摘　　要：以羟基磷灰石为降氟剂 ,分别用一次性混凝沉淀法和动态过柱法对羟基磷灰石的现场饮水除氟效果进行评价。结果表明 ,一次性混凝沉淀法除氟容量为 4.19m g/ g,该法虽然操作简便 ,但试剂投加量大 ,制水成本较高 ;动态过柱法穿透除氟容量为 6 mg/ g,该法羟基磷灰石可再生重复使用 ,制水成本低、除氟容量高、操作简便 ,适合在我国高氟水地区使用。In order to evaluate the effect of synthetic hydroxyapatite on drinking water defluoridation, a coagulative precipitation method and a flow column system was tested in the fields The defluoridation capacity of coagulative precipitation method was 4 19 mg/g, and the method was simple on operation, but more reagents were needed with high cost for operation The defluoridation capacity of flow column system was 6mg/g and the saturated hydroxyapatite could be reused after regeneration The operation of household defluoridator based on flow column system is simple, with low cost and high capacity in defloridation The system will be applied in the fluorosis areas.
