| 摘 要： | 以不同浊度高岭土水样为研究对象,运用激光光散射法对氢氧化镁混凝剂絮体开始形成时间和氯化镁最小投加量进行测定,探讨了氯化镁投加量对沉后出水浊度和Zeta电位的影响.结果表明:(1)氢氧化镁混凝剂絮体开始形成时间随着氯化镁投加量的增大而缩短;pH增大及浊度增大时,絮体开始形成时间总体缩短,pH=11.5、氯化镁投加量为25...

| Abstract: | Laser method was applied to determine the floc formation time of magnesium hydroxide coagulant and the minimum coagulation dosage in different turbidity of kaolin water samples.The effects of coagulant dosing quantity on effluent turbidity and Zeta potential were also discussed.The results showed that the floc formation time was decreased with increasing the coagulant dosage,pH and initial turbidity.When MgCl2 dosage was 25.20 mg/L and pH was 11.5,the floc formation time was 12 s and 8 s respectively for 5.... |
