中文摘要 | 三氯乙烯(TCE)及四氯乙烯(PCE)等有機氯污染物,不論在台灣或美國都是除污重點。目前,活性炭吸附法、氣提法是較經濟有效的方式,但僅能將污染物由水源移除,無法達到真正降解的目的。利用輻射配合氧化劑,如臭氧或二氧化鈦去除有機氯污染物,清除率最為理想。TCE和PCE經輻射降解後的產物不具毒性。若能適當地加入特定的金屬離子,像鐵離子,使降解效果更好。以目前的數據看來,應用輻射線來實際處理有機氯廢水之發展潛力無窮。 |
英文摘要 | Organic chlorine pollutants such as trichloroethylene (TCE) and perchloroethylene (PCE) are the focal points of waste water that must be treated in Taiwan or America. At present, although activated carbon and air-stripping methods are more economical and efficient, they can only remove the pollutants from water. However, those methods can not decompose them. Irradiation treatment showed efficient removal of TCE and PCE. The reviewed articles showed the best removal by utilizing irradiation cooperating with the oxidant like ozone (O3) and titanium dioxide (TiO2). The decomposition products of TCE and PCE showed no cytotoxicity. When we added some specific metallic ions like the iron ion to water, it brought a more effective decomposition. According to the present data, there will be a huge potential for the development of using irradiation on treating waste water containing organic chlorine practically. |
