Detection of Reduced Sulfide and Odor Concentration in Sewage Treatment Plant using Electronic Nose |
| |
| Abstract: | 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. |
