农户地下沼气池与地上厕所、猪圈(牛圈)在建筑上形成整体,发酵料液按设定线路循环流动,从而构成了“三结合”式沼气系统。它具有省地、省力、省水、产气多的优点。1.池型与主池半径养2头奶牛1头猪的户,池容积定为8立方米,主池半径1.35米。超过2头奶牛的户,池容定为10立方米,主池半径1.5米。一律采用西北农林科技大学邱凌设计的旋流布料自动循环型高效沼气池。2.池址与出料口座向农户宅院南北向,后院空地宽4.5米以上的,池建在后院东北角,为两厕式。出料口留向东面。宅院太小的户,在南院墙外东角建池,为单厕式。出料口留向西面。池上建厕所和猪圈时,要考虑增设预留奶牛粪便入池口的位置。
The farmer’s underground biogas tank and the toilet on the ground, the pigsty (cattle ring) form a whole in the building, and the fermented liquid material circulates according to the set route, thus forming the “three combined” biogas system. It has the advantages of saving land, saving labor, saving water and generating more gas. 1. Pool type and the main pool radius 2 pigs 2 pigs, the pool volume set at 8 cubic meters, the main pool radius of 1.35 meters. More than two cows households, pool capacity set at 10 cubic meters, the main pool radius of 1.5 meters. Will be used in Northwest Agriculture and Forestry University of Science and Technology Qiu Ling swirl fabric automatic recycling efficient biogas digesters. 2. Pool site and the outlet to peasant homes north-south, the backyard space 4.5 meters wide and above, the pool built in the northeast corner of the backyard, for the two toilets. The outlet to the east. House is too small house, built in the east wall of the south hospital wall pool, a single toilet. Outlets to the west. When setting up toilets and pigsty on the pond, it is necessary to consider setting up a place for reserving cow dung into the pond.
