摘要
采用湿式浸渍法将MnSO4·H2O,FeSO4·7H2O,CuSO4·5H2O中的金属分次负载在陶瓷粉末表面,制备以陶瓷为载体的负载型光催化剂,用制备的光催化剂对预处理后的水性油墨废水进行光催化降解作用实验,讨论了光催化剂用量、焙烧温度、不同pH值和强氧化剂等条件对水性油墨废水降解效果。结果表明：在500℃下焙烧后的光催化剂用量为20g/L时,对pH=8-9的水性油墨废水（初始COD为4500-4600mg/L）降解效果明显,并且发现其重复使用10次左右,对水性油墨废水仍有较高的去除率。
In order to preparing ceramics as the carrier s load of photocatalyst,Wet-impregnation method was be used to load the metal of MnSO4·H2O,FeSO4·7H2O,CuSO4·5H2O in parts at the surface of the ceramic powder,and the catalysts was used to photocatalytic degradation with the pretreated water-based ink wastewater under the UV-lamps.The authors discussed the different degradation effects under the different amount of catalyst,calcination temperature,pH value and strong oxidant,and other conditions.The results showed that the best conditions are： 500℃ calcination temperature after the amount of catalyst for the 20 g / L, pH value is 8 -9 on the water -based ink waste water （ initial concentration COD 4588 -4600 mg/ L） significantly degrading effect, and found it had be repeatedly used about 10 times, the removal rate of waste water is still high.
