Abstract:

In the present study the Support Vector Method (SVM) is used to analyze the dependency between input variables (quantity and quality of wastewaters at the inflow and operational characteristics of an Activated Sludge Tank (AST)) and a result of predicted mixed liquor suspended solid (MLSS) and substrate loads (FIM). Computations revealed, that the highest errors for MLSS are present if only the load of organie compounds susceptible to chemical degradation was included in the input data and lowest when load of coal, ammoniacal nitrogen, suspension and ASCh's operational characteristics were used as the input. Moreover, it appeared that indices of wastewater quality at the inflow to the treatment plant can be sirnulated on the basis of the measured discharge and temperature of wastewaters and in a result it is possible replacing these measured indices with modeled ones to sirnulated MLSS and FIM. The lowest 'errors of predicted substrate loads, computed on th.e basis of modeled using SVM indices values were obtained for coal, arnmoniacal nitrogen, suspension loads and AST's operational characteristics - sludge temperature and pH and methanol dosage.
