紫外发光二极管在水产养殖杀菌消毒中的应用与展望

紫外发光二极管(UV-LED,200~400 nm)半导体固态光源具有节能环保、快速开启、体积轻便等特点。随着UV-LED性能的不断提升,未来有望取代传统的紫外汞光源。介绍了紫外发光二极管UVC段(UVCLED,200~280 nm)技术的发展状况、存在的问题及技术提升的路线,比较了国内外UVC-LED水产领域研究成果,并基于水产养殖业微生物病害种类,给出了杀灭有害微生物所需要剂量的计算方法和UVC-LED在水产业微环境实际应用的设计建议;对未来UVC-LED达到大规模应用杀菌消毒的发展趋势做了展望,以期对水产养殖业绿色持续发展有所帮助。

Application and prospect of UVC-LED in aquaculture sterilization

Ultraviolet light-emitting diode(UV-LED,200-400 nm)semiconductor solid-state light source is energy saving,environmentally friendly,easy to operate and small in volume.With the continuous improvement of UV-LED performance,it is expected to replace the traditional UVC-band LED mercury light source in the future.This paper first introduces the development of ultraviolet(UVC-LED,200-280 nm)technology,the existing problems and the route for technical improvement,and compares the research results of UVC in aquaculture industry at home and abroad.Then,based on the species of microbial diseases in aquaculture,the calculating method of the dose needed to inactivate harmful microbes and the design suggestion for actual application of UVC-LED in aquacultural microenvironment are given.Finally,the trend of UVC-LED to achieve large-scale application of sterilization is prospected,so as to help the sustainable development of aquaculture.
