Process system for separating and recovering sodium sulfate and sodium bromide from wastewater

The utility model belongs to the field of water treatment, and particularly relates to a process system for separating and recovering sodium sulfate and sodium bromide from wastewater. The process system provided by the utility model comprises an oxidation decoloration reactor, a cooling crystallization kettle, a first filter, a washing kettle, a second filter, a first evaporation kettle, a third filter, a dissolving kettle, a fourth filter and a second evaporation kettle. The process system provided by the utility model firstly adopts ozone/hydrogen peroxide to synergistically oxidize (free radical oxidize) organic matters in the wastewater; and separating and refining the sodium sulfate and the sodium bromide in the wastewater by means of cooling, dissolving, washing, evaporating and the like according to the solubility difference of the sodium sulfate and the sodium bromide in water to obtain high-purity sodium sulfate and sodium bromide products. The process system is small in danger coefficient, high in
