Abstract

In order to develop a new treatment plant which is easily maintained at low cost, does not cause secondary pollution, and is suitable for an operator of small business like dry-cleaning, photodegradation of tetrachloroethylene (PCE) in the wastewater from dry-cleaning with three types treatment apparatus (45m<i>l</i> Spiral, 270m<i>l</i> Hollow Circular Cylinder, and 3,000m<i>l</i> Circular Cylinder) and test plant (1,200m<i>l</i>) were examined.<br>The degradation rate, the degradation efficiency and the concentration of trichloroethylene (TCE), and the intermediate compounds produced by photodegradation of PCE were investigated under the UV irradiation alone at 185nm and 254nm in the presence (oxygenic condition: Oxyg) and absence (oxygen free condition: OxyF) of dissolved oxygen (DO).<br>Though the difference of the degradation rates of PCE under Oxyg and OxyF was not observed for all of three types, an intermediate TCE product was prevented under OxyF.
