Co/AC催化剂的制备及CWPO处理腈纶废水研究

Co/AC Catalyst Preparation and CWPO Processing Acrylic Wastewater Research

以活性炭为载体，负载活性组分金属Co，制备了Co／AC催化剂，采用催化过氧化氢氧化技术（CWPO）处理腈纶废水，考察其催化氧化性能。实验结果表明：将预处理后的20-40目粒状活性炭浸渍于质量浓度为7％Co（NO3）2溶液中，浸渍9h后，经自然晾干，在500℃的条件下焙烧4h得到的Co／AC催化剂催化效果最好。

This paper discusses the experiment with activated carbon as the carrier,loaded Co as active component,prepares Co/AC catalyst,and uses Catalytic Wet Hydrogen Peroxide Oxidation(CWPO)to deal with acrylic fibers wastewater.The experiment indicates that when the pretreated 20-40 mesh granular activated carbonis impregnated into 7% Co(NO3)2 solution for 9 hours, through natural air-dry and 4hours calcinationin 500℃,the highest catalyst effect of Co/AC catalyst is the best.
