Abstract

PROCESS AND DEVICE FOR TREATING WASTEWATERS BY OXIDATION 5 The present invention relates to a process for treating wastewaters comprising at least one step of aerobic biological treatment of the wastewaters in a biological reactor (3), characterized in that it additionally comprises a step of ozonation during which ozone is 10 injected into one or more circuits (1, 6) arranged to transport a respective fluid into the biological reactor (3). The present invention also relates to a device relating thereto. 15 Fig. 1
