Ecological water environment treatment system for sandy riverbed of mountainous river channel
The invention discloses an ecological water environment treatment system for a sandy riverbed of a mountainous river channel. The ecological water environment treatment system comprises an ecological green island arranged in a river center region of the river channel, an ecological buffer zone arranged close to a river bank, an ecological protection slope arranged close to a main river channel and an ecological interception ditch arranged in the water flowing direction. Dwarf willow herbs, iris wilsonii, pennisetum alopecuroides and juniperus procumbens are sequentially planted in the green land of the ecological buffer zone from the waterside to the beach land. Two retention and deposition zones are arranged in the middle of the dwarf lythrum salicaria, and a pelelith retention and deposition zone and a zeolite retention and deposition zone are sequentially arranged from the water facing side. The water environment treatment system can effectively resist river channel scouring and water and soil loss caused by a large longitudinal slope; water resources can be planned as a whole, water quality is improved, and non-point source pollution is reduced; the arrangement of the water environment treatment system is an effective measure for reducing nitrogen and phosphorus loads, and the rural human settlement environment can be improved.
本发明公开了一种山区河道砂质河床生态水环境治理系统，包括设置在河道河心洲地带的生态绿岛、靠近河岸设置的生态缓冲带、靠近主河槽设置的生态护坡以及沿流水方向设置的生态拦截沟；生态缓冲带的绿地从临水侧至河滩地依次种植矮生千屈菜、黄花鸢尾、狼尾草、铺地柏；矮生千屈菜中部设置有两条滞留沉积带，且从临水侧依次设置为火山石滞留沉积带、沸石滞留沉积带。本发明的水环境治理系统能有效抵御较大纵坡带来的河道冲刷、水土流失；能统筹水资源、提升水质，降低面源污染；本水环境治理系统的设置是降低氮磷负荷的有效措施，能改善农村人居环境。
