摘　　要：氨氮的硝化是污水脱氮处理的重要前提,因此强化硝化对生物脱氮和污水处理都具有重要的意义,近年来侧流富集/主流强化硝化工艺越来越受关注。介绍了污泥水富集硝化菌强化硝化工艺、回流污泥曝气再生强化硝化工艺和闭式双泥龄活性污泥工艺,论述了三种工艺的工艺流程、运行原理、工艺特点及工程应用,为今后污水处理厂的建设和升级改造提供借鉴。The nitrification of ammonia nitrogen is the important premise of sewage denitrification treatment.Therefore, the enhanced nitrification has the important meaning for the biological denitrification and sewage treatment. Om recent years, it is more and more to pay attention to the side stream enrichment / mainstream enhanced nitrification process. The article introduces the enhanced nitrification process of sludge water enriched nitrification bacteria, the return sludge aeration regeneration enhanced nitrification process and the closed double sludge age activated sludge process. The article discusses the technological flow, operation principle, technological characteristics and engineering application of three processes, which provide the reference for the construction, upgrading and reconstruction of wastewater treatment plants in the future.
