摘要:
用自制的椰壳活性炭作为载体制备CuO-CeO2/CSAC催化剂处理酸性大红GR染料废水.正交实验优化了CuO-CeO2/CSAC制备的工艺参数,单因素和响应面联合实验优化了CuO-CeO2/CSAC处理酸性大红GR废水的工艺条件.实验结果表明:CuO-CeO2/CSAC的最佳制备工艺参数为τ=2.50 h,T=300.0 ℃,V1=15.0 mL,V2=5.0 mL,其对CODCr和色度的降解率比单组分CuO/CSAC催化剂分别提高了62.4%和69.7%.CuO-CeO2/CSAC在室温下处理模拟废水的最佳条件为τ=4.12 h,m=0.57 g,pH值为5.0,可将CODCr和色度分别从 962.0 mg·L-1和32 720.0倍降解至35.2 mg·L-1和12.7倍,相应的降解率为96.30%和99.96%.建立的分别以CODCr和色度残余质量浓度为响应值的工艺模型与实验结果吻合较好,可预测不同工艺条件下降解CODCr和色度的效果.
Abstract:
CuO-CeO2/CSAC catalyst is prepared by using self-made coconut shell activated carbon as carrier to treat acid bright red GR dye wastewater.The preparation parameters of CuO-CeO2/CSAC are optimized by orthogonal experiment.Single factor combined with response surface experiment are used to optimize the processing conditions of the treatment of acid scarlet GR wastewater by the prepared CuO-CeO2/CSAC catalyst.The results show that the optimum process parameters of the CuO-CeO2/CSAC preparation are τ= 2.50 h,T= 300.0 ℃,V1=15.0 mL,V2=5.0 mL,and its degradation rates of CODCr and chromaticity are 62.4% and 69.7% higher than those of single component CuO/CSAC catalyst.The optimal condition for treatment of simulated wastewater by CuO-CeO2/CSAC at room temperature are τ=4.12 h,m=0.57 g,pH=5.0,and the CODCr and chroma are degraded from 962.0 mg·L-1 and 32 720.0 times to 35.2 mg·L-1 and 12.7 times,respectively.The established process models with CODCr and chromaticity residual concentration as the response values are in good agreement with the experimental results,which can predict the effects of CODCr and chroma degaradation under different process conditions.
