| 摘 要： | 根据实验性模拟垂直流人工湿地进、出水数据和系统动力学的研究方法,运用STELLA系统动力学软件对模拟垂直流人工湿地脱氮过程进行建模分析。STELLA分析结果表明:构建的STELLA动力学模型能较准确地模拟垂直流人工湿地对废水中NO-3-N、NH+4-N、TN的去除率,但对废水中有机氮去除率的模拟性较差;在运行正常的情况下,该模型可以对垂直流人工湿地系统氮的去除过程进行描述,并可为其处理出水浓度变化的预测提供理论依据。

| Abstract: | Based on our experimental effluent data and the VFCW system dynamics, a STELLA model was developed to analyze the nitrification and denitrification processes. Results showed that the STELLA model had a poor prediction on the removal of organic nitrogen, but a better simulation on NO3--N, NH4+-N and TN removals. This study suggests that the STELLA model developed can be used to predict the nitrogen removal in a VFCW system under normal operational conditions, and therefore provides a theoretical basis to predict the effluent quality in the VFCW system. |
