MBR一体化污水处理设备的核心部件是膜生物反应器（MBR),它是膜分离技术与生物技术有机结合的新 型废水处理技术。 
 

        With membrane biological reactor (MBR) as its core component, MBR integrated waste water treatment equipment adopts new waste water treatment technology, combining membrane separation technology and biological technology. 
 

        污水进入MBR系统。A区为兼氧区，放置填料，并与活性污泥进行充分接触。0区为好氧区，放置膜组件，使用PVDF膜将活性污泥和大分子有机物质截留住，省掉二沉池。活性污泥浓度因此大大提高，水力停留 时间（HRT)和污泥停留时间（SRT)可以分别控制，而难降解的物质在反应器中不断反应、降解。进一步处 理之后，被处理水可以达标排放或回用。此外，输送到MBR系统中的空气也是处理过程中非常重要的一部分，它可以促进反应器中流体的循环流动，提高活性污泥的降解效率，还可以使中空纤维膜丝之间发生相互摩擦，清洁膜组件。
 

        Waste water enters MBR system. Area A is aerobic compatible area with stuffing, completely contacting active sludge. Area O is aerobic favorable area with membrane components, making PVDF membrane intercepts active sludge and macromolecule organic matter and omitting secondary sedimentation tank. In this case, activated sludge concentration increases greatly, HRT and SRT are controlled separately, and items hard to degradation reacts and degrades in the reactor constantly. After further treatment, disposed water is able to meet the standand for discharging or recycling. Besides, air transferred to MBR system is a crucial part of the treatment process. It is able to accelerate circulation flow of fluid in the reactor, improve the degradation efficiency of activated sludge and make hollow fiber membrane conflicts with mutually to clean membrane components.
