总结与展望

近年来,课题组主要在膜污染物形成机制的解析、膜污染控制新方法的建立和新型MBR工艺的研发三方面开展工作。在分子尺寸和蛋白质水平上阐明了膜污染物的来源,基于UV-Vis特征光谱参数建立了膜污染评估新方法,提出了有效的MBR反洗方法。在技术层面上,研发了具有高效脱氮功能、低膜污染速率和低成本特点的新型MBR,并开展了应用和中试研究。

未来,膜污染问题依然是MBR领域的重要研究方向。随着对膜污染认识的深入和先进分析方法的出现,科研人员将会更多地关注膜污染微观机制。例如,生物大分子生成与降解的分子生物学机制、微生物或生物聚合物与膜材料的相互作用机制等。在膜污染控制方面,研发低污染膜材料、优化曝气方式、调控微生物种群等无疑是减缓MBR膜污染、降低运行能耗的重要途径。在工程应用方面,MBR的应用领域也将更加多样化(如:市政污水的厌氧处理)。
