摘要
为维护和改善湖水、水库等大型蓄水设施的水质而寻找一种新的方法,在人工的明/暗光照射条件下,探讨了运用粉末状TiO2作为光触媒,抑制各种淡水藻类增殖的效果。粉末状的TiO2,在100mg/L的浓度下,对蓝藻的铜绿微囊藻原变种、鱼腥藻和绿藻的空星藻有明显的抑制增殖的效果;而对硅藻的钝脆杆藻,在此条件下则没有效果。
In order to develop a new method of water quality improvement in lakes or reservoirs using natural energy, the inhibition of freshwater algal growth was investigated using powdered TiO2 as a photocatalyst under artificial sunlight irradiation with a combination of fluorescent lamp and black light.The growth ofMicrocystis aeruginoso, A nabaenasolitalia and Coelastrum astroideum was effectively inhibited by using powdered TiO2 photocatalyst at a concentration of 100 mg/L, whereas that of Fragilaria cap ucina wasn＇t.
