通过广泛的调查和分析研究,发现有几个重要问题,影响“三结合”沼气池效益的正常发挥,必须予以解决。第一个问题:很大一部分“三结合”沼气池的猪栏、牛栏和厕所的粪便,不能自动进入沼气池,而停留在进料口边,粪沟内,使地下口和猪牛栏内的粪道不能畅通。什么原因? (一) 没有落差,或落差太小。没有自动进料条件。 (二) 池内料液的浮托力,阻碍粪便流入沼气池。 (三) 公共厕所的粪沟坡度平缓,尿、粪分离,缺乏形成青苔和润滑的条件。解决办法: ①要把猪牛栏、厕所蹲位地面普遍提高70厘
Through extensive investigation and analysis, several important problems have been found. The normal operation of the benefit of the “three combined” biogas digesters must be solved. The first problem: a large part of the “three combined” digesters pigsty, bullpen and toilet excrement, can not automatically enter the digester, and stay in the feed side, ditch ditch, so that the underground mouth and pigs noodles Within the manure can not be smooth. What causes? (A) no drop, or gap is too small. No automatic feeding conditions. (B) Floating force of the liquid in the pool hinders the flow of manure into the digester. (C) of the public toilet ditches gentle slope, urine, feces separation, the lack of formation of moss and lubrication conditions. The solution: ① should be pigs bar, toilet squatting ground generally increase 70%
