摘要
以还原性铁粉和高锰酸钾制备了新生态铁盐(FIS)用于去除水中的磷酸根,研究了pH、高锰酸钾投加量、还原性铁粉投加量等对除磷效果的影响。试验结果表明:FIS除磷效果随还原性铁粉、高锰酸钾投加量的增加而升高,随溶液初始磷含量增大而降低;FIS除磷时最佳pH为3,浊度变化对除磷效果无明显影响;当高锰酸钾投加量为3 mg/L、还原性铁粉投加量为1 g/L时,FIS对模拟含磷水和实际生活污水中磷的去除率分别为98.16%、84.17%。
Freshly formed iron salts （FIS） have been prepared by Fe and KMnO4 to remove phosphorus from water. The effects of pH,dosage of KMnO4,dosage of reductive Fe powder,etc, on the dephosphorization efficiency are studied. The results show that the phosphorus removing efficiency of FIS increases with the increase of dosages of Fe and KMnO4 and decreases with the increase of initial phosphate concentration. The optimal pH is 3 for the dephos- phorization with FIS. The changes of turbidity do not have obvious effect on the dephosphorization efficiency. When the dosage of KMnO4 and reductive Fe are 3 mg/L and 1 g/L, the phosphorus removing rates from simulated phospho- rus-containing water and domestic sewage by using FIS are 98.16% and 84.17%, respectively.
