Application of Ozone Oxidation and Flotation Separation in Wastewater Treatment
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.
