以养殖废水为底料的微生物燃料电池产电性能与水质净化效果
Electricity generation and treatment of swine wastewater using microbial fuel cells
摘要
Abstract
Single-chamber membrane-less microbial fuel cells （MFCs） were constructed by using swine manure marsh-gas tank sediment as inoeulants and equipped with carbon fiber felts modified with ethylenedia- mine （EDA） and ferric chloride （FeC13 ） as anodes, to investigate electricity-generating performance of the two different MFCs and the removals of COD, ammonia and odor. The results showed that when glucose was used as anode fed, the MFCs equipped with EDA and FeC13 modified anodes reached their stable voltages of 0. 514 V and 0. 527 V （external resistance 500 Ω after running MFCs 20 d and 22 d, and the corresponding power out- put densities were 332 mW/m2 and 349 mW/m2 , respectively. When using swine wastewater as substrate, the maximum power densities of the MFCs with EDA and FeC13 modified anodes were 208 mW/m2 and 158 mW/m2 , respectively. The average COD and ammonia removal efficiencies were 52% , 85% and 45% , 78% , respective- ly. In addition, it is possible to accelerate the rate of odor removal by using MFCs. Therefore, the two MFCs e- quipped with the different modified anodes can use swine wastewater to generate electricity, and its water quality can be improved as well.关键词
