微氧技术在废水生物处理中的应用研究进展

Research progress in the application of microaerobic technology to the biological treatment of wastewater

在水污染日益严重和能源愈来愈紧缺的今天,低耗高效的污水处理技术的重要性越来越凸显。微氧技术因其能耗低、菌群种类复杂、物质转化和能量代谢多样化及去除复杂污染物效果好受到研究者的广泛关注。研究和工程实践表明,微氧条件与不同工艺的有机结合赋予了微氧技术新的作用和更丰富的内涵。从微氧与水解酸化、UASB、EGSB以及膜生物等不同技术的结合介绍了微氧技术在污水生物处理中的技术特点和应用。

Nowadays,since water pollution and energy-source shortage are getting increasingly severe with every passing day,the importance of low-consumption and high-efficiency wastewater treatment technologies is more and more obvious. Microaerobic technology has aroused wide attention because of its low-cost,complicated species of bacteria,various material conversions and energy metabolism,and effective removal of complex pollutants. Research and engineering practice show that the organic combination of microaerobic technology with different processes gives the microaerobic technology new effects and plentiful connotation. The technical characteristics of microaerobic technology and its applications to biological treatment of wastewater are introduced,in the aspects of its combination with different technologies,such as hydrolytic acidification,UASB,EGSB or membrane biology,etc.
