This study focused on the advanced proecess for water purification that utilizes high frequency electromagnetic waves(microwave energy). Exploratory experiments have found that this microwave treatment can decompose the hazardous compounds in the wastewater. The microwave treatment consists of adsorption step passing column and destruction step by microwave energy at a time. During the wastewater passed the microwave reaction column, packed adsorbents, the hazadous compounds were adsorbed onto the pores of adsorbents and microwave energy releases the adsorbed compounds in gaseous form.
