摘　　要：在太阳光的紫外线辐射下，应用载有TiO2薄层的平板式光催化反应器，进行了光催化降解法去除水中罗丹明染料的试验。结果表明，当紫外线辐射强度平均为33W／m2、反应时间为18min时，水中罗丹明染料浓度由10mg／L降至0．1mg／L，达到国家排放标准。探讨了太阳能光催化反应系统的改进方向及工业化应用的有关问题。A series of tests for photocatalytic degradation of Rhodamine dye in a photocatalytic re-actor with a plate coated with TiO, was carried out. The experiment results showed that the con-centration of Rhodamine dye was dropped down from 10 mg/L to 0.01 mg/L under the conditionsof 33 W/m2 of UV radiation strength and 18 min of reaction time, meeting the national dischargestandards. The improvement and industrial application of the sunlight photocatalytic reaction sys-tem were also discussed.
