The concentration of suspended particle in sewage offers an important reference for testing water quality. This paper sheds new light on suspended solid concentration measurement with the Image Processing Technology (IPT) based upon different light reflex characteristics of water and suspended particles. With the Matlab, the probability-based insolation non-uniform correction algorithm and the Otsu threshold segmentation algorithm are used to simulate the sewage image, extract the area feature and calculate the concentration of suspended particles in sewage, which, in relation to true values, proves that the suspended solid concentration measurement based on the IPT seems more accurate and feasible, thus laying the foundation for studying the solid-liquid separation technology.
