Abstract

PURPOSE: To control activated sludge process waste water treating facilities in a highly scientific and technological way based on a theory of statistical probability by placing a confidence limit upon estimated values obtd. by analyzing observed values gathered in operation.
CONSTITUTION: After operation conditions are decided, according to decided operation conditions 2 estimated values and a confidence limit are modification- calculated 3 to judge 5 whether measured values are within the limit or not. When the measured values are without the limit, it is concluded that the response structure of activated sludge has induced a change of a statistically significant difference. At this time, until the measured values become estimatable within the limit 5, observed values are removed 6 from an observed value file in the order of oldness, duplicate regression analysis 7 is performed, and calculation 8 of estimated values and a confidence limit is repeated. When the measured values are within the limit, present measured values are added 9 to the file again, and duplicate regression analysis 10 is performed to prepare a regression equation for the next estimate. This equation has estimating capacity even when the response structure of activated sludge is changing.
