摘要
采用自制的聚合硫酸铁(PFS)对一种含氟量较高的水样进行了实验条件下的混凝处理,讨论了在搅拌速度和初始pH不变的情况下,PFS用量及絮凝时间对除氟效果的影响,找出了最适宜处理条件。结果表明:该含氟废水用PFS处理可以收到良好的除氟效果;室温下混凝处理的最适宜条件是:pH=7.0,絮凝时间为30～40 min,PFS用量为1.75 mL·L-1。
The coagulating treatment for a sort of high strenth fluoric wastewater was experimentally conducted with self-prepared polymeric ferric sulphate （PFS）. The effect of PFS dose and coagulating reaction period on removal efficiency of fluorine was discussed on condition that the pH, the stirring rate were both constant. Also, the coagulating conditions were optimized. It was shown that coagulating that fluoric wastewater with PFS brought about a good result, and that the optimized conditions coagulating that sewage at room temperature were as follows： pH=7.0, coagulating reaction period was 30-40 min, and PFS dose was 1.75 mL·L^-1.
