Research progress of wastewater treatment in metallurgical industry
China's steel production has exceeded 50%of the world's total production.As the main solid waste in the steel industry,steel slag has an annual output of 153 million tons in 2022 alone.Currently,the comprehensive utilization rate of steel slag is less than 30%,far lower than the utilization level of developed countries,and it is urgent to effectively treat and dispose of it.At present,there are many introductions on the utilization of steel slag,lacking a comprehensive and systematic introduction to the characteristics of steel slag.In view of this,this article provides a detailed introduction to the physicochemical characteristics of steel slag,the main treatment methods of steel slag,and the resource utilization methods of steel slag,providing a more comprehensive and reference for steel slag treatment in China.
