The contrast study of anammox-denitrifying system in two non-woven fixed-bed bioreactors (NFBR) treating different low C/N ratio sewage

► Study the performance of two NFBRs under different substrates, respectively. ► Study the adaptabilities of anammox-denitrifying system for organic matter. ► Study the adaptabilities of anammox-denitrifying system for temperature. ► Determine nitrogen removal approaches of anammox-denitrifying systems.
