摘　　要：水质维护是景观水体日常管理的难点和主要工作内容,以湖北省武汉市某景观水体为例,探索了原位生态修复集成技术对景观水体的维护效果。在该工程中,主要使用集成技术中的“层流曝气复氧技术+复合微生物菌剂”对水体进行治理与维护。结果表明,氨氮去除率达到88.67%,总氮去除率达到76.69%,总磷去除率达到53.23%,后期主要水质指标稳定。施工前,景观水体内大量乌龟死亡,水体黑臭,景观效果极差。施工后,水体异味消除,水中乌龟、鲤鱼等水生动物正常生活,提高了整个景区的环境质量。实践证明,该集成技术可使景观水体水质良好,为城市景观水体的水质维护提供了工程案例。Water quality maintenance is the difficulty and main work content of daily management of landscape water.Taking a landscape water body in Wuhan,Hubei Province as an example,the maintenance effect of in situ ecological restoration integrated technology on landscape water bodies was explored.In this project,the"laminar flow aeration re-oxygenation technology+compound microbial inoculum"in the integrated technology is mainly used to treat and maintain the water body.The results show that the NH_(3)-N removal rate reaches 88.67%,and the TN removal rate reaches 76.69%,the TP removal rate reached 53.23%,and the main water quality indicators were stable in the later period.Before construction,turtles died occasionally in the release pond,the water was black and smelly,and the landscape effect was extremely poor.After the construction,the odor of the water is eliminated,and aquatic animals such as turtles and carp in the water live normally,which improves the effect of the entire scenic spot.Practice has proved that the integrated technology can make the water quality of the landscape water body good,and provides an engineering case for the water quality maintenance of the urban landscape water.
