| Abstract: | The reason for using waste sulfuric acid to adjust diammonium phosphate （DAP） product total nutrient and the measures of technological transformation are presented. After the renovation, the quality of DAP product is stable, the fluctuation of mass fraction of total nutrient is only ±0.3%, attaining the aim of same effect of using raw sulfuric acid to adjust product quality, saving raw sulfuric acid 1 700 t （pure acid） annually. |
