Title:
カルシウム塊を含む有機性廃棄物の処理システム
Document Type and Number:
Japanese Patent JP4666606
Kind Code:
B2
Abstract:
To provide a system for treating calcium mass together with organic wastes with a low load on environments.
Calcium mass C is separated from calcium mass C-containing organic wastes A and after the separation, the organic wastes A are decomposed into biogas G and digested liquid D by methane fermentation and the separated calcium mass C is loaded to a storage tank 2 together with an aqueous high-pressure solution of carbon dioxide CO2in the biogas G and/or the digested liquid D. Alternatively, calcium mass C-containing organic wastes A are loaded to a storage tank 2 together with an aqueous high-pressure solution of carbon dioxide CO2to dissolved the calcium mass C and the organic wastes A remaining after the dissolution are decomposed into biogas G and digested liquid D by methane fermentation and the carbon dioxide CO2in the biogas G and/or the digested liquid D may be turned back to the storage tank 2 for reuse. As the storage tank 2, a deep layer type storage tank 2a in which pressure sufficient to dissolve carbon dioxide CO2in the bottom end is obtained can be used.
