Abstract:
Process for the continuous operation of a system for the treatment of organically contaminated waste water in a reactor with an upstream heat exchanger and at least one nozzle system by the addition of a radical starter, a catalyst and an O.sub.2 -containing gas, the process comprising steps of:preheating the waste water in a heat exchanger;injecting the waste water through the nozzle system that comprises a motive jet nozzle into the reactor as a motive jet (TS),adding a radical starter and a catalyst to a reactor circulation flow with an intake pump thus conducting them to the motive jet,adding an O.sub.2 -containing gas to the motive jet, thereby producing an unstationary flow and starting and maintaining a radical chain reaction, wherein in this chain reaction a superimposition of the radical chain reaction initiated by the radical starter and of the O.sub.2 chain reaction initiated by the O.sub.2 -containing gas occurs, as a result of which the catalyst cyclically changes its valence and wherein the degradation of the waste water organic contaminants to be oxidized is thereby effected.
