This paper describes the potential of using gamma radiation technology to degrade trichloroethylene (TCE) and perchloroethylene (PCE) wastewater. The experimental method is divided into two parts: (1) using the gamma-ray to irradiate the TCE and PCE solution, the dose-rate is 10 Gy/minute, the irradiation dosage is 0-2.5 kGy and (2) self-making the UV irradiation system, the tube specification is 254 nm and 6 W, and turning on 8 tubes at the same time to make the irradiation.
The efficiency of degradation ratio for gamma-ray is better than UV in the range of 0.1-250 ppm; for example, as for the concentration of 0.1 ppm, when TCE is degraded to D(90) and T(90). the gamma-ray only needed 46.7 Gy and took about 4.67 minutes, but UV needed to take about 28.1 minutes. The dose-concentration equations of TCE and PCE are: TCE: y = 44.58+8.832x, R(2) = 0.999: and PCE: y = 81.33+12.81x, R(2) = 0.997. We verified that the radiation technology is able to effectively degrade the organic chlorine wastewater without yielding the secondary pollution. and the TCE and PCE that degraded by using gamma-ray will be reached US-EPA and Taiwan Effluent Standard (5 ppb).
