| 摘 要： | 氧化沟作为一种经济而有效的污水处理技术已被广泛应用，然而，传统的氧化沟工艺对氮和磷的去除效率较低。在该研究中通过调节曝气转刷的充氧能力，使氧化沟内形成好氧和缺氧段，总氮去除率越过９０％。为了提高氧化沟的除磷效率，在氧化沟系统内加入厌氧池，使总磷去除提高了２０％左右。试验结果表明，采用氧化沟工艺从城市污水中去除氮和磷是可行的。

| Abstract: | An oxidation ditch has extensively been used in many countries as an economic and efficient wastewater treatment technique.However,removal efficiencies of nitrogen and phosphorus in conventional oxidation ditches are low.Aerobic zone and anoxic zone can be formed in the ditch through controlling oxygen supply of the brush and TN removal is over 90%.In order toincrease removal efficiency of phosphorus,two anaerobic tanks were added in the oxidation ditch system,which increased about 20% of phosphorus removal.The experimental results show that removal of nitrogen and phosphorus from domestic wastewater by the oxidation ditch is feasible. |
