PHOTOCATALYST FOR TREATING WASTE WATER AND PROCESS OF TREATING WASTE WATER USING THE SAID CATALYST

摘要

The present invention provides a process for producing a catalyst for treating wastewater, characterized in that at least one of oxides, carbonates and hydroxides is added to and mixed with titanium dioxide or metatitanic acid, followed by ball milling and then calcining at 550 to 1100 ° C . Also, at least one of oxides, carbonates, and hydroxides is mixed with 0.01 wt% to 5.0 wt% to provide a catalyst for treating wastewater according to the above production method.;The present invention also provides a method for treating wastewater, characterized in that the catalyst produced by the above method is contacted with wastewater while irradiating light having a wavelength of 200-600 nm.
