重庆市沼渣沼液机械化抽排循环利用实践

Exhaust Recycling Practice of Biogas Residues Mechanical Pumping in Chongqing City

畜牧业在重庆、特别是三峡库区农村经济中占有极其重要的地位,但畜牧业规模化的发展,在创造经济效益的同时,也产生了巨大的畜禽粪便污染。结合重庆三峡库区养殖业、沼渣沼液和种植产业发展的实际,在黔江、长寿、城口等地开展了沼渣沼液机械化抽排循环利用的研究和示范。试验结果表明:沼渣沼液机械化抽排循环利用,促进了农业养殖业、种植业的循环,沼渣沼液机械化抽排循环利用从概念变成现实。

Animal husbandry in Chongqing,especially in Three Gorges Reservoir area,plays a very important role in the rural economy. But the development of animal husbandry in scale,created economic benefits at the same time,also produced a huge animal manure pollution. According to the actual development situation of aquaculture,biogas residues and planting industry in Chongqing Three Gorges Reservoir,research and demonstration of biogas manure mechanization drainage cycle utilization was carried out in Qianjiang,Changshou and Chengkou etc. Test results showed that biogas manure mechanization drainage cycle utilization promoted agricultural breeding and planting cycle. The concept of biogas manure mechanization drainage cycle utilization became reality.
