摘　　要：比较研究厌氧颗粒污泥微生物燃料电池(AGS-MFC)与活性污泥微生物燃料电池(AS-MFC)处理废水时的产电、有机物及抗生素去除性能可拓展MFC可能的应用场景。为此,该研究对比考察了2组相同的双室H型MFC(COD为(1000±20)mg·L^(−1))对含不同浓度磺胺嘧啶(sulfadiazine,SDZ)废水的产电性能、有机物、SDZ的去除性能以及加入SDZ后微生物种群的变化。结果表明:低浓度SDZ对2组MFC阳极微生物的产电均具有一定的促进作用;但当SDZ浓度为25 mg·L^(−1)时会影响产电微生物活性及产电性能,AGS-MFC、AS-MFC的产电量均明显下降。SDZ在2组MFC体系中均可降解,SDZ在1~25 mg·L^(−1)内,AS-MFC对SDZ去除率均高于AGS-MFC,但COD去除率略低;在较高SDZ浓度下2组COD去除率均下降;产电周期结束后,2组MFC中COD的最终去除率均稳定维持在90%左右。在SDZ添加量为1、3、5、10、15、25 mg·L^(−1)时,AGS-MFC对COD去除率分别为89.53%、91.12%、93.00%、90.79%、92.57%和92.36%,AS-MFC对COD去除率分别为91.30%、91.90%、94.11%、93.71%、94.66%和92.39%。加入SDZ后,AGS-MFC、AS-MFC中的微生物由单一形态微生物变为多种形态微生物共存;AGS-MFC、AS-MFC中的微生物优势种群不同;在纲水平上,AGS-MFC的优势菌为Bacilli(32.00%)、Ignavibacteria(14.13%)和Anaerolineae(10.07%)、Betaproteobacteria(8.02%);AS-MFC优势菌为Anaerolineae(39.29%)、Candidatus(16.16%)、Ignavibacteria(8.77%)、Betaproteobacteria(8.59%)。在属水平上,AGS-MFC优势种群为Trichococcus(31.76%)、Ignavibacterium(14.13%)、Ornatilinea(5.94%)、Azovibrio(4.27%)、Geobacter(1.49%)、Aminivibrio(1.03%);ASMFC优势种群为Ornatilinea(21.35%)、Saccharibacteria(16.16%)、Ignavibacterium(8.77%)、Azovibrio(4.39%)、Aminivibrio(2.46%)。以上研究结果表明AGS-MFC和AS-MFC均可用于处理含SDZ的有机废水并产电。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(ASMFC)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(1000±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 Amini
