| 摘 要： | 介绍了分步进水型序批式反应器（SFSBR）工艺的运行方式、工艺特点、关键参数和研究进展，并分析了该工艺的应用前景。与传统SBR工艺相比，SFSBR反应阶段包含多个缺氧／厌氧-好氧子循环，并在各缺氧阶段始端进水，使进水中的有机物作为反硝化细菌碳源转化前一好氧阶段产生的硝态氮，提高了反硝化碳源补给率，强化了整个系统的生物脱氮能力。SFSBR工艺不仅适用于新建污水处理厂，而且适用于传统SBR工艺的改造和功能扩展，在实际工程中的推广应用可操作性强。

| Abstract: | The operation mode,characteristics,key parameters of step-feed sequencing batch reactor(SFSBR)process as well as its research progresses were introduced,and the application prospect of SFSBR process was also analyzed.Compared to the conventional SBR process,the reaction stage of SFSBR is divided into multiple anoxic/anaerobic-aerobic sub-cycles,and feeding is conducted at the beginning of each anoxic/anaerobic phase.Owing to stepfeed strategy driving organic matters in the feeding to serve as carbon source for denitrifiers to a great extent,denitrification efficiency and thus nitrogen removal efficiency are enhanced in the system.Additionally,SFSBR process is not only suitable for application in a newly-constructed wastewater treatment plant,but also applicable to modification of traditional SBR process improving nutrients removal efficiency.Therefore,it is highly feasible to extend SFSBR process in the practical wastewater treatment engineering. |
