Description
Technical Field
The utility model belongs to the technical field of water pollution ecological treatment facilities, and particularly relates to an ecological buffer device for river water body treatment.
Background
The surface runoff on two sides of the river channel is mainly suspended particles, but due to the complexity of pollution sources, the components are complex and changeable, a large amount of nutrient substances or organic substances such as nitrogen, phosphorus and the like are carried, and the substances migrate into the water body to possibly cause eutrophication of the water body and harm the ecological environment of the water, so that the bearing load of the river channel on external pollution is greatly improved.
Therefore, buffer belts for ecological treatment of water pollution are arranged on two sides of the river channel, and the surface runoff flows into the river channel after interception and purification, so that the water pollution can be treated properly to the greatest extent in the river entering process. And the adjacent water area in the buffer zone is mainly a arbor and tree zone, arbor and shrub species can protect the embankment, reduce river bank erosion, intercept sediment, absorb stagnation nutrients, remove pollutants and increase the habitat of wild animals. However, under the influence of the current environmental conditions or the soil properties, part of the river channels have no natural ecological buffer zone.
An existing ecological buffer device for sewage treatment is disclosed in, for example, a Chinese patent with a patent publication number of CN210764589U and a publication date of 2020.06.16: an ecological buffer zone comprising a main carrier and emergent aquatic plants. In this ecological buffer zone, the main carrier is including the geotechnique cloth of connecting the river bottom to and polymer material fibre, forms the unable adjustment base of emergent aquatic plant, and the developed root system of emergent aquatic plant can produce appropriate quality of water purifying effect to rainfall runoff at last.
The ecological buffer belt in the patent of the utility model is mainly based on the following principle: the side carrier is used for planting and fixing emergent aquatic plants, the side carrier is connected with the riverbed through geotechnical cloth, and finally the emergent aquatic plants can filter and purify precipitation at the riverbank.
However, this ecological buffer zone has at least the following 2 disadvantages in the actual use process.
First, the side carriers and the river bed are connected by geotextiles only, and the strength of the connection is far from sufficient. In other words, when the surface runoff is large, the whole ecological buffer device may be directly flushed away.
Secondly, the water quality is purified by only relying on emergent aquatic plants, the plant configuration is single, and particulate matters and a large amount of pollutants in surface runoff are difficult to block and enter the river, so that the purification capability is far insufficient when the surface runoff pollution with a large amount of pollutant types and large flow is faced.
Therefore, in summary, a strong-efficiency ecological buffer device with firm installation and high-efficiency water purification is needed, so as to make up for the ecological buffer zone where some rivers are missing or difficult to recover, increase pollutant interception capability, and reduce exogenous pollution of water.

Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1-9, the ecological buffer device for river water body treatment structurally comprises a blocking pile unit 1 with the lower end inserted on a river bed, a rear end reinforcement cage unit 2 arranged on the blocking pile unit 1, a lower packing layer 3 and an upper planting soil layer 4 arranged in the rear end reinforcement cage unit 2, and a front arbor zone 5, a middle shrub zone 6 and a rear herbal zone 7 arranged on the upper planting soil layer 4.
In this embodiment, the blocking pile unit 1 uses pine piles, and the rear end reinforcement cage unit 2 is mainly used to fix the lower packing layer 3 and the upper planting soil layer 4, so as to avoid that the packing and soil are washed away by surface runoffs in a large amount.
In addition, the lower filler layer 3 adopts common modified fillers for water purification, such as porous lightweight ceramsite, polyethylene microsphere, porous carbon block and the like, and can further carry out modification measures such as sintering, alkali washing and the like, so that relatively strong adsorption and interception capability on pollutants in water is ensured.
In addition, elm, cedar, maple and the like are planted in the front arbor zone 5, the root system is developed, the soil fixing force is strong, the water is resistant to water flooding, nitrogen and phosphorus elements in sewage can be absorbed in a large amount, and the water quality can be intercepted and purified. The middle shrub area 6 is planted with fine leaf water-blown flowers, dustpan willows and the like, and the roots are large in quantity and wide in root system distribution. The rear herbal area 7 is planted with arundo donax, galbana and the like, has developed root systems, vigorous growth and strong soil fixing force, and can filter a large amount of sediment and chemical substances in water. Finally, the overgrowth of floating algae can be inhibited, and the amount of nitrogen and phosphorus elements in the water body can be obviously reduced, so that the ecological buffer device has more comprehensive and efficient water quality purifying effect. The water body of the surface runoff flows into the river channel and then needs to pass through the front arbor zone 5, the middle shrub zone 6 and the rear herb zone 7 in sequence, which is the origin of the names of the three zones.
Finally, the blocking pile unit 1 blocks the water impact force of the surface runoff in front, and the rear-end reinforcement cage unit 2 is connected with the blocking pile unit 1 in the rear for reinforcement, so that the ecological buffer device is not easy to wash away even when facing the surface runoff with large water quantity.
The blocking pile unit 1 comprises a rectangular frame body 101 for the front arbor zone 5 to extend out of the root system, two groups of mounting holes 102 respectively arranged on an upper transverse plate and a lower transverse plate of the rectangular frame body 101, and lower fixing piles 103 and upper protruding piles 104 respectively arranged on the upper mounting holes 102 and the lower mounting holes 102 in a plugging manner.
It is well known that the growth direction of roots has mainly 3 characteristics: the water-and soil-and fertilizer-directing properties, while in this embodiment the thickness and space of the upper planting layer 4 is far from sufficient for the developed root system of the front arbor zone 5, and below is the relatively dense lower packing layer 3.
