| Zusammenfassung: | The invention discloses a method for recycling and treating calcium ammonium nitrate and ammonium nitrate condensed wastewater, and belongs to the technical field of industrial wastewater treatment.The method comprises the steps that ammonium nitrate wastewater condensate and evaporation condensate are mixed and input into a neutralizing tank, calcium ammonium nitrate process condensate is conveyed into a storage tank B and pumped into an intelligent ionization descaling device through a storage tank lifting pump, and the ammonium nitrate wastewater condensate and the evaporation condensate are recycled; after most of Ca < 2 + > in water is removed, the wastewater enters a sodium ion exchanger to further remove Ca < 2 + > in water, and then the wastewater enters a neutralization tank to be subjected to PH adjustment together with ammonium nitrate wastewater; pumping into a storage tank A through a neutralization lift pump; pumping the ammonium nitrate and calcium ammonium nitrate mixed liquor wastewater subje |
