天津塘沽作为滨海新区核心区，是目前天津发展最快的地区之一。由于本区盐碱土壤等自然条件，污水中盐分含量较高，制约了废水的回用。本文通过模拟人工湿地实验，比较了芦苇（Phragmites australis）、盐地碱篷（Suaeda salsa）、碱蒿（Artemisia anethifo原lia）、黄花鸢尾（Iris wilsonii）、盐角草（Salicornia europaea）和大米草（Spartina anglica）等耐盐植物对轻污染水体中高浓度氯离子的去除能力，筛选出去除能力较强的植物，并确定植物对盐分去除率达到最大时的生态系统条件。结果表明，适合人工湿地的耐盐碱植物对氯离子的去除效果依次为：芦苇>盐地碱篷>碱蒿>黄花鸢尾>盐角草>大米草，停留时间一般在第4d时可达到平衡。该研究为利用人工湿地处理高盐废水提供了科学依据。

Tanggu, as the core area in Binhai New Area, is currently one of the fastest developing areas in Tianjin City. Because of the saline alkali soil and other natural conditions, wastewater reuse is restricted by high salinity. The removal of high concentration chloride by Phrag-mites australis, Suaeda salsa, Artemisia anethifolia Weber, Iris wilsonii, Salicornia europaea, and Spartina anglica in light polluted water was compared by the simulation experiment of artificial wetland. The plants with stronger removal ability were selected and the ecosystem condi-tion with maximum removal rate was determined. The results showed that the removal effect of chloride by salt-tolerant plants in artificial wetland was:Phragmites australis>Suaeda salsa>Artemisia anethifolia>Iris wilsonii>Salicornia europaea>Spartina anglica. The removal efficiency reached balance after four days. This study provided a scientific basis for the high salinity wastewater treatment by artificial wet-land.
