Simultaneous partial nitrification, anammox and denitrification (SNAD) process for treating anaerobic digester liquor of swine wastewater (ADLSW) was achieved successfully in a continuous‐flow biofilm reactor by gradually increasing the influent ammonium (NH4+‐N) concentration whilst controlling the low dissolved oxygen (DO) concentration. After 180 days of operation, the average removal efficiencies of NH4+‐N, total nitrogen (TN) and COD were 61.59%, 55.76%, and 75.21% respectively. Also, the average conversion efficiency () of total effluent nitrite and nitrate production to ammonia consumption was kept at about 0.053 at the last stage (days 181‐218). Anaerolineaceae (26.92%), Candidatus Brocadia (3.96%), Candidatus‐Kuenenia (4.69%), Armatimonadetes‐norank (4.25%), Limnobacter（4.15%）, Xanthomonadaceae (3.07%) and Ignavibacterium (2.87%) were the dominant genera in the SNAD system for treating ADLSW. The quantitative polymerase chain reaction (qPCR) results further confirmed that the co‐existence and enrichment of anammox bacteria, ammonium oxidizing bacteria (AOB), and denitrifying bacteria (HB) in the bioreactor.
