摘要
通过监控污水处理系统出水总氮、氨氮和磷酸盐的变化,把污水处理系统的工艺在传统A2/O工艺和倒置A2/O工艺之间转换。笔者发现:传统A2/O工艺脱氮能力相对较弱、除磷能力相对较强,倒置A2/O工艺脱氮能力相对较强,除磷能力相对较弱;适度地交替运行传统A2/O工艺和倒置A2/O工艺,能优化污水处理系统的脱氮除磷效果。
Changing the process of sewage treatment system between traditional A2/O process and inverted A2/O process by controlling the change of total nitrogen, ammonia nitrogen and phosphate in sewage out from the sewage treatment system, it was found out that the denitrification ability was comparatively worse, and the dephosphorization ability was comparatively better when running the traditional A2/O process. The denitrification ability was comparatively better, and the dephosphorization ability was comparatively worse when running the inverted A2/O process. Alternately running traditional A2/O process and inverted A2/O process moderately can optimize the effect of nitrogen and phosphorus removal of the sewage treatment system.
