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>MnSO4>CoCl2。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 48 400 mg/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。According to the experimental results of homogenous catalytic oxidation of wastewater, it is found that the catalytic activity of single-metallic salts accords with： Cu salts of emulsification Cu （NO3）2 〉 MnSO4 〉COCl2. The Cu salts exhibite the most effective activity is obtained at 200℃, COD removal rate 86.6% （inlet water CODCr： 48 400 mg/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.