In addition, a large amount of sludge and impurities are intercepted on the blocking pile unit 1, and a large amount of nitrogen and phosphorus factors are enriched. Therefore, the developed root system of the front arbor zone 5 is downward according to the principles of geotropic and fertile, then horizontally faces the shore, finally extends out of the rectangular frame 101 and then downward until being pricked into a river bed, and is shaped like a vertical Z shape.
Therefore, the rectangular frame 101 provides a wide root growth space for the front arbor zone 5. Finally, the arbor can strengthen the whole ecological buffer device, which is very critical.
The blocking pile unit 1 further comprises a reinforcement ring 105 which is sleeved over the lower fixing pile 103 or the upper protruding pile 104.
In this embodiment, the lower fixing piles 103 are provided with lower tips, and the reinforcing rings 105 are made of resin strips, which are respectively used for "turning the lower fixing piles 103 and the upper protruding piles 104 into whole" to improve the water impact resistance of the blocking pile unit 1.
The rear end reinforcement cage unit 2 comprises vertical reinforcement bars 201, transverse reinforcement hoops 202 sleeved on all the vertical reinforcement bars 201 and used for fixedly placing the lower packing layer 3, and annular non-woven fabrics 203 sleeved on all the vertical reinforcement bars 201 and used for fixedly placing the upper planting soil layer 4 and used for enabling the front arbor zone 5 to extend out of a root system.
In this embodiment, the length of the vertical reinforcement bars 201 is greater than the annual average river depth, and the height of the upper surface of the upper planting soil layer 4 is slightly lower than the annual average river depth and is also lower than the upper end edge of the annular non-woven fabric 203.
The mesh specification formed by the vertical reinforcing ribs 201 and the transverse reinforcing steel hoops 202 is smaller than the minimum particle size of the lower packing layer 3, so that the packing is prevented from being washed away by the surface runoff water body in a large amount.
The transverse reinforcing steel bar hoop 202 may be provided inside the annular nonwoven fabric 203, and the steel wire tightening and fixing operation may be performed between the annular nonwoven fabric 203 and the vertical reinforcing steel bars 201 or the transverse reinforcing steel bar hoop 202.
Finally, the pores on the annular non-woven fabric 203 are relatively small, so that the planting soil is not easy to run off, but the root system of the front arbor zone 5 is enough to jack up and puncture the annular non-woven fabric 203 when extending transversely.
The blocking pile unit 1 further comprises arc-shaped grooves 106 provided on the sides of the upper and lower transverse plates of the rectangular frame 101 and used for clamping the vertical reinforcing bars 201.
In this embodiment, the shape of the arc-shaped slot 106 is a major arc, that is, the number of central angles is greater than 180 °, and the vertical reinforcement ribs 201 may be inserted into the arc-shaped slot 106 from top to bottom, so that the vertical reinforcement ribs and the rectangular frame 101 are not easy to laterally separate, and the rear-end reinforcement cage unit 2 is prevented from being washed away by surface runoff water.
In addition, the vertical reinforcement bars 201 may be fastened together with the annular nonwoven fabric 203 into the arc-shaped groove 106, and the installation height of the horizontal reinforcement hoop 202 needs to avoid the upper and lower transverse plates of the rectangular frame 101.
The rear end cage unit 2 further includes a bottom reinforcement mesh 204 provided at a lower end position of the vertical reinforcement bars 201.
In this embodiment, the transverse reinforcing steel bar hoop 202 and the bottom reinforcing steel bar mesh 204 are rectangular, and the vertical reinforcing steel bars 201 are fully welded or fastened.
The blocking pile unit 1 further includes a connection plate 107 provided between the upper protruding pile 104 and the arbor 5-1, and a connection string 108.
In this embodiment, the height of the upper end surface of the upper protruding pile 104 is higher than the average annual water level, so that it can be used as a growth fixing rod for the arbor 5-1, and the arbor 5-1 is not easy to fall down in the whole growth process.
Wherein, the two ends of the connecting plate 107 are respectively clamped with the upper protruding pile 104 and the arbor 5-1, and the connecting ropes 108 bind and tie the upper protruding pile 104 and the arbor 5-1 together. Of course, the length of the connection plate 107 and the length of the connection rope 108 are required to be increased in size during the growth cycle of the arbor 5-1, so as not to interfere with the growth of the arbor 5-1.
The filler 3-1 is a porous filler, and the particle size range of the filler 3-1 is 1-5cm.
In this embodiment, the packing 3-1 is divided into 3 batches, the first batch has a particle size range of 4-5cm, the first batch is laid on the bottommost layer in the rear end reinforcement cage unit 2, the middle batch with a particle size of 2-4cm and the upper batch with a particle size of 1-2cm are sequentially arranged upwards, and the upper planting soil layer 4 is arranged above the first batch. The particle size gradient structure can enable the upper filler to adsorb harmful pollutants to the greatest extent, and the lower filler can properly allow water to permeate, after all, the pollutants are mainly concentrated at the upper part in the water.
The thickness of the upper planting soil layer 4 is 15-20cm.
In this embodiment, this 15-20cm planting soil thickness is sufficient for shrubs, herbs, but far from sufficient for the arbor 5-1, so the rectangular frame 101 is provided so that the arbor 5-1 eventually takes root directly on the riverbed.
The average water level line a is higher than the upper surface of the upper planting soil layer 4.
In this embodiment, the mean water line a is at least water line data of about three years, and its height passes right through the rear herbal zone 7, so that the herbal plants can intercept a lot of floating algae, floating garbage, etc.
Finally, if the blocking pile unit 1 is separated from the river bank by a certain distance, most of the garbage carried by the surface runoff is accumulated in the water body, and the garbage is required to be periodically salvaged at the moment, and if the blocking pile unit 1 is contacted and attached to the river bank, most of the garbage carried by the surface runoff is accumulated on the river bank, and the garbage is required to be periodically cleaned at the moment.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
