中文摘要 | 本研究係利用固定化的樹脂觸媒去除染料廢液的色度。固定化的樹脂觸媒有效的 去除染料廢液中的 ADMI 值(真色度),研究中發現利用濃度為 0.5M 的氯化鐵含浸劑所製 備之樹脂觸媒,再配合 0.1M 的過氧化氫反應溫度為 80 ℃,其去色效果高達 95 %以上。 本研究中樹脂觸媒反應效率與反應廢水及樹脂觸媒比例有關,樹脂觸媒用量與氧化反應效率 成正比之關係。本研究並探討反應條件之變化對於氧化效率之關係,如反應時間,反應溫度 ,樹脂觸媒與廢水之比例,反應之 pH 等。實驗得知廢水與樹脂觸媒比例為 200ml/lg 時, 染料之去色效率超過九成僅需要反應1小時, 而廢水與樹酯觸媒比例為 200ml/10g 時只需 反應10分鐘,樹脂觸媒使用量越多其去色的時間越短。當反應時間達1小時以高用量的去 色效果最佳,可達9成8的去色能力。本研究經實驗證實當其反應到達1小時,其去色效果 會達一平衡值,反應去色率之變動性不大。 |
英文摘要 | The decolorization of dye wastewater was achieved by using the heterogeneous catalyst oxidation process. The high performance heterogeneous catalysts were prepared by ionic exchange resin with ironic ion. In this study, the color removal was higher than 95% in 40mintues with 0.1M H �� O �� and 1g catalyst resin at 80 ℃. The results showed that the efficiency of oxidation reaction and decolorization rate of wastewater was strongly dependent on the ratio of volume of wastewater to amount of catalyst. In this investigation the dominated factor of oxidation reaction, such as reaction time, reaction temperature, pollutant concentration, pH e.g., were discussed the relationship between the reaction condition and decolorization rate. In this study, the decolorization rate strongly dependent on the rate of volume of wastewater to amount of catalyst. For example, the decolorization was over 95% in one hour with 200 ml/lg wastewater to catalyst ratio and the decolorixation was over 95 in 10 minutes with 200 ml/lg wastewater to catalyst ratio. It was evidenced that the high catalyst loading induced a higher decolorization rate in catalyst oxidation process. |
