脉冲三维电催化法深度处理餐厨废水的研究

Study on Advanced Treatment of Food Wastewater by Three-Dimensional Electrocatalysis of Pulsed Power Supply

为了采用脉冲三维电催化法深度处理餐厨废水,通过试验研究其最佳供电参数,根据充放电方程计算理论最佳占空比及频率,并与试验结果进行对比分析。研究结果表明,最佳电源参数为:占空比50%、频率200 Hz,反应时间30 min,出水水质可达《污水综合排放标准》(GB 8978—1996)一级标准,达标能耗为4.0 kWh·t^(-1)(0.022 kWh·g^(-1) COD)。

The advanced treatment of food wastewater was conducted by three-dimensional electrocatalysis of pulsed power supply.The optimal power supply parameters were investigated and contrasted with the theoretical values calculated from the charge-discharge equation.The results show that the optimal power supply parameters include the duty cycle of 50%and frequency of 200 Hz.Under these conditions,the effluent quality can achieve theⅠ-class criteria in Integrated Wastewater Discharge Standard(GB 8978—1996)after the electrocatalysis for 30 min,and the corresponding energy consumption is 4.0 kWh·t^(-1)(0.022 kWh·g^(-1) COD).
