Soil Surface Biotreatment
Abstract Construction Biotechnology can be used for ground surface fixation of soil particles to control water and wind erosion of soil, to control dust and dispersion of radioactive, chemical, and bacteriological pollutants in atmosphere, to mitigate the dune movement and dust storms in sand deserts, and to seal the surface of ponds, channels, reservoirs, and landfills to diminish seepage of water. After biotreatment of the fine sand with the dosage of precipitated Ca 15.6 g/m2, the release of the sand dust and its artificial pollutants to atmosphere decreased in comparison with control by 99.8 % for dust, 92.7 % for phenantherene, 94.4 % for led nitrate, and 99.8 % for bacterial cells of Bacillus megaterium. The calculated consumption of calcium during construction of model pond was 0.7 kg Ca/m2 for biocementation by spraying, 1.2 kg Ca/m2 for biocementation through precipitation of calcite from the covering solution, and 0.2 kg Ca/m2 was used for the biocementation of the small cracks in the dried model pond.
