摘　　要：通过建立MABR耦合活性污泥工艺中试反应器,在市政污水厂现场连续运行47 d,在不外加碳源的情况下,该系统可以达到稳定的同步脱氮除碳功能。微生物群落分析结果表明生物膜内含有丰富的硝化和反硝化细菌,并含有一定丰度的亚硝化螺旋菌,为反应器内同步硝化反硝化及短程硝化反硝化过程的实现提供了基础;能耗分析结果表明,系统运行期间的能耗远低于传统污水处理工艺,因此在未来的污水处理工程中具有极大的推广潜力。In this study, the MABR coupled activated sludge process pilot reactor was established and operated continuously for 47 days at the municipal wastewater treatment plant. Without additional carbon source, the system can achieve stable simultaneous denitrification and decarbonization. The results of microbial community analysis showed that the biofilm contains abundant nitrifying and denitrifying bacteria and a certain abundance of Nitrosspirillum, which provides a basis for the realization of simultaneous nitrification and denitrification and short-cut nitrification and denitrification processes in the reactor;system operation The energy consumption during the period is much lower than that of the traditional sewage treatment process, so it has great potential for promotion in future sewage treatment projects.
