| Abstract: | Degradation of an anthraquinone dye, disperse blue E‐4R, by zero‐valent iron (ZVI)/ozone (O3) was carried out in a series of laboratory‐scale experiments. The obtained results indicated that this method was much more effective than single ZVI or single O3 at removal of color, chemical oxygen demand, total organic carbon, and adsorbable organic halogen. The effect of several related operational parameters, including O3 dosage, zero valent iron dosage, temperature, pH value, and ZVI particle size were also discussed. Finally, we tried to decontaminate some actual samples with this method, which showed high treatment efficiency to the sample pretreated by conventional activated sludge. |
