臭氧深度处理及预处理的应用摘要：随着社会的发展，如今水处理的难度大大升高，水中难降解的物质日渐增多，需要臭氧处理工艺的水厂越来越多，在印染废水中存在有大量亚甲基蓝、甲基橙、罗丹明 B、耐酸大红等，这些染料的分子结构中一般带有苯环、共轭结构等难分解的致癌物质，采用臭氧-混凝组合工艺对印染废水进行深度处理，利用臭氧氧化去除水中的有机物，同时改善混凝沉淀效果，加强混凝沉淀去除 TP 和部分有机物的能力。
同时在饮水长的预处理中依然需要臭氧发挥巨大的效能，近年来，世界范围内多个国家和地区饮用水水源地中出现了由水体富营养化引起的蓝藻水华现象，不仅会引起水体浊度、色度等指标的显著升高，更为严重的是，藻细胞在代谢过程中会产生藻毒素和嗅味物质如二甲基异莰醇（２－ＭＩＢ）、土臭素（ＧＳＭ）等，严重威胁着饮用水安全。
利用臭氧预氧化强化混凝去除水体中的藻细胞，通过控制氧化的程度避免藻细胞大量破损释放胞内２－ＭＩＢ；针对残留在水体中的嗅味物质（２－ＭＩＢ），采用臭氧／过氧化氢深度处理工艺去除。
关键词:臭氧；深度处理； 预处理；Application of ozone advanced treatment and pretreatmentAbstract: With the development of society, the difficulty of water treatment is greatly increased, the substances that are difficult to degrade in water are increasing, and there are more and more water plants that need ozone treatment process. There are a large number of methylene blue, methyl orange, Rhodamine B, acid resistant red, etc. in the printing and dyeing wastewater. The molecular structure of these dyes generally contains carcinogens that are difficult to decompose such as benzene ring and conjugate structure.The combined ozone coagulation process is used for the advanced treatment of printing and dyeing wastewater. The organic matter in the water is removed by ozone oxidation. At the same time, the coagulation sedimentation effect is improved and the ability of coagulation sedimentation to remove TP and some organic matter is strengthened.At the same time, ozone is still play a great role in the long-term pretreatment of drinking water. In recent years, cyanobacteria bloom caused by water eutrophication has appeared in drinking water sources in many countries and regions around the world, which will not only cause a significant increase in water turbidity, chromaticity and other indicators, but more seriously, Algal cells will produce algal toxins and odor substances in the process of metabolism, such as dimethyl isocamphenol (2-MIB) and earth odor (GSM), which seriously threaten the safety of drinking water. The algae cells in water were removed by ozone pre oxidation and enhanced coagulation. By controlling the degree of oxidation, a large number of damage of algae cells and the release of intracellular 2-MIB were avoided; Ozone / hydrogen peroxide advanced treatment process was used to remove the residual odor substances (2-MIB) in water.Keywards: Ozone; Advanced treatment; Pretreatment1.臭氧处理所适用水体当前形式下，我国发展观念改变，绿色的发展观念成为主流，水体污染成为亟待解决，在众多水处理实例中，工业废水，印染废水，含盐废水，石油厂废水，垃圾渗滤液成为热门研究课题，在上述水体中存在大量有毒和难降解物质，对其的处理已经刻不容缓。
催化臭氧技术是建立在臭氧的强氧化性基础上，并在催化剂的吸附、催化特性的联合作用下，深度解决有机物无法达到完全降解的问题，从而有效改善目前废水矿化率和臭氧利用率不高的问题，在目前的废水深度处理及水厂预处理研究方面， 催化臭氧技术作为一个重要的研究支线，在废水处理方面，具有重要的作用。
1.1利用臭氧对水体处理的效果1.1.1印染废水化学纤维织物的发展和染整技术的进步，促使一些新型助剂和浆料被大量投入使用，这导致印染废水中有机污染物浓度不断增加，成分变得更加复杂，从而抑制了传统生化处理方法对有机污染物的降解能力，使得处理后的废水仍具有较高的色度和 COD 值[14]，采用臭氧氧化-混凝沉淀耦合工艺对印染厂二沉池出水进行深度处理，通过优化系统运行参数。
考察了该组合工艺对印染废水的降解效果。
结果表明：在反应时间为 30 min、臭氧浓度为 45 mg/L 的条件下，臭氧氧化效能达到最高，COD 去除率为 24.5 %；通过与混凝沉淀组合，COD 和 TP 的去除率为 50.1 %和 78.4 %[1]。
1.1.2含盐废水我国是世界上最大的糖精钠生产国和出口国， 同时也是糖精钠生产废水排放量最大的国家。
