HIGH RATE BIOGAS PRODUCTION METHOD BY USING AGRICULTURAL AND FISHERY BY-PRODUCT SILAGE WITH SWINE MANURE

摘要

PURPOSE: A high efficiency biogas manufacturing method is provided to increase biogas production by anaerobic-digesting silage of agriculture and fisheries byproducts. CONSTITUTION: A high efficiency biogas manufacturing method comprises the steps of: mixing fisheries byproduct and agricultural byproducts; manufacturing silage of the mixed byproducts; and anaerobic-digesting the mixed silage with pig ordure. The silage is manufactured by mixing the fisheries byproduct and brewer's grains. A mixing ratio of the fisheries byproduct and brewer's grains is 50:50 by the dry matter standard.
