| 摘 要： | 用自制的无机高分子聚合硅酸铁(PFSS),对砷化镓生产中的含砷废水进行了混凝处理。实验考察了n(Fe)/n(Si)、熟化时间、使用量、出水pH值等对PFSS混凝效果的影响,并与通常所用的几种混凝剂进行了比较。结果表明:在n(Fe)/n(Si)为1∶(0.5～1)、熟化时间为5～7d、使用量为8～12mg/L、出水pH值为6～8时,效果较好,且除砷效果优于常规混凝剂。

| Abstract: | In this paper, polyferric silicate sulfate (PFSS) was prepared and arsenic-containing wastewater from gallium arsenide plant was flocculated by it. The influence of the Fe/Si molar ratio, the aging time, the dosage and the pH of outlet water on coagulation property were experimented and compared with other coagulants. The results show that Fe/Si molar ratio 1∶(0.5～1), the aging time 5～7 d, the dosage 8～12 mg/L and the pH=6～8 of outlet water are preferable conditions, and under these conditions, PFSS has better performance than other coagulants. |
