沼气工程残余物资源化利用研究

Methane Project Residue Utilization Research

沼气规模化与工业化生产在解决能源问题的同时也产生了大量的发酵残余物沼液沼渣,国内外现有的沼液沼渣处理和利用方式不能及时、高效地消纳沼气工业化生产过程中所产生的大量沼液沼渣,由此产生了资源浪费和二次污染问题,已制约了沼气工业的发展。沼液沼渣富含植物生长所需的营养物质,是一种优质的有机肥。农田沼液沼渣暗灌工艺可快速、高效和大量地利用沼液沼渣,实现沼液沼渣的资源化利用。

Large-scale industrial production of biogas and energy in solving the problem has also produced a large amount of fermentation residue of biogas slurry residue,the existing domestic and international processing and use of biogas slurry residue method can not be timely,efficient industrial production of dissolved methane process generated a large number of biogas slurry residue,the resulting waste of resources and the secondary pollution problems,the problem has restricted the gas industry.Biogas slurry residue rich in nutrients required for plant growth,is a high quality organic fertilizer.Dark farmland irrigation technology biogas slurry residue may be fast,efficient and a lot of use of biogas slurry residue,biogas slurry residue to achieve resource utilization.
