摘　　要：以改性硅藻土为吸附剂处理工业含F废水。研究了改性硅藻土用量、pH值、吸附时间等因素对含F废水中F的去除效率的影响。结果表明:改性硅藻土加入量为100～150mg/L,处理时间为60min,pH值为6～9,室温条件下,用氢氧化钠改性并高温活化后的硅藻土对废水中F离子的去除效果明显优于原土,对含F废水样的处理,除F率可达到97%以上,处理后的废水中F离子浓度达到国家污水排放标准。The treatement methods of industrial fluoride-containing wastewater by modified diatomite were studied. The influence factors on treatment of fluoride-containing wastewater were discussed. The result demonstrated that the treatment efficiency of Diatomite modified is better evidently than the un-modified. The best condition of treatment is ; room temperature, content of modified Diatomite in water 100-150 mg/L, pH 6.0-9.0,treatment time 60 minutes. When treated, the removal of fluoride reached 97% for the industrial sample. The fluorine content in wastewater after treated is under the national water emission standard.
