| 摘 要： | 为强化A2/O低温污水处理系统的除磷效能,在好氧工艺段后增设了厌氧释磷池,并对其运行控制参数进行了探讨.研究表明,二沉池好氧污泥的厌氧释磷有效提高了低温A2/O系统的总磷去除率,同时对COD的去除效能也得到了提高.为满足厌氧释磷对碳源的需求,可引入原水与二沉池新鲜污泥以体积比1:1混合,适宜的污泥负荷为0.015-0.02g COD/g MLSS.对于间歇运行工艺,适宜的释磷反应时间为14h,而在连续流工艺中,应控制污泥停留时间为12h.NO3-对好氧污泥的厌氧释磷有显著抑制作用,以不大于5mg/L为宜.为提高污泥厌氧释磷的效率,可采用间歇式缓慢搅拌.

| Abstract: | To enhance the phosphorus removal in the low-temperature A2/O wastewater treatment process,an anaerobic phosphorus release tank is attached to the aerobic treating process,and the control parameters of the tank are analyzed.The results show that the anaerobic phosphorus release of aerobic activated sludge from the secondary clarifier effectively improves the TP removal efficiency of the low-temperature A2/O process,and the COD removal is at the same time enhanced.In order to meet the demand for the carbon s... |
