| 摘 要： | 采用青饲料和配合饲料饲喂生猪,对所产生的猪粪进行沼气发酵,测试和分析沼肥中主要重金属的含量,初步探索出沼肥中重金属含量的变化趋势.分析数据表明:配合饲料沼渣中砷、镉、铬的含量远高于青饲料沼渣,两者沼液中汞、铅的含量呈显著性差异.

| Abstract: | Feeding the live pig with green fodder and formular feed respectively,the corresponding two kinds of pig manure were fermented for biogas production,then tested and analyzed the content of main heavy metals in the biogas manure,the heavy metal content and its change trend were pre-liminarily studied.The analysis data showed that the contents of As,Cd and Cr in biogas residue from formular feeding were all much higher than that from green fodder feeding,at the same time,the contents of Hg and Pb in both of t... |
