摘要：A method and system of treating wastewater is disclosed. The treatmentsystem has a nitrification-denitrification system comprising a sorption system, a biofilmsystem, and an anaerobic digester that digests or converts at least a portion of the solidsor sludge from the sorption system and biofilm system. The method can compriseproviding a wastewater to be treated and denitrifying the wastewater in a first biologicalreactor to produce a denitrified mixed liquor, nitrifying the denitrified mixed liquor with anitrifying biofilm on a earner and biosorbing undesirable constituents from the denitrifiedmixed liquor with a suspended biomass in a second biological reactor, and separating afirst portion of the nitrified mixed liquor in a separator to produce a solids-rich sludgeand a treated effluent having a total nitrogen concentration of less than about 10milligrams of elemental nitrogen per liter.
