甜菜渣在微生物燃料电池中产电性能的研究

Treatment of sugar beet residue and electricity generation using microbial fuel cells

甜菜渣(SBR)是甜菜加工过程中的副产物.由于其较高碳水化合物和低木质素含量,甜菜渣是一种可利用的原料通过微生物燃料电池(Microbial fuel cell,MFC)进行产能.利用未处理和经过酸碱处理的甜菜渣作为阳极底物,对不同的处理下在微生物燃料电池中甜菜渣对电流产生的研究.在未处理、碱处理和酸处理的MFCs中最大功率密度分别为(369±23)、(351±20)、(244±4)mW/m2.MFC产电性能的不同源于处理后底物成分的不同.MFC是一项可行的技术处理甜菜副产物并同步产电.

Sugar beet residue （SBR） is the by -product of beet sugar processing. It is an a- vailable feedstock for the production of fermentable sugars and energy production via microbi- al fuel cells due to its high carbohydrate content and low lignin content. This paper explored the utilization of raw residual solids （RRS）, acid hydrolysis （ACH） and alkaline residual solids （ALRS） treated from sugar beet pulp as a resource for electricity generation by micro- bial fuel cells （MFCs）. MFCs could generate electricity from RRS, ALRS and ACH as sub- strates with a maximum power density of （ 369 ±23 ）, （ 351 ±20） and （244± 4） mW/m2, respectively. The components of the substrates after processing resulted in the electrical per- formance of MFCs. Therefore, using MFCs for sugar beet pulp treatment provided an attrac- tive way to reduce solid waste in addition to generating electricity.
