Coking desulfurization waste solution treatment process and device

The invention discloses a coking desulfurization waste solution treatment process and device, relating to the technical field of desulfurization waste solution treatment. The coking desulfurization waste solution treatment process comprises the steps that a desulfurization waste solution is subjected to catalytic oxidation by a catalyst in an oxidation pot, and then is transferred to a centrifugal machine for removing elemental sulfur generated in an oxidation process, a flocculant is added into a filtrate under the condition of stirring, meanwhile the PH value of oxidation liquid is adjusted, then settlement is performed for 24 hours, so that Fe (OH)2 colloid produced by the reaction of the elemental sulfur and Fe in the oxidation liquid and OH in a solution is fully flocculated, supernatant passes through a membrane filtering device so as to remove the flocculated elemental sulfur and Fe(OH)2 colloidal impurities, then filtered liquid is subjected to activated charcoal decoloration in a decolouring kettle, and is put into a filtering machine for treatment, the liquid enters into an evaporation kettle and a crystallization kettle and is subjected to evaporative crystallization, and ammonium sulfate and ammonium thiocyanate products with high purity are produced. The coking desulfurization waste solution treatment process is low in production cost, easy to operate, energy conservation and stable operation are realized, and meanwhile the purity of the products are remarkably improved.
