目前的研究表明，某些参数，通常存在于城市垃圾渗滤液中，对水葫芦（凤眼莲crassipes），一种漂浮的水生植物，用于处理渗滤液时的生长的影响。研究了水葫芦在不同盐分离子浓度、营养盐、pH值和重金属浓度的垃圾渗滤液中的生长能力。水葫芦的能力，以消除一些参数，如氮，钾，磷，总固体，和氯离子进行了研究。所有实验均在温室环境中的分批反应器中进行。渗滤液样本收集自安大略温莎的埃塞克斯-温莎区域垃圾填埋场。结果发现，该处理系统需要存在足够量的营养物（N、P和K）以确保植物生长。当初始氯化物和钠浓度分别为560 mg L-1和330 mg L-1时，发生最佳生长。渗滤液pH值为0...
The current research demonstrates the effects of certain parameters, usually present in municipal landfill leachate, on the growth of water hyacinth (Eichhornia crassipes), a floating aquatic plant, when used for treatment of leachate. Experiments were carried out to investigate the ability of water hyacinth to grow in leachate with different salinity ions concentrations, nutrients, pH, and heavy metals concentrations. The ability of water hyacinth to remove some parameters such as nitrogen, potassium, phosphorus, total solids, and chloride were also investigated. All experiments were conducted in batch reactors in a greenhouse environment. The leachate samples were collected from Essex–Windsor Regional Landfill, Windsor, Ontario. It was found that this treatment system required the presence of sufficient amount of nutrients (N, P, and K) to ensure plant growth. Optimum growth took place when the initial chloride and sodium concentrations were 560 mg L–1 and 330 mg L–1, respectively. The leachate pH for o...
