The utility model has the advantages that：
1. collaboration is handled, raising efficiency：
Two methods of present invention comprehensive utilization plasma body cooperative light-catalyzed reaction, improve system degradation efficiency；
2. ozone of degrading, increases active group：
The present invention can make full use of accessory substance ozone, be produced newly by the reaction between photodissociation ozone and hydrone
OH free radicals, can so produce more OH free radicals, and these free radicals can pass through additional UV spokes after discharge process
Lighting system reacts with contaminant molecule, meanwhile, harmfulness ozone can be removed from discharge gas；
3. comprehensively utilizing energy, energy consumption is reduced：
The present invention application UV light irradiation dielectric surfaces after, except can by some gaseous contaminants (such as ozone) of photodissociation,
Increase outside free radical, UV light can also be with waste gas and H2O molecules direct collision (photooxidation), so as to increase the quantity of micro discharge；
During plasma gas discharge, some high energy excited particles can also give off ultraviolet light, excite photocatalysis
Agent, the degraded to VOCs is played a part of further promoting, based on factors above so that the energy expenditure in total system is reduced；
4. surface treatment, self-cleaning cleaning：
Specially treated is carried out on the block media surface of plasma reaction unit, self-cleaning surface is formed, gas is reduced molten
The deposition pollution of glue and other materials；
5. collaboration is handled, cost is reduced：
The manufacturing cost and O＆M cost of photocatalysis equipment are all well below plasma apparatus, and both make it at Combined Treatment
Cost is greatly reduced, and saves user's fund, substantially reduces its market access threshold.
Certainly, implement any product of the present utility model to it is not absolutely required to while reaching all the above advantage.
