Ultraviolet treatment is used for the destruction of refractory wastewater components. This paper addressed its application on the destruction of nonbiodegradable chlorophenols with the presence of different oxidants. The experiments were carried out in a batch photoreactor under various pH, dissolved oxygen (DO) time, and oxidant types and concentrations. Experimental result indicates that the dissolved oxygen levels has little effect on the destruction of chlorophenols by UV irradiation. The presence of some oxidants (e.g., H{sub 2}O{sub 2}) significantly increases the destruction efficiencies of chlorophenols by UV treatment. The reaction kinetics are studied and discussed. Proper reactor design is essential to the successful application of UV/oxidant treatment.
