| 目的 研究光催化氧化法处理胶印油墨废水，实现胶印油墨废水的达标排放。方法 首先对胶印油墨废水进行混凝预处理，降低油墨废水浊度，然后采用光催化氧化法降解胶印油墨废水，寻求光催化氧化法处理胶印油墨废水的最优条件。结果 在催化剂的质量浓度为0.4 g/L，紫外光照时间为40 min，pH值为5时，采用光催化氧化法降解胶印油墨废水时达到最优，废水中的COD和色度的去除率分别达到90.3%和93.4%。结论 光催化氧化处理胶印油墨废水的方法切实可行，符合绿色印刷要求。 |

| The work aims to study a treatment of offset printing ink wastewater by photocatalytic oxidation process, so as to achieve the standard discharge of the offset printing ink wastewater. First, the offset printing ink wastewater was pretreated by coagulation method to reduce the turbidity. Then, the offset printing ink wastewater was degraded by photocatalytic oxidation process and the optimal conditions for such treatment were explored. When the mass concentration of catalyst was 0.4 g/L, UV-light radiation time was 40 min and pH value was 5, the degradation of offset printing ink wastewater by photocatalytic oxidation process was optimal, with COD and chroma removal rate of the offset printing ink wastewater respectively reaching 90.3% and 93.4%. The photocatalytic oxidation process used to treat offset printing ink wastewater is feasible and conforms to the requirements of green printing. |
