抄録

Effluents containing various dyes, intermediates and auxiliaries, which are typically biorefractory, are known to have high trihalomethane formation potential (THMFP) as well as intense color. In this study, six water-soluble dyes and five intermediates were ozonated to investigate the variations of total organic halide formation potential (TOXFP) and THMFP. The decrease in color and the change in biodegradability were also studied. The variation patterns of TOXFP and THMFP were roughly divided into two groups and the values of TOXFP for dyes (intermediates) decreased to 50.0 (15.0-30.0) μg·mg total organic carbon (TOC)^-1 and that of THMFP to 20.0 (10.0) μg·mg TOC^-1 through ozonation of about 2.50 mgO₃·mg TOC^-1. The rapid decoloration and enhancement in biodegradability were attained by short-term ozonation which was incomplete to decrease TOXFP and THMFP. From the viewpoint of the removal of organic halides, long-term ozonation was found to be necessary.
