Decrease in the trophic status of a second-order oligotrophic stream (Zbytinský Potok) by a new wastewater treatment plant with two low-loaded stabilisation ponds

Popis výsledku v původním jazyce

The village Zbytiny requires higher wastewater treatment efficiency than usual for a village of its size. This is because of the occurrence of freshwater pearl mussels in the Blanice River. The wastewater treatment plants (WWTP) designed for municipalities up to 500 inhabitants are efficient for treating organic pollution, but their treatment efficiency for total nitrogen and phosphorus is relatively low. Therefore, a unique solution was chosen in Zbytiny; two low-loaded stabilisation ponds, connected in a series, were built in addition to a new mechanical biological WWTP. These stabilisation ponds are used to post-treat wastewater discharged from the WWTP. The results from two years of regular monitoring clearly show a positive influence of these stabilisation ponds on total treatment efficiency. The best results from post-treatment in the stabilisation ponds were observed for total nitrogen and phosphorus, which showed treatment efficiencies of 38% and 88%, respectively.
