Title: AMMONIUM REDUCTION IN WASTEWATER FROM POWER STATIONS
Abstract:
The invention relates to a power station (1) with a water-steam circuit (2), comprising an expansion container/evaporator (3) which is connected thereto via a first wastewater line (4) for the purposes of receiving and at least partially evaporating wastewater from the water-steam circuit (2) and thus utilising the heat from the wastewater or from another source (20), and comprising a first condensation stage (5) connected via a steam line (6) to said expansion container/evaporator (3), wherein a condensation recirculation line (7) branches off from the first condensation stage (5) and opens into the water-steam circuit (2). The invention also relates to a method for treating wastewater in a power station (1) with a water-steam circuit (2).
