Treatment Step

The continuous ozonation of polycyclic aromatic hydrocarbons (PAH) was studied in a two stage ozonation system followed by serobic biological degradation. The highly condensed PAH benzo(e)pyrene and benzo(k)fluoranthene were oxidized selectiely in synthetic oil/water-emulsions. The influence of the ozone mass transfer gas-liquid on the reaction rate of benzo(k)fluoranthene was studied for process optimization. The dissolved ozone concentration is influenced by temperature to a higher degree than the reaction rate of PAH. In dependence on pH, PAH oxidation occurs by a direct reaction with ozone inside the oil droplets. Two main ozonation products of benzo(e)pyrene were quantified at different retention times during ozonation and their transformation could be shown in the biological treatment step.

Based on the principle of solid phase extraction and the purification method using Florida silica, sixteen various kinds of polycyclic aromatic hydrocarbons such as naphthalene, acenaphthene and fluorene were measured in Urumqi snow by means of HPLC. The results showed that the concentration of PAHs was different in different sampling sites in Urumqi. The total concentration of PAHs was in the range of 0.2883 ~ 8.814 µg/mL and the content of PAHs snow was higher than that in water, which indicated that the snow was polluted by organic matters to a certain degree and the pollution was not so serious compared with the groundwater. So the snow has a certain application value for life.
