在国家及相关部门的重视下,我国沼气工程发展迅速,沼气作为新能源为我国农村地区能源供应作出了重要的贡献。与此同时,作为沼气工程的副产物沼渣、沼液,其产生量大、养分含量高,是理论上的良好有机肥源,但在实践中未能得到较好的利用,有的地方因沼渣、沼液随意排放甚至成了新的污染源。沼渣、沼液不能得到有效利用,涉及到的机制、技术原因很多,其中沼渣沼液不分、状态粘稠、施用不易是重要的原因之一。尤其是在有
Under the attention of the state and relevant departments, biogas projects in China are developing rapidly. As a new energy source, biogas has made an important contribution to the energy supply in rural areas in China. In the meantime, biogas residue and biogas slurry, which are by-products of biogas projects, are large in quantity and high in nutrient content and are theoretically good organic fertilizer sources, but they have not been well utilized in practice. Biogas residue, biogas slurry discharged or even become a new source of pollution. Biogas residue and biogas slurry can not be effectively utilized. The mechanisms and technical reasons involved are numerous. Among them, biogas slurry and biogas slurry are not divided into many parts, and their status is viscous. Application is not easy to be one of the important reasons. Especially in there
