摘要
通过中试试验,研究地表漫流系统中马尼拉、水香蒲、春兰、早熟禾等4种植物对新沂河污水中CODMn、氨氮、色度3个指标的去除效果.试验结果表明:4种植物中,早熟禾对污染物的去除效果最佳,CODMn、氨氮、色度去除率分别达到55%,89 2%,51 2%;在考察的3个指标中,地表漫流系统对氨氮的去除率最高,4种植物对其去除率分别达到78 8%,79%,67 6%,89 2%.
Through a pilot-scale experiment of the overland flow system, four plants, i.e. Zoysia matrella, Typha, (C.goeringii,) and Poa Pratense, were compared about their efficiencies in removal of COD_(Mn), NH_3-N and chroma from the wastewater of the Xinyi River. The results show that the removal effect of Poa Pratense is the best of the four plants, the removal rate of COD_(Mn), NH_3-N and chroma reaching 55%, 89.2% and 51.2%, respectively, and that NH_3-N is most effectively removed among the three studied indices, the removal rate of NH_3-N reaching 78.8%, 79%, 67.6%, and 89.2% by the four plants respectively.
