光催化反应器-旋转盘反应器应用于SDR耦合氧化含酚废水

光催化耦合臭氧技术作为一种先进的高级氧化技术（AOPs），在苯酚废水处理等领域展现出显著优势。在制药、煤化工、树脂厂等工业领域，这种技术对于处理含有有机污染物的废水具有极其重要的应用价值。

As an advanced advanced oxidation technology (AOPs), photocatalytic coupled ozone technology has shown significant advantages in fields such as phenol wastewater treatment. In industrial fields such as pharmaceuticals, coal chemicals, and resin plants, this technology has extremely important application value for treating wastewater containing organic pollutants.

光催化耦合臭氧技术结合了光催化与臭氧分解氧化的双重优势。光催化过程利用紫外灯等光源激发催化剂，产生具有强氧化性的活性自由基，进而降解废水中的有机污染物。而臭氧作为强氧化剂，能够直接氧化分解废水中的有机物质，进一步提高处理效果。当光催化与臭氧分解氧化技术耦合时，两者能够协同作用，产生更多的活性自由基，从而加速有机污染物的降解过程。

Photocatalytic coupled ozone technology combines the dual advantages of photocatalysis and ozone decomposition and oxidation. The photocatalytic process uses light sources such as ultraviolet lamps to excite the catalyst to generate active free radicals with strong oxidizing properties, thereby degrading organic pollutants in wastewater. As a strong oxidant, ozone can directly oxidize and decompose organic substances in wastewater, further improving the treatment effect. When photocatalysis is coupled with ozone decomposition and oxidation technology, the two can work synergistically to generate more active free radicals, thus accelerating the degradation process of organic pollutants.

在反应器设计方面，旋转盘反应器为光催化耦合臭氧技术提供了高效的反应环境。通过旋转盘的快速旋转，能够增加废水与催化剂和臭氧的接触面积，提高传质效率，从而加快反应速率。此外，旋转盘反应器还具有操作简便、易于维护等优点，适合工业化生产应用。

In terms of reactor design, the rotating disk reactor provides an efficient reaction environment for photocatalytic coupled ozone technology. The rapid rotation of the rotating disk can increase the contact area between wastewater, catalyst and ozone, improve mass transfer efficiency, and thereby accelerate the reaction rate. In addition, the rotating disk reactor also has the advantages of simple operation and easy maintenance, and is suitable for industrial production applications.

催化剂负载是光催化耦合臭氧技术的关键之一。ZnO-TiO2作为一种高效的光催化剂，具有较高的光吸收性能和稳定性。通过将其负载在适当的载体上，如SDR（旋转盘反应器）等，不仅可以提高催化剂的分散性和利用率，还可以增强催化剂与废水中有机污染物的接触效果。负载型ZnO-TiO2光催化剂在紫外灯的照射下，能够产生更多的活性自由基，从而实现对有机污染物的快速降解。

Catalyst loading is one of the keys to photocatalytic coupled ozone technology. As an efficient photocatalyst, ZnO-TiO2 has high light absorption performance and stability. By loading it on an appropriate carrier, such as an SDR (rotating disk reactor), it can not only improve the dispersion and utilization of the catalyst, but also enhance the contact effect between the catalyst and organic pollutants in wastewater. The supported ZnO-TiO2 photocatalyst can generate more active free radicals under the irradiation of ultraviolet lamp, thereby achieving rapid degradation of organic pollutants.

异质结结构是提升光催化活性的重要手段。通过将不同半导体材料结合形成异质结，可以拓宽光吸收范围，提高光生电子和空穴的分离效率。这种结构有助于增强光催化过程中的氧化还原能力，进一步提高有机污染物的降解效率。

Heterojunction structure is an important means to improve photocatalytic activity. By combining different semiconductor materials to form heterojunctions, the light absorption range can be broadened and the separation efficiency of photogenerated electrons and holes can be improved. This structure helps enhance the redox ability during the photocatalytic process and further improves the degradation efficiency of organic pollutants.

在制药、煤化工、树脂厂等工业领域，废水处理一直是环保工作的重点。这些行业的废水中往往含有高浓度的有机污染物，如苯酚等，对环境和人类健康造成潜在威胁。采用光催化耦合臭氧技术处理这些废水，可以有效地降解有机污染物，降低废水中的污染物浓度，达到环保排放标准。

In industrial fields such as pharmaceuticals, coal chemicals, and resin plants, wastewater treatment has always been the focus of environmental protection work. Wastewater from these industries often contains high concentrations of organic pollutants, such as phenol, posing potential threats to the environment and human health. Using photocatalytic coupled ozone technology to treat these wastewaters can effectively degrade organic pollutants, reduce the concentration of pollutants in wastewater, and meet environmental protection emission standards.

非均相臭氧氧化是光催化耦合臭氧技术中的重要过程。在催化剂的作用下，臭氧能够在非均相条件下与废水中的有机污染物发生氧化反应。这种反应方式不仅提高了臭氧的利用率，还增强了氧化反应的选择性和效率。通过优化反应条件，如催化剂种类、臭氧浓度、反应时间等，可以进一步提高非均相臭氧氧化的效果。

Heterogeneous ozone oxidation is an important process in photocatalytic coupled ozone technology. Under the action of a catalyst, ozone can oxidize with organic pollutants in wastewater under heterogeneous conditions. This reaction method not only improves the utilization rate of ozone, but also enhances the selectivity and efficiency of the oxidation reaction. By optimizing reaction conditions, such as catalyst type, ozone concentration, reaction time, etc., the effect of heterogeneous ozone oxidation can be further improved.

高级氧化技术（AOPs）的应用为工业废水处理提供了新的解决方案。光催化耦合臭氧技术作为AOPs的一种，具有高效、环保、适用范围广等优点。通过将这种技术应用于制药、煤化工、树脂厂等行业的废水处理中，可以实现废水的高效净化和资源化利用，为工业可持续发展做出贡献。
