| 摘 要： | 以含磷水样为研究对象,考察了不同混凝剂(聚合氯化铝、三氯化铁及三氯化铝)的除磷效果及其影响因素,同时比较了不同碱化度PAC除磷效果的差异,明确了聚合氯化铝、三氯化铁及三氯化铝的最佳投加量和最佳pH值.搅拌条件对除磷效果的影响结果表明,混合强度的增大对除磷效果有一定的提高,混合时间以60 s为宜. |
| 关 键 词： | 混凝 除磷 碱化度 最佳投加量 |

| Abstract: | The characteristics of phosphorus removal using three various coagulants,polyaluminum chloride(PACl),ferric chloride and aluminum chloride,were compared.The influence of coagulant dosage and other effective factors were discussed.Meanwhile,PACls with different basicity were investigated.The optimum dosage and pH were discussed for each coagulant.The mixing intensity and time were also studied.The characteristics of phosphorus removal were improved with the enhancement of the mixing intensity.The optimum mix... |
| Keywords: | coagulation phosphorus removal basicity optimum dosage |
