► We use primary sludge as the carbon source to enhance nitrogen removal of reject water in a novel system. ► Good nitrogen removal could be accomplished with the co-occurrence of sludge fermentation and denitrification. ► The degradation of primary sludge was accelerated by the existence of nitrate...
