| 摘 要： | 通过单因素及多因素正交实验研究铁屑与粉煤灰处理含高浓度铁锰氨氮废水的有效性。结果表明,铁屑+粉煤灰去除铁锰及氨氮效率均高于单独作用,铁屑+粉煤灰最佳除锰条件为:铁屑与粉煤灰配比3:3,振荡频率150次/min,投加量6 g/100mL,反应时间60 min,pH值6。此条件下铁、锰、氨氮去除率分别为99.8%、86%和11.2%。

| Abstract: | Wastewater that contain higher iron,manganese and ammonia nitrogen is researched using scrap iron and fly ash by the single factor experiment and orthogonal experiment of multiple factors.Single factor experiment shows that the removal efficiency of scrap iron and fly ash is better than independent action for iron,manganese and ammonia nitrogen.The optimum condition of scrap iron and fly ash removing manganese is:ratio of scrap iron and fly ash 3:3,oscillation frequency 150 times per minutes for 60 min,dosing quantity 6 g/100mL,pH value 6.The removal rate of Fe2+,Mn2+,NH3-N are 99.8%,86% and 11.2% respectively under the optimum condition. |
