In this paper, the orthogonal experiment method was used to study technological conditions for photocatalytic degradation of dye printing wastewater which selecting the anatase TiO 2 as photocatalyst and high-pressure mercury lamp as light source. The experimental results showed that the optimized conditions were determined as follows:the amount of TiO 2 was 6 g·L -1 , pH value was 5.35, the time of 300 W UV illumination was 120 min and the amount of air was 1.5 L·min -1 . Under the conditions, the removal efficiency of COD Cr and color of dye printing wastewater could reach 85.60% and upwards 98.0% respectively.
