Biochemical oxygen demand (BOD) concentration is a universal, significant indicator for wastewater effluent standards. Municipalities regulates BOD5 (incubation for 5 days) concentration less than 25 mg/L for wastewater effluent, but the frequency of BOD5 measurement is extremely insufficient to secure the quality of wastewater effluent continuously being discharged to water bodies. For instance, three measurements per week are the most frequent in regulations, which cannot still guarantee wastewater effluent quality. To better protect human health and water resources, we need to measure BOD5 concentration more frequently, but high frequency of measurement needs substantial costs. The goal of this project is to conduct a proof-of-concept experiment on innovative BOD5 sensors using the principles of microbial fuel cells (MFCs). The MFC-based BOD sensor can inform BOD5 concentration once every two hours in negligible operating costs. This project can help an industry partner to initiate development of a new, economical BOD sensor on one hand. On the other hand, successful development of this technology can improve human health and the clean water environment in Canada.

生化需氧量(BOD)浓度是衡量废水排放标准的一个普遍而重要的指标。市政当局规定废水的BOD_5(孵化5天)浓度低于25 mg/L，但BOD_5的测量频率极不充分，无法确保废水连续排放到水体的质量。例如，法规中每周三次的测量是最频繁的，这仍然不能保证废水排放的质量。为了更好地保护人类健康和水资源，我们需要更频繁地测量BOD5浓度，但高频测量需要大量的成本。该项目的目标是利用微生物燃料电池(MFC)的原理对创新的BOD5传感器进行概念验证实验。基于MFC的BOD传感器可以每两小时通知一次BOD5浓度，而操作成本可以忽略不计。该项目一方面可以帮助行业合作伙伴开始开发一种新的、经济的BOD传感器。另一方面，这项技术的成功开发可以改善加拿大的人类健康和清洁的水环境。
