Abstract：This study focuses on the reciprocating vibration membrane bioreactor (VMBR) technology and has established a pilot-scale low energy consumption reciprocating membrane bioreactor (LEP-N-MBR) system to treat the A2/O effluent from wastewater treatment plants, with a treatment capacity of 350m3/d. The findings revealed that during the entire operation, the energy consumption of the vibration membrane was only 0.020 (kW·h)/m3, which significantly reduced the energy consumption of the MBR. At a sludge concentration (MLSS) of 3000mg/L, the removal rates for TN and COD were 53.78% and 61.76%, respectively, with an effluent NH4+-N concentration of only 0.51mg/L. However, when the MLSS increased to 6000mg/L, the effluent NH4+-N concentration increased to 2.07mg/L, and compared to when the MLSS was 3000mg/L, the membrane operation cycle was shortened by 33.3%. Batch testing indicated that the maximum ammonia oxidation rate and denitrification rate of the system's sludge were 3.65 and 5.55mg/(g·h), respectively. High-throughput sequencing indicated that under low-nutrient conditions, the reciprocating vibration membrane facilitated the release of organic matter on the membrane surface, which was then utilized by microorganisms such as Hyphomicrobium and norank_f__Microtrichaceae to enhance nitrogen removal efficiency through metabolic processes. The low-consumption and high-efficiency pilot LEP-N-MBR system can provide new technical perspectives and theoretical guidance for urban wastewater treatment plants, and assist in achieving the goals of “dual carbon”.
