近年来,沼气工程发展迅速。然而对于大多数畜禽养殖场沼气工程排放的大量沼液缺乏足够的土地进行消纳,沼渣沼液的处置已成为制约沼气工程正常运行的瓶颈问题。(一)沼液特性畜禽粪污经厌氧消化后产生的沼液,其总固体含量1%~2%,既含有大量氮、磷、钾等常量元素,又含有多种微量元素、水解酶、氨基酸、有机酸、腐殖酸、生长素、赤霉素、B族维生素、细胞分裂素及某些抗菌素等生物活性物质,具有
In recent years, biogas projects have developed rapidly. However, a large amount of biogas discharged from most biogas projects in livestock and poultry farms lacks enough land for consumption. The disposal of biogas slurry has become a bottleneck that restricts the normal operation of biogas projects. (A) characteristics of biogas slurry Biogas slurry produced by animal manure after anaerobic digestion, the total solids content of 1% to 2%, both containing a large number of nitrogen, phosphorus and potassium elements, but also contains a variety of trace elements, hydrolysis Enzymes, amino acids, organic acids, humic acid, auxins, gibberellins, B vitamins, cytokinin and some antibiotics and other bioactive substances, with
