摘要
重点讨论了有效微生物群 (EM)对生活污水中氨氮的去除效果 .结果表明 :EM在好氧条件下能显著提高污水中氨氮 (NH+4 -N)的去除率 ,在EM投加比例 (VEM/V污水 )为 8‰时 ,去除率增幅达 13.31% ;中性偏碱的环境(pH值 =7～ 9)也是提高氨氮去除效果必不可少的条件之一 .在实际工程应用中 ,应根据不同的目的 ,选择合适的反应条件 .
The effect of effective microorganisms(EM) on the removal of ammonia and nitrogen in domestic sewage has been discussed. The result shows that:In aerobic condition, 8‰ of EM addition could enhance the NH\++\-4-N removal rate significantly with a largest increment of 13.31%. Alkaline environment (pH is 7～9) was also needed in enhancing the NH\++\-4-N removal rate. But suitable reaction conditions should be chosen according to different purposes.
