China is a large country of phosphogypsum resources, and the phosphogypsum becomes the second large industrial solid waste after fly ash in China. Because the production amount of the phosphogypsum is large and relatively centralized, and simultaneously, the phosphogypsum contains certain impurities and is difficult to be innoxiously treated, the global phosphogypsum comprehensive utilization rate is only about 20 percent at present. In 2018, the production of phosphogypsum in China is 7800 million tons, which is increased by 4 percent on a same scale, and hundreds of millions of tons of stacked phosphogypsum need to be digested at the present stage, so that the resource utilization of the phosphogypsum is urgent.
More than 80% of the phosphogypsum production emission of China is concentrated in Hubei, Yunnan, Guizhou, Anhui and Sichuan provinces, and the method has the typical regional characteristics, the spatial distribution of phosphorite causes uneven distribution of phosphogypsum production space, the additional value of downstream products is low, and the utilization difficulty is high. Secondly, annual discharge and annual stockpiling of phosphogypsum have restricted the sustainable development of the phosphorus chemical industry. At present, most of phosphorus fertilizer production enterprises in China can only heap up the solid waste phosphogypsum, so that not only is a large amount of land occupied, but also a large amount of capital is invested to carry out anti-seepage treatment on the piled-up phosphorus gypsum, and economic burden is brought to the development of the enterprises.
The phosphogypsum contains a large amount of phosphorus, fluorine, various salts and heavy metals, and the ecological environment such as atmosphere, soil, underground water and the like in a piled land and a nearby area is seriously harmed by improper treatment. Therefore, the promotion of resource utilization of the phosphogypsum has important significance in terms of society, environment and economy.
