ABSTRACT:
A process and device for combined oxidation of polluted water, e.g. industrial waste water or effluents, to make it suitable for drinking, involves injection of hydrogen peroxide (pure aqueous solution or diluted) and ozone (gaseous, or ozonized oxygen or air) simultaneously and in a flow direction co-current with the circulation of the water to be treated, at the inlet of the oxidation reactor. For example, a reactor is endowed with mechanisms to inject ozone and hydrogen peroxide at its base, at very closely-spaced points and simultaneously, in a flow direction the same as the water to be treated, with an automatic control system to regulate the levels of the oxidizing agents.
