WWTP - Opis:
- The paper constitutes the analysis of hydraulic load of a local wastewater treatment plant in the south-eastern Poland along with the analysis of sewage receiver hydraulic capacity and related receiving waters protection. Assuming that the daily outflow of treated sewage should not exceed 10% of the mean-low flow (SNQ) of the receiver, no case of daily sewage outflow greater than 10%·SNQ = 51 840 m3·d-1 was recorded. Moreover, average daily hydraulic load of the treatment plant was lower than the limit value by over 70% and the maximum recorded value – by over 40%. Furthermore, the conducted analysis shows that the particular months differed from each other in the values of the daily hydraulic load of the wastewater treatment plant at the outflow; May was the month with the highest average daily sewage outflow, while September was characterized by the lowest average daily outflow of treated sewage. There was also no clear dependence between the hydraulic load of the WWTP and the day of the week. Daily sewage outflows ranging from 10 000 m3·d-1 to 12 000 m3·d-1 constituted the largest part of all observations. The daily sewage outflows directed to the receiver prove that there is no threat to the preservation of the water environment quality.
