摘要:: 城市排水管网存在管道泄露、爆裂等问题，需实时监控其液位、气体浓度等参数。针对目前下水道缺乏监测装置和驱动装置的电池更换不便等问题，提出利用微生物燃料电池(MFC)处理下水道污水获得电能，为监测、照明等设备供电，同时降解清洁污水中的部分有机污染物。为保证空气阴极稳定的气固液三相反应界面和避免高速水流对MFC性能的损害，研制水滴状浮标式MFC反应器结构。结果表明：MFC处理实际污水获得的能量经能量采集电路收集和低功耗能量管理能驱动监测设备。

Abstract:: Accidents like leakage or pipeline bursting frequently happened in urban drainage network. Real time monitoring of gas concentration and other relevant parameters is in urgent need. Aiming to overcome the lack of monitor devices, the inconvenience of changing batteries and the high expense of waste water treatment, in this study, microbial fuel cell(MFC) was applied to dispose sewage water and provide electric power for monitor and lighting equipment simultaneously. The original drop-like and buoy-type structure of MFC reactor ensureed that the cathode remains in gas-liquid interface, while avoiding potential destruction from high-speed flow. Energy harvesting module collected the tiny amounts of energy and monitored parameters periodically through low-power-consumption energy managing module.
