Ultraviolet light (UV) has the advantages of broad-spectrum disinfection, high efficiency, no disinfection by-products, etc. It has been widely used in the disinfection of drinking water, municipal sewage, reclaimed water and ship ballast water. The overall disinfection effect of the UV disinfection system is highly dependent on the actual (effective) radiation dose of the UV. Accurately obtaining the intensity distribution of UV in the UV disinfection system is of great significance for calculating the disinfection dose and ensuring the disinfection effect, and can also guide the optimization and modification of the internal structure of the disinfection system. However, it is currently impossible to accurately measure the UV intensity distribution in the UV sterilizer under actual operating conditions.
The National Key Laboratory of Environmental Water Quality of the Chinese Academy of Sciences Research Center for Environmental Water Quality has recently developed a novel in-situ fluorescence microprobe with good stability, fast response (10-6s) and small volume (0.07 cubic meters). Mm) and other obvious advantages, its temperature coefficient, nonlinear and other detection performance is greatly improved compared to conventional chemical sensitometers. The in-situ fluorescence microprobe has a characteristic of approximately 360-degree response, which can well simulate the effect of ultraviolet radiation on pathogenic bacteria in water.
On this basis, the researchers developed a test platform that can test the UV intensity distribution in the tube-type UV sterilizer cavity. The main components include fluorescent micro-probes, high-precision guide rails, temperature control devices, sterilizer fixtures, error correction devices, The data automatic recorder and the ultraviolet transmittance (UVT) monitoring device can realize the in-situ on-line rapid test of UV intensity distribution under different UVT water bodies and different water temperatures, and the standard deviation is 0.04 mW/cm2 (0.3%). Recently, the research results have been published in the environmental field journal Environmental Science & Technology (2011, 45 (7), 3034-3039), and in May 2011, the "World UV and Ozone Conference" (Joint IOA-IUVA World) Reports were made by Congress, Paris, and scholars and engineers from all over the world showed great interest in this achievement and conducted extensive exchanges.
International authoritative scholars in the field of UV disinfection visited the experimental device, fully affirmed its innovation and application prospects, and hoped to use the accurate testing of the platform to conduct collaborative research in various aspects in the future. The research results are expected to be realized: 1) verifying the mathematical models of several existing UV intensity distribution calculations in the world to correct the model; 2) the internal structure of the disinfection system (such as the inlet and outlet setting mode, the arrangement of the lamps, The inner wall reflective material, etc.) is improved to improve the disinfection efficiency; 3) the actual UV dose of various ultraviolet sterilizers is evaluated and verified by a computational fluid dynamics (CFD) model.
The research team has cooperated with Anlis Technology Development Co., Ltd. and Zhengzhou Water Technology Development Co., Ltd. to systematically distribute the UV intensity of the single-tube and multi-lamp tube sterilizers for drinking water disinfection. Test and greatly improve the disinfection effect by optimizing the structure of the disinfection device. The research team is currently committed to continue to optimize and promote the application of the test platform to form a fast, economical, high-precision UV disinfection disinfection evaluation and verification method with independent intellectual property rights, standardization and standardization of the ultraviolet disinfection market, and guarantee disinfection. Security provides strong technical support.
