摘要:
紫外线（UV）技术广泛应用于我国市政污水消毒，能有效阻断各类致病微生物向环境转移，保障人类和环境的健康，其运行可靠性是重中之重。作为一种物理消毒技术，紫外线消毒的原理、影响因素和监测维护方法与传统化学消毒方法均不相同。因此，介绍了市政污水UV消毒系统中辐射剂量的概念、影响因素和监测方法，系统探讨了UV灯输出、套管结垢、水UV透过率、流量四个主要影响因素的作用机制，并提出准确的监测和维护方法，以期为UV消毒系统可靠性保障提供理论和技术支持。
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.
