<P>PROBLEM TO BE SOLVED: To provide a treatment method for recycling of nonindustrial waste contaminant and to provide its apparatus. <P>SOLUTION: The treatment method of contaminant consists of a pretreatment and a charring carbonization which are carried out in a construction having a whole system connected with duct and a closed structure with a few contacts the air outside. In the pretreatment step, a nonindustrial waste contaminant is dehydrated and pulverized, aluminum and iron components are removed with a magnetic separator, then a catalyst (wherein an active carbon and MgO are dried and mixed) is thrown in and agitated with a stirrer in a drying chamber, and thereafter another pulverization, removal of iron with the magnetic separator and drying are carried out. And in the charring carbonization step, the pretreated material is thrown in a carbonization oven to be carbonized and the carbonized material is cooled to give a product. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
