Abstract
Aiming at the difficulty in treating electroplating chromium-containing wastewater and the high cost of conventional reducing agents(sodium metabisulfite),a method using sodium sulfite derived from wet flue gas desulfurization by-products as an alternative reducing agent is proposed.Through systematic analysis of its chemical properties,reaction conditions,and economic performance,the applicability for treating chromium-containing wastewater was evaluated.The results indicate that under conditions with pH ranging from 1 to 3,the by-product sodium sulfite can effectively reduce hexavalent chromium to trivalent chromium.When the oxidation-reduction potential is controlled at 300 mV,the effluent hexavalent chromium concentration is below 0.05 mg/L,and total chromium is below 0.5 mg/L.Although the treatment efficiency is slightly lower than that of sodium metabisulfite,the consumption of liquid alkali can be significantly reduced.The overall treatment cost is reduced by 15%compared with the conventional process.This approach realizes the reuse of waste resources and provides a feasible pathway for chromium-containing wastewater treatment and resource utilization of desulfurization by-products.关键词
