| 摘 要： | 研究快速搅拌强度(GR)、快速搅拌时间、缓速搅拌时间以及pH等因素对低温低浊水混 凝沉淀效果的影响。研究结果表明,当混凝剂投加量一定时,选择合适的混凝条件,沉后水浊度、沉 后水中混凝剂残余量及过滤阻抗系数STI将有较大改善。并且伴随快速搅拌强度的增大,与沉后水 浊度相比,混凝剂残余量及过滤阻抗系数改善更加显著。

| Abstract: | The influencing factors on coagulating precipitation process treating low temperature and low turbidity raw water, including the strength and time of rapid agitation, the time of slow agitation and the pH are investigated. The results indicated that at selected suitable coagulation conditions and certain coagulant dosage, some key parameters of the precipitated water such as the turbidity, the coagulant residue and the filter impedance index STI (Suction Time Index) would be improved to a great degree. With the increasing of rapid agitate strength, coagulant residue and filter impedance index STI of the precipitated water would improve more remarkably than turbidity. |
