| 摘要 |
<p>The invention relates to a process for converting organic material in a microbiological way under gas generation, the conversion being carried out in a reaction vessel by means of microorganisms which are growth on a movable bed of inorganic granular material and freely in micro blocks in a continuous aqueous phase, the substrate for the microorganisms being supplied to the bed in connection with a mechanical stirrer and the gases generated by the conversion being utilized for expanding the bed, the free micro flocks being externally separated from discharged liquid and returned to the reaction vessel. The invention also comprises all apparatus for carrying out said process. including a reaction vessel, a stirrer arranged therein, means for supply of liquid containing substrate and means for discharge of liquid and for recirculation of free active material and a movable bed of inorganic granular material positioned in the reaction vessel and intended for carrying growing microorganisms.</p> |
