摘　　要：通过对金属组份与载体影响及催化剂制备方法等因素的考察，研制出性能优良的催化湿式氧化催化剂，用于治理焦化厂蒸氨、脱酚前的含ＣＯＤｃｒ６３０５ｍｇ／Ｌ及ＮＨ３－Ｎ３７７５ｍｇ／Ｌ的高浓度焦化废水。在２８０℃，８．０ＭＰａ，液体空速＝１．０ｈ－１条件下，对ＣＯＤ及ＮＨ３－Ｎ的去除率分别为９９．５％及９９．９％。通过１０００ｈ催化剂寿命考察试验，确定催化剂稳定性良好，能够在水热条件下抗酸、碱腐蚀，长期使用。此外，该催化剂在处理高ＣＯＤ的染料、印染等废水中也有很好的效果。A new kind of catalyst containig Ruthenium, rare earth metal and Titania and with high oxidative activity was prepared by some special techniques and the results for treatment of coke oven wastewater showed that under the conditions of temperature of 280℃ and pressure of 8.0MPa, the decomposition rates of COD Cr and NH 3-N are 99.5% and 99.9% respectively. The satisfied results were also obtained in the treatment of wastewater from dye and dye printing industry by this kind of catalyst.
