Abstract: Photocatalytic treatment of emulsified waste liquid after pre-treatment is carried out, using TiO2 as catalyst. The influence of crystal structure, particle size, amount of the catalyst and initial pH value on the removal ratio of the chemical oxygen demand (COD) is studied in this essay. The results show that in the conditions that 0.5% quality point, P25-1 photocatalyst, 6.5 pH value and 90 min processing, the treatment effect is most ideal.
