ACID MINE DRAINAGE TREATMENT BY ASH FROM WOODEN CHIP COMBUSTION: STUDY OF MINE WATER COMPOSITION IN DEPENDENCE ON THE ASH DOSE AND DURATION OF MUTUAL INTERACTION

Popis výsledku v původním jazyce

The biomass ash (BA) from wooden chip combustion was used in the treatment of acid mine drainage (AMD) from open cast brown coal mining in the Czech Republic. The used AMD is characteristic of high contents of SO42- (1576 mg.l-1), Fe (20 mg.l-1), Al (15mg.l-1), Mn (5 mg.l-1) and low pH (2.7), which need to be adjusted. The biomass ash samples were obtained through the combustion of wooden chips in an industrial boiler in Hodonín Power Plant, Czech Republic, and they predominantly contain SiO2 (45 wt.%), CaO (17 wt.%), Al2O3 (13 wt. %), MgO (6 wt.%), Fe2O3 (4 wt.%), K2O (3 wt.%), SO3 (3 wt.%), P2O5 (2 wt.%), unburnt materials and metals. The AMD treatment process included dosing of biomass ash (doses of 2.9 g, 6 g and 20 g of BA) to adjust the pH values to 8, 10, 12. The experiments observed the pH values and turbidity in selected time intervals within 7 days. Samples were analysed for metal contents, which had been abundant either in AMD or ash, or in AMD and ash simultaneously, in se
