Sustainable Mining and Metallurgy

In view of the complexity of the current source of hazardous waste in a hazardous waste disposal center, this paper quantitatively analyzed the moisture, ash, calorific value and heavy metal content of 38 typical organic hazardous wastes. The results show that the water content of the hazardous waste treated in this paper is 30.62%, the ash content is 27.40%, and the low calorific value is 2497kcal/kg. It is a typical organic hazardous waste with low calorific value, high water content and rich in heavy metal elements such as Zn, Cu, Cr and Ni. At the same time, this paper introduced the principle of countercurrent incineration technology, compared and analyzed the technical characteristics of countercurrent and downstream, summarized the advantages and technical difficulties of countercurrent incineration technology, and introduced the incineration operation, flue gas purification process and economic indicators of countercurrent incineration technology through the incineration production practice of organic hazardous waste with low calorific value and high water content. Countercurrent incineration technology can achieve lower slag ignition loss rate, dioxin and incineration flue gas emissions. It is an advanced incineration technology, which broadens the scope of feeding, realizes the efficient disposal of organic hazardous waste with low calorific value and high water content, and helps to reduce the cost of enterprises.
