| 摘 要： | 采用「Ｃｕ－γ－Ａｌ２Ｏ３」催化剂对由活性艳红Ｘ－３Ｂ配制的ＣＯＤｃｒ为５７００ｍｇ／Ｌ色度３１００倍的实际染料废水进行了催化氧化试验，试验表明，在控制ｐＨ＝４－５，Ｈ２Ｏ２用量为５．０ｍｇ／Ｌ，催化剂用量为３．０ｇ／Ｌ，ｔ＝７０℃和反应时间为２ｈ条件下，可获得ＣＯＤｃｒ去除率为７７％－７８％，脱色率为９９％的良好效果，且催化剂可再生使用。

| Abstract: | Treatment on active red X-3B solution and actual wastewater of COD 5700mg/L and chroma 3100 times with catalyst Cu- y -A12O3] has been conducted. The results showed that the removal rates of COD and color were 77% ~ 78% and 99% respectively under the conditions of t=70C, pH = 4~5, H2O2 dosage 5.0mg/L, catalyst dosage 3.0g/L and reaction time 2hr, which provided a new catalyst and new ways for treating wastewater. |
