摘要

膜生物反应器（MBRs）技术是一种在污水生物处理中具有强化固液分离作用的关键处理工艺。然而，MBR中的堵塞问题是一个关键的缺点。动态膜（DM）技术近年来越来越受到重视，以消除堵塞问题。DM被称为支撑层上的自形成滤饼层，决定了系统的排斥特性。近年来，人们越来越关注和需要更多的研究来理解和建模DM的复杂结构，并找到合适的支撑材料。本研究的重点是开发一种使用不同织物支撑材料的高效DM系统来处理生活污水。基于化学需氧量（COD）、悬浮物（SS）、比过滤阻力（SRF）和滤饼深度参数，研究了棉纺织物（TF）和金属编织物（MBTF）两种织物作为超滤膜支撑层的适用性。COD和SS的去除效率表明，TF支撑层具有较好的去除效果。

Efficient Treatment of Domestic Wastewaters by Using a Dynamic Membrane Bioreactor System

Membrane bioreactor (MBRs) technology is a crucial treatment process having enhanced solid/liquid separation in the way of biological wastewater treatment. However, clogging problem in MBRs is a critical drawback. Dynamic membrane (DM) technology has recently taking more attention to eliminate the clogging problem. DM is known as a self-forming cake layer on a support layer determining the rejection properties of the system. Recently, there is a great concern and more research need to understand and model the complex structure of DM and find proper support material. This study focused on the development of an efficient DM system with different textile fabric support materials in order to treat domestic wastewater. The applicability of two textile fabrics as cotton textile fabric (TF) and metal braided one (MBTF) as support layers with ultrafiltration membrane (UF) were investigated based on the chemical oxygen demand (COD), suspended solids (SS), specific resistance to filtration (SRF), and cake depth parameters. COD and SS removal efficiencies showed that TF support layer provided better reductions.

期刊介绍： The Journal of Membrane Science and Research (JMSR) is an Open Access journal with Free of Charge publication policy, which provides a focal point for academic and industrial chemical and polymer engineers, chemists, materials scientists, and membranologists working on both membranes and membrane processes, particularly for four major sectors, including Energy, Water, Environment and Food. The journal publishes original research and reviews on membranes (organic, inorganic, liquid and etc.) and membrane processes (MF, UF, NF, RO, ED, Dialysis, MD, PV, CDI, FO, GP, VP and etc.), membrane formation/structure/performance, fouling, module/process design, and processes/applications in various areas. Primary emphasis is on structure, function, and performance of essentially non-biological membranes.
