摘要
构建电解-微生物燃料电池耦合系统处理偶氮染料废水,考察了该系统的运行性能。运行结果表明:电解池的最优运行电压为2.0 V,在此条件下,其对废水中重氮基团的破解和色度的去除效果最佳。该耦合系统对废水色度和COD的去除率分别可达到91.0%和86%,且能够输出电压(0.66±0.03)mV,产电性能良好。
Azo dyes wastewater was treated by constructed combing electrolysis and microbial fuel cell,and its ope-rating performance was investigated.The operating results showed the optimum applied voltage of the electrolysis cell was 2.0 V,at which electrolysis cell achieved the highest decolorization rate and destroying effect of azo bond(—N=N—)existed in the wastewater.The decolorization rate and COD removal rate presented by the combination of electrolysis and microbial electrolysis cell were up to 91.0%and 86%,respectively,with the output voltage of(0.66±0.03)mV,indicating excellent electricity generation.
