Embodiment Construction

[0026] like figure 1 , 2 As shown, an ecological riparian belt combined with river water purification and slope green space maintenance includes an ecological bed in the riparian zone, a water regulation tank 3, a sandless concrete imitation wooden column connecting plate 10, a portable submersible pump 1 and a water delivery pipeline 2, The ecological bed of the riparian zone consists of upper and lower layers. The upper layer 8 is the soil layer of the river bank slope and plants 7 are planted on it. The plant 7 is a single plant or a mixture of multiple plants among local species, and the vegetation covers rate ≥ 95%; the lower layer 9 is a cushion layer paved with pebbles or crushed stones from bottom to top in order of decreasing particle size, and microorganisms and rotifers are attached to the lower layer 9;

[0027] In the upper layer 8 of the ecological bed in the riparian zone, several water distribution main pipes 5 are arranged in parallel along the direction of v...

Abstract

The invention provides an ecological riparian zone combining river purification and slide slope greenbelt conservation. The ecological riparian zone comprises a riparian zone ecological bed, a water body adjusting trough, a non-sand-concrete wooden pole connecting plate, a portable submersible pump and a water conveyance pipeline. Slide slope greenbelt plants are irrigated by raising a river while a vegetation-microorganism-soil system in the riparian zone is utilized to intercept and purify pollutants in the rising river, and the purified water body reenters a riverway. The influent mode of the invention has strong suitability to the water quantity and the water quality and has stable and reliable water quantity purification effect, low engineering investment and operation cost, simple operation maintenance and management and obvious purification effect on the micropolluted riverway. The riverway water body not only is an irrigation water source for the slide slope greenbelt vegetation in the riparian zone to supply irrigation water for the greenbelt plants, but also saves water resources and the conservation cost of the greenbelt plants.

Description

technical field [0001] The invention relates to an environment-protecting ecological riparian zone, in particular to an ecological riparian zone capable of purifying river water and maintaining slope green space, and belongs to the field of water environment management and ecological restoration. Background technique [0002] With the acceleration of industrialization and urbanization in my country, the water quality of rivers continues to deteriorate, and it is imperative to improve river water quality and ecological restoration. The existing river water quality improvement methods mainly include physical methods, chemical methods and ecological restoration methods. Physical methods such as river sediment dredging, water diversion and drainage, etc. These methods treat the symptoms but not the root cause, and do not remove the pollutants in the river water body from the water body, so they can only be used as an emergency measure. Chemical methods such as adding chemical a...
