摘要
降低原水中磷的浓度可以控制水的生物稳定性,通过混凝试验,对6种常用混凝剂的除磷效果进行了比较和分析,结果表明聚铁(聚合硫酸铁,PFS)的除磷能力最强,影响聚铁除磷效果的主要因素及排序为加药量→快转速→pH→慢转速,各因素的最佳值分别为加药量5 mg/L,快转速900 r/min,慢转速100 r/min,pH为7,此时,聚铁的磷去除率可达85.3%.
Low level of phosphorus can limit bacteria regrowth to ensure the biological stability of drinking water. So six coagulants were examined in coagulation experiments, and their effect of phosphorus removal was checked. The results indicate that PFS（Poly-Fe） is the most powerful in phosphorus removal. And the best working condition was given after the experiments.
