目的 研究一种具备吸附和降解作用的催化剂，进而更高效地净化处理油墨废水。方法 通过氧化还原沉淀法对天然斜发沸石进行MnOx改性，并研究天然斜发沸石和MnOx改性的斜发沸石对油墨废水进行净化处理。考察MnOx改性斜发沸石的晶型、孔结构和形貌，系统地研究处理时间和处理温度对油墨废水COD和色度去除率的影响规律。结果 MnOx改性的斜发沸石保持了斜发沸石的晶型结构和形貌，具有更高的比表面积、孔容量，以及更宽的孔径分布。结论 在最佳的处理条件下，与天然斜发沸石相比，MnOx改性斜发沸石具有更高的去除性能，在20 ℃下对油墨废水处理15 min，其COD和色度去除率分别可以达到98%和99%以上。

The work aims to study a catalyst with adsorption and degradation for more efficient purification of ink wastewater. Through redox precipitation method, the natural clinoptilolite was modified by MnOx, and the natural clinop-tilolite and MnOx modified clinoptilolite were studied to purify the ink wastewater. The crystal form, pore structure and morphology of MnOx modified clinoptilolite were investigated. The effects of treatment time and treatment temperature on COD and chroma removal rate of ink wastewater were systematically studied. The results showed that, the MnOx modified clinoptilolite maintained the crystal structure and morphology of clinoptilolite, and had higher specific surface area, pore volume and wider pore size distribution. Under the optimal treatment conditions, the MnOx modified clinoptilolite has higher removal performance than the natural clinoptilolite. The COD and chroma removal rates of ink wastewater can reach over 98% and 99% at 20 ℃ for 15 min.
