NOVELTY - A waste material is separated into fermentation appropriate material suitable for methane fermentation, and unsuitable material for methane fermentation. The fermentation unsuitable material and fermentation suitable material are fermented in dry-type methane-fermentation tank and putting side by side through furnace such as incinerator, gasified melting furnace, direct melting furnace and carbonization furnace. The residue produced in fermentation tank is spin-dehydrated in dehydrator which is provided in the downstream of dry-type-methane fermentation tank.    USE - Refuse treatment process of industrial waste using methane gas.    ADVANTAGE - The refuse treatment process of industrial waste material is efficiently and economically carried out using simple methane-type fermentation process.    DETAILED DESCRIPTION - A waste material is separated into fermentation appropriate material suitable for methane fermentation, and unsuitable material for methane fermentation. The fermentation unsuitable material and fermentation suitable material are fermented in dry-type methane-fermentation tank and passed by passing through furnace such as incinerator, gasified melting furnace, direct melting furnace and carbonization furnace. The residue produced in dry-type-methane fermentation tank is spin-dehydrated in dehydrator which is provided in the downstream of dry-type-methane fermentation tank. The dewatered sludge which is residue of spin-dehydrated is processed in fermentation unsuitable material processing furnace. After spin-dehydration, a portion of filtrate is mixed with fermentation appropriate material in mixer which is provided in the upstream of dry-type-methane fermentation tank, and then injected into the dry-type-methane fermentation tank. The remaining portion of filtrate is sprayed and burned in the secondary combustion portion of fermentation unsuitable material processing furnace. Thus, the refuse treatment process is enabled. The fermentation appropriate material comprises a mixture of mixed papers with organic refuse.
