Optimization of Preparation of Poly-aluminum Ferric Sulfate from Waste Incineration Fly Ash by Response Surface Methodology
摘要
Abstract
The polymeric aluminum sulfate iron flocculant(PAFS)was prepared by acid leaching using waste incineration fly ash from a waste incineration plant in Kunming and used for flocculation treatment of kaolin simulated wastewater.The single-factor experiments of material preparation conditions were discussed,and the optimal material preparation conditions were obtained by optimizing the experimental conditions through response surface analysis technique.The results showed that when the polymerization time was 64.05 min,the polymerization stirring speed was96.89 r/min,and the polymerization temperature was39.76℃,the predicted value of turbidity removal rate of the flocculant for the simulated wastewater was 35.9%and the actual value was 35.95%,which were less different,indicating that the response surface model was reliable and the optimal parameters were credible.关键词
