ABSTRACT In this study, cattail (Typha latifolia) was used to remove Na+ and Cl− from polluted soil (PS) in a solid waste open dumping site. Hydroponic system was also evaluated to remove Na+ and Cl− from landfill leachate. The results indicated that the cattail grown in PS had higher biomass yield of 44.4 ± 3.29 g compared to that of control (35.3 ± 4.28 g). Nitrogen and phosphorous contents of cattails grown in PS were also higher than that of control plants, and the electrical conductivity of PS significantly decreased from 245 ± 1.40 to 51.9 ± 9.30 ms/m over the 5-week experimental duration. Na+ and Cl− contents from cattail grown on PS were 10.8 ± 1.85 and 64.7 ± 9.15 g/kg biomass, respectively. For cattails grown hydroponically in water containing leachate, nitrogen and phosphorous accumulation was 51.1 ± 5.94 and 9.32 ± 3.22 g/kg biomass, respectively. The corresponding biomass yield of these cattails was 13.5 ± 1.29 g at the end of 5 weeks. In addition, the Na+ and Cl− accumulation of 55.5 ± 4.82 and 78.2 ± 28.3 g/Kg biomass, respectively, was higher in hydroponic cattails grown in this study. Overall, the results suggest the effectiveness of cattails for phytoremediation of contaminated soil and the high efficiency of hydroponic system for nutrient and salinity removal compared to the conventional soil test.

香蒲(Typha latifolia)对垃圾倾倒场土壤和垃圾渗滤液的植物修复

摘要 在这项研究中,香蒲(香蒲)用于从固体废物露天倾倒场的污染土壤 (PS) 中去除 Na+ 和 Cl-。还评估了水培系统从垃圾渗滤液中去除 Na+ 和 Cl-。结果表明,与对照 (35.3 ± 4.28 g) 相比,在 PS 中生长的香蒲的生物量产量更高,为 44.4 ± 3.29 g。在 PS 中生长的香蒲的氮和磷含量也高于对照植物,PS 的电导率在 5 周的实验持续时间内从 245 ± 1.40 显着降低到 51.9 ± 9.30 ms/m。来自 PS 上生长的香蒲的 Na+ 和 Cl- 含量分别为 10.8 ± 1.85 和 64.7 ± 9.15 g/kg 生物量。对于在含有渗滤液的水中水培生长的香蒲,氮和磷的积累为 51.1 ± 5.94 和 9.32 ± 3.22 g/kg 生物量,分别。在 5 周结束时,这些香蒲的相应生物量产量为 13.5 ± 1.29 g。此外,本研究中种植的水培香蒲的 Na+ 和 Cl- 积累量分别为 55.5 ± 4.82 和 78.2 ± 28.3 g/Kg 生物量。总体而言,结果表明香蒲对污染土壤的植物修复的有效性以及与传统土壤测试相比的水培系统去除养分和盐分的高效性。图形概要 结果表明,与传统土壤测试相比,香蒲对受污染土壤的植物修复有效,以及水培系统在去除养分和盐分方面的高效性。图形概要 结果表明,与传统土壤测试相比,香蒲对受污染土壤的植物修复有效,以及水培系统在去除养分和盐分方面的高效性。图形概要
