摘要
【目的】探讨水体生态修复模式,为改善都市近郊水体水污染,保护水生态环境提供参考依据。【方法】在探明重庆市内子口水库基本条件及水污染种类与程度的基础上,针对库内(已受污染水体)与库外(污染源)分别采用不同修复措施。【结果】库内据污染情况于不同位置设置生态浮床980座;库外采用人工湿地与水源涵养林对污染水源进行处理,共设计2种规模6个垂直流人工湿地,并采用菖蒲、美人蕉等作为湿地植物,采用香樟、垂柳等植被于库周布置17280m2的水源涵养林。【建议】通过水生态修复与保护措施,利用植物对污染物的截留与吸收,可改善水库水质,但修复周期相对较长。
[Objective]Water ecological restoration measures and techniques were investigated to provide references for reducing water pollution and protecting water ecological environment in the cities and suburbs. [Method]Based on natural environmental conditions of Neikouzi reservior of Zhongqing City as well as water pollution types and degrees, biological floating bed, constructed wetland and ecological shelterbelt were applied in water restoration. [Result]Different restoration measures were used separately inside （polluted water） and outside the reservoir （pollution source）. Nine hundred and eighty biological floating beds were placed in different parts of the reservoir according to the water conditions. Outside the reservoir, 6 vertical flow constructed wetlands in two different scales were designed to treat pollution water sources using calamus and canna as wetland plants, at the same time, camphor and weeping willow trees were planted around the reservoir to form a water conservation forest of about 17280 m2. [Suggestion]Regardless of the long period, water ecological restoration and protection measures could improve water quality of the reservoir by use of plants to retain and absorb the pollutants.
