Current situation of comprehensive utilization technology of solid waste of phosphorus chemical

China's phosphorus chemical industry is a pillar industry in the development of national economy, but in the process of phosphorous chemical industry, a large number of industrial solid wastes such as phosphorous tailings, phosphogypsum and phosphorous slag have been produced, and the accumulation and consumption of solid wastes have restricted the healthy development of China's economy.How to deal with and use this part of resources is of great significance to the sustainable and healthy development of the whole industry.In order to further understand the status of the comprehensive utilization technology of solid waste of phosphorus chemical industry in China, this paper introduces the output, physical and chemical properties, stockpiling hazards and treatment status of solid wastes in detail.The comprehensive utilization technology status of three typical solid wastes of phosphorous chemical industry, such as phosphorous tailings, phosphogypsum and phosphorous slag in industry, agriculture, cement, construction and other aspects is described.Then, the existing problems of solid waste in phosphorus chemical industry in China, such as low comprehensive utilization rate, product transformation in the primary stage, and not realizing full resource recycling are summarized.Finally, in view of the future development route of solid waste treatment, reasonable suggestions are put forward from the aspect of technical feasibility.It is expected that the status of large amount of solid waste accumulation in phosphorus chemical industry in China can be effectively improved and the comprehensive utilization technology can make breakthroughs.
