Problems solved by technology

Permeable spurs prevent river bank erosion mainly by reducing flow velocity. Current research on permeable spurs mainly focuses on protecting river banks, such as hydraulic characteristics and erosion-silting effects, and does not have the function of improving river water quality and ecology.

Embodiment 1

[0028] The structure of embodiment 1 permeable spur dam system

[0029] Such as Figure 1~3 As shown, the ecological permeable spur system of the present invention includes at least one permeable spur, and the permeable spur extends from the river bank to the channel, and the permeable spur includes a pile unit, a nutrient-adsorbing unit and a plant unit, and the pile unit It includes a plurality of wooden piles 1 arranged at intervals in sequence; the nutrient-rich adsorption unit is arranged between two adjacent wooden piles, and the nutrient-rich adsorption unit includes a variety of mixed fillers 2 that can absorb and enrich nutrients The plant unit is planted on the upper part of the eutrophic adsorption unit, and the plant unit includes at least one aquatic plant 3 .

[0030] The ecological permeable spur dike of the present invention can be a first-level ecological permeable spur dike consisting of one permeable spur dime, or a third-level ecological permeable spur dik...

Embodiment 2

[0036] The water body purification effect of embodiment 2 permeable spur dikes

[0037] 1. Comparing the water purification effect of the third-level ecological permeable spur dam and the first-level ecological permeable dam

[0038] Three prefabricated ecological permeable spur dams are placed equidistantly in the simulated river, the water level is 5cm, the dam length is 1 / 4 or 1 / 2 the river width, the dam length of the first-level ecological permeable dam is the same as the river width, and the artificially simulated river water is Simulate one-time flow in the river. The sampling sections are set at 5cm in front and behind the dams of spur dikes at all levels, and the water outlet is 1 meter away from the last section. The sampling interval is 12 hours, and the analysis is completed within 24 hours after the sampling.

[0039] Specific results such as Figure 4 The results show that the removal rate of TN, TP, ammonia nitrogen and COD of the first-level ecological perme...

Abstract

The invention belongs to the field of riverway water body ecological remediation, and particularly relates to an ecological permeable spur dike system. The ecological permeable spur dike system is composed of a plurality of ecological permeable spur dikes, a gabion grid is placed on the inner side of a spur dike pile column, the inner part of the gabion grid is filled with absorption filling materials, and aquatic plants are planted on the upper layer. According the ecological permeable spur dike system, the function that river banks are not directly washed by incoming flows is achieved, the action that pollutants such as nitrogen and phosphorus in river water are held back and absorbed is achieved, riverway water quality can be improved, conditions are created for growth and inhabitationof aquatic organism, restoration of the riverway partial ecological environment is promoted, and biodiversities are increased.

Description

technical field [0001] The invention belongs to the field of ecological restoration of river channel water bodies, and in particular relates to an ecological permeable spur dam system. Background technique [0002] The river course is the carrier of the water system and an important part of the ecosystem. At present, many rivers in China have problems such as black odor, eutrophication, and sharp decline in biodiversity. The functional restoration and health restoration of rivers have become urgent problems to be solved. [0003] Groove is a widely used structure for river regulation, and there are two forms of permeable spur and impermeable spur. The main function of the spur dike is to prevent or reduce the erosion of the water flow on the slope bank, and it also has the function of improving the channel. Permeable spurs prevent river bank erosion mainly by reducing flow velocity. Current research on permeable spurs mainly focuses on protecting river banks, such as hydra...
