偶氮性染料之臭氧預處理對生物降解之影響(1/2)

Ozonation has become one of the most promising methods to treat industrial
wastewaters throughout the world. However, this study focuses on the effects of
pre-ozonation process on biodegradation of azo dye wastewater and subsequently to
understand the reduction mechanisms (principles) and design criteria (application)associated with the sequential batch reactor (SBR).
Ozone/oxygen mixture is produced by ozone generator, then, pumped into the
counter-current type of bubble column. Azo dye wastewater is fed from the top of
bubble column and mixed with an ozone/oxygen gas. After ozonation, azo dye
wastewater is pumped into the SBR for further biological treatment that is prepared
for biodegradation and toxicity experiments.
The objectives of this research work are intended to develop the reaction kinetics
and mass transfer model of azo dye treated by ozonation, and to determine the
optimum dose based on the chemical analysis, biodegradation of intermediates/final
products, from the SBR treatibility studies.
