Abstract:

At present, the accumulated amount of waste phosphogypsum in China has reached 3×10 8 tons, which causes waste of land resources and environmental damage.Using phosphogypsum in infilled wall system can not only achieve solid waste utilization, but also save energy, which is advantageous to economic development.During the “two sessions” in 2020, deputies to the National People's Congress proposed to comprehensively implement the “production based slag” policy.In order to speed up the ecological green and high-quality development process of phosphorus chemical industry in China, based on the research and development status of phosphogypsum at home and abroad, the advantages and disadvantages of phosphogypsum were summarized and the development potential of phosphogypsum infilled walls were explored.Combined with the actual application status of phosphogypsum infilled walls, the shortcomings of phosphogypsum used in infilled walls structure system were found.Finally, the research and application direction of phosphogypsum infilled walls were prospected, which could provide reference for assembly type phosphogypsum infilled walls and help the sustainable development of phosphorus chemical industry.

Key words: utilization of solid waste, production based slag, phosphogypsum infilled walls, assembly type
