Abstract: Nano TiO2/attapulgite have been prepared for photocatalyst treatment NH3-N wastewater. The photocatalyst of preparation methods and conditions have been studied. Through orthogonal experiment, the best conditions of catalyst dosage, calcination temperature and illumination time have been ascertain. The photo catalyst process NH3-N wastewater, the degeneration rate reaches 84%.
Key words: nano TiO2; attapulgite; NH3-N wastewater
