    • In order to realize the treatment for an organic material anaerobically, which contains a big amount of a solid matter, and in order to deal with the organic material at a high decomposition rate and at a lower cost, the method and apparatus provides: the steps of: solubilizing the solid organic material in the organic material by alkali treatment to obtain the soluble organic material; applying acid fermentation to the organic material containing the soluble organic material, obtained in the solubilization step, by anaerobic bacteria; separating the material obtained in the acid fermentation step into the solid component and into the liquid component; applying methane fermentation to the liquid component obtained in the separation step for obtaining the digestive gas; introducing the digestive gas to the acid fermentation step, introducing the generating ammonia in the acid fermentation step into the digestive gas; and taking out the ammonia, together with the digestive gas from the acid fermentation system, thus removing the ammonia; and recycling the solid component obtained in the separation step to the solubilization step.
    • 在有机材料(1)的固体有机物用碱处理溶解。 增溶的物质通过厌氧进行酸化处理,然后进行固 - 液分离和液体成分是甲烷发酵。 所形成的消化气体(8)返回到酸化过程。 与酸发酵罐(3)被除去,固体组分返回到溶解过程中产生的氨。 一个独立的claimsoft包含有机材料的厌氧性处理装置。 该装置具有一个罐溶解(2),用于在有机材料中通过在碱处理,酸发酵罐(3),用于增溶的物质的酸化厌氧固体 - 液体分离器(4),用于酸化的物质分离成固体和液体可溶有机物质 部件,甲烷发酵槽(7),用于通过所述液体组分的甲烷发酵形成的消化气体,以及氨去除单元。 所述去除单元(通过引入消化气体酸发酵罐与酸发酵罐生产)从消化气体中移除氨。 该设备具有它返回作为固体组分返回到溶解槽的路径(6)的路径。
