摘要
研究以纳米TiO2为基本活性组分、高炉水渣为载体、以太阳能中的紫外光代替紫外灯，激发纳米TiO2产生·OH自由基，将富营养化水体中的藻类光催化氧化去除。考察了焙烧温度、投加量、光催化时间、pH值、重复利用、实际使用等对纳米TiO2杀藻效果的影响。
The removal of algae in eutrophic water body by OH was studied. We took TiO2 as active material, blast furnace granulated slag as carrier, then irradiated with sunshine to inspire OH. And also, we detected the influencing factors on algae- killing, such as calcination temperature, adding dose, Photocatalytic time, pH, reuse, real use etc.
