Description

Ecological riparian zone combining river water purification and slope greenbelt maintenance

Technical Field

The utility model particularly relates to an ecological riparian zone that river purification and side slope greenery patches maintenance combined together.

Background

Along with the acceleration of the industrialization and urbanization process of China, the water quality of the river water body is continuously deteriorated, and the improvement of the river water quality and the ecological restoration are not slow enough. The existing river water quality improvement methods mainly comprise a physical method, a chemical method and an ecological restoration method. Physical methods such as river sediment dredging, water transfer and drainage and the like are used for treating the symptoms and the root causes, pollutants in river water are not removed from the water, and the method can be only used as an emergency measure. Chemical methods such as adding chemical agents such as alum, lime and ferric salt into water body need to consume a large amount of agents when solving the problem of water quality of large water body, are high in cost and are easy to cause secondary pollution. The ecological restoration method, such as a river shorn (sunken) water plant restoration method, an ecological floating bed (island) method, a wetland restoration method and the like, utilizes specific organisms to absorb, convert and degrade pollutants in a water body, transfers the pollutants from river water into the organisms, gradually restores the ecological function of the water body, and is an economic and effective river water body purification method.

The methods all belong to methods for in-situ treatment of water bodies. The method for purifying the river water body by using the riparian zone belongs to a water body ectopic treatment method and also belongs to an ecological restoration method. The riparian zone is a crossing zone of a river land ecosystem and an aquatic ecosystem and is a buffer zone between a land non-point source pollutant and a river water body. In general, the bank zone is used for preventing non-point source pollutants on land from entering the river and further polluting the water body of the river.

In addition, urban greening is an important component of urban infrastructure construction and urban ecological environment construction, and is not only a symbol of a modern city, but also a civilization sign of the modern city. Along with the continuous improvement of urban greening degree in China, the water demand for urban greening is larger and larger. However, China is a country with serious shortage of water resources, nearly two thirds of cities in China have perennial shortage of water supply, and the large water demand generated by urban greening further aggravates the contradiction between supply and demand of urban water resources. Meanwhile, in order to ensure that the vegetation of the green land grows well and fully exert the function of the green land, a large amount of manpower and material resources are required for the maintenance of the green land, wherein the irrigation cost of the green land accounts for about 70-80% of the total cost of the maintenance of the green land. Therefore, under the condition that urban water resources are in shortage day by day and the capital of greening construction is in shortage, finding a green land irrigation water source on a river channel side slope and reducing the green land maintenance cost become one of the most concerned problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art, and provides an ecological riparian zone combining river water purification and side slope greenbelt maintenance, which comprises a top platform, a slope paved with a clinoptilolite layer and a bottom platform, wherein the top platform is provided with a solid wood guardrail; a water seepage ditch is arranged between the solid wood guardrail and the slope; a biological ceramsite layer is laid on the clinoptilolite layer, and a plurality of first filling bags are stacked on the surface of the biological ceramsite layer along the slope direction; a ceramic membrane partition plate inserted into the ground bottom is arranged at the junction of the bottom platform and the slope toe; a plurality of second filling bags are stacked at the slope toe along the vertical direction, and one end of each second filling bag is abutted against the ceramic membrane partition plate; the first filling bag and the second filling bag are both filled with solidified soil, and the solidified soil is prepared by adding STW (super soil cement) high polymer material into natural soil; ryegrass is planted at the slope toe part of the slope, and shading trees are planted at the slope waist part of the slope; and a dry season water storage ditch is arranged between the bottom platform and the ceramic membrane partition plate.

In order to better realize the maintenance of the slope green land, preferably, the bottom end of the solid wood guardrail is connected with a concrete cushion layer, and the concrete cushion layer is buried underground the top platform.

Preferably, green vegetation and shrubs are planted between the top and the bottom of the slope.

In order to better realize the purification of river water, natural zeolite is preferably paved in the dry season gully.

Preferably, the angle of the slope with the horizontal is less than 30 °.

Preferably, the bottom wall of the water seepage ditch is made of porous cement concrete, and the bottom wall of the water seepage ditch is adjacent to the inclined zeolite layer of the slope.

Has the advantages that:

the utility model discloses in, rainwater, flowing water and eutrophic sewage can be stored in the infiltration ditch at the top platform, permeate along the overburden layer slowly through porous cement concrete, can supply with moisture for the greenery patches vegetation on the slope on the one hand, and on the other hand can hold back infiltration aquatic through the clinoptilolite layer

Because the STW high polymer material contains a large amount of hydrophilic carboxyl and hydroxyl, the solidified soil in the filling bag also has high hydrophilicity, the filling bag on the slope can continuously extract water from river water to support green vegetation on the slope, and meanwhile, the water permeating downwards is adsorbed by clinoptilolite

The biological ceramsite adsorbs phosphorus elements to achieve the effect of purifying river water; the viscosity of the STW high polymer material is 400-3000 Mpa.s, so that the solidified soil has high stability, and further pollution to a water body caused by rain wash and mud stone landslide is avoided; the ryegrass has vigorous requirements on N and P elements, can efficiently remove the N and P elements adsorbed in each layer, prevents clinoptilolite and biological ceramsite from being adsorbed to saturation, further indirectly improves the river water purification efficiency, and simultaneously ensures the greening degree of the side slope; the shading trees planted on the slope can shade sunlight, reduce the temperature of the river surface in high-temperature weather, and effectively reduce the times of algae outbreak caused by high temperature, thereby realizing the purification of river water.
