Sustainable Mining and Metallurgy

According to the characteristics of low ambient temperature in cold regions, domestic waste is easy to freeze into clusters, and calorific value is low, this paper discussed the measures of heating waste with hot waste water and hot leachate, increasing the ambient temperature above the waste pond, expanding the pond capacity, and adding waste crushing pretreatment system and wet hydrolysis pretreatment system. The implementation of these measures can promote the fermentation of domestic waste, reduce the moisture content, improve the calorific value, and help the combustion of waste furnace and the emission of offgas in winter.
