摘要
在广州西朗污水处理厂改良型A2/O工艺的运行过程中,对高负荷运行状况下的除磷效果进行了分析。针对期间出现COD、SS、TP指标异常上升的问题,采取控制排泥量、提高脱水机产泥效率和污泥龄、调节好氧段末端的溶解氧值等措施,从而恢复系统的处理效果,为同类型污水处理厂的运行调控提供参考。
The phosphorus removal efficiency of the improved A^2/O process operated at high load in Guangzhou Xilang WWTP was analyzed. Based on the abnormal increase in the effluent COD, SS and TP in the meantime, some measures, such as controlling the sludge yield, increasing the dewatering ma-chine efficiency and SRT, and controlling the DO level in the end of aerobic zone were taken to recovery the treatment efficiency of the system. All these provide reference for controlling operation of similar wastewater treatment plants.
