摘　　要：Cu-O/FSC是一种优化制备的负载型催化剂,实验中以其催化湿式氧化处理模拟印染废水,考察焙烧条件对催化剂的影响。以水样COD去除率和脱色率评价催化剂的活性、以处理出水Cu溶出浓度评价催化剂的稳定性,通过AA、XRD、SEM等研究了焙烧温度和时间对催化剂性能、物相及形貌等的影响。结果表明:随着焙烧温度的提高和焙烧时间的延长,催化剂活性降低、稳定性提高;催化剂的比表面和孔容随着焙烧温度的提高而减少;适宜的催化剂焙烧温度和时间分别为650℃和5h。Cu-O/FSC is a optimized supported catalyst that was used to dispose printing and dyeing simulant wastewater with catalytic wet oxidation technology,and the influence of calcination condition on catalyst was investigated.The catalyst activity was evaluated with COD removal rates and colour removal rates,and the catalyst stability was evaluated with Cu lixiviated concentration.The influence of calcination temperature and time on the capability,phase,morphology of catalysts were investigated by the means of AA,XRD,SEM and so on.The experiments results showed that the catalyst activity played down and the stability increased with the increase of calcination temperature and time;The surface area and porosity reduced with the increase of calcination temperature;As Cu-O/FSC catalyst,the optimized calcination temperature and time was 650 ℃ and 5 h,respectively.
