Disposal refers to the activities of burning solid waste and changing its physical, chemical and biological characteristics by other methods, so as to reduce the output of solid waste, reduce the volume of solid waste and reduce or eliminate its dangerous components, or finally put solid waste in a landfill that meets the requirements of environmental protection. Hazardous waste disposal mainly includes incineration disposal and landfill disposal.
Why do hazardous waste disposal need pretreatment?
Hazardous wastes are complex in composition and vary in size. In order to avoid the mixing of reactive waste, realize the homogenization and stabilization of feed and improve the efficiency of subsequent treatment, it is necessary to pretreat hazardous waste.
Before entering the furnace, the garbage should be mixed according to its composition, calorific value and other parameters. In the process of proportioning, we should pay attention to the compatibility between wastes, so as to avoid that large-size wastes can not be directly burned in the furnace after being mixed with incompatible wastes, but should be pulverized and burned in the furnace.
