Abstract

Abstract

Vanadium production generates significant quantities of “triple-high” complex vanadium-extracted wastewater (high in ammonia-nitrogen, hexavalent chromium, and salt) from sodic roasting vanadium extraction, alongside magnesium-rich desulfurization effluent from flue gas desulfurization. These effluents pose significant resource and environmental challenges. Traditional separate treatment methods for these wastewater face challenges of large land occupation and high maintenance costs. This study proposes a struvite-driven co-treatment strategy aimed at the preliminary treatment process, where vanadium-extracted wastewater serves as the nitrogen source and desulfurization wastewater provides magnesium for struvite precipitation. Under optimal conditions (pH = 9.5, n(Mg):n(N) = 1.8, n(P):n(N) = 1.5, reaction time = 15 min) with in-progress precipitation pH adjustment mode. The process enabled recovery of NH₄⁺–N (97.72%) and Mg²⁺ (86.62%), and precipitated Cr-free struvite (73.24%) and hazenite (23.75%), highlighting its dual-resource recycling capability. Additionally, the process reduced chemical usage by 22%-60% and minimized land occupation, thereby reducing the treatment load of subsequent high-salt wastewater. This research provides a new and efficient strategy for the resource utilization of wastewater generated by vanadium plants.
