摘要

Wastewater treatment method, characterized in that a solution of a caustic alkali in water is established in a treatment system that is connected to outlets of 1 or more wastewater receivers and to washings of the receivers, being the concentration of sufficient caustic alkali to make the solution germicidal; This is discharged from the system at the inputs to the required extent and the resulting solution plus wastewater is subsequently received in the system; the caustic alkali reacts with the wastewater, dissociates it and sterilizes it, keeping the concentration of the solution approximately constant by supplying additional caustic in the system to replace the one that reacts with the wastewater, and keeping the total amount of liquid in the system; and the dissociation of the cellulosic material included in the wastewater is accelerated by passing the solution plus said waters through a shredder.
