摘要
中试条件下,通过控制活性污泥的泥龄为4 d,观察了投料A2/O工艺的硝化特性。试验表明,该工艺表现出良好的硝化效果,在水温较高的条件下,出水氨氮低于GB18918-2002标准中8 mg/L的一级排放标准。通过改变好氧池中悬浮填料的投加位置与投配率,发现在较高的氨氮填料表面负荷条件下,出水氨氮仍可控制在较低水平。
Nitrifying performance of moving bed A2/O process was observed under the condition of four days sludge age in this pilot scale experiment. The results illustrated that the process has a perfect nitrifying performance under the condition of high water temperature, and effluent NH3 - N concentration is below 8 mg/L. It is also found that the new process can achieve a low effluent NH3 ?N concentration under a high surface load of ammonia if optimized the position and fill proportion of suspended carriers into the aerobic tank.
