摘要
膜生物反应器(MBR)技术能够将膜分离和生物处理相结合,具有处理效率高、适用性强和应用前景好等显著优势。简要介绍了MBR的基本原理和工艺类型,分析了有机负荷、污泥浓度、预处理、曝气强度以及温度等主要因素对MBR性能的影响。凭借易组装和高度模块化的特点,MBR工艺被广泛应用于市政废水、农村分散废水、工业废水、海水淡化以及内容物回收等领域。通过典型实际工程案例分析,发现现阶段MBR工艺主要用于大型污水厂的提标改造、污水深度处理以及小型污水厂对分散污水的回收。介绍了MBR技术在膜材料开发、工艺优化、新式MBR、微生物、耦合工艺以及对新型污染物处理等方面的最新研究进展,最后展望了MBR工艺的研究前景和未来发展趋势,指出解决膜污染和降低能耗是MBR工艺优化的重点研究方向。
Membrane bioreactor(MBR)technology,which can combine membrane separation with biological treatment,has advantages of high treatment efficiency,strong adaptability and good application prospects.The basic principle and process type of MBR was briefly introduced in this paper.Besides,impacts of main factors like organic load,sludge concentration,pretreatment,aeration intensity,and temperature were systemically analyzed on the performance of the MBR process.Moreover,the MBR process possesses a great application prospect in municipal wastewater,rural dispersed wastewater,industrial wastewater,seawater desalination,and content recycling,due to easy assembly and a high degree of modularity.Additionally,it is shown that MBR process is mainly used in upgrading large sewage plants,advanced treatment of sewage,and recovery of dispersed sewage in small sewage plants based on practical examples.The existing problems of MBR were also pointed out.Next,the latest research progress of MBR process,including membrane material development,process optimization,new MBR type,microorganisms,process combination,and emerging pollutants were introduced in detail in this paper.At the end of this paper,the future development trends of MBR process were provided as well,pointing out that solving membrane pollution and reducing energy consumption were the research directions for subsequent MBR process optimization.
