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.

Key words: hospital sewage, anaerobic process, aerobic process

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。
