聚铝和聚铁在造纸废水处理中的交互作用

Study of coagulant interaction in treatment of pulping waste water by using PAC and PFS together

研究采用聚铝和聚铁作絮凝剂 ,并加入有机助凝剂 ,联合作用处理麦草爆破制浆废水的混凝效果 .结果表明 :聚铝和聚铁联合投加的混凝效果优于它们单独投加 ,具有明显的交互作用 .并进一步探讨了絮凝剂投加比例、pH值、水温、投加顺序等因素对交互作用的影响 。

The waste water from pulping of wheat straw was treated by using poly aluminum chloride (PAC), polymerized ferrous sulfate (PFS) and organic coagulant aids together. The results showed that there was an apparent interaction by using PAC and PFS. Some effects on interaction were studied. Focusing on the influence of the amount of Poly (aluminum chloride) and polymerized ferrous sulfate, pH value, temperature and the sequence of two on flocculating result, the optimum operating parameters were acquired.
