臭氧在水处理中的制约因素及缓解措施

臭氧作为一种强氧化剂 ,在水处理中的应用日益广泛 .随着对臭氧技术的不断探索和应用 ,也发现了其应用过程中的一些抑制因素 .根据臭氧在水中的反应动力学原理和水质情况 ,在给水处理中产生的副产物可用臭氧与活性炭联用或适当加入氨氮的方法加以缓解 ;对循环冷却水中的腐蚀问题要注意臭氧停留时间和加入金属阻蚀剂 ;在废水处理中可选用不同的联用技术来提高臭氧的效能

Ozone''''s retardancy in water treatment and its relieving measures

Ozone, as a strong oxidizer, is more and more commonly used in water_treatment. moreover, with the development and exploration in the ozone_oxidating technique, ozone's retaudancy has been found. In accordance with the relative principles of dynamics and specific water conditions, the by_products in water supply treatment would be moderated by integrating ozone and activated carbon or by adding ammonia nitrogen. As for the corrosion in circulating cooling water system, we must be aware of the duration time of ozone in the water and add some metallic antiseptic.Integrated techniques used in waste water treatment could improve ozone's utility.
