Abstract

|
|
|
The use of photo-catalytic processes in pollution abatement and resource recovery has a significant economic importance. Therefore, the applications of photochemical oxidation of secondary effluent driven by UV, TiO_2, TiO_2/UV, H_2O_2/UV and TiO_2/H_2O_2/UV, have been investigated in order to treat the secondary effluent from municipal sewage. Various experimental parameters such as BOD, CODcr, Nurbidity, total P, and SPC were examined in each photo-catalytic reaction system. The results showed that the application of single oxidant such as UV, TiO_2 only has a minor effect on parameters reduction (CODcr, BOD, etc) to treat the secondary effluent, whereas the combinations of oxidants increase the removal efficiency. The best removal efficiency in every parameters was achieved by the combination of TiO_2, H_2O_2 and UV. It was also found that the optimum amount of TiO_2 for the treatment was 1 g/ℓ to achieve water reuse standard. From the results, the photocatalytic reaction system can be an alternative as a post-treatment to treat the secondary effluent from municipal sewage.
