Disclosed is a system for integrally treating a composite waste gas including nitrogen oxides (NOand NO), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and perfluorinated compounds (PFCs). The system includes a first wet processor configured to wash and adsorb dust including gases, SO, and ash dissolved in water, a decomposing reactor configured to receive waste gas processed in the first wet processor and process nitrogen oxides (NOand NO), fluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and perfluorinated compounds (PFCs) in the waste gas, and a second wet processor configured to receive the waste gas processed in the decomposing reactor and wash and adsorb the received waste gas. The system can efficiently treat a large amount of composite waste gas.

Provided an air cleaning system, which includes: a first reactor which has a first inlet and a first outlet and in which a channel is formed; a first moisture adsorption filter and a first water-soluble gas pollutant adsorption filter that are provided inside the first reactor and are provided so that a gas passes therethrough sequentially while flowing along the channel from the first inlet to the first outlet; a plurality of first magnetrons that are provided at a lateral portion of the first reactor so as to correspond respectively to the first moisture adsorption filter and the first water-soluble gas pollutant adsorption filter and selectively apply microwaves to the first moisture adsorption filter and the first water-soluble gas pollutant adsorption filter; and a heat exchanger that receives hot air containing a water-soluble gas pollutant and moisture, both of which are desorbed from the first moisture adsorption filter and the first water-soluble gas pollutant adsorption filter and are discharged by the first outlet, condenses the moisture into water, and dissolves and discharges the water-soluble gas pollutant in the condensed water. According to the present invention, the air cleaning system can unify a dehumidifying process and a water-soluble gas pollutant removing process to simplify an air cleaning process, recover and recycle waste heat by introducing microwaves and the heat exchanger so as to contribute to energy saving, and be used semi-permanently without a need to periodically replace a filter.

An adsorbent having a microwave absorption property is provided. The adsorbent having an improved microwave absorption property, which has a core-shell structure including a silicon carbide bead disposed therein, and an adsorbing material disposed outside the silicon carbide bead, can be provided. Also, the adsorbent may further include a plurality of silicon carbide particles dispersed and disposed therein and having a diameter of 1 &#x3bc;m to 10 &#x3bc;m, and the adsorbing material may be ion-exchanged with a cation. Therefore, the adsorbent can be useful in improving desorption efficiency since the adsorbent may be rapidly heated by microwaves to reach the desorption temperature due to high reactivity to microwaves. Also, the adsorbent can be useful in maintaining full adsorption capacity without having an influence on adsorption quantity since the silicon carbide bead is disposed in the inner core of the adsorbent. Further, when the adsorbent is applied to conventional systems for removing organic compounds using microwaves or dehumidification systems, the adsorbent can be semi-permanently used, and may also have an effect of enhancing the energy efficiency by 30% or more, compared to adsorbents used in the conventional systems.
