摘　　要：针对污水处理过程中广泛应用的三氯化铁絮凝剂,作者从机理与研究趋势两方面进行了相关探讨,在机理上阐述了4种机理的特点,包括电中和、吸附架桥、网捕卷扫以及压缩双电层,在研究趋势上提出了对絮体结构、构象、zeta电位以及三氯化铁协同效应的加强研究。Ferric chloride is widely used in the wastewater treatment. The mechanism study on the flocculating of ferric chloride and the recent progress were discussed in this paper. Four typical mechanisms were illustrated including charge neutralization,adsorption bridging,sweep flocculation and compressing thickness of electric double layer. The current research progress was reviewed and intensive study was suggested on floc structure,conformation,zeta potential and the synergistic effect of ferric chloride.
