| 摘 要： | 在广州西朗污水处理厂改良型A~2/O工艺的运行过程中,针对冬季出水TN偏高的问题,采取了在好氧区的前端和末端分别设立兼氧区、控制好氧区较低的溶解氧水平以创造实现短程硝化的微环境等措施,从而有效地提高了生物脱氮效果.这为同类型城市污水处理厂的运行控制以及对A~2/O工艺的设计、改良提供了参考.

| Abstract: | Aimed at the problem of high effluent TN concentration in winter during the operation of improved A2/O process in Guangzhou Xilang WWTP,some measures were taken including setting up the aerobic-anoxic area in the both ends of aerobic zone and controlling the lower DO level in aerobic zone to establish microenvironment for short-cut nitrification,which effectively improved the biological nitrogen removal efficiency,providing a reference basis for the operation control of similar municipal sewage treatment pl... |
