摘要：
Changes in concentration of total organic carbon in natural organic matter during UV irradiation have been examined, and especially its biodegradable fraction. The studies have shown better effectiveness of elimination of organic substances for highly contaminated water than that obtained for pre-treated water. UV irradiation assured the decrease of all fractions of total organic carbon, which indicates the domination of mineralization over the transformation of multi-molecular substances into simpler ones. This means that organic substances were mineralised during UV irradiation. The effective elimination of non-biodegradable dissolved organic substances absorbing UV radiation ensures a very large decrease in potential of disinfection of by-products.
