Study on the Removal of High-concentration Chloride Ion from Desulfurization Wastewater in Thermal Power Plant by Removing Chlorine Extractant

Abstract

In this study, a dechlorination extractant was used to study the removal rate of high concentration chloride ion in desulfurization wastewater from thermal power plant. The test determined the optimal extraction process parameters of the chlorine removal agent by comparing the extraction of the chlorine extractant, the extraction time, the time of the static phase separation, and the method of dosing. The experiments of back-extraction time and static phase separation time were carried out to determine the optimal back-extraction process parameters of the chlorine removal agent. At the same time, the feasibility of applying the chlorine extraction agent to the cycle was verified.
