摘　　要：含氟工业废水危害大 ,处理困难 ,采用新型无机高分子混凝剂能有效降低废水中的氟。本文在实验条件下制备了不同金属离子的聚硅酸氯化物 ,考察了pH值 ,混凝剂用量 ,碱化度B和Fe(Al) /A物质的量比对除氟率的影响 ,并利用红外光谱和透射电镜对混凝机理进行探讨。The industrial wastewater containing fluoride which was difficult to be removed was harmful to the environment.The wastewater could be treated by using new inorganic high molecular coagulant.The polysilicate chloride with metals was prepared in the experiment.The pH value,dosage of coagulants,basicity and molar ratio of Fe(Al)/Si on removal efficiency of fluoride were discussed. The removal mechanisms of polysilicate-metals salts were also discussed by using infrared spectrum and transmission electron microscope.
