Abstract:
1. A method of treating organic matter, said method comprising the steps of thermal decomposition of material organic matter and treating gas generated in said thermal decomposition step, characterized in that: said step of thermal decomposition comprises the step of decomposing said material organic matter into carbide and gaseous component, and said gas treatment step comprises the steps of: (1) catalytically oxidizing the gaseous component generated in said thermal decomposition step; (2) neutralizing/washing the oxidized gas; (3) subjecting waste water produced in said neutralization/washing step to solid-liquid separation; (4) thermally decomposing a solid component again separated in said solid-liquid separation step together with said material organic matter in said thermal decomposition step; and (5) recycling the liquid component separated in said solid-liquid separation step to at least of one of said solid-liquid separation step and said neutralization/washing step, wherein said solid-liquid separation step comprises the steps of evaporating said waste water produced in said neutralization/washing step and filtering liquid produced in this evaporation step through a bag filter to separate the liquid into solid and liquid components.
