Abstract

The invention discloses a process for treating phosphogypsum washing wastewater by using geological solid waste and an implementation system thereof, and relates to the technical field of natural stone treatment and waste recycling. Through synchronous treatment of geological solid waste and ardealite washing wastewater, collaborative consumption of the two types of waste is realized, and the problem of separation of solid waste stockpiling and wastewater treatment is remarkably reduced. Under the synergistic effect of alkaline excitation and the composite precipitator, the removal rate of phosphate, fluoride and heavy metal in the wastewater is remarkably increased, and the risk of secondary pollution is reduced.
