Salvinia herzogii, Pistia stratiotes and Eichhornia crassipes (floating species) were the dominant macrophytes in a constructed wetland (CW) over the first years of operation. Later, the emergent Typha domingensis displaced the floating species, becoming dominant. The industrial effluent treated at this CW showed high pH and salinity. The aim of this work was to study the tolerance of floating species and T. domingensis exposed to different pH and salinity treatments. Treatments at pH 8, 9, 10 and 11 and salinities of 2,000; 3,000; 4,000; 6,000; and 8,000 mg L were performed. Floating macrophytes were unable to tolerate the studied pH and salinity ranges, while T. domingensis tolerated higher pH and salinity values. Many industrial effluents commonly show high pH and salinity. T. domingensis demonstrated to be a suitable macrophyte to treat this type of effluents.
水鳖、大漂和凤眼蓝（漂浮物种）是运行初期人工湿地（CW）中的优势大型植物。后来，挺水植物香蒲取代了漂浮物种，成为优势物种。该 CW 处理的工业废水具有高 pH 值和高盐度。本工作旨在研究漂浮物种和香蒲在不同 pH 值和盐度处理下的耐受性。在 pH 值为 8、9、10 和 11 以及盐度为 2000、3000、4000、6000 和 8000 mg/L 的条件下进行了处理。研究表明，漂浮大型植物无法耐受所研究的 pH 值和盐度范围，而香蒲则能耐受更高的 pH 值和盐度值。许多工业废水通常具有高 pH 值和高盐度。香蒲被证明是处理这种类型废水的合适的大型植物。
