摘要：This study presents the results of the analysis concerning the influence of the amount of inflowing wastewater on concentrations of organic and biogenic pollutants, as well as chromium ions in wastewater flowing into the collective sewage treatment plant in Nowy Targ. The research was carried out in 2016 and 2017, where in the period of 24 months a total number of 87 wastewater samples were collected in order to determine the concentration of the analyzed pollution indicators. During this period, the average daily inflow of wastewater to the sewage treatment plant was also analyzed. Based on the analysis of linear correlation, it was stated that there is a high dependence of concentrations of organic and biogenic pollutants on the amount of inflowing raw wastewater. Furthermore, it was found that there is an average dependence of chromium ion concentrations in raw wastewater on the amount of inflowing wastewater. In order to minimize the high variability of the concentration of pollutants in raw wastewater, it is recommended to reconstruct the sewerage system from the combined sewer system to the distribution system. Additionally, it is recommended to monitor the sewerage network in order to eliminate illegal inflows of rainwater and industrial wastewater from furrier’s production facility.
