Processing method of shochu distilled spirit and liquid fertilizer obtained from shochu distilled spirit

摘要

PPROBLEM TO BE SOLVED: To develop a method for treating a Shochu distillation residue efficiently by relatively simple facilities without a bad influence on the environment, such as offensive odor generation and groundwater pollution; to obtain odorless liquid manure. PSOLUTION: The Shochu distillation residue is subjected to solid-liquid separation by dehydration. The separated solid is used as animal fodder, or as a soil improvement material or manure after fermentation treatment. The water produced by the dehydration is fed onto a heaped material comprising a carbon-based adsorbent, such as bark and wood waste, to be filtered and adsorbed. Thereby pollutants are removed by adsorption/decomposition. The liquid flowing out of a filter after the filtration and adsorption by the carbon-based adsorbent is used as the liquid manure.
