【摘要】 针对低温环境下,微生物燃料电池中微生物活性会受到抑制,处理污染物效能低的问题,在反应器中投加甜菜碱来增强微生物活性的方法,进行甜菜碱对低温下MFC处理硝酸盐污染的研究。结果表明:当对培养驯化完成的MFC投加甜菜碱时,MFC对进水中的COD和NO-3的处理效果增强,最佳投加量为0.7 mmol/L,此时与未投加甜菜碱的反应器相比,COD的降解率增加了18.1%,对NO-3的降解率提高了41.2%。更多还原

【Abstract】 For the problems about microbial activity inhibited in microbial fuel cells,low efficiency of treatment of pollutants in low-temperature environment,adding glycinebetaine in the reactor to enhance microbial activity,the paper researched the influences of glycinebetaine on MFC treating nitrate at low temperature. The results showed that: Adding glycinebetaine in MFC in the muiture perial,the MFC treatment effect for influent COD and NO-3enhanced,the best dosage was 0. 7 mmol / L,compared with no dosing glycinebetaine reactor,COD degradation rate increased by 18. 1%,and NO3-degradation rate increased by 41. 2%.更多还原
