厌氧氨氧化脱氮技术在高氨氮废水中的应用

APPLICATION OF ANAMMOX DENITRIFICATION TECHNOLOGY IN TREATMENT OF WASTEWATER WITH HIGH CONTENT OF AMMONIA-NITROGEN

传统硝化反硝化工艺可以很好的处理高氨氮废水,但随着国内经济不断发展,同类型企业竞争不断加剧,企业利润被压缩,同时国家越来越重视环保,并于2014年4月24日出台新环保法,在国家和同类型企业双重压力下,传统硝化反硝化生物脱氮工艺的高能耗、运行成本高已成为企业负担。科技在进步,生物脱氮技术也在发展,厌氧氨氧化、短程硝化反硝化、同步硝化反硝化等新的脱氮技术也在不断涌现,重点分析了厌氧氨氧化技术发展过程、工艺原理以及在工程中的应用,为今后厌氧氨氧化脱氮技术发展提供了实践经验。

Traditional nitrification-denitrification technology can treat wastewater with high content of ammonia-nitrogen well.But this technology has become a burden for enterprises because of its high energy consumption and high operating costs.With the progress of science and technology,biological denitrification technology is developing as well.New denitrification technologies such as anaerobic ammonia oxidation,short-range nitrification and denitrification and simultaneous nitrification and denitrification are emerging constantly.This paper focuses on analyzing the technological development and principles of anaerobic ammonia oxidation process and the engineering application of this technology,which presents practical experience for the development of denitrification technology by anaerobic ammonia oxidation in the future.
