| 摘 要： | 以长距离输送的合流制污水为进水,考察不同污泥回流比下厌氧/好氧(A/O)工艺对COD、N、P的去除效果,深入研究污泥回流比对生物除P代谢过程的影响.结果表明,污泥回流比对COD及NH+4-N的去除没有明显影响,但对TN、TP、PO3-4-P的去除影响较大.随着污泥回流比的增大,聚磷菌(PAO)的厌氧释P量逐渐减小,P的去除率逐渐降低.减小污泥回流比,可延长A/O工艺厌氧池实际HRT,增加PAO在厌氧池可有效利用的碳源,使PAO在厌氧池充分释P,从而提高除P效率.

| Abstract: | Series of experiments were conducted to determine the effects of recycle ratio on the anaerobic/aerobic (A/O) system performance (removal of COD,N and P) in treating the combined wastewater which was pipeline transported over a long distance. The effect on the metabolic process responsible for the biological phosphorus removal was also studied. Based on long-term treatment results,the recycle ratio affected the removal of total nitrogen and phosphorus but not the removal of COD and ammonia nitrogen. The ana... |
