Plant for the production of phosphate salts and biological wastewater treatment plant and process for the operation of these plants

摘要

The invention relates to a plant (10) for separating phosphate from phosphate-containing liquids and obtaining phosphate salts with one or more reactors (12), each comprising two electrodes of opposite polarity and spanning a reaction space between them, each reactor (12) one Inlet (14) and a drain (16), in which the outlet (16) in a recirculation (22) and an outflow (24) is separated and the recirculation (22) part of the liquid of the outlet (16) of the reactor (12) to the inlet of the same or another reactor (12) supplies and a method and a biological treatment plant and a method for their operation.
