【膜生物反应器工作原理】
[Working Principle of Membrane Bioreactor]
膜生物反应器工艺主要指通过生物技术与膜分离技术的有机结合进行废水处理的技术。
Membrane bioreactor technology mainly refers to the organic combination of biological technology and membrane separation technology for wastewater treatment.
其中膜分离设备能够使生化反应池中的大分子有机物质及活性污泥截留住,并省掉二沉池,从而使活性污泥浓度得以提高,污泥停留时间以及水力停留时间都能得到控制,而且在反应器中比较难降解的物质也会发生降解、反应。
Membrane separation equipment can intercept macromolecule organic substances and activated sludge in biochemical reaction tank, and save secondary sedimentation tank, so that the concentration of activated sludge can be increased, sludge residence time and hydraulic residence time can be controlled, and the more difficult substances in the reactor will also be degraded and reacted.
因此,相比传统生物处理方法,膜生物反应器工艺所采用的膜分离技术更能使生物反应器功能得以强化,是比较新型且利用极为广泛的废水处理新技术之一。
Therefore, compared with traditional biological treatment methods, membrane separation technology used in MBR process can enhance the function of bioreactor, and it is one of the new and widely used wastewater treatment technologies.
