Experimental Study on Continuous Degradation of Simulated Wastewater Containing Complex Black WAN with Nano TiO2 Photocatalyst Prepared at Low Temperature

Nano TiO2 photocatalyst has been prepared by the two-step microwave-assisted process at low temperature. The characterization results reveal that the product is titanium dioxide with a pure anatase crystal structure, and has a large specific surface area. In addition, a small size circulated photocatalytic reactor has been designed and developed. This paper investigates the activity of the above-mentioned photocatalyst by the orthogonal experiment on the degradation of simulated wastewater containing complex black, and studies the operation process of the self-made reactor.
