ABSTRACT
Acid mine drainage (AMD) is widespread environmental problem associated with both working and abandoned mining operation, resulting from the microbial oxidation of pyrite in presence of water and air, to form an acidic solution containing metal ions. The present study aims to adjust low pH, remove iron, manganese and sulphate from AMD generated at open pit Jiří and depth Jiří, Sokolovská uhelná, Czech Republic. The local AMD is very problematic due to its composition and process taking place in the Water Preparing Plant Svatava (WPPS), where only pH value is adjusted and mainly high concentration of iron and suspended solids are removed.

Możliwości zagospodarowania kwaśnych wód kopalnianych na przykładzie kopalni Sokolowska
wody kopalniane, żelazo, mangan, siarczany
Kwaśne wody kopalniane są szeroko rozpowszechnionym zagrożeniem środowiska związanym z zarówno czynnymi jak i wyeksploatowanymi kopalniami, a wywodzącym się z mikrobowego utleniania pirytu w obecności wody i powietrza. W wyniku tego procesu powstaje kwaśny roztwór zawierający jony metali. Obecne prace mają na celu skorygowanie niskiego odczynu pH, usunięcie żelaza, manganu i siarczanów z kwaśnych wód kopalnianych, które są generowane w czynnym szybie Jiri w kopalni Sokolowska w Czechach (Jiří, Sokolovská uhelná). Lokalne kwaśne wody kopalniane stanowią poważny problem ze względu na swój skład oraz na proces uzdatniania wody w oczyszczalni ścieków w Svatawie (WPPS), gdzie koryguje się jedynie odczyn pH i usuwa głównie z zawiesiny ciała stałe oraz najbardziej skoncentrowane żelazo.
