由吉林省农科院土肥所研制的铁沼气罐及干发酵工艺于去年十月通过省级鉴定。与会专家认为,铁沼气罐容积小,用水量少、进出料方便安全、节省劳力。由于长期处于中温状态,利于杀死粪便原料中的虫卵病菌。铁沼气罐采用干发酵,因此发酵后的沼渣作为肥料,便于保存、运输和施用。在我省西部(白城地区)干旱、太阳能资源丰富、缺砂石地区,适宜推广铁沼气罐及发酵工艺。建议我国内蒙古及西北干旱地区试用本装置及发酵工艺。一、铁沼气罐的制作铁沼气罐用2.0—3.0毫米的铁板焊接而成,铁罐为圆柱形,卧置,容积为2立方米(圆柱直径为1.14米,长2米),在罐体中部设有砝兰盘的长方形口(长为厘60米,宽为45厘米),作为进出料口,该口 The iron biogas tank and dry fermentation process, developed by the Soil Science Institute of Jilin Academy of Agricultural Sciences, passed the provincial appraisal in October last year. Participating experts believe that ferromanganese gas tank small volume, less water, convenient access to materials safe, save labor. Due to the long-term in the warm state, help to kill the oocysts in stool raw materials. Iron biogas tank with dry fermentation, fermentation residue as fertilizer, easy to save, transport and application. In the western part of our province (Baicheng area) arid, rich in solar energy resources, lack of gravel area, suitable for the promotion of iron biogas tank and fermentation process. It is suggested that this plant and fermentation process should be tried in the arid areas of Inner Mongolia and Northwest China. First, iron biogas production Iron biogas tank with 2.0-3.0 mm iron welded together, cans cylindrical, lying, volume of 2 cubic meters (cylindrical diameter of 1.14 meters, 2 meters long), in the tank The middle of the body with a rectangular plate of imperial Lan (length of 60 centimeters long, 45 centimeters wide), as the inlet and outlet, the mouth
