摘要

The present invention relates to a process for improving the treatment efficiency of hexavalent chromium and a method for simultaneously removing hexavalent chromium and an environmental hormone using a water treatment apparatus in which a nanotubular photocatalyst immobilized on a sunlight-irradiated titanium support is rotated, In the reduction reaction, the photocatalyst is reacted with the bisphenol A, which is a substance, to retard the recombination of electrons and holes in the photocatalyst, The present invention aims to provide a method for improving the treatment efficiency of hexavalent chrome and simultaneous removal of hexavalent chromium and environmental hormone by using a water treatment apparatus in which the immobilized nanotube type photocatalyst rotates by itself. For this purpose, a nanotube type photocatalyst immobilized on a titanium support is irradiated to a reactor using a self-rotating water treatment apparatus, and an artificial light source and sunlight are irradiated to the reactor, and the surface characteristics of the photocatalyst and the water- , Hexavalent chromium and bisphenol A can be effectively reduced and oxidized. In particular, it is possible to treat pollutants effectively using sunlight existing in nature, and it can be applied to water treatment technology based on renewable energy.
