除了一些理论上的考虑，本文还提供了实验数据，其中对明矾污泥、石灰污泥和聚合物处理的明矾污泥进行了表征。尝试将污泥特性与观察到的污泥脱水特性相关联。研究了絮体微特性（如尺寸和密度）与观察到的砂床和机械脱水装置产生的脱水特性之间的关系。当水厂污泥通过机械过滤设备处理时，絮体性质（如粒度分布和密度）对脱水速度和程度都有显著影响。聚合物的加入提高了污泥脱水率，但对滤饼固体浓度、压缩性或污泥处理特性没有显著影响。 包括15个参考文献、表格和图表。

In addition to some theoretical considerations, this article presents data from experiments in which alum sludges, a lime sludge, and polymer-conditioned alum sludges were characterized. An attempt was made to correlate the sludge characteristics with observed sludge dewatering characteristics. Relationships between floc microproperties, such as size and density, and observed dewatering characteristics produced by sand bed and mechanical dewatering devices are examined. Floc properties such as size distribution and density showed a significant effect on both the rate and extent of dewatering obtained when water plant sludges were treated by mechanical filtration equipment. Polymer addition improved sludge dewatering rates but did not significantly affect cake solids concentrations, compressibility, or sludge handling characteristics. Includes 15 references, tables, figures.
