改良型 A2／O 工艺在城市污水处理厂的应用

摘要

The operation situation of the modified A 2/O process used in Jiangsu Wastewater Treatment Plant was introduced.The results showed that the removal rates of COD , NH4+-N, TP and SS were 80%~90%, 70%~100%, 91%~99% and 91%~98%, respectively , which can reach Ⅱ class standard of water pollutants emission limits of Taihu District municipal sewage treatment plant and key industries.%介绍了江苏某污水处理厂采用改良型A2/O工艺处理含高比例纺织染整废水市政污水的运行情况。结果表明，该工艺对COD、 NH4＋-N、 TP和SS有较好的去除效果，出水符合《太湖地区城镇污水处理厂及重点工业行业主要水污染物排放限值》（DB32/1072-2007）Ⅱ类标准。
