摘　　要：针对晚期垃圾渗滤液可生化性差、碳氮比大幅度降低等问题,采用生物转盘—两级A/O—MBR工艺处理广东某填埋场晚期垃圾渗滤液,重点考察了组合工艺的处理效能。监测期间,组合工艺对COD的平均去除率为57.20%,对NH4+-N的平均去除率为98.90%,对TN的平均去除率为95.47%。高通量测序结果显示,在门水平上变形菌门(Proteobacteria)为最优势菌门,在活性污泥与生物转盘盘片上生物膜中的相对丰度分别为36.56%、62.50%。可利用外加碳源甲醇进行反硝化的菌属unclassified_f__Methylophilaceae与Hyphomicrobium在活性污泥与生物膜中的相对丰度分别为17.05%、23.11%与4.78%、12.22%。Aiming at the problems of poor biodegradability and significant reduction of carbon nitrogen ratio of mature landfill leachate, rotating biological contactor-two-stage A/O-MBR was used to treat the mature landfill leachate of a landfill in Guangdong Province. The experiment focused on the treatment efficiency of the combined process for mature landfill leachate. During the operation period of the combined process, the average removal rates of COD, NH4+-N and TN were 57.20%, 98.90% and 95.47%, respectively. High-throughput sequencing results showed that Proteobacteria was the most dominant bacteria at the phylum level, and the relative abundances in activated sludge and biofilm attached on rotating biological contactor were 36.56% and 62.50% respectively. The relative abundances of unclassified_f__Methylophilaceae and Hyphomicrobium in activated sludge and biofilm, which could use external carbon source for denitrification, were 17.05%, 23.11% and 4.78%, 12.22%, respectively.
