沼气工程与猪场废弃物生物能开发及综合利用研究

Piggery farm residue is a large contaminating source to environment, but it is also a large resource reservior. Taking Taihua Piggery farm for an example, calculated results indicated that: for output of 3000 pigs per year, By taking biogas engineering, Taihua Piggery farm’s yearly potential bioenergy counts for more than 170 thousand RMB Yuan, which is as follows: the available biogas energy is 719.4GJ, corresponding to 96.18t coal’s energy, worth 35.6 thousand RMB Yuan; the bio-manure is worth 132.2 thousand RMB Yuan, the nutrient content of Nitrogen, Phosphorus and Potassium correspond to 27.44t Carbamide, 6.26t Calcium phosphate and 20.14t Potassium chloride. If these biomass resources cannot be utilized effectively, they will pollute the atmosphere、cropland and water area, etc. the Biogas Energy Eco- system Engineering in TaiHua piggery farm combined the breeding、planting and living fuel efficiently, Taking anaerobic biological treatment technology for the treatment of piggery residue, while the byproducts, biogas ,is used as living fuel for the country people, and the bio-manure are used for organic fertilizer to paddy and vegetable planting. So it has successfully realized resource utilization of the piggery residue, as well as treatment of the pollution ,and has made a beneficial attempt on resource utilization of piggery residue.
