| 摘 要： | 在已有的聚合硫酸铁性能的基础上,针对其水解速度快、不稳定的特性,通过加磷实验,改变其原有的不稳定性能,从而提高聚合硫酸铁的稳定性及处理废水的效果。实验结果显示,当磷铁比(摩尔比)达到0.12时,聚合硫酸铁的稳定性较好,pH值和电导率随着时间的变化幅度较小,同时用处理长江水为例测定了改性后的聚合硫酸铁具有更稳定的特性,而且对浊度和色度的去除效果较好。

| Abstract: | Based on the performance of polymeric ferric sulfate,aiming at its high hydrolysis speed and unstability,though increasing the content of phosphorus in this experiment,in order to change its unstability,mean while enhancing the stability of the PFS and processing efficiency of wastewater treatment.Experimental results showed that the stability of the PFS was good when the P/Fe reached 0.12,and the curves of pH value and conductivity changed a little with time changing.With handling of the Yangtze River water,PFS with phosphorus was more stable then before and had an good effect on the treatment of turbidity and chroma. |
