摘要:采用动态连续处理装置研究颗粒活性炭（GAC）催化H2O2氧化活性红X-3B染料（RRX-3B）的效能以及GAC表面吸附污染物对催化性能的影响，考察GAC与Fe2+协同催化作用。研究结果表明：RRX-3B的处理效果随着流速的增加而逐渐降低；新GAC/H2O2体系降解效果优于单独GAC吸附与单独H2O2氧化，GAC重复使用存在部分失活现象使其脱色率和COD去除率下降，且表面预先吸附污染物的GAC在重复使用过程中下降更为明显；固定H2O2投加量为5 mmol·L-1，按n（Fe2+）：n（H2O2）为1:20投加Fe2+，GAC与Fe2+联合体系能持续有效使RRX-3B氧化脱色，重复使用4次后脱色率仍可达99.65%，GAC和Fe2+之间存在协同催化H2O2降解RRX-3B的作用。GAC表面附着的Fe2+能够加强催化作用，且有效延长其使用寿命。

Abstract:By using granular activated carbon (GAC) to catalyze H2O2 oxidation reactive red X-3B (RRX-3B), the catalytic effect GAC in dynamic and continuous treatment equipment and the influence of adsorbed pollutants catalytic performance of GAC was studied. The synergistic catalysis of GAC and Fe2+ was also explored. The results showed that the degradation effect of reactive red dye wastewater is gradually reduced with the increase of flow velocity. The degradation efficiency of the new GAC/H2O2 system was better than that of the separate GAC adsorption and the separate H2O2 oxidation. The reuse of activated carbon resulted in partial inactivation, which made the decolorization rate and COD removal rate decrease, and the removal rate of GAC with surface attachment pollutants decreased more obviously during the reuse process. The dosage of fixed H2O2 was 5 mmol·L-1, and the amount of Fe2+ was added according to n (Fe2+):n (H2O2) equal to 1:20. The combined system of GAC and Fe2+ can persistently and effectively oxidize the decolorizing RRX-3B, and the decolorization rate still reaches 99.65% when the GAC is reused for 4 times. There is a synergistic effect between GAC and Fe2+ on the degradation of RRX-3B by H2O2. The Fe2+ adsorbed on the surface of GAC can enhance the catalytic activity and prolong the service life of GAC effectively.
