摘要
在实际工程应用中,采用AO+MBR工艺可将电解锰生产废水中的氨氮浓度处理至≤10mg/L,前置AO生化工艺保证了氨氮及总氮的去除效果,后置MBR工艺可保证低碳源情况下系统的污泥浓度,使世代周期长的硝化菌能在好氧池内富集,保证了系统良好的硝化反硝化效果。
In practical engineering applications,the AO+MBR process can be used to treat the wastewater from electrolytic manganese production,and the ammonia nitrogen concentration in the treated wastewater can be reduced to the nitrogen concentration of≤10mg/L.The pre-AO biochemical process can ensure the ammonia nitrogen and total nitrogen removal effects,and the post-MBR process can ensure the sludge concentration of wastewater within the system under the condition of low-carbon source,so that the nitrifying bacteria with a long generation cycle can be enriched in the aerobic tank,and good simultaneous nitrification and denitrification effects within the system can be ensured.
