摘要:
臭氧作为一种强氧化剂，在水处理中得到了广泛的应用，有明显的杀菌消毒作用，同时臭氧又有较强的助凝作用，能够促进气浮工艺的处理效果，气浮分离由于不但可以明显的降低水中的悬浮物，而且COD也可得到一定的去除。臭氧–气浮工艺则结合二者优点，将臭氧氧化技术与气浮分离技术相结合，采用臭氧化空气为气源，去除悬浮颗粒物同时又分解大量有机物，且有明显的杀菌消毒作用，在一个操作单元内实现了破乳或絮凝、固液分离、除色、嗅、昧、消毒等多个过程。
Abstract: As a strong oxidant, Ozone which was widely used in wastewater treatment played an important role in dis-infection and coagulation aid to promote the flotation separation effect in the flotation process. Flotation can signifi-cantly reduce the suspended solids in water, and COD can be removed in a certain degree. The ozone followed a flota-tion process is a combination of the two advantages. The combination of ozone oxidation and flotation separation tech-niques can use ozone as gas source, and remove suspended particles while decomposition of large amounts of organic disinfection. As a result, it can get emulsion breaking and flocculation, solid-liquid separation, decolorization, deodorant, disinfection and other process in one operating unit.
