A Research on Foam-Detection Based on Image Analysis in the Process of Sewage Treatment

At present, suspended solids and temperature detected by sludge concentration meter in sewage are commonly used as operational status data of oxidation pond in Chinese sewage treatment works. But there are some problems in this method such as the inaccuracy of detection and difficulty of maintenance. Therefore, the method of foam-detection based on image analysis in the process of sewage treatment analysis is introduced in this article and by which we can get the operational status of oxidation pond. It turned out that the Rate of Foam was better calculated with this method and the accuracy met the operational requirements.
