Experiment was conducted on the fabricated biodigester of capacity 30 l. Slurry of cow manure in water was fed through the inlet until the digester is about 80% filled with slurry, and the slurry surface on both inlet and outlet did not leave holes by which the air can get into the digester. This was to ensure the anaerobic condition in the gas space inside the digester. After the first filling, both the inlet and outlet were covered and gas valve to the gas holder was opened. In the first 20 days, the gas holder expanded with produced gas. The first 20 days was the transient phase of the biogas production and it acted as a batch reactor. At the end of 20 days, the content of the gas holder was released as it did not burn due to the predomination of carbon dioxide. The next phase was started wherein the biodigester was fed periodically with slurry including kitchen and domestic waste from the M.S. Ramaiah Institute of Technology college canteen and hostels. After the digester was operational for several weeks (in reactor from which inoculation charge is obtained) and after the initial filling, the pH value had reached the stable value of 6.5 that remained constant during the period of sampling. The temperature was constant between 35 to 40 during the day and 25 to 30 during the night. Therefore, those two parameters were considered as the constants with respect to the model development. Based on our field data, those two parameters did not fluctuate significantly in Bangalore climate (where plug flow reactor is operated).

使用小型活塞流反应器生产沼气并计算可降解固体废物的尺寸

对容量为30 l的人造生物消化器进行了实验。将牛粪在水中的浆液通过入口进料，直到消化池中约80％的浆液充满为止，并且入口和出口处的浆液表面都没有留下孔，空气可以通过这些孔进入消化池。这是为了确保消化池内气体空间的厌氧条件。第一次填充后，入口和出口都被盖住，通向储气罐的气阀被打开。在最初的20天里，储气罐中产生的天然气膨胀了。前20天是沼气生产的过渡阶段，它充当分批反应器。20天后，由于二氧化碳占主导地位，气体保持器的内容物未燃烧，因此释放了气体保持器。下一阶段开始，其中定期向生物消化器喂食MS Ramaiah理工学院大学食堂和旅馆提供的包括厨房和生活垃圾的浆料。在蒸煮器运行几周后（在反应器中可获得接种电荷），并且在初始填充后，pH值已达到6.5的稳定值，在采样期间保持恒定。温度在白天恒定在35至40之间，在夜间恒定在25至30之间。因此，这两个参数被视为关于模型开发的常数。根据我们的现场数据，这两个参数在班加罗尔气候（使用活塞流反应器运行）中没有明显波动。拉玛亚理工学院大学食堂和旅馆。蒸煮器运行数周后（在反应器中可获得接种电荷），初始填充后，pH值达到稳定值6.5，在采样期间保持恒定。温度在白天恒定在35至40之间，在夜间恒定在25至30之间。因此，这两个参数被视为关于模型开发的常数。根据我们的现场数据，这两个参数在班加罗尔气候（运行活塞流反应器的地区）中没有明显波动。拉玛亚理工学院大学食堂和旅馆。蒸煮器运行数周后（在反应器中可获得接种电荷），初始填充后，pH值达到稳定值6.5，在采样期间保持恒定。温度在白天恒定在35至40之间，在夜间恒定在25至30之间。因此，这两个参数被视为关于模型开发的常数。根据我们的现场数据，这两个参数在班加罗尔气候（使用活塞流反应器运行）中没有明显波动。5在采样期间保持不变。温度在白天恒定在35至40之间，在夜间恒定在25至30之间。因此，这两个参数被视为关于模型开发的常数。根据我们的现场数据，这两个参数在班加罗尔气候（使用活塞流反应器运行）中没有明显波动。5在采样期间保持不变。温度在白天恒定在35至40之间，在夜间恒定在25至30之间。因此，这两个参数被视为关于模型开发的常数。根据我们的现场数据，这两个参数在班加罗尔气候（使用活塞流反应器运行）中没有明显波动。
