摘　　要：通过混凝除磷实验,考察了新型混凝剂聚硅铁的除磷作用并探讨了聚硅铁投加量、Fe/P摩尔比,水样的pH值和初始磷浓度等参数的变化规律。实验结果表明,PSF的除磷效果不仅与PSF的投药量及Fe/P有关,而且与水样的pH值和初始磷浓度密切相关,在投量为0.2mmol·L^-1,pH值为8.0~10.0及Fe/P=2.5的条件下,除磷效果最佳。A new coagulant-polysilicate ferric （PSF）was prepared to study phosphorus removal by coagulation with PSF. The variation of phosphorus removal efficiency with the change of operation parameters such as coagulant dosage,Fe/P mol ration,initial phosphorus concentration and pH were discussed. The result showed that the removal efficiency is very sensitive to the dosage of PSF,Fe/P mol ration,pH and initial phosphorus concentration,achieving best performance at the dosage of 0.2mmol·L-1,pH=8.0~10.0 and Fe/P mol ration=2.5.
