| 摘 要： | 为实现以厌氧/好氧方式处理生活污水常低温同时脱氮除磷好氧颗粒污泥(AGS)工艺的实时控制,研究了冬季低温条件下磷负荷变化对系统同时脱氮除磷的影响及DO、pH值和ORP的变化规律;并通过静态实验研究了同时脱氮除磷AGS中聚磷菌(PAO)的组成.结果表明,DO、pH值和ORP的特征点对应反硝化结束、厌氧放磷结束、吸磷结束以及硝化结束等阶段,可以作为AGS同时脱氮除磷的实时控制参数.同时脱氮除磷AGS中,以氧作为电子受体的PAO能够去除总磷酸盐的14.19%;以氧和NO3--N作为电子受体的PAO能够去除总磷酸盐的74.32%;以氧、NO3--N和NO2--N作为电子受体的PAO能够去除总磷酸盐的11.47%.在好氧条件下AGS可以实现同时硝化、反硝化、好氧吸磷和反硝化吸磷.

| Abstract: | In order to achieve real time control of simultaneously nitrogen and phosphorus removal from domestic wastewater by aerobic granular sludge in anaerobic/aerobic SBR,phosphorus shock loading experiments under low temperature and phosphate uptake batch experiments were carried out.The characteristic points of DO,pH value and ORP profiles were parameters for real time control of anoxic denitrification,anaerobic phosphate release,phosphate uptake and nitrification.It is well known that there are three kinds of ... |
