Study on the recycling technology of waste catalysts and environmental problems

using the method of theory and experiment to study the generation of dioxin and the characteristic of leaching slag by using waste catalyst recovery

for putting forward the control methods and suggestions of the future environmental management of this kind of projects. The results of the study show that

the recycling technology of waste catalysts is more mature

pollutants can be effectively controlled; the production and emission of dioxin in the process of roasting can through the material management or environmental protect control; the content of heavy metals in leaching slag above 10-4

suggestions according to the hazardous waste management

on the other hand

according to the general solid waste management.
