Design and Construction of Ecological Cattle Production Models Linked by Biogas Production

Three types of ecological cattle production models were introduced here.Northwest orchard type is composed of biogas reactor pool,solar heating cattle feedlot,sanitation toilet,water collection pool and water-saving irrigation system.North type is composed of biogas reactor pool,toilet,cattle feedlots and greenhouse,and South type is a combination of cattle feedlot,biogas pool and orchard.In those systems,cattle manure was used for biogas production and the biogas,liquid residue and solid residue of biogas production were all comprehensively utilized.Technological routes,basic components,system running,supporting techniques and economic benefit of these systems were thoroughly analyzed.
