| 摘要:以化学热磨机械浆（CTMP）制浆废水为底物,采用铁氰化钾阴极微生物燃料电池（MFC），对MFC处理CTMP制浆废水的可行性和废水CODCr浓度对MFC产电性能的影响进行研究。结果表明，MFC最大功率密度随废水CODCr浓度的增大而升高，最高为233 mW/m2，CODCr去除率达到54.3%～62.4%；当CODCr增大至5200 mg/L以上时，过高的CODCr浓度抑制微生物活性，电池最大功率密度和CODCr去除率分别降低至34.2 mW/m2和32.8%。CTMP制浆废水可以作为MFC底物，在产电的同时实现有效降解，这为废水资源化利用提供了新途径。 |
| Abstract:The possibility of electricity generation in the ferricyanide-cathode microbial fuel cell (MFC) with CTMP wastewater as substrate and the effect of CODCr concentration on MFC performance were investigated. The results showed that the electricity generation increased with increasing CODCr concentration, the maximal power density of 233 mW/m2 was obtained and CODCr removal efficiency reached 62.4%. When the CODCr concentration increased to over 5200 mg/L, the microbial activity was inhibited by high CODCr concentration, the maximal power density and CODCr removal efficiency decreased to 34.2 mW/m2 and 32.8% respectively. CTMP wastewater can be used as substrate in MFC for electricity generation while it is degraded, which offers a novel method for the treatment and recycle of papermaking wastewater. |
