Research on Nitrogen Removal by ANAMMOX Biofilter Process in Different Concentrations

Abstract:

To study the concentration of anammox process in the biofilter .Making ANAMMOX biofilter as the reactor, control the reaction water temperature at 25~31°C,increasing the influent concention of NH4+-N and NO2--N gradually to study the rule of denitrification of ANAMMOX biological filter layers in different concentrations load variation. ANAMMOX biofilter filter layer biomass distribution after the frist increase and then decrease gradually, the last flatten the trend. The biomass of ANAMMOX is concentrated in the 0~50cm filter layer and inlet at low biomass.The denitrification performance of ANAMMOX best at the concentration of NH4+-N and NO2--N 90 mg/L,120mg/L, but will be greater inhibited at the concentration of NH4+-N and NO2--N higher than 120 mg/L,160mg/L.
