摘  要:
The three treatment methods of phosphorus wastewater in phosphate fertilizer production areintroduced. The phosphorus in wastewater is not used by using the lime neutralization method. Usingwastewater instead of slurry water for production of phosphoric acid and using wastewater to produce feedgrade dicalcium phosphate can recycle P2O5in wastewater, at the same time the water is cycled utilization.
