Description of the Related Art Conventionally, livestock manure and the like have been treated under anaerobic conditions to generate biogas such as methane gas, which is used as fuel. In this case, methane fermentation generally occurs via acid fermentation, but such a biogas usually contains a large amount of hydrogen sulfide, which not only causes a bad smell of the biogas but also However, there is a disadvantage that the facility using the gas is corroded. In addition, there is a drawback that an odor during storage of manure or the like before the anaerobic treatment also destroys the environment.

利用することが容易となる。[0007] The activated carbon used in the present invention is not particularly limited, but it is particularly preferable to use rice husk charcoal from the viewpoint of low cost and good handling. If this activated carbon is added to the storage tank together with the organic waste, it is possible to prevent the generation of offensive odor which has conventionally been generated from the organic waste storage tank. Also, by mixing organic waste in an anaerobic fermenter, the sulfur content in the generated biogas can be significantly reduced. Therefore, in the present invention, activated carbon is previously added to an organic waste storage tank, and the organic waste containing the activated carbon is quantitatively transferred to an anaerobic fermenter and treated under anaerobic conditions. Is preferred. By doing so, a biogas having a low sulfur content can be constantly generated, so that it is easy to recover the biogas and use it as a clean energy source.

公知の方法によって適宜撹拌・混合すれば良い。In the present invention, the amount of activated carbon added may be any amount that produces the above-mentioned effects. However, since there is no advantage by increasing the amount more than necessary, usually, the volume% in the mixture is
It is sufficient to add an amount of 2 to 10%. The above effect by adding activated carbon can be simply assumed to be a preferential adsorption effect of sulfur by activated carbon. However, as the amount of activated carbon added increases, the amount of biogas recovered also seems to increase, so the activated carbon has a porous structure, which may act as a bacterial bed, adsorb fermentation inhibitors, etc. It may be necessary to consider the existence of yet another effect. The fermenter in the present invention may be appropriately stirred and mixed by a known method.

Further, since the sulfur content contained in the organic waste as the raw material is adsorbed by the activated carbon in the digestive juice, the digestive juice contains a large amount of sulfur by that amount. The liquid and organic solids in the digestive juice become organic fertilizer,
Activated carbon is used as a soil amendment material, so it is necessary to adjust the amount of fertilizer or the amount of activated carbon added when processing organic waste according to the plant to be fertilized to optimize fertilization. Can also.

This is extremely significant because it is converted to an organic fertilizer having a modifying effect. Also, when using biogas, there is a great advantage that a desulfurization device is not necessarily required. Furthermore, if rice husk charcoal is used as activated carbon, rice husk, which is agricultural waste, can be effectively used.

An increase in the generated gas yield was confirmed. There are two possible causes of this increase: the fact that the structure of the charcoal has a porous structure, thus acting as a bacterial bed, and the fact that the generation inhibiting substance is adsorbed by the substance adsorption effect of the charcoal. The concentration of hydrogen sulfide in the generated biogas was measured with a gas detector tube (GV-100 + detector tube manufactured by Gastech Co., Ltd.), and the results in Table 2 below were obtained.
