| 英文摘要 | The purification law of nitrogen in deyeuxia angustifolia, carex lasiocarpa and deyeuxia angustifolia-carex lasiocarpa combined wetland systems in the sanjiang plain, china was studied by field simulation experiment. the results indicate that the removal rates of tn, nh(4)(+)-n and no(3)(-)-n in above three types of wetlands present an obvious logarithm growth trend along with the time. there are evident removal effects for nr(4)(+)-n and no(3)(-)-n in water bodies of wetlands after the 30th day of experiment, with the removal rates over 80.0%, but the removal rate of tn is slightly low, being 63.1%-74.3%. no(3)(-)-n is most quickly removed by the combined wetland, and nh(4)(+)-n by deyeuxia angustifolia wetland. the removal speeds of tn by the three wetland systems are comparatively slow, of which the deyeuxia angustifolia wetland is the fastest. in consideration of plant growth season, deyeuxia angustifolia wetland has much more practical application value in purifying nitrogen. these results can provide references for the study on the purification function of wetlands and the control of non-point source pollution in northeast china. |
