摘要
采用电化学氧化法方法,以Ti/IrO2-Pt板为阳极,铜板为阴极,处理模拟生活污水,研究了Cl-浓度、极板间距以及电流密度等因素对模拟生活污水中氨氮(NH4+-N)去除效果的影响,并分析了污水处理能耗。实验结果表明:当进水NH4+-N浓度约为5 0 mg/L,控制极板间距为2 cm,Cl-浓度为2 00 mg/L,电流密度为12 mA/cm2,电解时间7 0 min,NH4+-N去除率可以达到1 00%,处理1 m3NH4+-N废水需消耗的电能为1.4 kwh。
Simulated domestic wastewater has been treated by electrochemical oxidation technology using Ti/IrO2-Pt anode and Cu cathode.The parameters of Cl-concentration,electrode distance and current density were investigated,and the energy consumption was analyzed.Experimental results indicate that the removal rate of NH4+-N will be up to 100% with 1.4 kwh of electricity for 1ton of domestic sewage when the influent NH4+-N concentration is 50 mg/L,the electrode distance 2 cm,the Cl-concentration 200 mg/L,and the current density 12 mA/cm2.
