H_2O_2催化湿式氧化酸性红B染料废水的研究

On the Acid Red B-containing Water by Catalytic Wet Peroxide Oxidation

以自制的复合氧化物Fe2O3-NiO-CeO2/γ-Al2O3为催化剂氧化降解酸性红B染料废水,考察了进水pH值、反应温度、氧化剂及催化剂用量对COD去除率的影响。结果表明,在反应温度为90℃,进水pH为7,催化剂投入量2g(300mL废水),双氧水用量18mL时,酸性红B的COD去除率可达到87.6%。

The Acid Red B-containing water was degraded by wet peroxide oxidation method using Fe2O3-NiO-CeO2/γ-Al2O3 as catalyst,and the effect of reaction temperature,oxidant and catalyst dosage on the COD removal were studied.Results show that 87.6% of COD removal can be obtained under the condition of 90℃,pH=7,2g catalyst（300 mL waster water） and 18mL H2O2.
