Abstract

Organic substances in biologically pretreated waste water are oxidised by ozonising with an ozone-containing gas in at least two reaction vessels (1, 2) connected in series and UV irradiation in a UV reactor (5). To reduce the size of the reaction vessels and decrease the specific ozone consumption, the reaction vessels through which the waste water successively flows are operated at pressures increasing from vessel to vessel. The ozone-containing gas flows through the vessels in counter-current to the waste water. The introduction of the ozone-containing gas from one reaction vessel to the subsequent reaction vessel proceeds as a result of the pressure drop. <IMAGE>
