Optimalizace provozu Čistírny důlních vod - Březno u Chomutova

Abstract

The extraction of brown coal is the dominant industrial sector for Northern Bohemia lignite basin, which is connected with creation of mine water from surface extraction. It is however necessary for these waters to be adjusted before draining so there is no reduction of quality of surface water and then underground water. The thesis is devoted to the issue of pre-adjusting of mine waters and their cleaning in the mine water treatment plant Března u Chomutova. I am describing a function of this treatment plant and a technological process of cleaning of mine water. Next I am following up legislative requirements, which are related to demarcation of concept of mine water and its treatment. The main part of the thesis is to suggest a new technology for pre-adjusting of mine water, which can prevent draining of unpurified mine water from compensatory tank to the watercourse Hutná, therefore violanting terms established by state administration for draining of mine water. Furthermore the costs for cleaning will be reduced and hydraulic leakiness of mine water treatment plant will be increased for at least 100 1.s-1
