To study the performance of photocatalystic reactor, we designed and made the experiment rig that is fit for sewage treatment. Considering practical applications, we have discussed the optimum inclination for flat photocatalystic reactor. Under the condition of lack solar radiation fact survey date founded on wave band, the suggestions to determine the optimum inclinations for flat solar collector are given. In the experiments of degradation of dye, Congo red and Methylene blue dyes were taken as targets' contamination.
