摘要:
为掌握原水硬度对除藻效果的影响，以绿藻为研究对象，在原水钙硬度为50~300 mg/L的环境下进行了臭氧和高锰酸钾的混凝除藻实验。混凝实验结果显示，不同的钙离子浓度均能显著提高臭氧和高锰酸钾的混凝除藻效果。当钙离子浓度较低时，臭氧预氧化—混凝除藻效果优于高锰酸钾预氧化—混凝；但当钙硬度＞90 mg/L时，高锰酸钾预氧化—混凝除藻效果则优于臭氧预氧化—混凝。水厂原水的3组平行实验数据也证明在高硬度环境下高锰酸钾预氧化—混凝除藻效果优于臭氧预氧化—混凝。
Abstract:
In order to understand the effect of raw water hardness on algae removal, green algae in raw water with different calcium hardness of 50-300 mg/L was removed by ozone preoxidation-coagulation or potassium permanganate preoxidation-coagulation. Coagulation tests showed that different concentrations of calcium ions could significantly enhance the algae removal efficiency by ozone preoxidation-coagulation and potassium permanganate preoxidation-coagulation. When the concentration of calcium ion was low, the algae removal efficiency of ozone preoxidation-coagulation was better than that of potassium permanganate preoxidation-coagulation. However, when the hardness of calcium was higher than 90 mg/L, the algae removal efficiency of potassium permanganate preoxidation-coagulation was better than that of ozone preoxidation-coagulation. Three sets of parallel test data of actual raw water in waterworks also proved that potassium permanganate preoxidation-coagulation had better algae removal efficiency than that of ozone preoxidation-coagulation in high hardness environment.
