    Abstract: The present invention provides a method for processing wastes containing a large amount of water and a method for processing leachate from industrial wastes. Specifically, the present invention provides a method which comprises maintaining reduced pressure in the dryer equipped with a stirring means, feeding wastes containing a large amount of water to the dryer, stirring the wastes while blowing refrigerated air at -20.degree. C..+-.5.degree. C. to the dryer, and drying the frozen moisture portion of the wastes by sublimation. Air heated at 80.degree. C.+10.degree. C. can be used instead of refrigerated air to dry water of the wastes by evaporation. The present invention also provides a method for processing leachate which 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. The present invention therefore make it possible to process wastes containing a large amount of water, which have been a problem in the incineration by the conventional methods, by using the potential heat of the waste gas from the incinerator. The present invention also provides an effective means to prevent environmental contamination because leachate is confined in the waste treatment plant.

    Abstract translation: 本发明提供一种处理含有大量水的废物的处理方法以及从工业废物处理渗滤液的方法。 具体地说,本发明提供了一种方法,该方法包括:在装有搅拌装置的干燥机中保持减压,将含有大量水的废物送入干燥器中,同时在-20℃冷却空气的同时搅拌废物。 5℃,并通过升华干燥废物的冷冻水分部分。 在80℃+ 10℃下加热的空气可以通过蒸发而代替冷冻空气对废物的干燥水。 本发明还提供了一种处理渗滤液的方法,其中包括将渗滤液工业废物和烧灰混合,利用渗滤液吸收湿式有毒气体,从而将渗滤液限制在废物处理厂内。 因此,通过使用来自焚烧炉的废气的潜热,本发明使得可以通过常规方法处理含有大量水的废物,这些废水是焚化问题。 本发明还提供了防止环境污染的有效手段,因为渗滤液被限制在废物处理设备中。
