This article analyzes resource utilization of desulfurization dross, suggesting its potential in building materials and agriculture.
As a solid waste generated during the desulfurization process of coal-fired power plants, the output of desulfurization dross is increasing year by year. If not properly treated, it may occupy land and potentially pollute the environment. The article summarizes and analyzes the physical and chemical properties of desulfurization dross, as well as the progress in resource utilization of semi dry desulfurization dross. The application potential of semi dry flue gas desulfurization dross in building materials, agriculture, wet flue gas desulfurization, sludge and wastewater treatment, and high value-added fields was discussed in detail, achieving comprehensive utilization of resources, reducing environmental pollution, and increasing considerable economic benefits for related enterprises. The article points out that in the future, it is necessary to optimize the stability pretreatment technology of desulfurization dross and strengthen its environmental risk control to achieve large-scale and high-value applications. The article also looks forward to the research direction of semi dry calcium based desulfurization dross in the future, aiming to provide reference for the sustainable development and environmental protection of semi dry desulfurization dross.
