不同混凝剂在造纸废水中的性能实验研究

Research of Different Coagulants in Wastewater Treatment

以制浆造纸厂废水为对象，采用烧杯混凝实验，通过改变PH值、药剂投加量等方法，比较了各种絮凝剂的去除效果、投加量和其成本价格，认为使用聚合氯化铝（PAC）作为该废水处理的絮凝剂（投加量约为40mg／L）去除效果最好。最为经济。

By using paper mill wastewater as the study object, this paper compares the various flocculant＇s removal effect, dosing quantity and cost price by using jar coagulant test through changing PH value, coagulant dosing quantity and other methods. It＇s considered that using poly aluminium chloride （PAC） as the water＇s flocculant can gain the best removal effect and the most economical effect.
