Problems solved by technology

However, during the treatment of black and odorous rivers, due to the difficulty of pipe network reconstruction, sewage interception is not complete, and there are still some sewage outlets in the river. At the same time, some rivers are connected to outer rivers or tributary ditches during treatment. , it affects the final governance effect

Embodiment 1

[0028] Example 1, such as Figure 1-3 As shown, the ecological interception zone structure 100, its extension direction isolates the clean channel and the polluted channel, and its cross-sectional shape is trapezoidal, and the trapezoid includes slope protection layers 110 on both sides and a central packing layer 120, and the slope protection layer 110 and the bottom of the packing layer 120 extend to The bottom of the river, the top is flat and 200mm lower than the normal water level. The slope protection layer 110 is surrounded by a plurality of ecological bags filled with purification fillers. Water plants above normal water level. The planting density of emergent plants is 9-25 plants / m 2 . Emergent plants include one or more of reeds, cattails, water chestnuts, water celery, water onions, wild rice stems, cattails, quinces, calamus, water philodendrons, windmills, and rushes. It also includes a plurality of permeable pipes 130 arranged side by side along the extension...

Embodiment 2

[0030] Example 2, such as Figure 4-6 As shown, the ecological interception belt structure 200 encloses the rainwater inlet, and its cross-sectional shape is trapezoidal. The trapezoid includes slope protection layers 210 on both sides and a central filling layer 220. The slope protection layer 210 is enclosed by a number of ecological bags. The material of the ecological bags is PP material. The ecological bags are filled with purification fillers. The purification fillers are ceramsite with a particle size of 2-3mm. Emergent plants are planted in the bag, and the emergent plants exceed the normal water level. The filler layer 220 has a trapezoidal cross-sectional shape, and it includes a mineral clay layer 221 , a ceramsite layer 222 , and a gravel layer 223 sequentially from bottom to top. The height ratio of the mineral clay layer 221 , the ceramsite layer 222 and the gravel layer 223 is 2:2:1. The particle size of the ceramsite layer 222 is 2-3 mm, and the particle size...

Abstract

The invention discloses an ecological interception belt structure. A clean riverway and a polluted riverway are isolated by the ecological interception belt structure in the extending direction; the cross section of the ecological interception belt structure is trapezoidal, and the trapezoid comprises slope protection layers on two sides and a center packing layer. The bottoms of the slope protection layers and the bottom of the packing layer extend to the bottom of a river respectively; the tops of the slope protection layers and the top of the packing layer are flush and are 200-300 mm lowerthan the normal water level; the slope protection layers are defined by a plurality of ecological bags; the ecological bags are filled with a purification packing; emergent aquatic plants are plantedin the ecological bags at the tops of the slope protection layers, and the emergent aquatic plants exceed the normal water level. The ecological interception belt structure is suitable for an ecological interception belt technology for isolating the clean riverway and the polluted riverway, is low in construction cost, and can be effectively fused with riverway landscapes.

Description

technical field [0001] The application relates to the field of ecological control of water body pollution, in particular to an ecological interception zone structure. Background technique [0002] Urban development and construction are closely related to water resources. Due to the lack of ecological protection measures in the construction of urban environment, coupled with the pollution of urban water resources and untimely cleaning of rivers, urban rivers have black and smelly phenomena, and the city's If the river course is not cleaned for a long time, harmful substances will be released. In addition, the water circulation capacity of some urban rivers is relatively poor, and the fluidity of water bodies is relatively weak. The living environment of aquatic plants and animals in the rivers cannot be improved, which will affect the self-purification ability of urban rivers, and eventually the color of the water will gradually turn green, and then Black and smelly phenomen...
