Ozonolysis and Oxyphotolysis of Municipal and Industrial Effluents

摘要

This research deals with the tertiary treatment of effluents using 'OZONE' and the 'OZONE/U.V.' (oxyphotolysis) process. The ozone was either generated insitu at the gas-liquid interface or externally produced and fed into a novel reactor which ahs a high mass transfer efficiency. The novel reactor uses the 'Hibee' principle of enhanced mass transfer to a thin liquid film as it flows across the surface of a rotating disc. Measurements of mass transfer coefficients for ozone were compared with results calculated from empirical formula derived from previous studies on the hydro-dynamics of such a reactor. Also, tertiary treatment work was carried out and the performance of this rotating disc reactor in contracting ozone with secondary effluents was evaluated. The reactor performed well with these effluents.
