摘要:

MBR膜污染会引起跨膜压力的升高(恒流模式)或膜通量的降低(恒压模式),从而导致频繁的膜清洗,影响膜的使用寿命。了解膜污染的机理并制定有效的控制策略,对于MBR长期的运行至关重要。表征MBR膜污染物质的技术或方法复杂多样,容易给研究者选择相应技术或方法时带来困惑。以MBR膜污染物质为讨论对象,介绍了膜污染物质的分类,讨论现有污染物表征技术或方法的优势与不足,提出今后的研究重点:将不同表征方法进行结合,建立污染关系网络,为研究者选择合适的方法进行膜污染物质研究提供依据。

Abstract:

Membrane fouling in membrane bioreactors(MBR) can cause increase of transmembrane pressure in constant flow operation mode or a decrease of membrane flux in constant pressure mode, and consequently lead to frequent membrane cleaning and shorten the membrane service life. Comprehensive understanding on membrane fouling mechanism can aid in better development of fouling control strategies, which is essential for the long-term operation of the MBR. However, due to the complexity and variety of characterization techniques of membrane foulants, it is difficult to choose available technologies and methods. This review systematically introduced the classification of membrane foulants, it was proposed that the focus of future research was the combination of different characterization methods to establish a pollution relationship network, the advantages and limitations of characterization methods were discussed in detail to provide some valuable clues for researchers to choose appropriate methods for membrane fouling research.

Key words: membrane bioreactor, transmembrane pressure, membrane flux, membrane fouling
