| 摘 要： | 采用水平潜流人工湿地中试系统处理采油废水,考察湿地植物生长状况对污染物去除效果的影响,运用气相色谱-质谱(GC-MS)技术分析湿地植物对有机污染的吸附情况,并分析了湿地植物对氮、磷的吸收效果。研究结果表明:人工湿地出水达GB 8987—1996《污水综合排放标准》中的一级标准。湿地植物的生长状况与人工湿地的COD及NH 4+-N去除率呈现一定的耦合关系。芦苇及藨草均能吸附多种难降解有机污染物。植物吸收是人工湿地去除氮、磷的途径之一,但并非主要途径。

| Abstract: | The pilot system for horizontal subsurface flow constructed wetlands was applied to treat oilfield produced wastewater,it was examined the effect of wetland plant growth conditions on the removal of pollutants.Gas chromatography-mass spectrometry(GC-MS) was used to analyse the effect of wetland plants on the adsorption of organic pollution,also the rate of wetland plants on the uptake of nitrogen and phosphorus.The results show that the effluent quality reached the first-order inIntegrated Wastewater Discha... |
