摘要:

构建了双室微生物燃料电池-厌氧膜生物反应器(DcMFC-AnMBR)耦合工艺系统,探究了耦合系统处理含磺胺嘧啶(SDZ)养猪废水的产电、污染物去除及产气性能,同时分析了SDZ影响下膜污染特征变化。结果表明:1.0 mg/L SDZ存在下DcMFC-AnMBR耦合系统平均输出电压和库仑效率分别下降了6.11%和7%,耦合系统最大功率密度为35.34 mW/m2,COD去除率始终保持在98%,平均生物气产量为542.59 mL/d。同时,SDZ的存在使污泥混合液Zeta电位绝对值升高了25.83%,污泥平均粒径减小了14~16 µm,可溶性微生物产物(SMP)和胞外聚合物(EPS)平均浓度分别上升了7.76%和35.43%。耦合工艺系统运行期间跨膜压差(TMP)始终在0附近,其污染缓解原因可能是电活性微生物对SMP和EPS进行了有效的氧化降解。

Abstract:

A dual-chamber microbial fuel cell-anaerobic membrane bioreactor(DcMFC-AnMBR) coupled process system was constructed. The power production, pollutant removal, and gas generation performance of the coupled system for treating swine wastewater containing sulfadiazine(SDZ) was investigated, and the change of membrane pollution characteristics under the influence of SDZ was also analyzed. The results showed that in the presence of 1.0 mg/L SDZ, the average output voltage and coulombic efficiency of the DcMFC-AnMBR coupled system decreased by 6.11% and 7%, respectively. The maximum power density of the coupled system was 35.34 mW/m2, the COD removal rate remained at 98%, and the average biogas production was 542.59 mL/d. Meanwhile, the presence of SDZ increased the absolute value of Zeta potential of sludge mixture by 25.83%, the average particle size of sludge decreased by 14-16 µm, and the average concentrations of soluble microbial products(SMP) and extracellular polymers(EPS) increased by 7.76% and 35.43%, respectively. The transmembrane pressure(TMP) was consistently near zero during the operation of the coupled process system. The cause of membrane fouling mitigation in coupled systems could be attributed to the oxidative degradation of SMP and EPS by electroactive microorganisms.
