| 摘 要： | 考察了新型人工湿地——塔式复合人工湿地（TICW）对农村生活污水的处理效果。结果表明，TICW对污染物具有较高的去除能力，脱氮效果尤其明显，对COD、NH4^＋-N、TN、TP的去除率分别为72％、82％、83％、63％；TICW的瀑布式水流增强了污水的充氧效果，湿地土壤中氨化菌、硝化菌的数量均较多，分别为10^7～10^8 CFU／g土壤和10^4～10^5 MPN／g土壤，提高了湿地的脱氮性能；木本植物和地方特有的经济作物——蔺草的结合使用使湿地在冬季仍能保持较高的除污能力。

| Abstract: | The treatment efficiency of rural domestic sewage by tower-type integrated constructed wetland was investigated. The results show that the removal efficiencies of COD,NH+4-N,TN and TP are 72%,82%,83% and 63% respectively. The oxygen content of sewage is increased due to the waterfall flow. The amounts of ammonifying bacteria and nitrifying bacteria in the wetland are 107 to 108 CFU/g (soil) and 104 to 105 MPN/g (soil) respectively,which improves the nitrogen removal performance of the wetland. The combined ... |
