摘要: 通过对不同类型的沼气工程的沼肥进行检测分析,以期为沼肥的安全利用提供借鉴.研究表明:沼液中各种营养成分明显低于沼渣,特别是有机质、腐植酸、粗纤维、维生素C和干物质含量只有沼渣中含量的2%～5%;沼液中各卫生指标明显优于沼渣,有毒有害成分明显低于沼渣.

Abstract: 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 significantly better than those of the residue,the harmful components in the fluid were significantly less than the residue.
