摘　　要：目前中国湖泊的水体环境日益恶化,一些湖泊甚至出现水华等水体富营养化现象。利用水生植物联合微生物强化修复技术治理水体富营养化污染具有经济性、无二次污染等优点,对治理水体富营养有很重要的意义。本研究设置对照组(CK)、水芹菜组(P)、水芹菜+氮循环细菌组(P+I)三个实验组来处理富营养污水。结果表明:水芹菜组(P组)和水芹菜+氮循环细菌组(P+I组)对总氮(TN)、氨氮(NH4+-N)、CODMn、叶绿素a的去除率均较好,与对照组(CK组)有显著性差异(p<0.05),能显著提高水体透明度,水芹菜组(P组)和水芹菜+氮循环细菌组(P+I组)对总氮的去除率分别为73.5%和76.3%,两者在最终的总氮去除率上无显著性差异,但水芹菜+氮循环细菌组(P+I组)表现出更高的去除效率;水芹菜组(P组)和水芹菜+氮循环细菌组(P+I组)对氨氮的最大去除率分别为52.8%和62.1%,水芹菜+氮循环细菌组(P+I组)对氨氮的最终去除率明显高于水芹菜组(P组)(p<0.05);水芹菜联合氮循环菌在高氮素废水中显示出更高的去除率,但在过高的浓度下去除率也有降低的趋势。At present,the water environment of lakes in China and even worse,some lake water bloom water eutrophication phenomenon,taking advantage of aquatic plants combined bioremediation technology of controlling eutrophication is economic,no two pollution,and has very important significance for the governance of water eutrophication.In this study,the control group（CK）,water celery group（P）,water celery＋nitrogen cycling bacteria group（P＋I） three groups to treatment of eutrophic wastewater,the results showed that the P group and P＋I group of total nitrogen（TN）,ammonia nitrogen（NH4＋-N）,CODMn,the removal rate of chlorophyll a well,there was significant difference with CK group（p〈0.05）,can significantly improve the transparency of the water,increasing water alkalinity; P group and P＋I group,the total nitrogen removal rate were 73.5% and 76.3%,both total nitrogen in the final removal rates no significant difference,but the P＋I showed better removal efficiency; P group and P＋I group on the maximum removal rate of ammonia nitrogen were 52.8% and 62.1%,P ＋I group of ammonia nitrogen removal rate was significantly higher than that of P group（p〈0.05）; water celery with nitrogen cycle bacteria in high nitrogen wastewater showed better removal rates,but at higher concentration on removal rate also decreased the trend.
