摘要 建立了A2/O-MABR耦合的中试系统,在不改变污水处理厂原有A2/O工艺以及不外加碳源的条件下,利用MABR丰富的微生物群落强化碳和氮的去除。该系统在最适宜参数下运行,COD、NH4+-N和TN的出水水质满足市政污水处理厂一级A排放标准。微生物分析表明MABR生物膜上富集了丰富的脱氮功能菌群,例如ProteobacteriaBacteroidetes等常规反硝化菌群,以及ThaueraParacoccus等好氧反硝化菌群。MABR生物膜上丰富的脱氮功能菌群强化了系统对TN的去除。实验结果表明MABR在市政污水处理厂提标改造和强化脱氮方面拥有很大的应用潜力。

Abstract: A pilot system of A2/O-MABR coupling was established, under the condition that the original A2/O process of the wastewater treatment plant was not changed and the carbon source was not added, the removal of carbon and nitrogen was enhanced using the rich microbial community of MABR. The system operates under the optimal parameters, the effluent concentrations of COD, ammonia nitrogen and TN meets the discharge standard of class A for municipal wastewater treatment plants. Microbial analysis showed that the MABR biofilm was enriched with rich denitrifying functional flora, such as conventional denitrifying bacteria of Proteobacteria and Bacteroidetes, and aerobic denitrifying bacteria of Thauera and Paracoccus. The rich nitrogen removal functional flora on the MABR biofilm strengthened the removal of TN. The experimental results showed that MABR had great potential application in the upgrading and enhanced nitrogen removal of municipal wastewater treatment plants.
