1前言臭氧是用物理方法产生的化学消毒剂,具有高效、广谱、无残余污染及应用方便等特点,在环保、食品、化工、医疗卫生等行业已得到广泛应用。臭氧是一种强氧化剂,具有很强的灭菌消毒、除味、去色、降解有机物的特性。应用臭氧进行消毒净化,具有无毒、无害、无任何残留的特点,臭氧被誉为是当前世界上最洁净的消毒剂。水产养殖用水经臭氧处理后,水质状况得到明显改善,水中有毒、有害物质得到有效降解。随着人们对臭氧的深入了解与认识,目前臭氧在水产养殖和育苗的水质净化中应用日趋广泛。在臭氧的应用中原料气的选择,对臭氧系统运行过程的技术经济性能有重要的影响。因此,专题对各种常用气源的基本特性及应用效果进行分析,有助于人们对臭氧的正确与合理应用。 1 Introduction Ozone is a chemical disinfectant produced by physical methods. It has the characteristics of high efficiency, broad spectrum, no residual pollution and convenient application. It has been widely used in the fields of environmental protection, food, chemical industry and medical treatment. Ozone is a strong oxidant, with strong sterilization, odor, color, degradation of organic compounds. Application of ozone for disinfection and purification, with non-toxic, harmless, without any residual features, ozone is hailed as the world’s cleanest disinfectant. Aquaculture water after ozone treatment, water quality has been significantly improved, toxic water, harmful substances are effectively degraded. With people’s deep understanding and understanding of ozone, ozone is widely used in water purification of aquaculture and seedling breeding. The choice of feed gas in the application of ozone has a major impact on the technical and economic performance of the ozone system operation. Therefore, the topic of a variety of commonly used gas source of the basic characteristics and effects of the application analysis, contribute to the correct and rational use of ozone.
