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.

Zastosowanie programu komputerowego »Dyspozytor« jako narzędzia w procesie regulacji rozpływu wody w kolektorze »Olza«
(Wydawnictwa AGH, 2010) Swolkień, Justyna
The article treats about the usage of »Dyspozytor« application in mine waters' flow regulation inside the »Olza's« interceptor sewer. Lack of its regulation is a main reason for huge variations of chlorides and sulphates concentration in the Odra river what in the end drives its ecosystem to the total destruction. Computer calculations show that in order to remain stable chlorides and sulphates concentration it is necessary for each interceptor sewer's object to work with a proper working parameters'. The computer program, together with »Olza's« interceptor sewer, helps to regulate water flow from each mine. It determines what kind of water class is possible to obtain taking into consideration river flow and its earlier contamination. Thanks to it is possible to maintain constant chlorides and sulphates concentration due to the exact water class. It is also possible to maintain low pressure in the interceptor sewer's pipelines what improves its energy consumption.
