摘　　要：以家庭洗漱废水为研究对象,采用电化学法处理进行试验研究。考察在不同的槽电压、水力停留时间(HRT)下电化学反应器对废水中CODCr、氨氮、硝酸盐氮、亚硝酸盐氮的去除效果以及对溶解氧(DO)的增加率的影响。结果表明,电化学氧化对氨氮、硝酸盐氮、CODCr的去除有明显效果;对亚硝酸盐氮没有去除效果,反而使其浓度增加;对溶解氧(DO)的增加有显著效果。综合考虑各项水质指标,考虑能耗和经济效益,选择电压20V、停留时间5min处理效果较佳。Electro-oxidation method was adopted to deal with wastewater of family wash water at different bath voltage and hydraulic retention time in order to observe their effect on the removal of CODCr,NH3-N,NO-3-N,NO-2-N and DO.The result showed that electro-oxidation method had obvious effect on the removal of CODCr,NH3-N,and NO-3-N.However,it had no efficiency on the removal of NO-2-N,and would increase the concentration of NO-2-N.Electro-oxidation method had notable effect of increasing the concentration of DO.Finally,considering all the indexes,when the bath voltage was 20V and hydraulic retention time was 5min,and the effect was better.
