摘　　要：用电子鼻监测技术探究污水处理厂还原硫化物质量浓度和臭气质量浓度预测方法。结果表明,使用响应面分析法(RSM)建立还原硫化物质量浓度与电子鼻响应值关系,构建还原硫化物质量浓度预测模型,准确率可达95%。使用偏最小二乘法(PLS)建立不同质量浓度还原硫化物的传感器响应值与对应臭气质量浓度之间的关系,构建臭气浓度预测模型,并用实际样品验证。A method for predicting the concentration of reduced sulfide and odor in sewage treatment plant were developed by using electronic nose technology. Response surface methodology (RSM) was used to build the relationship between reduced sulfide concentration and the response value of electronic nose, and establish a model for reduced sulfide concentration prediction. The accuracy was up to 95%. Partial least squares (PLS) method was used to build the relationship between the sensor response value of reduced sulfide at different concentrations and the corresponding odor mass concentration, and establish a model for odor concentration prediction. The method was verified by actual samples.
