研究了混凝机理（受混凝剂用量、进水浊度和混凝pH值的影响）对氢氧化铝和氢氧化铁污泥浓缩和脱水特性的影响。随着混凝pH值或混凝剂用量的降低或进水浊度的增加，污泥浓缩和脱水得到改善。啮合混凝产生了含水量高的大絮体，导致脱水过程中的除水效果差。吸附电荷中和混凝产生的絮体较小，但密度大得多，这与污泥中的水去除率较高相对应。包括13个参考文献、表格、图表。

The effects of coagulation mechanism (as influenced by coagulant dosage, influent turbidity, and coagulation pH) on the thickening and dewatering characteristics of aluminum and ferric hydroxide sludges were examined. Sludge thickening and dewatering improved with a reduction in coagulation pH or coagulant dosage or with an increase in influent turbidity. Enmeshment coagulation produced a large floc with a high water content, resulting in poor water removal during dewatering. Adsorption-charge neutralization coagulation yielded a smaller but much denser floc, which corresponded to greater water removal from the sludge. Includes 13 references, tables, figures.
