Posouzení vhodnosti technologie sanace vod ekologické zátěžové oblasti v ostravských Lagunách a porovnání s jinými technologickými postupy

Abstract

This thesis deals with the evaluation of water environmental remediation technologies used in the environmentally hazardouss area of Ostrava lagoons and compared the effects with other technological processes. The first part of the thesis is focused on technologies that are used for sanitation works during the removal of contaminated water and soil. It also describes the technologies that are used for disposal of contaminated sites. In the second part of the thesis the author introduces the history of Ostrava lagoons, with the waste quantity, their size, fauna and flora. He describes various lagoons and their content. The third part of the thesis, focuses on technological processes of the remediation of lagoon water, sanitation inside the underground sealing walls, outside the underground sealing walls in situ biodegradation using biosparing, and free RU phase draining. The fourth experimental part of the thesis deals with the valid legislation, the comparsion of values of treated water at the inputs and output of the lagoon water treatment plant and the efficiency of lagoon water treatment plant of decontamnation plants. In the conclusion of this thesis the suitability of remediation methods, used in the Ostramo lagoon is evluated.
