| 摘 要： | 目的]选择适宜的高氟饮用水处理方法。方法]针对相同的高氟饮用水水质，利用活性Al2O3吸附法与CaO＋KH2PO4沉淀法进行对比研究，并对2种除氟方法的除氟效果、处理成本、处理周期和出水量等方面作了对比。结果]将氟化物浓度为1．75mg／L的高氟水降至1．0mg／L以下，吨水活性Al2O3和CaO＋KH2PO4的投加量分别为20．0kg和2．05kg。确定了CaO／KH2PO4的最佳投药量为0．400／0．625，在该配比下得到的水质结果为：氟质量浓度为0．86mg／L，pH值为7．02，总硬度144mg／L，硫酸盐质量浓度68．5mg／L，氯化物质量浓度为46．2mg／L，达到了饮用水水质标准。活性Al2O3吸附法较CaO＋KH2PO4沉淀法的处理周期短，设备和工程投资少，而CaO＋KH2PO4沉淀法在处理效果、出水量以及能耗方面占优势。结论]活性Al2O3吸附法适用于原水氟化物超标倍数低，且总硬度偏低的高氟水水质；CaO＋KH2PO4沉淀法适用于原水K^＋和PO4^3-偏低的水质。

| Abstract: | Objective] The suitable method for the treatment of drinking water was optimal.Method] Two methods for the treatment of drinking water with high fluoride: the active Al2O3 assay and CaO+KH2PO4 precipitation,were compared in their efficiency,cost,treating duration,water amount and so on.Results] The result indicated the added quantity of active Al2O3 and CaO+KH2PO4 was 20 kilograms and 2.05 kilograms,respectively,if the concentration of the fluoride of 1.75 mg/L in per ton's water was reduced to below 1.0... |
