光催化膜反应器用于亚甲基蓝的降解

DEGRADATION OF METHYLENE BLUE USING PHOTOCATALYTIC MEMBRANE REACTOR

研究了催化剂颗粒粒径对降解速率的影响，并将光催化反应和膜分离技术相结合，开发了光催化膜反应器。利用该反应器对亚甲基蓝进行降解的结果表明，亚甲基蓝可被很快地降解，而悬浮在反应液里的催化剂颗粒同时可被有效地分离回收并连续地在反应器里使用。

Effects of particle size of photocatalyst on the degradation of methylene blue were studied. Results indicated that the reaction rate of degradation would increase with the decrease of particle size of photocatalyst. A photocatalytic membrane reactor, which combined inorganic membrane separation technology and photocatalytic reaction, for treating wastewater containing organic compounds was designed. Methylene blue was degraded using the reactor. Results indicated that methylene blue could be degraded efficiently, and the photocatalyst,which were suspended in an aqueous solution, could be separated for reuse.
