为了把国标池坚固耐用、防寒与808型太阳能水压式沼气池体积小、产气率高、进出料方便等优点结合起来,我们自83年7月在我县高什井、马赵、薛坟等大队搞了10个4立方米圆型太阳能水压式沼气池和3个袋式太阳能沼气池的试验。试验结果:在每年5—10月份期间比国标池产气量增长70—100％,甚至两倍三倍。下边分别简介一下太阳能水压式和太阳能袋式沼气池的建造工艺和效果: 一、圆型(4立方)太阳能水压式沼气池:①主体池高0.66米、上天高0.48米、下天高0.24米、上盖防冻土厚0.32米、主池直径2.4米;②夏季池拱顶不覆土而裸露(用沙子灰抹光),沿拱脚用75号混凝土筑起厚为4厘米、高为超过地平面10厘米左右的蓄水圈,
In order to combine the advantages of ruggedness and cold resistance of national standard pool with the small size of 808 solar-powered biogas digester, high gas production rate, convenient access to materials, etc., since July 2003, in Gushui, Mazhao and Xue of our county Tomb and other brigade engaged in 10 4 cubic meters of solar-powered biogas digesters and three bags of solar digesters test. Test results: during the May-October each year than the national standard gas pool production increased by 70-100%, or even three times. Below are briefed on solar water pressure and solar bag biogas construction technology and results: First, the round (4 cubic) solar-powered biogas digesters: ① main pool 0.66 meters high, 0.48 meters high, the sky high 0.24 meters, the top antifreeze thickness of 0.32 m, the main pool diameter of 2.4 meters; ② summer pool vault uncovered soil bare (with sand ash), along the arch feet with 75 concrete built up to 4 cm thick, high More than 10 cm above the ground plane of the water ring,
