摘要
介绍了氧化铁涂层砂和未涂层石英砂除氟过滤比较：氧化铁涂层砂除氟效果显著，去除率达９０ ％ 以上，基本遵循低ｐＨ 高去除率的规律；石英砂对水中的氟无任何去除效果。
A comparison was made between the iron oxide coated sand (IOCS) and quartz sand in filtration for fluoride removal. The effect of IOCS on fluoride removal was noticeable with removal efficiency of more than 90%, and the removal efficiency increased with the decrease of pH value. However, no fluoride removal effect was observed by using quartz sand.
