In china, the eutrophication induced by the nitrition pollution is haming the agriculture, fishing, tourism, and so on. it is also threaten the safe of drinking water and the foods. nitrition pollute the waterwhen it act in the way of NH4+, NO2-, N03- , et al. there are many methords to control the nitrition pollution, among which the most economical and good to enviroment way is bio-denitrogenation. the traditional bio-denitrogenation is built up of aerobic nitrification and anaerobic denitrification, the nitrifier are as follow: ammonia -oxidizing bacteria and nitrosomonas, ammonia-oxidizing bacteria includes Nitrosomonas, Nitrosoccus, Nitrosospira and Nitrosolobus et al. ;nitrosomonas includes Nitrococcus, Nitrobacter, et al. and the dinitrifier have some of the archaebacteria, Proteobacter and Bacillus, Corynebacterium, Prankia Nocardia of the Proteobacter, et al.The new aerobic nitrification-denitrification has become the new reseach and developing aim in the field of the bio-nitrification, because of the small outlay for construction, low cost devotion and easy to control et al.. at present,the reported aerobic nitrification -denitrification bacteria are as follow: Alcaligenes faecalis, Thiosphaera pantotropha (now, it is re-named as Paracoccus deni...
