Problematika nákládání s důlními vodami - důl Lazy

Abstract

While crossing the town of Orlová following Ostravská street, connecting Ostrava and Karviná, it is impossible to overlook several ponds where rushes grow and many fishermen sit. However, it is not widely known that this area is used to treat waste waters from the Lazy mine. I have decided to describe properly this very interesting process. The aim in this bachelor thesis is to describe main teritorry conditions of plant Lazy and system of biological ponds. In the following chapters are comparisions of choiced contaminants in waste waters with present law. The final section is devoted to the overview of elimination methods of choiced contaminants.
