Abstract
One of the important factors determining the biochemical processes in bioreactors is the quality of the wastewater inflow to the wastewater treatment plant (WWTP). Information on the quality of wastewater, sufficiently in advance, makes it possible to properly select bioreactor settings to obtain optimal process conditions. This paper presents the use of classification models to predict the variability of wastewater quality at the inflow to wastewater treatment plants, the values of which depend only on the amount of inflowing wastewater. The methodology of an expert system to predict selected indicators of wastewater quality at the inflow to the treatment plant (biochemical oxygen demand, chemical oxygen demand, total suspended solids, and ammonium nitrogen) on the example of a selected WWTP—Sitkówka Nowiny, was presented. In the considered system concept, a division of the values of measured wastewater quality indices into lower (reduced values of indicators in relation to average), average (typical and most common values), and upper (increased values) were adopted. On the basis of the calculations performed, it was found that the values of the selected wastewater quality indicators can be identified with sufficient accuracy by means of the determined statistical models based on the support vector machines and boosted trees methods.
Highlights
The key factors having a significant impact on the operation of wastewater treatment plants, and the choice of setting values, include the quantity and quality of the influent wastewater [1,2]
They constitute independent variables in the process models for forecasting the operation of a treatment plant [3,4,5]. This is important in terms of the operation of the facilities, as having the values of wastewater quality indicators allows the simulation calculations of a biological reactor to be performed in advance using a process model
The results obtained in this work confirm that it is possible to identify the quality of selected indicators of wastewater quality on the basis of the results of measurements of the inflow to the treatment plant
Summary
The key factors having a significant impact on the operation of wastewater treatment plants, and the choice of setting values, include the quantity and quality of the influent wastewater [1,2] They constitute independent variables in the process models for forecasting the operation of a treatment plant [3,4,5]. The values of wastewater quality indicators at the inlet to the WWTP, as well as the amount of wastewater flowing into the WWTP, change over a wide range, e.g., as a result of heavy rains or uncontrolled discharges of pollutants into the sewage system This has a significant impact on the treatment process in the biological reactor. This approach usually does not take into account the operating costs of the treatment plant, which should be the main criterion for assessing the efficiency of WWTP operation
