Method for the degradation of harmful substances in water by means of hydrogen peroxide under UV irradiation

摘要

The degradation of harmful substances in water by compounds, such as hydrogen peroxide, which form hydroxyl radicals under UV irradiation in continuous reactors is improved when the irradiation is carried out in a reactor with a specific reactor volume of at least 10 liters per kW of the UV radiator or radiators, and if the amount of water to be treated is 0.25 to 25 times the amount of the intrinsic volume of the reactor flows through the reactor per hour. It is particularly preferred that the water volume per hour to be treated is 0.25 to 10 times the intrinsic reactor volume.
