浮萍净化氮磷污水生长条件研究

Growing conditions of five species of duckweed for nutrient-rich wastewater treatment

摘要: 对分布在长江三角洲地区的5个浮萍品种，通过不同环境温度下氮磷模拟污水化学需氧量(COD)、总氮(TN)和总磷(TP)三因素三水平正交试验，分别确定了5个浮萍品种在氮磷污水中的最佳生长条件，从而为进一步筛选长江三角洲地区高效净化氮磷污水的浮萍优化品种及其氮磷污水净化技术革新提供了基础。

Abstract: With orthogonal tests of three levels of Chemical Oxygen Demand(COD), Total Nitrogen(TN) and Total Phosphorus(TP) in artificial nutrient-rich wastewater at different ambient temperatures, the optimum growth conditions of five species of duckweed collected from the Yangtze River Delta were studied. The results could be applied to superior duckweed species selection, with which nutrient-rich wastewater treatment could be renovated in the Yangtze River Delta.
