摘　　要：利用纳米催化电解法处理磺胺甲噁唑废水,研究pH、盐度、电解电压、电解时间等因素对处理磺胺甲噁唑的影响。结果表明,对于浓度为80 mg/L的磺胺甲噁唑废水,最佳的电解条件是pH=13,盐度为15‰,电解电压为6 V。在此条件下,CODMn的去除率达到76%,磺胺甲噁唑的去除率为83%,说明纳米催化处理对此类难以生物降解的抗生素具有很好的去除效果,为该类废水的处理提供了一种可行的方法。The sulfamethoxazole wastewater was treated by nano-catalytic electrolysis. The effects of pH, salinity, electrolysis voltage and time on the treatment of sulfamethoxazole were studied. The results showed that for the concentration of 80 mg/L sulfamethoxazole wastewater, the optimum electrolysis conditions were as follows: pH=13, salinity was 15‰, and electrolysis voltage was 6 V. Under these conditions, the removal rate of CODMn reached 76%, and the removal rate of sulfamethoxazole was 83%. It showed that nano-catalytic treatment technology had a good effect on the removal of such poorly biodegradable antibiotic, and provided a feasible method for the treatment of this kind of wastewater.
