Based on the fact that the surface of waste low-temperature denitration catalysts is covered with ammonium bisulfate,which seriously affects the activity of the denitration catalyst,and during the process of recycled washing,ammonium bisulfate affects the physical strength of the waste denitration catalyst,therefore,this paper studied the high temperature calcination process before washing,which can remove some ammonium bisulfate from the waste low-temperature denitration catalyst to ensure the smooth completion of the regeneration of the waste low-temperature denitration catalyst.
