| 摘 要： | 根据兰州某石化污水处理装置生产的实际案例验证了低浓度甲醛在活性污泥法处理废水时对氨氮的影响.工艺运行数据表明,在甲醛浓度超过5mg/L、持续时间超过8h时,虽然对废水中COD的处理未见影响,但是对氨氮去除率影响显著.

| Abstract: | The effect of low concentration formaldehyde on treatment of ammonia nitrogen wastewater by the activated sludge process was verified. The process operation data show that, when the concentration of formaldehyde exceeded 5 mg/L and the duration was more than 8 hours, no impact on the treatment of COD in wastewater was obviously identified, but the removal rate of ammonia nitrogen was significantly affected. |
