This study analyzed the composition of the anaerobic fermentation residues(AFR) from different biogas digesters to provide data for the safe utilization of the material.The results showed that ① all nutrients in the biogas liquid were significantly lower than those in the sediment,especially in regard to the organic matters,humic acid,crude fiber,vitamin C and dry matters found in the liquid which were merely 2-5% of those in the residue;② the hygienic indices of the biogas liquid were… CONTINUE READING
