Postdenitrification Biofilters Can Be Optimized For Bioavailable Dissolved Organic Nitrogen Removal In Wastewater

The outlet water quality of many municipal wastewater treatment plants (MWWTPs) is characterized by high nitrogen strength, which can cause culture eutrophication. Due to the more and more stringent effluent total nitrogen discharge standards in China, MWWTPs need to upgrade and reconstruct. Postdenitrification biofilters (DNFs) have been used for tertiary nitrogen removal in MWWTPs because of their high efficiency and low cost. In this process, oxidized nitrogen is denitrified to nitrogen gas under anoxic conditions, with organic carbon as the...
