METHOD OF PROCESSING UNTREATED DRINKING WATER CONTAMINATED WITH ORGANIC SUBSTANCES

摘要

Described is a method of processing untreated drinking water contaminated with organic substances, in particular water containing nitrates and plant-protection agents, by exposure to UV light. The method is characterized in that the untreated drinking water is either a) exposed to UV light at a wavelength greater than 230 nm or b) UV light with some of its wavelength components shorter than 230 nm is used in conjunction with nitrite-destroying substances. A particularly suitable device for carrying out the method comprises filters, located in the beampath between the UV lamp and the water, which allow UV light of wavelength 230 nm and above to pass. Also suitable are UV lamps which produce substantially no UV radiation of less than 230 nm.
