Abstract

In order to control pesticide pollution in water environment, ozone-fly ash combined process was studied in laboratory. Dicamba(3,6-Dichloro-2-methoxybenzoic acid) was selected as model pollutant. The reaction temperature was changed to study the degradation efficiency. The experimental results show that fly ash taken from electric field II and III of ESP (No.2 fly ash) is finer than fly ash taken from electric field I of ESP (No.1 fly ash). Dicamba degradation using O3-No.1 fly ash system is faster than dicamba degradation using O3-No.2 fly ash system at same temperature. As the temperature increases, dicamba degradation is accelerated. The degradation can be well fitted by pseudo-first-order kinetics. The pseudo-first-order rate constant increases with temperature increases either in O3-No.1 fly ash system or in O3-No.2 fly ash system. The promote performance of finer No.2 fly ash on ozonation process is better than that of No.1 fly ash.
