摘　　要：以碳布为阴阳极材料构建一种新型的生物电化学系统(BES),研究该系统在不曝气条件下对城市污水的处理效果,并与传统的厌氧和好氧处理方法进行比较。结果表明,该BES处理城市污水是可行的,与传统曝气法相比能够显著降低能耗。在进水COD cr为350 mg/L、NH3-N为15 mg/L、水力停留时间(HRT)为24 h时,电化学强化生物处理系统对COD cr和NH3-N的去除率达84%和80%,优于同等条件下的厌氧、好氧生物处理方法。BES的输出电压最高为211 mV。This study adopted a novel bio -electrochemical system（BES）. The cathode and anode were both low- cost car- bon cloths. The bio - electrochemical systems were investigated to treat municipal wastewater with no energy input, and were com- pared with traditional anaerobic and aerobic treatment methods. The results showed that adopting BES to treat municipal wastewater was feasible, saving energies obviously. Under the hydraulic retention time （HRT） of 24h, initial CODer 350 mg/L and NH3 - N of 15 mg/L, the removal rates of CODor and NH3 - N were 84% and 80% in the BES, which is higher than the results of traditional anaerobic and aerobic treatment methods. The system produced up to 211 mV of electrical potential across a 500 - ohm resistor connecting cathode and anode.
