摘　　要：介绍了砂过滤的工作原理和过滤机理 ,建立了一套砂过滤模拟实验装置。通过多次实验取得了大量实验数椐 ,对过滤器在过滤运行时的影响因素做了详细分析 ,特别是针对降速过滤、混凝过滤及滤床饱和贮泥量的因素进行分析研究。The working principles and filtering mechanism of sand filtration are introduced. A set of experimental installation for sand filtration simulation was established. Based on the test data obtained by a series of experiments, a detailed analysis is made of the factors affecting the filter's operations, specially speed-down filtration, co-flocculation filtration and saturating capacity of stored mud on filtration bed.
