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,
