摘　　要：针对XY水厂水源地氟含量超标的问题,在调研LM湖氟含量分布以及现有处理工艺除氟效能的基础上,探讨针对该水厂的强化除氟方案。LM湖湖区范围内氟化物含量在0.95~1.40 mg/L之间,而XY水厂水源地的氟含量近年来呈现持续上升趋势,且水厂现有工艺对氟基本无去除效能。结合XY水厂近期要扩建的基本状况,适用于该水厂的除氟方案为新建基于粉状和球状这两种形式的羟基磷灰石组合除氟工艺,可将水中的氟含量降至0.1~0.3 mg/L,并将处理出水与现有工艺出水按1∶2的比例混合,即可使出厂水水质达到《生活饮用水卫生标准》的要求。Aiming at exceeding the standard of fluoride content in the water source, the distribution of fluoride and removal performance of the existing water treatment process in XY water plant were investigated. In addition, the suitable process to enhance the removal of fluoride was discussed. The resuits showed that the content of the fluoride at different site of the LM Lake was between 0.95 - 1.40 mg/ L and the fluoride in water source of the XY water plant was increasing in recent years. The process in the XY water plant showed poor removal for the fluoride. The optimized fluoride removal scheme was the combined process based on the powdered and spherical hydroxyapatite （HAP）. The fluoride concentration of outflow of the process was steadily below the limit of Standards for Drinking Water Quality （ GB 5749 -2006）, even if after the mix with the untreated water at a proportion of 1 ： 2.
