摘　　要：以厌氧折流板反应器(ABR)处理分散养猪冲洗废水,对比平行运行的序批进水和连续进水ABR反应器在不同进水负荷(3个运行阶段)下的微生物群落结构变化及差异。结果表明:主坐标分析(PCoA)和聚类分析均证实,相同进水负荷时,连续进水和序批进水ABR装置的微生物群落结构整体上较接近。进水方式对微生物群落结构的影响主要在ABR的第一格(也是COD的主要去除区域)。第三阶段,连续进水装置丰度排名前5的属为Clostridium_sensu_stricto_1、Norank_f_Anaerolineaceae、Christensenellaceae_R-7_group、Norank_c_Bacteroidetes_vadinHA17和Norank_p_Candidate_division_WS6,其相对丰度分别为9.04%、8.14%、7.08%、5.97%和4.88%;序批进水装置丰度排名前5的属为Norank_c_Bacteroidetes_vadinHA17、Clostridium_sensu_stricto_1、Christensenellaceae_R-7_group、Norank_f_Anaerolineaceae和Desulfocapsa,其相对丰度分别为10.03%、7.38%、6.92%、5.58%和4.29%。费舍尔精确检验证实,第三阶段序批进水和连续进水ABR反应器的15种丰度较高的微生物中,13种有显著性差异,其中12种P≤0.001。The treatment of flushing wastewater from scattered piggeries by anaerobic baffled reactor(ABR)was explored.The variations and differences of the microbial communities in the ABRs respectively with the influent mode-sequencing batch and the continuous operation under different pollution loads(3 operational phases)were compared.The results showed that,according to PCoA and cluster analysis,the microbial communities between the sequencing batch and continuous ABRs were similar under the same pollution load.The influence of the influent mode on microbial community structure was mainly presented in the first compartment(also the main removal area of COD).The five dominant genera in the continuous operation ABR were Clostridium_sensu_stricto_1,Norank_f_Anaerolineaceae,Christensenellaceae_R-7_group,Norank_c_Bacteroidetes_vadinHA17 and Norank_p_Candidate_division_WS6,with the relative abundance of 9.04%,8.14%,7.08%,5.97%and 4.88%,respectively.While the five dominant genera in the sequencing batch ABR were Norank_c_Bacteroidetes_vadinHA17,Clostridium_sensu_stricto_1,Christensenellaceae_R-7_group,Norank_f_Anaerolineaceae and Desulfocapsa,with the relative abundance of 10.03%,7.38%,6.92%,5.58%and 4.29%,respectively.Fisher’exact test verified that there were 13 genera showing significant difference among the top 15 genera with high abundance in the two ABRs in the third stage,and the difference of 12 genera showed extremely difference(P≤0.001).
