VERFAHREN UND VORRICHTUNG ZUR ANAEROBEN REINIGUNG VON FLUESSIGMEDIEN

摘要

In the purification of liquid waste by fermentation, intimate mixing of the liquid waste and active sludge is achieved without breakdown of the active sludge particles by shearing and without the formation of stagnant zones, by feeding the liquid waste to the fermentation zone through a plurality of mutually spaced inlets therefor and periodically interrupting or varying the flow of liquid waste through each inlet.
