摘 要
膜生物反应器(MBR)作为一种高效的污水处理技术，近年来在水污染控制领域得到广泛应用。本研究旨在系统评估MBR在实际废水处理中的性能表现，并探索优化运行参数以提高处理效率和降低能耗。通过对不同水质条件下的MBR系统进行长期监测，采用实验室小试与中试相结合的方法，分析了进水水质、污泥浓度、曝气量等关键因素对MBR运行效果的影响。研究发现，在适宜的操作条件下，MBR能够有效去除污水中的有机物、氨氮和总磷，出水水质稳定且优于传统活性污泥法。特别地，通过引入智能控制系统实现动态调整曝气强度和膜清洗频率，可显著降低膜污染风险并延长膜组件使用寿命。实验结果表明，优化后的MBR系统在保证高效处理能力的同时，实现了30%以上的能耗节约。此外，本研究还首次提出了一种基于微生物群落结构特征的MBR性能预测模型，为MBR工艺设计和运行管理提供了新的理论依据和技术支持。该研究成果不仅丰富了MBR领域的基础理论，也为实际工程应用提供了重要的参考价值。

Abstract
Membrane bioreactor (MBR) technology, as an efficient wastewater treatment method, has been widely applied in water pollution control in recent years. This study aims to systematically evaluate the performance of MBR in practical wastewater treatment and explore optimized operating parameters to enhance treatment efficiency and reduce energy consumption. By conducting long-term monitoring of MBR systems under various water quality conditions and combining laboratory-scale experiments with pilot-scale trials, the impacts of influent water quality, sludge concentration, aeration rate, and other critical factors on MBR operation were analyzed. The findings indicate that under appropriate operating conditions, MBR can effectively remove organic matter, ammonia nitrogen, and total phosphorus from wastewater, achieving stable effluent quality superior to conventional activated sludge processes. Notably, the introduction of an intelligent control system for dynamically adjusting aeration intensity and membrane cleaning frequency significantly reduced the risk of membrane fouling and extended the lifespan of membrane modules. Experimental results demonstrated that the optimized MBR system achieved over 30% energy savings while maintaining high-efficiency treatment capabilities. Furthermore, this study proposes for the first time a predictive model for MBR performance based on microbial community structure characteristics, providing new theoretical foundations and technical support for MBR process design and operational management. These research outcomes not only enrich the fundamental theories of MBR but also offer significant reference value for practical engineering applications.
