摘　　要：试验采用2套生物强化人工湿地单元,对垂直潜流人工湿地进行模拟。将外加菌种的湿地单元与空白单元进行对照,通过对溶解氧(DO)、p H、温度等外界因素变化的观察,来研究湿地系统对于氨氮、TN、TP、COD去除效果的具体影响。发现温度对湿地脱氮效果影响显著;沿水流方向,2套系统p H值呈现曲折下降趋势,DO的变化过程则是先降低后升高。Using two sets of biofortification wetland units to simulate vertical subsurface flowconstructed wetlands. Taking comparison of the wetland unit with additional strain and the blank unit,and through the observation of the changes among dissolved oxygen( DO),PH,temperature and other external factors,we study the specific removal effects of wetland systems for ammonia nitrogen,TN,TP,COD. We found that the influence of temperature on nitrogen removal in wetland is remarkable.Along the flowdirection,the two systems present that p H decreases tortuously,and DO increases after the first decrease.
