本试验研究了地上液体循环粪草分离式沼气池(总容积为5m~8)和地下气液循环粪便分离式沼气池(总容积为7m~3)发酵。其发酵工艺是将秸秆及其他富含纤维素的业废弃物投入草池,粪池为主发酵池,与厕所相通。两池以管道相联。利用产气和用气所造成的池体间的压差,使两池间产生气—液流动。以单向阀控制气液流向。地上液体循环粪草分离式沼气池在90天内总产气量为178.95m~3,平均日产气量为1.988m~3、平均池容产气率为0.397m~3/m~3.日;平均料容产气率为0.45m~3/m~3.日.地下气液循环粪草分离式沼气池从6月1日至11月10日的155天内共产气343m~3,平均池容产气率为0.316m~3/m~3.日;料容产气率为0.357m~3/m~3.日。
This experiment studied the fermentation of the underground liquid biogas digested by waste cycle (total volume 5m ~ 8) and the underground biogas digester (total volume 7m ~ 3). The fermentation process is straw and other cellulose-rich industrial waste into the straw pool, septic tank-based fermentation tank, and toilets are connected. Two pools are connected by pipes. The use of gas and gas caused by the pressure difference between the pool, so that between the two pools of gas - liquid flow. A one-way valve to control the flow of gas and liquid. On the ground, the liquid biogas digester with separate circulation in the 90 days had a total gas production of 178.95m 3, an average daily gas production of 1.988m 3 and an average gas production capacity of 0.397m 3 / m 3. Gas production rate of 0.45m ~ 3 / m ~ 3.During the underground gas-liquid cycle dregs separate biogas digesters from June 1 to November 15 within 155 days of co-gas 343m ~ 3, the average capacity of the gas pool The rate was 0.316m ~ 3 / m ~ 3. The gas production rate was 0.357m ~ 3 / m ~ 3.
