Nitrogen removal performance and microbial community of a simultaneous partial denitrification, anammox and denitrification system
In this study a novel simultaneous partial denitrification,anammox and denitrification system was achieved with the addition of glucose.The optimal nitrogen removal could be achieved when the influent glucose concentration was 56.4 mg L-1.The anammox activity was deteriorated with increasing glucose concentration.When the influent glucose concentration was increased to 374.9 mg L-1,the average ammonium removal efficiency decreased from 97% to around 10% and anammox activity was seriously inhibited.The anammox activity quickly recovered with decreasing influent glucose and increasing influent nitrite.High-throughput sequencing analysis suggested that the predominant genus changed from Candidatus Kuenenia to Diaphorobacter with the addition of glucose and then changed to Hydrogenophaga with the decrease of glucose.It indicated that organics concentration had an effect on the microbial communities.
