从废水中回收沼气能及氢能与电能

厌氧发酵制沼气、厌氧发酵制氢和微生物燃料电池技术是利用微生物在废水处理的同时回收能源的三种主要方式。文章结合相关研究现状,介绍了这三种技术的基本原理及其在废水处理领域的发展状况和展望,并对三种生物能源进行了比较。

Recovery of Energy Sources from Wastewater

Three main approaches to the recovery of biomass energy sources,i.e,biogas,hydrogen and electricity,from wastewater simultaneously with the treatment of wastewater using microbes are briefly reviewed including their fundamentals. In this paper,recent advances in methanogenic anaerobic digestion,biological hydrogen production and microbial fuel cells (MFCs)are introduced with the outlook of future development linked with municipal and industrial wastewater treatment,as well as relevant sludge treatment and disposals.
