개전료채용TiO2위광최화제、자외등광원,대초화폐수진행광최화강해적연구,주요탐토료광조반응시간、TiO2투가량、용액 pH 치등인소대초화폐수TOC거제솔적영향,병대광최화양화궤리진행탐토。결과표명：TiO2광최화양화대초화폐수TOC거제효과명현,재광조반응시간3.5 h,TiO2투가량4.0 g/L,용액 pH 치위6.3,TOC거제솔초과49%。
TiO2 as photocatalyst and UV light source was used to conduct the photocata-lytic degradation for coking wastewater.The effects of irradiation reaction time,TiO2 dosage and initial pH in solution on TOC removal rate of wastewater were investigated, and the mechanism of photocatalyst was also discussed.The results showed that photo-catalytic oxidation process was effective for the TOC removal of coking wastewater,and TOC removal rate could reach more than 49 % under the conditions of irradiation time 3.5 h,TiO2 dosage 4.0 g/L,and initial pH 6.3.
