摘要
Abstract
Vitamin C production wastewater was treated by catalytic ozone oxidation process. The effects of the process conditions on the removal of wastewater COD, chroma and Ca2+ were studied. Under the optimum process conditions of using TiO2(20% of mass fraction)-SiO2(80% of mass fraction) as catalyst, reaction temperature 75 t and hydraulic retention time 30 min, the COD, chroma andp(Ca2+) of the effluent are 63.9 mg/L, 0 time and 49.4 mg/L with 78%, 100% and 95% of removal rates respectively. The effluent quality can meet the national discharge standards of GB8986-1996.关键词
