摘　　要：结合前期研究所确定的地表水除氟方案,建设了500m^3/d的生产性试验装置,并通过连续的生产性试验对工艺参数进行了优化,得到该除氟装置的最佳运行参数如下:混合除氟材料的投加量为100mg/L、絮体回流比为15%、反应时间为20min左右。在最佳运行条件下,除氟装置最终出水氟含量稳定在0.1mg/L左右、浊度在0.3NTU左右、铝含量在0.1mg/L左右,其他主要水质参数也均能满足我国《生活饮用水卫生标准》(GB5749—2006)的相关要求。In combination with the fluoride removal schemes for surface water determined in the previous study, a 500 m^3/d production test device was constructed, and continuous production tests were carried out to optimize the process operation parameters and to detennine the efficiency of the novel fluoride removal process. The results showed that the optimal operation parameters of the process were as follows: the dosage of mixed fluoride removal material was 100 mg/L, the floc reflux ratio was 15%, and the reaction time was about 20 min. Under the optimal conditions, the fluoride content in the effluent was maintained at about 0. 1 mg/L, the turbidity was about 0. 3 NTU, the aluminum content was about 0. 1 mg/L, and other major water quality parameters could meet the requirements in Standards for Drinking Water Quality ( GB 5749 - 2006).
