| 摘 要： | 该文概述了太阳能-二氧化钛(TiO2)光催化水处理技术在生活饮用水净化、消毒和废水处理方面的研究与应用动态。该技术的优点是，TiO2光催化剂在近紫外线区吸光系数大、光催化作用持久、化学性质稳定、对人和环境无害；TiO2在光催化过程中生成的氧化剂具有很强的氧化能力，可使水中大部分微生物灭活和有机污染物分解。该技术由于无须消耗电能，在农村和偏远地区具有很大的实用价值。

| Abstract: | The recent developments in purification and disinfect of drinking water as well as wastewater treatment adopting solar energy-titanium dioxide(TiO2)catalytic technology are introduced in general in the present review. The advantages of this technology are titanium dioxide catalytic agent with strong sunlight absorption in near ultraviolet ray range, lasting catalytic reaction, chemical stable and innocent for human and environment. The oxidizer produced during ray catalytic has strong oxide action that can kill most microorganisms and decompose most organic pollutants. This technology has widespread practical value in the remote areas and rural areas because it does not consume electric energy |
