China is a major coal as energy, air pollution was smoke characteristics. Control coal pollution, particularly sulfur dioxide pollution, the most important way is FGD. Application of the current flue gas desulfurization equipment, with over 80% of wet FGD technology, with lime or limestone-gypsum wet desulfurization systems-based. Gypsum is lime or limestone-gypsum wet desulfurization process by-product, containing a variety of impurities, its compressive strength, tensile strength and so can not compete with natural gypsum, reuse of little value and has to be abandoned, use up a lot of land. Gypsum is a serious source of pollution hazards, the decomposition of gypsum powder by the wind into the formation of suspended particles in the air, the impact of animal health and plant growth, gypsum erosion by rainwater infiltration land farmland, pollution of surface water and groundwater, we enter the food chain. If we do not take positive and effective measures to release harmful substances will cause great human harm. This paper analyzes the gypsum to the basic characteristics and hazards, This paper introduces the gypsum emissions and application of cementitious materials and Comprehensive Utilization Research. Focused on the European and domestic gypsum to the comprehensive utilization of channels, technically, Application of the economy as well as the prospect of a detailed analysis to identify the domestic application of gypsum to the shortcomings and problems, proposed solutions and recommendations. Alternative part of the gypsum mine filled with cement as cementation material utilization to do a more detailed test, Verification of the program, the feasibility of a comprehensive utilization of gypsum ways summarized and discussed.
