<p>A method for processing waste containing a large amount of water and a method for processing leachate from industrial wastes. A waste processing method comprises maintaining reduced pressure in a dryer (1) equipped with a stirring means (3) feeding waste containing a large amount of water to the dryer, stirring the waste while blowing refrigerated air at - 20 DEG C +/- 5 DEG C to the dryer, and drying the frozen moisture portion of the wastes by sublimation. Air heated at 80 DEG C +/- 10 DEG C can be used instead of refrigerated air to dry water of the wastes by evaporation. A method for processing leachate comprises pooling leachate industrial wastes and burned ashes, and utilizing the leachate to absorb wet-type toxic gas, thereby confining the leachate within the waste treatment plant. This makes it possible to process waste containing a large amount of water, which has been a problem in incineration by conventional methods, by using the potential heat of the waste gas from the incinerator to refrigerate or heat the air for the dryer and to prevent environmental contamination because leachate is confined in the waste treatment plant. <IMAGE></p> |
