| 英文摘要 | Environmental contamination caused by extra heavy oil-based drill cuttings (DCs) is a major problem in the Liaohe Oilfield, northeastern China. To study the potential effectiveness of the mature reed wetland in removing extra heavy oil contained in drill cuttings, biodegradation of extra heavy oils and study of the effects on soil property and ecophysiological and quality indices of reeds were carried out in a 2-year in situ pilot experiment. In the wetland, four reed beds were used to treat drill cuttings in various loadings: 0 (control), 5, 20, and 40 ks/m(2), corresponding to 150, 600, and 1200 g/m(2) extra heavy oil hydrocarbons (HCs). The obtained results demonstrate that the mature reed wetland was effective at degrading extra heavy oils without extra fertilization. Removal efficiencies of reed bed 2 in the 0- to 80-cm soil profile increased with time, from 90.1% (first harvest season) to 95.8% (second harvest season). After 2 years. only 4.2% of the initial hydrocarbons residual was retained in the surface soil. There was no apparent adverse effects on the surface soil property during degradation of extra heavy oils and, actually, the deeper soil property and reed quality indices were improved at the end of the experiment. Phytotoxicity, resulting in reduction of reed yield, was observed in the most heavily treated beds in the first year. However. tong-term reed yield recovered robustly. During the 2-year period, reed height and leaf number were slightly inhibited. (C) 2003 Elsevier Ltd. All rights reserved. |
