Inactivation of algae by photocatalytic reactor using immobilized TiO onto nickel foam
固载型TiO光催化反应器对富营养水体杀藻作用研究

With nickel foam as a carrier,TiO2 was loaded on nickel foam by electrodeposition and a TiO2 photocatalytic reactor was made. The study shows that by the photocatalytic reactor chla in eutrophic water dropped from 96.2 mg/m^3 to 2.2 mg/m^3 ,decreasing 97.6% in 30 hours,while under the same intensity of UV radiation,the decline rate of chla was only 79.5% in the ordinary nickel without load TiO2 reactor. The results showed that nanophotocatalytic material was the important reasons for killing algae. A 9.54 m^3 spray pool was used for the algae-killing test, the result showed the photocatalytic reactor killed algae and exhibited excellent performance,chla dropped from 18.7 mg/m^3 to 1.9 mg/m^3 ,decreasing 89.8% in 12 days. The performance of the photocatalytic reactor indicates that it has a very strong capacity to kill algae. The reactor has a great significance in effectively killing algae in eutrophic waters, controlling algae base, emergently treating eutrophic urban landscape water and lake water, and improving urban water environment.
