| 摘 要： | 河流在人类社会中扮演着非常重要的角色，但是由于城市的快速发展，人类对河道水体的过度使用以及随意将污染物排放入河流中，致使水体中N、P含量超标，河道水环境的污染问题越来越严重。为净化水体，降解水中污染物，改善河道整体水环境，此次采用原位生物膜技术对河道水环境进行修复。从试验河道采集水样，初始阶段每天采样1次，稳定运行后采样间隔时间为4天、7天、11天，共计采集14个水样。结果表明：在微生物膜稳定运行32天后，从上游M1至中游M2，原位生物膜对NH4+-N的去除率最高达65.28%；从上游M1至下游M3，整个原位生物膜对NH4+-N的去除率最高达66.67%。研究表明原位生物膜技术去除NH4-N的效果明显，能有效地改善河道水环境，为城市河道的原位治理提供借鉴意义。 |

| Abstract: | The river plays an important role in the development of the human society. But because of the rapid development of the cities, human overuse of river water and random discharge of pollutants into the rivers, the pollution of river water environment is becoming more and more serious. The biofilm technology is used to repair the water environment of the river in order to purify the water body and improve the overall water environment of the river. Water samples were collected from the trial river channel. In the initial stage, samples were taken once a day. After stable operation, the sampling interval was 4 days, 7 days and 11 days. A total of 14 water samples were collected. The results showed that the removal rate of ammonia nitrogen (NH4+-N) reached 65.28% from M1 to M2 after 32 days of stable operation of the microbial membrane. And that reached 66.67% from M1 to M2. The research shows that the effect of removing NH4+-N by in-situ biofilm technology is obvious. It can effectively improve the river water environment and provide reference for the in-situ treatment of urban rivers. |
