Abstract:
Ultraviolet (UV) technology can block the propagation of pathogenic microorganisms to the environment and safeguard the health of humans and the environment, which has been widely used for disinfection in municipal wastewater treatment in China. And its operation reliability is the top priority. As a physical disinfection technology, the mechanism, impact factors, monitoring and maintenance methods of UV disinfection are different from those of conventional chemical disinfectants. Therefore, the concept, impact factors and monitoring methods of the fluence of UV disinfection in municipal wastewater treatment was introduced in this paper. The mechanism of the main impact factors, including UV lamp output, sleeve fouling, UV transmittance of water and flow rate, were discussed. Accurate monitoring methods were proposed together with operational maintenance. This work is expected to provide theoretical and technical support for the reliability of the UV disinfection system.
