| Abstract: | States denitrification theory and impacting factors of biological wastewater treatment,the basic process of ammonia translation of wastewater treatment is amination,assimilation,nitrification and denitrification,the main impacting factors of ammonia translation are temperature,pH,dissolved oxygen(DO),ratio of C/N,sludge age and noxious matters etc.Introduces several novel processes of biological denitrification,including preanoxic,postanoxic suspended and attached growth technologies.Sum up typical design criteria of different denitrification processes. |
