我所1981年完成了沼气固体发酵的瓶试研究,结果证明方法可行,效益明显。在此基础上,于1982年进行了扩大试验。试验采用园柱形钢质罐做发酵器,发酵容积250立升。这次扩大试验的目的是继续探索沼气固体发酵工艺的技术,观察发酵在启动阶段和整个运转过程中的变化情况,测定原料转化利用率及产气率。 In 1981, I finished the bottle test of biogas solid fermentation and the results proved that the method was feasible and the benefit was obvious. On this basis, conducted in 1982 to expand the test. The test uses cylindrical steel tank fermenter, fermentation volume of 250 liters. The purpose of this expansion experiment is to continue exploring the technology of biogas solid fermentation process, observe the changes of fermentation during the start-up phase and the whole operation, and measure the conversion rate of raw materials and gas production rate.
