Turbulence condition low concentration sludge settlement rate measuring method and the measuring device

Method and apparatus for measuring the low concentrations of one kind of sludge sedimentation rate of turbulent conditions, thereby acquiring measured data by processing the image sludge sludge, image acquisition device is connected with a measurement computer through the data line, the metering computer comprising: an image capture module , the image processing module and the image measuring module, a measurement module for performing the image data acquired by the image processing module operation, to obtain a sludge sedimentation rate test, comprising a sludge particle size measuring sub-module for image processing image acquisition module sludge, sludge average particle diameter calculated image, to calculate the actual average particle diameter is measured according to the conversion ratio of the sludge; sludge sedimentation rate measurement sub-module, for two processing modules according to acquired for video, and calculates the rate of movement of the sludge on the image, by calculating the ratio of the actual conversion rate of sludge settling. The present invention has a high measurement precision, and measurement of the advantages of quick, easy and automated.
