The invention discloses a method for reducing aqua ammonia energy consumption in a desulphurization process. According to the reason of high aqua ammonia consumption, corresponding consumption reducing treatment is performed. The reason of high aqua ammonia consumption includes great solution loss in the desulfurization process, too high speed increase of side reaction (NH4)2S2O3 and too high semi water gas temperature; the corresponding noise reduction treatment includes equipment inspection for reducing the running, emitting, dripping and leakage situations when the high aqua ammonia consumption is caused by the great solution loss in the desulfurization process; the corresponding noise reduction treatment also includes the operation of reducing desulfurizer input amount when the high aqua ammonia consumption is caused by the too high speed increase of the side reaction (NH4)2S2O3 in the desulfurization process; the corresponding noise reduction treatment also includes the operation of reducing the water ga
