The paper investigated the feasibility of photocatalytic degradation of organic pollutants in landfill leachate with solid-phase TiO₂ film.researching the influence factors of preparing the TiO₂ film and photocatalytic degradation activationt,he optimum annealed temperature is 450℃.It is investigated that some factors such as.the irradiation timei、nitial pH of solution、 initial concentration of solutions and light intensity infuluence the photocatalytic degradation rate of landfill leachate.The study showed the photocatalytic degradation rate increases with the increasing of the irradiation time and decreases with the increasing of the initial concentration,the condition of acidity and alkalescence are propitious to the action.On the optimal condition,the optimum annealed temperature is 450℃,initial pH of solution is 3～4,initial concentration of solution is 537 mg·L^-1,the irradiation time is 2h,the degradation of COD_Cr and UV335 are 94.4% and 96.9%.
