摘　　要：由于A2/O工艺中存在反硝化菌与聚磷菌竞争碳源、异养菌与自养菌泥龄矛盾、回流硝酸盐对聚磷菌释磷的影响等问题,造成了工艺对N、P同时去除效果不佳,针对这些问题分别提出了几种解决措施和改良工艺。克服了A2/O工艺部分固有缺陷,优化和提高了其处理能力。Because there are some problems,just like the denitrification fungus with to gather the phosphorus fungus competition carbon source,the heterotrophic bacteria and the autotrophic bacterium putty age contradiction,the backflow nitrate to gathers the phosphorus fungus to release phosphorus and so on,in A^2/O process,which caused the craft to N,P simultaneously to remove the effect not to be good.Researchers proposed several kinds of solution measures and the improvement craft separately in view of these questions,which has overcome A^2/O craft part inherent flaw and optimized and sharpened its handling ability.

关 键 词：A2/O工艺 脱氮除磷 碳源 泥龄 硝酸盐 工艺改良
