Fe_2O_3/凹凸棒土催化氧化处理印染废水的研究

Study on Preparation of Fe_2O_3/attapulgite Catalysts for Dyeing Wastewater

研究由浸渍法制备负载型Fe2O3/凹凸棒土催化剂,并利用该催化剂对印染废水进行处理,探讨废水pH值、催化剂用量、反应时间等对色度去除率的影响。确定较佳反应条件:催化剂用量为0.25g,染料废水初始浓度300mg/L,染料废水pH值为7.0,过氧化氢0.6mL,反应时间2h时色度去除率为90%。

Fe2O3/attapulgite catalysts were prepared catalyst concentration and the time of reaction influenced by impregnation. the treatment of Experimental results showed that the pH value, dyeing wastewater. The optimal conditions were determined as follows： dosage of the catalyst was 0.25g,primary concentration of dyeing wastewater was 300mg/L,primary pH of dyeing wastewater was 7.0, dosage of H2O2 was 0.6mL,the time of reaction was 2h, the color reduction was 90% in the end.
