铁碳电池预处理—厌氧—好氧—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 NH+ 4及有机物发生反应实现共同降解 ,亚硝酸盐与 NH+ 4 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 60 0 m g/ L 时 ,却除率大于 95 %。该方法成本低 ,处理效果较好
Iron-carbon battery pretreatment - anaerobic - aerobic - aerobic - anaerobic - multi-stage SBR coking wastewater treatment has made good COD, ammonia nitrogen removal effect. The creation of conditions in the SBR reactor not only ensures the smooth nitrification reaction but also ensures that the formed nitrite reacts with NH + 4 and organic compounds to achieve common degradation. The reaction between nitrite and NH 4 + The lack of carbon source during nitrification. System operation is stable, ammonia nitrogen concentration greater than 60 0 g / L, but the removal rate greater than 95%. The method has the advantages of low cost and good treatment effect
