高污染河流污水静态与动态混凝沉降性能研究

Study on Static and Dynamic Coagulating Sedimentation of Sewage in High Polluted River

选取河流污水浊度79NTU,应用聚合化铝为处理污水的絮凝剂,考察污水在动态、静态条件下搅拌时间、搅拌强度、絮凝剂投加量及沉淀时间等因素对絮凝效果的影响,并设计四因素、三水平正交试验,研究了絮凝剂投加量、投加顺序及水利条件对处理污水的技术,通过对污水静态、动态混凝沉降性能效果分析。

River sewage turbidity 79 NTU, and flocculaut of poly - aluminum chloride was to treat sewage, Effects of stirring time, stirring strength and flocculallt dosage etc. under the static or dynamic state on coagulating sedimentation were analysed. Four design factors and three horizontal orthogonalities were tested. At last, the best treatment process was determined.
