计数技术评价了高锰酸盐复合剂预氧化工艺对滤后水中颗粒物的去除效果。结果表明,PPC预氧化能有效地强化滤后水中颗粒物去除效果,使颗粒总数降低幅度达65.0%,采用浊度指标不能有效地反映滤后水质的变化,将浊度检测与颗粒计数技术相结合,能更有效地反映滤池对颗粒物质的去除效果。Abstract： Both turbidity monitoring and particle countirig technique are applied to evaluate particle removal effect of filtered water within full ranges of particle size by potassium permanganate composite preoxidation process in pilot scale. The results show that the particle removal effect of filtered water can be enhanced effec- tively by preoxidation of potassium permanganate composite. The reduction of total particle number is reached 65.0 % ~ The quality variations of filtered water can not be indicated by index of turbidity. The removal per- formances of particle matters of filter are indicated effectively by the combined application of turbidity and particle counting technique.
