  • 摘要: 以粉煤灰为载体,制备铁/粉煤灰负载型催化剂,并利用该催化剂催化H2O2氧化降解活性黄染料废水,探讨了H2O2投加量、催化剂投加量、染料初始浓度和初始pH值等因素对染料废水COD去除率和脱色率的影响。结果表明,当染料废水COD初始浓度为200 mg/L,初始pH值为1.7,投加0.5 g/100 mL催化剂及加入1.0 mL浓度为1.13 mol/L的H2O2溶液时,处理效果最好,此时染料废水的COD去除率和脱色率分别达到63%和99%,并且废水的可生化性得到很大的提高。利用该负载催化剂能够有效地减少活性黄染料废水中Fe3+的残留量。
    Abstract: Ash fly supported iron ion catalyst was prepared by using ash fly as a carrier. Its catalysis effect on oxidizing reactive yellow dye by H2O2 was studied. And the effects of dosage of H2O2, catalyst loading, initial reactive yellow concentration and solution pH on the removal rate of COD and the discoloration rate were investigated. The results show that the removal rate of COD and the discoloration rate can reach 63% and 99%, respectively under the optimal conditions of initial COD concentration of 200 mg/L, pH of 1.7, catalyst of 0.5 g/100 mL and 1.13 mol/L H2O2 of 1.0 mL,and the biodegradability of the wastewater can be greatly improved. The residues of Fe3+ in aqueous solutions can be reduced effectively when using the supported catalysts.
