摘　　要：通过絮凝动力学机理的分析,指出水流流态对混凝效果具有重要影响。设计了折板絮凝池试验模型,对不同角度的折板组合进行了研究。结果表明第1絮凝段采用90°异波折板,第2絮凝段采用90°同波波折板的组合对浊度的去除率最高,这对实际折板絮凝池的设计有很好的参考价值。By analyzing the mechanism of flocculation dynamics, it was demonstrated that flow pattern had a significant impact on flocculation effect. The model of folded plate flocculator was designed and the combinations of the folded plates with different angles were experimentally studied. The results showed that the combination of 90° opposite folded plates at the first flocculation section and 90° same wave folded plates at the second section is best of all the folded plates combinations for raw water turbidity removal, which is a useful reference to the design for actual folded plate flocculator.
