Control of the Remediation of Anoxic AMD Groundwater by Sulphate Reduction in a Subsoil Reactor
Ralph Schöpke, Manja Walko
Abstract
Groundwater containing high amounts of products of pyrite weathering as a consequence of lignite mining flows into receiving waters for a number of years. Iron hydroxides causing turbidity and silting will strongly affect the river Spree for many decades. In addition to liming acidic surface waters and the conventional treating of mine waters, microbial sulphate reduction of the inflowing anoxic AMD groundwater is tested for long-term remediation. During a pilot project at Lusatia / Germany, glycerin as a carbon source and nutrient solutions of N and P are infiltrated into an anoxic AMD groundwater stream by lances. Planning and operations were carried out based on the model as proposed below. Doi: 10.28991/HEF-2022-03-03-02 Full Text: PDF
