Performance evaluation of pilot scale sub-surface constructed wetlands was carried out in treating leachate from Pulau Burung Sanitary Landfill (PBSL). The constructed wetland was planted with Cyperus haspan with sand and gravel used as substrate media. The experiment was operated for three weeks retention time and during the experimentation, the influent and effluent samples were tested for its pH, turbidity, color, total suspended solid (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD(5)), ammonia nitrogen (NH(3)-N), Total phosphorus (TP), total nitrogen (TN) and also for heavy metals such as iron (Fe), magnesium (Mg), manganese (Mn) and zinc (Zn) concentrations. The results showed that the constructed wetlands with C. haspan were capable of removing 7.2-12.4% of pH, 39.3-86.6% of turbidity, 63.5-86.6% of color, 59.7-98.8% of TSS, 39.2-91.8% of COD, 60.8-78.7% of BOD(5), 29.8-53.8% of NH(3)-N, 59.8-99.7% of TP, 33.8-67.0% of TN, 34.9-59.0% of Fe, 29.0-75.0% of Mg, 51.2-70.5% of Mn, and 75.9-89.4% of Zn. The significance of removal was manifested in the quality of the effluent obtained at the end of the study. High removal efficiencies in the study proved that leachate could be treated effectively using subsurface constructed wetlands with C. haspan plant.
采用香蒲（Cyperus haspan）构建潜流人工湿地对巴生鸟岛垃圾填埋场渗滤液进行了中试规模的处理效果评估。人工湿地的基质为沙砾。实验运行了三周的停留时间，在实验过程中，对进水和出水样本进行了 pH 值、浊度、颜色、总悬浮固体（TSS）、化学需氧量（COD）、生化需氧量（BOD5）、氨氮（NH3-N）、总磷（TP）、总氮（TN）以及铁（Fe）、镁（Mg）、锰（Mn）和锌（Zn）等重金属浓度的测试。结果表明，香蒲人工湿地能够去除 7.2-12.4%的 pH 值、39.3-86.6%的浊度、63.5-86.6%的颜色、59.7-98.8%的 TSS、39.2-91.8%的 COD、60.8-78.7%的 BOD5、29.8-53.8%的 NH3-N、59.8-99.7%的 TP、33.8-67.0%的 TN、34.9-59.0%的 Fe、29.0-75.0%的 Mg、51.2-70.5%的 Mn 和 75.9-89.4%的 Zn。研究结束时获得的出水质量证明了去除效果的显著意义。研究中去除效率高，证明了采用香蒲植物构建的潜流人工湿地可以有效处理渗滤液。
