摘　　要：概述高密度沉淀池的结构特点、工作原理同时进行絮凝剂PAC最佳投加量、助凝剂PAM最佳投加量、最佳污泥回流比、最佳运行负荷的工艺运行参数优化研究试验。优化结果表明该工艺对长江水源夏季高藻、冬季低温低浊度、上游来水悬浮物及泥沙含量高的突出特点具有很强的适应能力,其出水水质完全能够满足火力发电厂锅炉补给水系统水源品质要求。Structural characteristics and work theory of high density sedimentation tank were introduced. Expermental study was made on optimization parameters of high density sedimentation technique, such as the best dosage of floe- eulant PAC and coagulant PAM ,the best activated sludge reflux ratio and operating load. As optimization result show it could provide with powerful adaptability to the diversified Yangtze River water quality with high-algae in summer, low-temperature and low-turbidity in winter,large suspended solids and sediment, etc.. The effluent water quality can fully meet water quality requirements of boiler make-up water system of thermal power plant.
