Sustainable Mining and Metallurgy

In order to find out the technical development status and future technical development trend of hazardous waste in China, this paper combed and compared the characteristics and application scope of various hazardous waste pretreatment and harmless treatment technologies at home and abroad, and analyzed the methods and technical status of various hazardous waste resource utilization. According to the classification of metallurgical hazardous waste, petrochemical and chemical hazardous waste, medical hazardous waste, recycling of renewable resources, and collaborative treatment of various hazardous wastes, the current mainstream technologies, advanced technologies and future technologies were summarized. The analysis results show that incineration is the main treatment methods of hazardous waste in China, and rotary kiln incineration technology is widely used. There is still a certain gap between China and developed countries in the technical level of hazardous waste resource utilization. In the future, harmless, resource-based, collaborative and intelligent treatment technologies will be the main direction of technological innovation or optimization of hazardous waste treatment.
