硫酸亚铁去除老澴河水中磷的研究

Study on Removal of Phosphorus from Huanhe River with FeSO 4

为了探究化学法除磷的效果,用硫酸亚铁处理孝感市孝南区老澴河水体中的总磷,在静态条件下探讨了铁磷摩尔比、pH、搅拌速率、搅拌时间和凝聚时间对磷的去除效果。结果表明:在温度为20℃、总磷浓度为0.0953 mg/L、铁磷摩尔比为1.0、pH为8.0、转速为200 r/min、搅拌时间为9 min、絮凝时间为40 min的条件下能够获得良好的去除效果,去除率可达80.30%。

In order to explore the effect of chemical removal of phosphorus,ferrous sulfate was used to treat the total phosphorus in the water of Huanhe River in Xiaonan District of Xiaogan City.Under the static conditions,the effect of the molars of iron and phosphorus,pH,stirring rate,stirring time and condensation on the removal of phosphorus were discussed.The results showed that when the temperature was 20℃,the total phosphorus concentration was 0.0953 mg/L,the iron-phosphorus molar ratio was 1.0,the pH was 8.0,the rotation speed was 200 r/min,the stirring time was 9 min,and the flocculation time was 40 min,the removal effect can be good and the removal proved to be 80.30%.
