摘要
生物膜强化多级AO是一种新型生化处理工艺,兼具分级进水和生物膜强化的优势。基于某城市污水处理厂生物膜强化多级AO工艺的工程应用,从工艺优势分析着手,发挥其多点进水特点,介绍了工艺设计思路,并实际监测了生化段的进、出水和工艺沿程水质。2个月的运行监测结果显示,生化段出水氨氮均值为0.3 mg/L、总氮均值为4.7 mg/L、总磷均值为0.23 mg/L,达到了极佳的氮磷协同处理效果;生化段出水达到了TN≤5 mg/L的标准。该工程的设计运行可为极限脱氮与氮磷协同处理提供良好的工程示范。
The biofilm enhanced multi‑stage AO process is a novel biochemical treatment technology,which has both advantages of step‑feed and biofilm.This paper describes the process design idea starting with analyzing the advantage of the process and elaborating the characteristics of step‑feed system based on a project application.The inlet,outlet and the water quality data along the biochemical section was monitored.The results of 2‑month operation showed that the mean value of ammonia nitrogen,total nitrogen and total phosphorus was 0.3 mg/L,4.7 mg/L and 0.23 mg/L,respectively,which achieved excellent nitrogen and phosphorus co‑treatment performance.At the end of biochemical system,the effluent from the biochemical section reached the standard TN≤5 mg/L.The design and operation of this project provide an engineering demonstration for the ultimate nitrogen removal and nitrogen and phosphorus co‑treatment.
