污水处理中聚合氯化铝和聚丙烯酰胺配合使用需要注意哪些?

2018/6/25 15:44:10 浏览:835次

聚合氯化铝和聚丙烯酰胺在污水处理上应用的领域广泛,占有非常重要的地位。聚合氯化铝和聚丙烯酰胺在使用过程中,常常配合起来使用。首先来总得分析一下他们的关系,之后向大家介绍一下混合的步骤、注意事项和相关的知识。洗涤剂生产废水具有成份复杂、废水中CODcr和LAS成分含量高且难以直接生物降解、废水的pH值较低等特点 ,同时废水中的洗涤剂成份达到一定浓度时会影响废水处理的曝气、沉淀、污泥消化等过程 ,在实际废水处理过程中常采用絮凝剂解决高浓度LAS难于生物降解的问题,因此在絮凝处理中研究絮凝剂种类的选择、用量及其影响因素等具有重要的现实意义。

絮凝剂聚合氯化铝江苏快3用量 絮凝剂的用量是否合理关系到沉淀是否彻底、处理是否更有效及生产成本是否更低,因此需要对此进行实验以准确确定其用量。实验所用废水的CODc 为4480 mg/L,根据实验方法,在实验过程中固定聚丙烯酰胺的加入量为10mg/L,pH值为7.0,仅改变絮凝剂PAC的用量。考察絮凝剂PAC用量对CODcr去除率的影响,实验结果见图1。图1表明,废水的CODc~去除率先随着絮凝剂PAC加入量的增加而上升,当絮凝剂聚合氯化铝的用量在1.5g/L左右时,废水中CODcr去除率最高,达到81%以上;而当絮凝剂加入量超过1.5g/L时,CODcr去除率开始下降。因为絮凝剂聚合氯化铝加入量不足时,絮凝处理不充分,并且絮凝剂聚合氯化铝水解时产生的H 较多,导致废水的pH值降低,改变了絮凝反应条件,抑制了絮凝剂PAC同废水的结合和反应,降低了废水处理效率;而絮凝剂聚合氯化铝用量过大时,废水中微粒被过多的絮凝剂所包围,失去同其它的微粒结合的机会,因而不易凝聚,同时此时水解产生较多的OH-,导致废水的pH值增大,改变了絮凝反应条件,降低了处理效率。
