Abstract

Comparison of the efficiency of photocatalytic oxidation of aqueous solution of fulvic acids (TOC0—15.9–17.1 mg/dm3, pH0 6 ± 0.1) by oxygen of the air, hydrogen peroxide and ozone in a reactor containing a wide-porous ceramic block with immobilized TiO2 with the variation of the concentration of H2O2, feed rate of O3 and temperature showed advantages of photocatalytic ozonization and expediency of its use for deep destruction of natural organic substances in water. The maximum degree of destruction in photocatalytic systems O2/TiO2/UV, H2O2/TiO2/UV and O3/TiO2/UV constituted respectively 41, 73 and 90% for TOC for 5, 4 and 3 h.
