摘　　要：基于三维响应面方法,采用Design Expert软件,研究了以苯酚、乙酸、萘为代表的模型化合物单组分、双组分及三组分有机物在热降解过程中的交互作用。采用响应面模型对热降解处理煤气化废水的COD降解率、NH_(3)-N降解率进行预测,分析了反应条件(温度、氧浓度、反应时间)对COD降解率、NH_(3)-N降解率的影响。研究表明,不同模型化合物降解由易到难为乙酸、苯酚、萘,萘对COD的降解具有抑制作用,而乙酸可以促进苯酚的降解;温度对煤气化废水COD降解率、NH_(3)-N降解率的影响最为显著。Based on the three-dimensional responsive surface optimization method,the interactive effects of one component,two components and three components of model compounds represented by phenol,naphthalene and acetic acid during the thermal degradation process of coal gasification wastewater were studied with the Design Expert software.The degradation rate of COD and NH_(3)-N in the wastewater thermal degradation was predicted with responsive surface model,with analysis on the impact of reaction conditions(including temperature,oxygen volume fraction and reaction time)on the degradation rate of COD and NH_(3)-N.The results showed that the degradation of different model compounds was respectively from easy to difficult degradation:acetic acid,phenol and naphthalene.Naphthalene had the suppressive effect on the degradation of COD,while acetic acid had the positive effect on phenol degradation.In addition,the reaction temperature had a notable effect on the degradation rate of COD and NH_(3)-N.
