新型复合絮凝剂的除磷性能研究

A Study on the Phosphorus Removal Performance of A New Compound Flocculant

研制了新型复合絮凝剂NF,并研究了pH值、初始磷浓度、有机物HA和浊度存在对其除磷效果的影响。结果表明,新型絮凝剂NF对总磷的去除率高达98%以上,而且在弱酸性到中性的pH值范围内除磷效果都比较好;受不同初始总磷浓度影响也比较小;有机物HA的存在对NF的除磷效果有一定的影响,浊度的存在有助于NF对总磷的去除。

A new compound flocculant NF was developed,and the effects of pH,initial phosphorus concentration,organic HA and turbidity on phosphorus removal were studied.The results showed that the removal rate of the new flocculant NF was up to 98%,and the phosphorus removal efficiency was better in the range of weak acid to neutral pH,and the influence of different initial total phosphorus concentration was relatively small.The presence of organic HA had a certain effect on the phosphorus removal effect of NF,and the presence of turbidity contributed to NF removal of total phosphorus.
