摘要
以KMnO 4为氧化剂,Al 2(SO 4)3·18H 2O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4.16 mg/L,混凝剂投加量263.68 mg/L,pH值为7.54的最佳工艺参数下,铁锰去除率分别可达98.22%和97.49%。
The effects of pre-oxidation and enhanced coagulation technologies were investigated by using KMnO 4 as oxidant,Al 2(SO 4)3·18H 2O 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.
