摘要
在能源、环境问题日趋严重的今天,污水处理技术越来越受到人们的重视,由于太阳能具有再生能源及绿色能源的优势,污水处理结合太阳能技术有着良好的应用前景。本文详细讨论了光催化剂在太阳光下的反应机理,并以亚甲基蓝为目标降解物,探讨亚甲基蓝在暗处的自然衰减、在日光下的直接降解与以二氧化钛作为催化剂进行太阳能光催化污水处理的降解效果,指出了日光下二氧化钛光催化降解的优点以及需要解决的问题,最后对新型光催化剂ZnWO_4/TiO_2进行了研究。
At present, the energy and environmental problems are becoming more and more serious. Sewage treatment technology is attracting more and more attention. Because solar energy has the advantage of renewable energy and green energy, sewage treatment combined with solar energy technology has a good application prospeet. The reaction mechanism of photocatalyst under sunlight was discnssed in detail. At the same time, the degradation effect of methylene blue as the target was discussed, and the degradation effect of methylene blue on the natural attenuation in the dark area, the direct degradation in sunlight and the photoeatalytic treatment of solar photocatalytic wastewater with titanium dioxide as a catalyst were studied. The advantages and problems of photocatalytic degradation of titanium dioxide under sunlight were pointed out. Finally, a new photocatalyst ZnWO4/TiO2 was studied.
