【摘要】 利用人工湿地处理生活污水,考察了湿地植物光合作用特性及其与污染物净化效果的关系。结果表明,植物净光合速率Pn与湿地COD、TN去除率显著正相关,而与TP去除率关系不大。在实际工程中,可将植物光合速率作为湿地植物选择的重要依据之一。更多还原

【Abstract】 To investigate the relationship between photosynthesis and contamination removal efficiency,constructed wetlands were used to treat urban sewage.Results showed that Pn was positively relative to the removal efficiency of COD_Cr while TN was less relative to the removal efficiency of TP.Therefore Pn could be used as one of important indexes of purification capability of the plants in practical engineering.更多还原
