The simultaneous treatment of H₂S and NH₃ typical odours by plasma was investigated and the co-treatment of both was found to have a facilitating effect the conversion. The degradation efficiency and by-product emissions of single plasma technology and plasma co-catalytic two-stage technology were compared and the degradation mechanism was further analyzed. The results show that in the single plasma technology conversion experiment, the conversion rate of the treated odours mixture is higher than that of the treated single odours, and the by-product emissions of SO₂ and NO_x are also reduced due to the reaction of intermediate products and by-products during the reaction process. The absolute removal of the odours mixture is optimal when treating at a gas flow rate of 6 L/min, a voltage of 16 kV and a frequency of 200 Hz. The M(Ce,Cu)-Mn/13X loaded catalyst was synthesized by co-precipitation method. Under the conditions of gas flow rate of 3–7 L/min, the efficiency of H₂S and NH₃ removal and the reduction of by-product emission were ranked as: uncatalyzed > Cu-Mn/13X > Ce-Mn/13X, which proved that Ce-Mn/13X showed better catalytic activity and application value.

研究了等离子体同时处理H ₂ S和NH ₃典型气味，发现两者的共同处理具有促进转化的效果。比较了单等离子体技术和等离子体共催化两级技术的降解效率和副产物排放，并进一步分析了降解机理。结果表明，在单一等离子技术转化实验中，处理后的臭气混合物的转化率高于处理过的单一臭气，SO ₂和NO _{x的副产物排放}也由于反应过程中中间产物和副产物的反应而减少。在 6 L/min 的气体流速、16 kV 的电压和 200 Hz 的频率下处理时，气味混合物的绝对去除效果最佳。采用共沉淀法合成了M(Ce,Cu)-Mn/13X负载催化剂。在3~7 L/min的气体流量条件下，H ₂ S和NH ₃的去除效率和副产物排放量的降低排序为：未催化>Cu-Mn/13X>Ce-Mn/13X ，证明Ce-Mn/13X表现出较好的催化活性和应用价值。
