| 摘 要： | 铁碳电池预处理－厌氧－好氧－缺氧多级SBR法处理焦化废水取得了良好的COD、氨氮脱除效果。在SBR反应器中创造条件，既保证了亚硝化反应的顺利进行，同时又保证了生成的亚硝酸盐与NH4^＋及有机物发生反应实现共同降解，亚硝酸盐与NH4^ 的反应弥补了反亚硝化过程中碳源的不足。系统运行稳定，氨氮浓度大于600mg/L时，却除率大于95％。该方法成本低，处理效果较好。

| Abstract: | The coke oven waste water can be treated by multi-stage SBR process with high removal rate of NH 3-N and COD. The conditions are provided in the SBR to ensure that nitrification/denitrification via nitrite and ammonia oxidation can be simultaneously carried out. The reaction of ammonia and nitrite can make up for carbon shortage in the process of denitrification. The removal rate of NH 3-N is over 95 % in the total system even if the concentration of NH 3-N is over 600 mg/L at low cost. |
