摘　　要：为利用等离子体处理持续有机污染物POPs,需要根据某些已有的POPs数据判断其对于各类POPs的销毁能力.基于Gibbs自由能最小原理和能量守恒原理建立了平衡计算模型,并与实验结果进行对照.结果表明,模型在给定有机废物组分和产物温度的情况下与实验结果符合较好.利用该模型模拟了加水量对等离子体温度区域范围内处理数种POPs的平衡产物,以及不同温度下的摧毁率.该方法可用于预测采用等离子体技术处理各种POPs的摧毁效果.In order to estimate the destruction efficiency for many sorts of POPs （the persistent organic pollutants） based upon the experimental data from several sorts of POPs destructed by plasma technology, this paper sets up an equilibrium model for predicting the reaction product distribution of organic wastes of given constituents under given reaction temperature. The model is based on Gibbs free energy principle and energy conservation, and agrees with experimental data very well. The results show that this model can be applied to predict the reaction products and de- struction efficiency for many sorts of POPs under different reaction temperatures, even under arc plasma temperature, and with water added.
