| 摘 要： | 采用溶胶-凝胶法制备Fe3O4-PAC磁性絮凝剂,通过投加量和pH值的改变对其絮凝性能进行研究。研究表明,制备磁性絮凝剂的最佳条件是:将4.60 g PAC溶于20 mL的蒸馏水,调节pH=8,超声分散10 min后,加入0.19 g磁性Fe3O4;处理污水时磁絮凝剂的最佳投放量为0.02 g/L,最佳pH=8。

| Abstract: | Magnetic Fe3O4-PAC floeeulant was prepared by solgel method,studied its floeeulation performanee,by varying the dosing quantity and pH. The researeh shows that the optimal eonditions for prep-aration of magnetie floeeulants is 4. 60 g PAC dissolved in 20 mL of distilled water,adjust pH value is 8, after ultrasonie dispersion 10 min,add 0. 19 g magnetie Fe3O4 ,and the optimal eonditions for sewage purifieation is 0. 02 g/L of quantity of magnetic flocculant,the pH value is 8. |
