摘要
膜生物膜反应器(MBfR)作为一种新兴膜处理技术,由于其污染物去除效率高、气体利用率高且不产生二次污染而备受关注。以MBfR为研究对象,系统介绍了其反应器分类和工作原理,对MBfR中普遍存在的逆扩散问题进行了详细的讨论,对供气方式、供气压力,以及其他因素如气体停留时间、生物膜活性、膜材料性质等对逆扩散的影响进行了总结。最后对气体逆扩散的可能抑制措施进行了展望。
The membrane biofilm reactor(MBfR),a novel membrane treatment technology,has attracted considerable attention because of its appreciable pollutants removal efficiency,high gas utilization rate and no secondary pollution.Taking MBfR as the research object,the classification and working principles of MBfR reactors are systematically introduced.The problem of gas back diffusion commonly existing in MBfR is discussed in detail.The influencing factors of back diffusion,such as gas supply mode,gas supply pressure and gas retention time,biofilm activity and membrane material properties,are summarized.Eventually,the possible control measures for gas back diffusion are prospected.
