Abstract:

Nitritation,which has plenty of advantages,is a newly developed method for biological denitrification inthe last few years. Its principle is introduced briefly,and implementation approach and maintaining methods including the control of DO concentration, temperature,pH,SRT,free ammonia,aeration time and so on are analyzed.Meanwhile,the advantages and disadvantages of these methods are also analyzed objectively. In addition,the research actualities of combination of nitritation and other technologies as well as application of modern molecular biology techniques to nitritation are described briefly. At the end,the practical application and prospect of nitritation are forecast.

Key words: nitritation, biological denitrification, molecular biology

摘要:

亚硝酸型硝化脱氮是近年来开发的一种新型生物脱氮技术,具有诸多优势。简要介绍了亚硝酸型硝化技术的原理,分析了亚硝酸型硝化的实现途径和维持方法,包括控制DO浓度、温度、pH、污泥龄、游离氨、曝气时间等,并客观分析了各种方法的优点与不足。对亚硝化与其他新型脱氮技术联用的研究现状、现代分子生物学技术在亚硝酸型硝化技术中的应用进行了简述,最后展望了亚硝酸硝化技术在实际工程中的应用实践以及发展前景。
