摘要

  • 摘要: 为了研究潮汐流人工湿地对高污染河流污染物的去除效果及其影响因素,实验构建了潮汐流人工湿地系统。运行春夏两季以来,系统对TN、NH3-N、TP、COD和BOD5的平均去除率分别为49.14%、48.34%、79.40%、81.52%和83.39%;其中系统对TN和NH3-N的去除受到温度的影响,且温度变化对NH3-N去除效果的影响大于TN;在实验周期内,系统对TN、TP、COD和BOD5的去除均受进水污染负荷的影响,但却有着较好的抗负荷冲击能力;潮汐流人工湿地能够显著提高系统内溶解氧,使其不再成为去除污染物的限制性因素。
    Abstract: A tidal flow constructed wetland system was constructed to treat highly polluted river water and acquire information on the removal efficiencies of pollutants and assess the impact factors. During a half year's experiment (from spring to summer), the average removal rates of TN, NH3-N, TP, COD and BOD5 were 49.14%, 48.34%, 79.40%, 81.52% and 83.39%, respectively. The removal rate of NH3-N was easier affected by the temperature than TN. The unit removal of TN, TP, COD and BOD5 was affected by the influent loading, but the constructed wetland had a great capacity to resist the influence of load. Since the concentration of DO was greatly improved by the tidal flow constructed wetland, it would not be a limiting factor for pollutant removal any more.
