In this study, to establish an optical measurement device to measuring water level ,MLSS concentration, SS concentration and Sedimentation rate。The measuring device used LED, laser light and camera as a component of the building。Use of image analysis techniques to obtained information ,and used the information measuring water level ,MLSS concentration, SS concentration and Sedimentation rate。The simple measuring device could be monitoring a variety of information。The experimental results, the maximum water level measured error values to 0.32cm, MLSS measurement error is 200 mg/L, SS measurement error is 13.8 mg /L. Furthermore, the measuring device can provide sludge sedimentation rate information that general MLSS sensor unable to monitor。 |
