摘　　要：采用双铝极板,利用电絮凝法对城市生活污水二级处理出水进行处理,以氨氮、总磷和COD的去除率等为指标,通过探索电解时间、极板间距、电流密度、pH值等参数的单因素影响分析,研究各参数对处理效果的影响,确定最佳条件。实验表明,采用双铝极板电絮凝法深度处理城市生活污水二级处理出水可有效的去除氨氮、总磷和COD。Using dual aluminum plate electrocoagulation and the effect of treatment was studied by respectively changing the electrolysis time, plate distance, current density, pH value of raw water and other parameter. According to the indicators of the removal rate of NH3 - N, TP and COD in the outlet of secondary treatment in urban wastewater treatment, orthogonal test method was used to obtain the best operating conditions of treatment. It showed that electrocoagulation can effectively treatment the outlet of secondary treatment in urban wastewater treatment.
