摘要
介绍了纳米TiO2的光催化机理,讨论了其在废水处理中的不足之处以及近年来的改进手段。概述了光催化技术在处理含油废水、含药废水、印染废水、造纸废水、表面活性剂废水、重金属污染物废水等方面的最新应用研究进展,指出了其在废水处理中还存在阳光效率低、回收再利用困难、降解效率有限等问题及今后的研究趋势。
Photocatalytic mechanism of nanometer TiO2 and its disadvantages in wastewater treatment as well as improvement methods in recent years were discussed. The latest application of nanometer TiO2 photoeatalytie technology to the degradation of pesticide wastewater dyeing and printing waste waters, papermaking waste water and wastewater with surfactant, petroleum, heavy metals were reviewed. At last efficiency of sunlight, difficulties in recycles, and limits in existing problems were pointed out, such as low utilization removal efficiency, as well as further study trends.
