Influence of landfill leachate on mixed ANAMMOX bacteria

The anaerobic ammonium oxidation(ANAMMOX)reactor in an upflow blanket filter(UBF).The authors spent 165 days in successfully transited starting up.The ANAMMOX was from the autotrophic denitrification.After the start-up of the ANAMMOX reactor,the volumetric loading rate was up to 0.17kg total nitrogen/(m3.d)with the removal rate of 93% for NH+4-N and 100% for NO2--N,respectively.On this basis,the effluent of nitrification of landfill leachate affecting the mixed ANAMMOX bacteria is investigated.The results indicate that the effluent of nitrification of landfill leachate produced a weak effect of ANAMMOX process.The ammonia and the nitrosation of average inhibition rate are 10.73% and 11.71%,respectively in the low concentration of ammonia of 60mg/L.
