| 摘 要： | 对改性钢渣在机械搅拌条件下的除藻效果进行了研究,并分析了改性钢渣预处理与混凝联用工艺对藻类的去除效果和协同作用.实验表明,钢渣经改性后,既能有效地去除水中的藻类,又能降低藻的光合活性,抑制藻的生长;高温活化改性钢渣预处理与混凝联用工艺对藻类有很好的去除效果,其对叶绿素a的平均去除率达91.4％,远高于单纯的钢渣预处理和混凝工艺.这暗示了两者之间在除藻方面存在协同作用.

| Abstract: | The effects of the modified steel slag on the algae removal under conditions of mechanical stirring were studied, and the algae removal and synergies of the pretreatment of modified steel slag and its association with coagulation were analyzed. The results indicated that the modified steel slag could effectively remove the algae in the water, reduce the photosynthetic activity of algae and inhibit the growth of algae. The high temperature acti- vation modified steel slag pretreatment associated with coagulation processes had a good effect on algae removal and the average removal rate of chlorophyll a was over 91.4%, much higher than that of the slag pretreatment and coagulation process. The results suggested that the two processes have synergistic effect on removing algae. |
