为提高电石渣的资源化利用，实现以废治废，以改性电石渣为脱硝剂，采用单因素法研究了反应温度、氧含量、NO浓度对电石渣脱硝的影响，并利用响应面分析法优化改性电石渣脱除NO的工艺.探讨各因素对NO脱除率的影响，确定了脱硝最佳工艺条件：反应温度276.81℃、氧含量4.71%、NO浓度559.62 mg/m3.利用回归分析法建立了回归模型，其结果表明：NO浓度对NO脱除率有极显著影响，在最优条件下得到NO脱除率为99.56%.
Abstract：In order to improve the resource utilization of calcium carbide slag and realize waste treating waste with waste, the effects of reaction temperature, oxygen content and NO concentration on the denitrification of calcium carbide slag were studied by single factor method with modified calcium carbide slag as denitrification agent, and the NO removal process of modified calcium carbide slag was optimized by response surface methodology. The effects of various factors on NO removal rate were investigated, and the optimum denitrification conditions were determined as follows: reaction temperature was 276.81℃, oxygen content was 4.71%, and NO concentration was 559.62 mg/m3. The regression model was established by regression analysis method, and the results showed that NO concentration had a significant effect on NO removal rate, and the removal rate of NO was 99.56% under the optimal conditions.
