【摘要】采用厌氧与交替缺氧和好氧技术相结合的A2/O工艺处理医院综合污水,取得了很好的效果。该工艺与传统的活性污泥法A2/O工艺相比有更多的优点,总氮去除率86.1%,NH3-N去除率92.9%,磷去除率82.2%,节能16.6%,处理后的综合污水各项指标均达到了医院现行排放标准的要求。更多还原

【Abstract】 A combined A2/O technology using anaerobic with alternative anoxic and aerobic processes has been used to treat hospital complex sewage.All the indexes have achieved very good results.Comparied with traditional activated sludge method,A2/O technology has more advantages.The total denitrification rate can be up to 86.1%,the removal rate of NH3-N is 92.9%,and the dephosphorization rate is 82.2%.And,16.6% of energy can be saved.Every index of the treated complex sewage meets the current discharge standard.更多还原
