摘要：

乳化液废水的均相催化湿式氧化实验发现，单一金属盐催化活性：Cu（NO₃）2>MnSO₄CoCl₂。考察了不同反应条件（温度、氧分压、进水有机物浓度）对铜盐均相催化湿式氧化的影响，结果表明，该工艺在200℃活性最高，在进水COD 48 400mg/L，反应2 h时，COD去除率为86.6%；供氧量以初始氧分压0.93~1.16 MPa（25℃）为宜；该工艺在较宽进水浓度范围内有较高的去除率。

Abstract:

According to the experimental results of homogenous catalytic oxidation of Cu salts of emulsification wastewater, it is found that the catalytic activity of single-metallic salts accords with: Cu(NO₃)₂ >MnSO₄ >CoCl₂.The Cu salts exhibite the most effective activity is obtained at 200 ℃, COD removal rate 86.6% (inlet water COD_Cr:48400mg/L)after oxidation 2 h. It is fitting when fractional pressure of oxygen is 0.93~1.16 MPa (25℃);CWAO has a good performance in a wide range of inlet wastewater concentration.

Key words: emulsification wastewater, catalytic wet air oxidation, homogenous catalysis
