METHOD AND MEASURING DEVICE FOR AUTOMATICALLY DETERMINING THE CONCENTRATION FACTOR OF CONDITIONED SEWAGE SLUDGE |
摘要 |
The invention relates to a method for automatically determining the concentration factor of conditioned sewage sludge. The inventive method comprises the following steps: the flocculation structure of the sewage sludge flow (2) is detected by means of one-dimensional, photo-optical incident light measurement of scanning lines of the grey value progression of a sewage sludge control, perpendicularly in relation to the flow direction; the chord lengths and/or running lengths of the detected flocculation structure are determined from the grey value progressions, said chord lengths and/or running lengths being equal to the distance between a relative grey maximum value and an adjacent relative grey minimum value; the frequency distribution of the chord lengths and/or running lengths is calculated; the concentration factor is determined according to the parameters which are determined from the chord lengths and/or running lengths and/or the frequency distribution of said chord lengths and/or running lengths. |
