【摘要】 与传统活性污泥法的人工湿地处理技术不同,人工湿地系统的重要特点在于其通常具有水生植物,水生植物的直接和间接作用增强了湿地的污染物去除能力和改善了生态环境,其中植物供氧是一个重要因素。而水量平衡对于湿地处理效果的衡量具有重要的意义,碳、氮和磷平衡有助于理解湿地系统的污染物的迁移转化规律。湿地的进水量和出水量通常不等,准确计量湿地的进水水量和出水水量非常必要。更多还原

【Abstract】 Significant characteristic of constructed wet land different from traditional active sludge system is that there is helophyte in the former has but no helophyte in the latter.The direct and indirect function of the helophyte intensified the contaminants removal capacity and improved the eco-environment.Oxygen provision by helophyte is one of the important reasons.Balance of water discharge has significant sense for the evaluation of the contaminants removal effect in the system.Carbon,nitrogen,and phosphorus balance can help people understand the contaminant transportation and conversion regularity in the constructed wet land.The inflow and outflow of constructed wetland are usually different,thus the accurate measurement of them are necessary.更多还原
