Completely Autotrophic Nitrogen-Removal for Treatment of High Ammonia Leachate

摘要：

This study focused on the feasibility of autotrophic nitrogen removal to treat high ammonia leachate,using combined partial Nitritation and Anammox process.In partial nitritation reactor,the optimal operation condition was found with influent ammonium concentration of 1200 mg/L,DO about 3 mg/L,HRT 3 days and temperature about 31℃ at the ratio of NO2-N / NH4-N effluent kept at 1.1,which is a prerequisite for the application of Anammox.In Anammox reactor,more than 85％ ammonium is removed at HRT 8 days,temperature 28±1 ℃,and pH 8.The removal rate of nitrogen and COD in combined partial Nitritation and Anammox process are 90％ and 74％,respectively.Thus,a combined process of partial nitritation and a subsequent Anammox could be an alternative solution for ammonium removal for leachate.
