| 摘 要： | 青岛李村河污水处理厂采用改良A／O工艺，具有脱氮及部分除磷功能。通过调节使其按倒置A^2／O模式运行，并开展了脱氮除磷的生产性试验，考察了溶解氧浓度、污泥回流比、温度等对除污效果的影响。结果表明，倒置A^2／O工艺对有机物、氮、磷的去除效果好，且运行稳定、抗冲击负荷能力强，适合在我国城市污水处理领域推广。

| Abstract: | Reversed A^2/O process was studied using the existing equipments in Qingdao Licunhe Sewage Treatment Plant. Influences of dissolved oxygen concentration, sludge reflux ratio and temperature on pollutant removal were investigated. The productive test results show that the reversed A^2/O process is excellent in removing organics, nitrogen and phosphorus. Furthermore, the process has the advantages of steady operation and strong ability to withstand shock loads. It can be used in many new-built wastewater treatment plants in China. |
