| 摘 要： | 采用CaO+KH2PO4工艺对焦作市高氟区地下水进行降氟处理。通过实验研究,分析了该工艺的除氟机理和最佳设计参数。实验结果表明,CaO+KH2PO4工艺应用于当地高氟水的水质处理中,CaO/KH2PO4=0.4/0.625为最佳的药量配比,即针对氟质量浓度为1.75 mg/L的地下水,每吨水最佳投药量为:CaO/KH2PO4=0.8 kg/1.25 kg。

| Abstract: | The CaO KH2PO4 technique was applied to the removal of fluorine in the groundwater of high fluorine in Jiaozuo city.The mechanism and the optimal operation parameters were studied by experiments.Results indicate that the best ratio of CaO/KH2PO4 is 0.4/0.625 for the treatment of the high fluorine groundwater.When the concentration of fluoride in groundwater is 1.75 mg/L,the best amounts of CaO and KH2PO4 are 0.8 kg/t and 1.25 kg/t respectively. |
