Nitrogen removal experiments for phytoremediation tank

This dataset contains the measured values obtained from a phetoremediation vessel (bench scale). The plant within the vessel Lemna minor L., has the capacity to take up nutrient ions as the plant grows and increases its biomass. The nitrate uptake (the nitrogen species selected to test the removal capability) is propotional to the amount of acid used to reduce the pH level in the vessel back to the desired setpoint at which the medium is controlled at. Included in the dataset is the measured mass amounts of the plant, the measured pH in the vessel and the measured nitrate concentration at a particular time. In Run 1 to Run 3, the vessel was operated in batches. The initial mat density varied: the vessel in Run 1 was very dense and Run 2 and Run 3 were inoculated below the full capacity of 200 grams per square metre (surface area). In Run 4 to Run 6, the vessel was operated continuosly beyond the full capacity of the vessel.本数据集收录了台式规模植物修复（phytoremediation）反应容器的实测数据。容器内种植的植物为小浮萍（Lemna minor L.），其在生长并累积生物量的过程中能够吸收营养离子。本研究选取硝酸盐作为测试氮去除性能的目标氮形态，硝酸盐的吸收量与为将容器内培养液pH回调至预设控制值所投入的酸试剂剂量呈正比。数据集包含特定时间点下的植物生物量实测值、容器内pH实测值以及硝酸盐浓度实测值。在第1至第3轮运行中，容器采用分批式运行模式，初始浮萍垫密度存在差异：第1轮运行的容器内浮萍垫密度极高，而第2、3轮运行的接种密度低于以表面积计的每平方米200克满负荷标准。在第4至第6轮运行中，容器采用连续式运行模式，且运行负荷超出了容器的满负荷设计能力。
