    摘要: 本研究目的為利用活性碳觸媒氧化法處理豐生製藥公司之廢水,以硫酸銅或硫酸亞鐵活化椰殼,製備成高孔隙活性碳觸媒並應用於製藥廢水之觸媒氧化處理,比較廢水pH值、過氧化氫濃度與反應溫度對製藥廢水COD 去除效果之影響。結果顯示,以硫酸亞鐵活化所製備出之活性碳具有良好之氧化效率,COD 為3000mg / L 之製藥廢水於適當反應條件「約有90%之COD 轉化率;而以硫酸銅活化所製備出之活性碳則約僅有30 %之COD 轉化率。比較各反應條件下之氧化效率,結果顯示,氧化程序中活性碳媒之金屬種類。製藥廢水之pH 值、過氧化氫濃度與反應溫度會顯著影響製藥廢水之處理效率。
    The purpose of this investigation is to prepare the porous activated carbon catalyst for pharmaceutical wastewater treatment with discarded coconut shells by using the copper sulfate or iron sulfate as the chemical activation agent The influent factors on the COD removal of pharmaceutical wastewater in oxidation were considered by wastewater pH, dosage of H2O2 and reaction temperature. The active metal ions on catalysts strongly affect the pore properties and surface area of activated carbon. Superior performance of the FeAC catalyst activated by iron sulfate can be obtained with pharmaceutical wastewater at COD concentration of 3000 mg/L, while the lower COD abatement efficiency was found in CuAC catalytic oxidation process. The efficiency of oxidation was mainly limited by the initial pH values of pharmaceutical wastewater, the oxidant concentration and reaction temperature. Increase of the oxidant dosage and the optimal pH and higher reaction temperature could increase the COD removal efficiency of pharmaceutical wastewater. It was concluded that metal type on the catalyst surface, the oxidant concentration, initial pH of pharmaceutical wastewater and reaction temperature played the important roles in the oxidation system
