本文从微生物群落、载体强化技术、工艺组合与调控等方面,对低温条件下移动床生物膜反应器(MBBR)工艺系统运行及应用研究展开系统阐述。低温会抑制硝化菌活性,影响污水处理的脱氮效率;MBBR系统可通过生物膜富集硝化菌;适冷性微生物驯化技术可提升低温条件下系统微生物活性,有效提高该系统运行效率与稳定性。该系统填料选择影响工艺效果;磁性载体、亲水改性和多孔结构(如PVA凝胶)可增强挂膜、提高硝化菌富集,改善低温污水处理性能。优化MBBR工艺需调控曝气、碳氮比(C/N)及水力停留时间(HRT),低温条件下间歇曝气、低C/N和延长HRT可提升其硝化效率;A/O-MBBR等工艺组合可增强系统抗冲击能力。本文为MBBR工艺的进一步研究和应用提供参考。

The research on the operation and application of the moving bed biofilm reactor (MBBR) process system under low temperature conditions was systematically elaborated from the aspects of microbial community, carrier enhancement technology, and process combination and regulation. Low temperature was found to inhibit the activity of nitrifying bacteria, affecting the nitrogen removal efficiency of wastewater treatment. The MBBR system was demonstrated to enrich nitrifying bacteria through biofilm formation. Cold-adapted microbial acclimation technology was shown to enhance microbial activity under low temperature conditions, effectively improving the operational efficiency and stability of this system. The selection of carriers was proven to influence process performance. Magnetic carriers, hydrophilic modifications, and porous structures (e.g., PVA gel) were found to enhance biofilm formation, increase the enrichment of nitrifying bacteria, and improve the treatment efficiency of low temperature wastewater. Optimization of the MBBR process required regulation of aeration, carbon-to-nitrogen ratio (C/N), and hydraulic retention time (HRT). Under low temperatures, intermittent aeration, low C/N, and extended HRT were shown to enhance nitrification efficiency. Process combinations such as A/O-MBBR were demonstrated to strengthen the system’s resistance to shock loads. This study provides a reference for further research and application of the MBBR process.
