| 摘 要： | 粉煤灰复合吸附剂是一种新型得除氟剂，具有良好的吸附性能，在一定条件下，可用于处理高含氟量的工业废水，粉煤灰复合吸附剂处理50mg/L左右的含F^－废水时，当投加量为0．6％－0．8％时，去除率可达90％以上，从而达到排放标准，粉煤灰复合吸附剂所需原料易得，除氟后可将原料固化制成建筑用砖，合理利用。

| Abstract: | Fly ash compounded mixture is preactivated at proper temper ature before it is used to treat wastenater containing fluorine about 50mg/L.Fluorine removal reaches 90% when the addition is 0.6%-0.8% at a pH value range from 3 to 11.The flourin content in purified water is about 8mg/L. |
