Ozone (O(3)) has been used successfully in advanced wastewater treatment in paper mills, other sectors and municipalities. To solve the water problems of regions lacking fresh water, wastewater treated by advanced oxidation processes (AOPs) can substitute fresh water in highly water-consuming industries. Results of this study have shown that paper strength properties are not impaired and whiteness is slightly impaired only when reusing paper mill wastewater. Furthermore, organic trace compounds are becoming an issue in the German paper industry. The results of this study have shown that AOPs are capable of improving wastewater quality by reducing organic load, colour and organic trace compounds.
臭氧（O3）已成功应用于造纸厂、其他行业和市政废水的深度处理。为了解决淡水匮乏地区的用水问题，经高级氧化工艺（AOPs）处理的废水可替代高耗水行业的新鲜水。本研究结果表明，仅当重复使用造纸厂废水时，才会对纸张强度性能产生轻微影响，而白度则略有下降。此外，有机痕量化合物在德国造纸行业也成为一个问题。本研究结果表明，AOPs 能够通过降低有机负荷、色度和有机痕量化合物来改善废水水质。
