Abstract：To address the high energy consumption and low eficiencyin current coal-to-hydrogen wastewater treatment，an integrated nitrogenremovalreactor wasconstructed，and itsdenitrification performanceand microbial community structure were investigated. The results showed that， under the conditions of gas-to-liquid volume ratio 80：1 ， temperature 33-35∘C ， and influent ammonia nitrogen volumetric loading rate 0.2kg（N）⋅m-3⋅d-1 ，rapid reactor start-up was achieved. Without external organic carbon sources， the effluent COD was below 60mg⋅L-1 ， ammonia nitrogen mass concentration was below 5mg⋅L-1 ，and total nitrogen removal rate was 93.6% . Nitrosomonas and Candidatus Brocadia were the dominant nitrogen-removing functional genera，short-cut denitrification process was helpful to improve the removal rate of total nitrogen.
