Introduction Wengfu phosphate fertilizer plant in recent years, the implementation of energy saving, “three wastes” use of technological transformation projects. Production operation shows that: the heat and steam output has reached the designed value, the coal consumption has been reduced by 7.66%; the power consumption per ton of sulfuric acid has been reduced by 70 kW.h; the dry cost per ton of DAP decreased from 32.76 yuan to 2.55 yuan and the acid consumption decreased by 5.88 %, Ammonia consumption decreased by 2.61%. The energy-saving devices, “three wastes” use of remarkable results, the whole plant wastewater utilization rate reached 70%.
