| 摘 要： | 采用FeSO_4和KMnO_4反应制备新生态铁锰氧化物除磷,比较了Fe_2(SO_4)_3和FeSO_4/KMnO_4两种混凝工艺的除磷效果,并考察了FeSO_4/KMnO_4除磷过程中的影响因素.结果表明,在相同条件下,FeSO_4/KMnO_4的除磷效果比Fe_2(SO_4)_3的要好,当铁盐投量(以Fe计)为5mg/L时,FeSO_4/KMnO_4和Fe_2(SO_4)_3对磷的去除率分别为90.2%和82.3%;KMnO_4与FeSO_4的最佳物质的量比为0.33;FeSO_4/KMnO_4的除磷效果随Fe~(2+)投量的增加而升高,随初始TP浓度和pH的增加而降低;当混凝时间由10 min增至60 min时,FeSO_4/KMnO_4对磷的去除率无明显变化.

| Abstract: | Freshly formed Fe/Mn oxide was prepared by FeSO4 and KMnO4 to remove phosphorus.The phosphorus removal efficiencies of Fe2(SO4)3 and FeSO4/KMnO4 coagulation processes were compared,and the factors affecting phosphorus removal by FeSO4/KMnO4 were investigated.The results show that the phosphorus removal efficiency of FeSO4/KMnO4 is better than that of Fe2(SO4)3 under the same conditions.When the dosage of Fe is 5 mg/L,the phosphorus removal rates of FeSO4/KMnO4 and Fe2(SO4)3 are 90.2% and 82.3% respectively.... |
