【摘要】 将多层次、多物种配置的植物床的生活污水处理效果与传统植物配置方式的污水处理效果进行了比较,研究了多层次、多植物种配置在人工湿地系统中污水处理的有效性和可行性。研究中,对CODCr、BOD5、TP、TN和NH3-N的去除率,传统植物配置的植物床分别达到了69.0%、71.6%、78.5%、33.6%和36.7%,多层次配置的植物床分别达到了65.7%、64.6%、84.5%、20.2%和18.3%。结果表明,多层次、多植物配置的植物床能有效去除污水中的污染物。另外,在人工湿地中进行多层次、多物种配置时,有必要结合植物筛选工作,以确保配置更有效。更多还原

【Abstract】 Comparing the plantbeds with multiplayer plants configuration with those with traditional plant configuration, the research was focused on the domestic wastewater treatment in constructed wetland. As to CODCr, BOD5, TP, TN and NH3-N, the removal rates in the traditional plants configuration got to 69.0%, 71.6%, 78.5%, 33.6% and 36.7% , irrespectively, and 65.7%, 64.6%, 84.5%, 20.2% and 18.3% in multiplayer plants configuration plantbeds. It indicated that the plantbed with multiplayer plants configuration could decrease the pollutants effectively. However, it is noteworthy that plants selection is necessary when different plants are collo- cated together.更多还原
