摘要:
以TiO2-P25作为光催化剂,250 W高压汞灯为光源,对硝基C酸废水和预处理后的废水进行了光催化降解实验,研究了初始浓度和酸度、溶液的pH值、催化剂用量以及外加氧化剂用量等因素对有机物降解效果的影响.结果表明,溶液的初始浓度和酸度、pH值、催化剂用量以及外加氧化剂用量等对硝基C酸废水的降解效果影响较大.预处理前的废水COD为2 050 mg/L、酸度(以H2SO4计)为31.2 g/L、初始pH为0.26、催化剂用量为0.3 g/150 mL,外加氧化剂K2S2O8量为0.5 g/150 mL,紫外光照射4 h去除率为41.3%;预处理后的废水COD为518 mg/L、酸度26.5 g/L、初始pH为0.75,当催化剂TiO 2-P25用量为0.1 g/150 mL溶液时,光照4 h去除率达到68.4%.
