Solar energy PV/T desulphurization wastewater treatment system

The invention discloses a solar energy PV/T desulphurization wastewater treatment system which belongs to the technical field of solar energy heat utilization. The system includes a photovoltaic and photothermal power generation heat collecting system and a desulphurization wastewater treatment system. The system achieves integration coupling of each system through a flash-boiling evaporator; electric energy generated by photovoltaic and photothermal assemblies is supplied to a system and grid-connected generation through inverter power generation; a photovoltaic battery is cooled by low temperature charging sea water; and the photoelectric conversion efficiency of the photovoltaic and photothermal assemblies is improved. Steam generated by the flash-boiling evaporator is condensed into fresh water; the fresh water is sent to an absorption tower; sulfur in flue gas introduced is absorbed through a limestone-gypsum wet method; acid-base neutralization is performed on desulfurization wastewater generated from t
