我们地处北纬44°附近,气候干旱寒冷,“三口”水压式沼气池在这里存在产气率低、利用时间较短等缺点。为了解决这些问题、我们通过二年试验,研究成功了一种简易太阳能单孔沼气池。1983年在宝泉村建了3个,1984年又在兴隆庄村建了12个,全部获得成功。此种池型除了具有“三口池”的一般功能外,还有产气率高、施工简便、成本低、占地面积小、易保温、安全等优点,在北方地区有一定使用价值。
We are located near 44 ° N latitude, arid and cold climate, “three” hydraulic biogas digesters here there is a low gas production rate, short use of shortcomings. In order to solve these problems, we passed the two-year test to study the success of a simple solar one-hole digester. Three were built in Baoquan Village in 1983, and another 12 were built in Xinglongzhuang Village in 1984, all of which succeeded. In addition to the general function of “three pools”, this pool type has the advantages of high gas production rate, simple construction, low cost, small area, easy insulation and safety, and has certain use value in the northern area.
