摘　　要：通过漂浮栽培的方式并采用实验统计的方法,对比种植物处理生活污水,测定分析了污水中氨氮、磷酸盐和总磷的含量变化情况。结果表明,芹菜(Apium graveolens)和吊兰(Herba Chlorophyti Laxi)经28天生长之后,生长良好,生物量大,其鲜重分别是初始种植时的3.3倍和3.86倍。芹菜和吊兰对污水总磷的去除率分别为79.5%、88%。对铵态氮的去除率分别80%、80.3%。对CODcr的去除率分别为71.2%、76.33%。芹菜、和吊兰在漂浮植物修复系统栽培中具有很好的净化效果和应用前景。By way of cultivation of floating, the statistics method is used to compare the ability of Apium graveolens and Herba Chlorophyti Laxi in treating sewage, and the changes of ammonia nitrogen, phosphate and total phosphorus in waste - water is determined. The results show that celery （Apium graveolens） and bracketplant （Herba Chlorophyti Laxi） after 28 days grow well with high biomass, and its fresh weight is respectively 3.3 times and 3.86 times of the initial planting. Celery and bracketplant of the sewage phosphorus removal rate is 79.5% and 88% respectively. The removal rate of nitrogen to ammonium is respectively 80%, 80.3%. The removal rate of CODcr is 71.2% and 76.33% respectively. Celery and bracketplant cultivation in floating plant repair system has the very good purifying effect and application prospect.
