<p><P>PROBLEM TO BE SOLVED: To optimize a biological treatment process which easily and efficiently makes an organic solid soluble and decomposes it into a low molecule in a short time by utilizing a reaction characteristic of an anaerobiotic microorganism, to a hydrogen-methane two-stage fermentation treatment process of garbage-based organic waste. <P>SOLUTION: In this anaerobiotic treatment process and its device, in garbage-based organic waste treatment in which sugar-based waste is a main component or in garbage-based organic waste treatment including a cellulose solid, hydrogen and methane are biologically recovered which are returned to a process in which complete-mixture type solubilization and hydrogen fermentation for treating a raw material which is refined and homogenized in a preceding process and whose density is VS 5 to 15 wt.% by a biological reaction at 30 to 70°C, pH 5 to 8.5 and at a hydraulic retention time of 2 to 3 days in a font stage are combinedly performed, and a process in which a two-stage fermentation method composed of a complete-mixture type methane fermentation process at a succeeding rear stage is performed, and the anaerobiotic solubilization and hydrogen fermentation for solubilizing and fermenting a part of a flow-out component from a methane fermentation process are combinedly performed. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
