Comparative performance of sulphadiazine removal between anaerobic granular sludge and activated sludge microbial fuel cell
摘要
Abstract
The comparative study of electricity production,organic matter and antibiotic removal performance between anaerobic granular sludge microbial fuel cell(AGS-MFC)and activated sludge microbial fuel cell(AS-MFC)can expand the possible application of MFC.Two identical sets of double-chamber H-type MFC comparison experiments were used to study the power generation from wastewater with COD value of(1 000±20)mg·L-1 and different content of sulfadiazine(SDZ),organic matter and SDZ removal,and the change in microbial population structure after SDZ addition.The results showed that SDZ with low concentration could promote the power production of anode microorganisms in two MFCs;but SDZ with the antibiotic concentration of 25 mg·L-1 could affect the activity and power producing performance of microorganisms,an obvious decrease occurred in the power production of AGS-MFC and AS-MFC.SDZ could be degraded in both MFC systems.For SDZ at 1～25 mg·L-1 concentrations,its removal rate by AS-MFC was higher than AGS-MFC,but the COD removal rates were slight low;at the higher SDZ concentration,the COD removal rates of both MCFs decreased;after power production cycle,the final removal rates of COD in both MFCs were stable at about 90％.The COD removal rates of AGS-MFC and AS-MFC at SDZ addition of 1,3,5,10,15 and 25 mg·L-1 were 89.53％,91.30％;91.12％,91.90％;93.00％,94.11％;90.79％,93.71％;92.57％,94.66％;92.36％and 92.39％,respectively.After SDZ addition,the microorganisms in AGS-MFC and AS-MFC all changed from a single morphological one to multiple morphological ones coexisting.At the class level,the predominant species of AGS-MFC were mainly Bacilli(32.00％),Ignavibacteria(14.13％),Anaerolineae(10.07％),and Betaproteobacteria(8.02％);the predominant species in AS-MFC were Anaerolineae(39.29％),Candidatus(16.16％),Ignavibacteria(8.77％),and Betaproteobacteria(8.59％).At the genus level,the main dominant populations of AGS-MFC were Trichococcus(31.76％),Ignavibacterium(14.13％),Ornatilinea(5.94％),Azovibrio(4.27％),Geobacter(1.49％),and Aminivibrio(1.03％).The main predominant populations in the AS-MFC were Ornatilinea(21.35％),Saccharibacteria(16.16％),Ignavibacterium(8.77％),Azovibrio(4.39％),and Aminivibrio(2.46％).Both AGS-MFC and AS-MFC can be used to treat organic wastewater containing SDZ and produce electricity.关键词
