The present situation and future trend of the applications of TiO_2 in the wastewater treatment

摘要

With the improvement of industrial technology level there are more and more special water quality in the waste water, this bring great difficulties to the water treatment, and the water environment has been an unprecedented severe challenges , especially in some industrial cities. This not only endanger the safety of nearby residents drinking water, even threatening the whole ecological environment. There are some people proposed TiO_2 photocatalysis oxidation technology in wastewater treatment may play an important role, so it has been a hot issue in the field of science and technology research.
