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.
