摘　　要：受污染河道氮磷污染物削减及富营养化控制是水体修复的难点。本文以府溪河为例,开展生态修复试验。结果表明,沉水植被对水体总氮和硝态氮的去除效果明显,采用沉水植被协同固定化微生物技术,可以明显改善河道水质,强化对氨氮和总磷的去除,并有效控制藻类滋生。The reduction of nitrogen and phosphorus pollutants in polluted rivers and the control of eutrophication are the difficulties in water restoration.This paper takes Fuxi River as an example to carry out ecological restoration experiments.The results show that the submerged vegetation has obvious removal effect on total nitrogen and nitrate nitrogen in water,the use of submerged vegetation combined with immobilized microorganism technology can significantly improve the water quality of the river,strengthen the removal of ammonia nitrogen and total phosphorus,and effectively control the growth of algae.
