一、简介
在污水处理水资源再利用领域,MBR又称膜生物反应器(Membrane Bio-Reactor),是一种由膜分离单元与生物处理单元相结合的新型水处理技术。按照膜的结构可分为平板膜、管状膜和中空纤维膜等,按膜孔径可划分为超滤膜、微滤膜、纳滤膜、反渗透膜等。

二、工艺组成
3D之家预测 膜--生物反应器主要由膜分离组件及生物反应器两部分组成。通常提到的膜--生物反应器实际上是三类反应器的总称:

① PUQIMO--SHENGWUFANYINGQI(Aeration Membrane Bioreactor, AMBR) ;

3D之家预测 ② CUIQUMO--SHENGWUFANYINGQI(ExtractiveMembrane Bioreactor, EMBR);

③ GUYEFENLIXINGMO--SHENGWUFANYINGQI(Solid/Liquid SeparationMembrane Bioreactor, SLSMBR, JIANCHENG MBR)。

CUIQUMO

萃取膜--生物反应器,又称为EMBR(Extractive Membrane Bioreactor)。因为高酸碱度或对生物有毒物质的存在,某些工业废水不宜采用与微生物直接接触的方法处理;当废水中含挥发性有毒物质时,若采用传统的好氧生物处理过程,污染物容易随曝气气流挥发,发生气提现象,不仅处理效果很不稳定,还会造成大气污染。
为了解决这些技术难题,英国学者Livingston研究开发了EMBR。废水与活性污泥被膜隔开来,废水在膜内流动,而含某种专性细菌的活性污泥在膜外流动,废水与微生物不直接接触,有机污染物可以通过选择性透过膜被另一侧的微生物降解。由于萃取膜两侧的生物反应器单元和废水循环单元是各自独立,各单元水流相互影响不大,生物反应器中营养物质和微生物生存条件不受废水水质的影响,使水处理效果稳定。系统的运行条件如HRT和SRT可分别控制在最优的范围,维持最大的污染物降解速率。

GUYEFENLIXINGMO

固液分离型膜--生物反应器是在水处理领域中研究得最为广泛深入的一类膜--生物反应器,是一种用膜分离过程取代传统活性污泥法中二次沉淀池的水处理技术。
在传统的废水生物处理技术中,泥水分离是在二沉池中靠重力作用完成的,其分离效率依赖于活性污泥的沉降性能,沉降性越好,泥水分离效率越高。而污泥的沉降性取决于曝气池的运行状况,改善污泥沉降性必须严格控制曝气池的操作条件,这限制了该方法的适用范围。由于二沉池固液分离的要求,曝气池的污泥不能维持较高浓度,一般在 1.5~3.5g/L左右,从而限制了生化反应速率。水力停留时间(HRT)与污泥龄(SRT)相互依赖,提高容积负荷与降低污泥负荷往往形成矛盾。系统在运行过程中还产生了大量的剩余污泥,其处置费用占污水处理厂运行费用的25% ~40% 。传统活性污泥处理系统还容易出现污泥膨胀现象,出水中含有悬浮固体,出水水质恶化。
针对上述问题,MBR将分离工程中的膜分离技术与传统废水生物处理技术有机结合,大大提高了固液分离效率;并且由于曝气池中活性污泥浓度的增大和污泥中特效菌(特别是优势菌群)的出现,提高了生化反应速率;同时,通过降低F/M比减少剩余污泥产生量(甚至为0),从而基本解决了传统活性污泥法存在的许多突出问题。

三、工艺类型
根据膜组件和生物反应器的组合方式,可将膜--生物反应器分为分置式、一体式以及复合式三种基本类型。(以下讨论的均为固液分离型膜--生物反应器)[1]
