Abstract:To improve the treatment performance of anaerobic ammonium oxidation (ANAMMOX) processes at low temperatures, the immobilized cold‐acclimation ANAMMOX granules (R3) were prepared and their low‐temperature nitrogen removal ability as well as the cold adaptation mechanism were analyzed. The results indicated that the total inorganic nitrogen (TIN) removal efficiency of R3 was significantly higher than that of R2 (cold‐acclimation granules without immobilization) and R1 (common granules), especially at 11 ± 2 and… Show more
