Wpływ modernizacji systemu retencyjno-dozującego »Olza« na jakość wód rzeki Odry, Olzy i Leśnicy
(Wydawnictwa AGH, 2009) Swolkień, Justyna
This article treats about the influence of dropping system »Olza« modernization on the Odra, Lesnica and Olza rivers ecosystem. Both, Leśnica and Olza were the most jeopardize ones, taking into consideration the fact that the mine waters were directly thrown to their waters. Strongly contaminated, mostly with chlorides and sulphates, mine waters, transported through the interceptor-sewer, managed to destroy the whole rivers ecosystem. Huge chloride fluctuations were the cause of biological balance dysfunction. Most of animals and plants species were destroyed. The brake through came after the new dropping system was activated. The new system was placed in the bottom of Odra river and was equipped with 51 nozzles settled down between two river banks. The new system allowed to eliminate the contamination of the Leśnica and Olza rivers and prevented their flora and fauna from total distraction. It also allowed to mix the mine and the river waters just after the drop. It led to the elimination of huge chloride fluctuation in the Odra river and had a huge impact on its quality improvement.
