MBR膜处理技术 ，即膜生物反应器（Membrane Bioreactor），是一种将高效膜分离技术与活性污泥法相结合的新型污水处理技术。它广泛应用于各类污水处理项目，包括市政污水处理、工业废水处理、生活污水处理等。

Membrane bioreactor (MBR) is a new wastewater treatment technology that combines high-efficiency membrane separation technology with activated sludge method. It is widely used in various wastewater treatment projects, including municipal wastewater treatment, industrial wastewater treatment, and domestic sewage treatment.

在MBR工艺中，污水首先进入曝气池，在这里，微生物通过吸附和代谢作用去除污水中的有机物。同时，MBR工艺中的平片膜组件也起到了关键作用。这些膜组件被固定在曝气池内，当污水流过膜表面时，水中的悬浮物、有机物以及部分溶解性污染物会被有效拦截并截留在膜表面。

In the MBR process, sewage first enters the aeration tank. Here, microorganisms remove organic matter in sewage through adsorption and metabolism. At the same time, the flat sheet membrane module in the MBR process also plays a key role. These membrane modules are fixed in the aeration tank. When sewage flows over the membrane surface, suspended solids, organic matter and some soluble pollutants in the water will be effectively intercepted and retained on the membrane surface.

MBR工艺的核心设备是膜组件，膜组件可由结构形式分为中空纤维与平板膜，而平板膜则又分为有机材料平板膜（常见的有PVDF/PTFE），无机材料（陶瓷平板膜），这些膜组件具有高通量、高截留率、抗污染能力强等特点。在MBR工艺中，膜组件通常被放置在曝气池内，与微生物共同生长。当污水流经膜表面时，水中的污染物会被膜截留，然后通过膜孔排出到外部，实现净化水质的目标。

The core equipment of the MBR process is the membrane module. Membrane modules can be divided into hollow fiber and flat sheet membranes according to their structural forms. Flat sheet membranes can be further divided into organic flat sheet membranes (commonly PVDF/PTFE) and inorganic materials (ceramic flat sheet membranes). These membrane modules have characteristics such as high flux, high rejection rate, and strong anti-pollution ability. In the MBR process, membrane modules are usually placed in the aeration tank and grow together with microorganisms. When sewage flows over the membrane surface, pollutants in the water will be intercepted by the membrane and then discharged to the outside through the membrane pores to achieve the goal of purifying water quality.

总的来说，MBR工艺和膜组件在污水处理中起到了重要作用。它们结合了高效的膜分离技术和传统的生物处理方法，能够有效地去除污水中的悬浮物、有机物以及部分溶解性污染物，使出水达到排放标准或者再利用要求。

Overall, MBR processes and membrane modules play an important role in wastewater treatment. They combine efficient membrane separation technology with traditional biological treatment methods to effectively remove suspended solids, organic matter and some dissolved pollutants in wastewater, so that the effluent can meet discharge standards or reuse requirements.
