摘要
为分析不同水生植物与水体中营养物质含量间的关系,了解不同水生植物对水质的净化效果,通过在石佛寺人工湿地采集并对比不同水生植物区域内水体中COD Cr、TP、TN和COD Mn含量,研究不同水生植物对水质的净化效果。结果表明:水生植物对于水质的净化效果明显,有水生植物种植的区域内营养物质含量明显低于无水生植物种植的区域。不同水生植物对水质的净化效果有较大差异,挺水植物区域强于由其他3种水生植物组成的混合植物区域,挺水植物中芦苇对水体中COD Cr和TP的净化效果最好;水烛对COD Mn的净化效果最好;芦苇和水烛对TN的净化效果较为接近,但明显强于荷花。
In order to analyze the relationship between the content of nutrients in different aquatic plants and water bodies,and to understand the purification effect of different aquatic plants on water quality,the COD Cr,TP,TN and COD Mn contents in water bodies in different aquatic plants were collected and compared in the artificial wetland of Shifo Temple.Study the purification effect of different aquatic plants on water quality.The results showed that the purification effect of aquatic plants on water quality was obvious,and the content of nutrients in areas where aquatic plants were planted was significantly lower than that in areas where aquatic plants were grown.The purification effect of different aquatic plants on water quality is quite different.The emergent water plant area is stronger than the mixed plant area composed of three other aquatic plants.The reeds in the emergent plants have the best purification effect on COD Cr and TP in water bodies;The purification effect of COD Mn is the best;the reed and water candle are closer to the purification effect of TN,but obviously stronger than the lotus.
