Document Type and Number:
WIPO Patent Application WO/2024/037041
Kind Code:
A1
Abstract:
A desulfurization wastewater treatment system and method. The desulfurization wastewater treatment system comprises a pretreatment device used for pretreating desulfurization wastewater, so as to remove divalent ions in the desulfurization wastewater; an electrolysis device used for electrolyzing the pretreated desulfurization wastewater; a gas-liquid separation device used for carrying out gas-liquid separation on a gas-liquid mixture generated in the electrolysis device; a dechlorination device used for dechlorinating hydrogen separated out in the gas-liquid separation device; a hydrogen pressurization device used for performing pressurization and cooling drying on the dechlorinated hydrogen; and a hydrogen deoxidation device used for deoxidizing the hydrogen subjected to the pressurization and cooling drying. The present invention treats desulfurization wastewater and can produce a sodium hypochlorite solution and hydrogen; the whole process does not generate and discharge waste.
