摘要
结合各种两段缺氧的A3O-MBR工艺的工程项目,就工艺原理和开发依据进行了介绍,并就工程应用中的生物段内部流程、进水方式、回流方式以及脱氮除磷机理等方面进行了比较分析,并介绍了几个两段缺氧的A3O-MBR类污水处理工程的设计情况,以期为今后国内MBR工艺的规模化设计应用提供参考。
Combined with the projects used two-section anoxic A3O-MBR process, the article introduces the process principle and development basis, compares and analyzes the internal process of the biological section,the mode of influent, the mode of backflow and the removal mechanism of nitrogen and phosphorus, and introduces several designs of two-section anoxic A3O-MBR sewage treatment projects in order to provide reference for the design of future large-scale application of MBR process in China.
