Winding organic matter prediction calculation method and water quality prediction calculation method

摘要

PROBLEM TO BE SOLVED: To provide a new method of predictive calculation of pickup of organic matter, by which the pickup of an organic matter from sludge can be calculated predictively, and to provide a new method of predictive calculation of water quality. SOLUTION: The method of predictive calculation of pickup of organic matter includes a step of predictively calculation the pickup of a suspended matter from the sludge, and a step of converting the predictively calculated pickup of the suspended matter into the pickup of the organic matter from the sludge, based on the relational expression expressing the concentration of the picked-up suspended matter and the concentration of the organic matter contained in the picked-up suspended matter, as a function of the concentration of the suspended matter picked-up.
