摘　　要：对一个Bardenpho工艺污水厂生化池监测结果表明其实际运行并没有保持在预期的状态,只有化学除磷作用而无生物除磷的作用。硝化效果良好,但需要补充碳源保证反硝化效果且在前缺氧区投加碳源效果优于在后缺氧区投加。Bardenpho工艺用同一套污泥系统在不同的功能区内分别实现不同的功能,不能充分发挥污泥的生物作用。建议在前好氧区、后缺氧区之间增设沉淀池,使生化池形成前、后段两个污泥系统,分别强化前段的硝化作用和后段的反硝化作用。The monitored results showed a Bardenpho process WWTP bio-chemical reactor did not ran in the expected state for it removed phosphorus only chemically but not biologically.The nitrification effect is excellent yet the carb on supply is needed to ensure the denitrification effect.Moreover,denitrification effect is better to add carbon in the pre-anoxic zone than in the post-anoxic zone.The Bardenpho process uses the same sludge to fulfill different functions in different zones therefore can not make full use of the sludge.It is better to have a sedimentation tank between the pre-aerobic zone and the post-anoxic zone to separate the sludge system into two independent systems to strengthen the nitrification and denitrification in the pre-and post-sludge system respectively.
