三种生态方法处理刘家湖水体富营养化的对比研究

以刘家湖为实验对象进行了研究，对其原水质进行了采样、监测和分析。分别采用了生物接触氧化膜、人工生态浮床和人工湿地三种生态方法进行试验。通过三种方法对湖水的处理，比较分析其对水中氮、磷的去除效果。实验结果表明，这三种生态方法具有很好的水质净化效果，氮、磷等的去除效果明显，湖水经处理均达到了《地表水环境质量标准））（GB3838-2002）中的Ⅵ类标准，使水质指标达到了渔业用水标准。生物接触氧化膜法较人工生态浮床工艺和湿地相比，具有更高的效率。

Research on Comparsion of Liujiahu Water Treatment by Three Ecological Methods

The research on the water of Liujiahu was carried out. The water samples was monitored and analysis. Three ecological methods, aquamats, man-made ecological floating beds and constructed wetland were used in the experiment, respectively. The removal of nitrogen and phosphorus was compared and analysis by three methods of water treatment. The result showed that, all of the aquamats, man-made ecological floating beds and constructed wetland have a good water purification and high efficiency of removing nitrogen and phosphorus. The water quality reached the Surface Water Environment Quality Standard class IV. Compared with man-made ecological floating beds and constructed wetland method, the aquamats methods have the highest efficiency.
