| 中文摘要: |
| 以KMnO4为氧化剂，Al2(SO4)3·18H2O为混凝剂，含铁锰离子地下水为模拟用水，考察预氧化强化混凝法的效果。利用响应面设计试验，分析氧化剂投加量、混凝剂投加量和pH值对铁锰去除的交互作用。模型优化结果显示，在氧化剂投加量416 mg/L，混凝剂投加量26368 mg/L，pH值为754的最佳工艺参数下，铁锰去除率分别可达9822%和9749%。 |
| 英文摘要: |
| The effects of pre oxidation and enhanced coagulation technologies were investigated by using KMnO4 as oxidant， Al2(SO4)3·18H2O as coagulant， and iron manganese groundwater as simulated samples. By response surface design experiments， the interactions of oxidant dosage， coagulant dosage and pH on the removal of iron and manganese were analyzed. Results from the optimized model showed that the removal rates of iron and manganese were 98.22% and 97.49% respectively， with the optimal technological parameters of oxidant 4.16 mg/L， coagulant 263.68 mg/L and pH 7.54. |
