Online Microbial Fuel Cell Biofilm BOD Sensor

废水中有机污染的监测是水处理行业面临的一项艰巨挑战。由于采样不频繁，污染很有可能在未被检测到的情况下排放到环境中，并导致下游进一步的问题。生物电化学传感系统是一种新兴的技术，它利用生长在电极上的生物膜将有机污染转化为电能。根据发电量，可以确定有机污染物的量。因此，与现有的需要5天的测量相比，这种方法可以用于提供连续的在线废水监测。该项目将提供一个基于生物电化学系统的原型传感器，能够对现有的污水处理厂基础设施进行改造，以便快速测量生化需氧量(有机污染)和毒性。

Monitoring of organic pollution in wastewater is a difficult challenge for the water treatment industry. Due toinfrequent sampling there is a high possibility that pollution could be discharged into the environmentundetected and lead to further problems downstream.Bioelectrochemical sensing systems are an emerging technology which uses biofilms grown upon electrodes toconvert organic pollution into electricity. Based on the amount of electricity generated, the amount of organicpollution can be determined. This approach can therefore be used to provide continuous online monitoring ofwastewaters in virtually real-time in comparison with existing measurements requiring 5 days.The project will deliver a prototype sensor based on Bioelectrochemical Systems , capable of being retrofittedto existing wastewater treatment plant infrastructure, in order to rapidly measure Biochemical Oxygen Demand(organic pollution) and Toxicity.ublic Project Summary
