Simultaneous Removal of Nitrogen and Phosphorus by Electrocoagulation Process

  • 摘要: 采用电絮凝法去除废水中的氨氮和磷,电极板采用铝板或不锈钢板,研究了电絮凝除磷热力学与动力学过程,考察了不同工艺参数对氨氮和磷去除效果的影响. 结果表明:相对于铝电极而言,不锈钢电极更适宜于电絮凝去除氨氮和磷;Redlich-Peterson方程能较好地描述电絮凝产生的絮凝体对磷的吸附行为,得到的Gibbs自由能变都在-20~0kJ/mol范围内,并且吸附是自发进行的吸热过程,升高温度有利于吸附;由于假二级动力学方程拟合时其相关系数(R2)均大于0.98,故假二级动力学方程更适宜描述电絮凝产生的絮凝体对磷的吸附动力学过程;随着电流密度的增加,氨氮和磷的去除率呈逐渐上升趋势;在强碱性条件下,氨氮的去除率相对降低,酸性条件下水中磷的去除率较高,随着溶液pH的增高,磷的去除率呈逐渐降低趋势. 去除氨氮和磷的能耗分别为0.15~0.50和0.02~0.04kW·h/g.
