摘要:
目前,紫外光解技术被看作是处理难降解有机物有效方法之一,具有反应条件温和、氧化能力强等优势.传统有极汞灯寿命短、波长单一、光效低的缺点导致其在实际工程中的应用受到局限.而微波无极灯作为一种新型高效光源,具有光氧化活性高、光谱范围选择性大、装置简单等特点,同时实现了微波和紫外辐射的共同作用,又具有微波的选择性加热、操作简单、设备体积小、无热媒和热惯性等优点,大大提高污染物的降解效果.本文对可解决传统紫外辐射技术在环境污染控制工程应用时存在问题的微波无极紫外技术的相关情况做了系统性阐述.介绍了微波作用原理、微波激发无极紫外作用原理以及微波无极紫外光解技术原理;并在此基础上对无极灯在废水、废气及吸附剂再生方面的应用和无极灯技术参数、微波功率、温度、介质特性等影响因素进行总结;在现有研究成果基础上展望了微波无极紫外辐射的应用前景和需要进一步解决的问题.

Abstract:
Currently, UV photolysis technology is seen as an effective method to deal with refractory organic matter or other pollutants because of its mild reaction conditions, strong oxidizing capacity, and other advantages. The shortcomings of the traditional mercury lamps, such as short lifetime, single wavelength, and low luminous efficiency, have limited their application in practical engineering. Microwave electrodeless lamp is a new type of high efficiency light source. It has the characteristics of high photooxidation activity, large spectral range selectivity, and simple device. At the same time, microwave and ultraviolet radiation are combined to greatly enhance the degradation of pollutants. Besides, microwave has the advantages of fast heating, small space occupation, no variation in light intensity, no heat medium and thermal inertia. Firstly, the principle of microwave and microwave-assisted photooxidation were introduced. Secondly, the principle of luminescence of microwave electrodeless lamp was also introduced. The application of electrodeless lamp in the treatment of water and gas and its regeneration of adsorbent were explored. At the same time, its influence factors were summarized, including electrodeless lamp, microwave power, temperature, and dielectric properties. Moreover, suggestions for further studies were also put forward.
Key words:  microwave  electrodeless lamp  UV  photo oxidative degradation  organic pollutants
