Utilization of stabilized soil in landfill constructions
2009 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

The thesis investigate the impact of different waste materials (gypsum, fly ash, sewage sludge) and peat together with zero-valent iron on the immobilization of arsenic from a chromate-zinc-arsenate (CZA) contaminated soil. The remediated soil should used as a secondary material for the vegetation layer of a landfill. The test was performed in a gravity column test with different sampling horizons (50cm, 100cm, 200cm). The layer with 50cm and 100 cm shows low arsenic concentrations. This thickness could reach the requirements of the EU landfill directive (1999/31/EC).The thesis shows promising result for gypsum-, peat-, sewage sludge- and only iron-treated soils, but with reservations. The arsenic concentration decreased, but mainly in the top and middle segment. For fly ash treated soils the arsenic concentration increased in all segments in comparison to a blank. Further studies for the iron- gypsum-, peat- and sewage sludge mixture are required, especially a field study under natural conditions.
