目前我国农村家用沼气池的活动盖,大都按“国标”图集的标准和规程,用钢筋混凝土制作,由于建材所限,显得十分笨重,启闭操作不便,且因精密度要求高,手工制作很难达到规格标准,安装后易被池内气压冲开,密封性能差,漏气现象较普遍,影响了沼气池的管理和使用。针对上述问题,江西省安义沼气试验站于 At present, the activities of rural household biogas digesters in our country are mostly made of reinforced concrete according to the standards and procedures of the “national standard” atlas. Due to the limitation of building materials, they are very heavy and inconvenient to open and close. Due to the high precision requirements, hand-made Difficult to meet the specifications, easy to be opened after the pool pressure, poor sealing performance, leakage is more common, affecting the digester management and use. In response to the above problems, Jiangxi Anyi biogas test station at
