Description

Technical Field

[0001] The utility model relates to an artificial wetland water purification system, and more specifically, to an artificial wetland water purification system with a filler structure capable of being quickly replaced. Background Art

[0002] Constructed wetlands are artificial environments that simulate natural wetlands. They are widely used because of their simple construction, operation and maintenance, and landscape effects. However, after long-term use, artificial wetlands may become clogged with fillers, resulting in reduced water flow capacity and failure to achieve the designed treatment effect and water volume. The wetlands need to be shut down for maintenance, and fillers need to be replaced or plowed.

[0003] At present, when replacing fillers, the planting soil layer and the fillers below are usually shoveled out manually in sequence. When shoveling out the planting soil layer, the floating plants planted on it need to be pulled out first or shoveled away together with the planting soil. When the filler is replaced, it needs to be replanted, which is not only time-consuming, labor-intensive and costly, but also destroys the established wetland ecology, requiring the entire wetland system to be restarted. Utility Model Content

[0004] The utility model aims to provide an artificial wetland water purification system with a simple structure, a filler structure capable of quickly replacing fillers, and a simple structure for maintaining the growth of floating plants in view of the above-mentioned deficiencies in the prior art.

[0005] The technical solution of the utility model is achieved as follows: an artificial wetland water purification system with a quickly replaceable filler structure comprises a purification pool, wherein the purification pool is provided with multiple layers of fillers, a first water inlet pipe is provided above the multiple layers of fillers at one end of the purification pool, and a first water outlet pipe is provided at the bottom of the other end of the purification pool.

[0006] A suspension bracket is arranged on the multi-layer filler through a lifting guide rod; a plurality of grid frames are distributed on the suspension bracket, at least two layers of planting baskets for loading cultivation soil are stacked in each grid frame, and floating plants are planted in the planting basket on the top layer.

[0007] In the above-mentioned artificial wetland water purification system with a quickly replaceable filler structure, the suspended support includes a lifting platform connected to a lifting guide rod through a sleeve, and a plurality of floating barrels are evenly distributed at the bottom of the lifting platform, and the floating barrels are installed through hoops.

[0008] The lifting platform is composed of a number of long plates staggered horizontally and vertically, and adjacent long plates cooperate to form a mounting square hole. A hook is provided on the inner wall of the mounting square hole, and a mounting flange for hanging on the hook is provided at the opening end of the grille frame.

[0009] In the above artificial wetland water purification system with a structure for quickly replacing fillers, a pre-filtering pool is provided on one side of the purification pool near the first water inlet pipe, and coarse filtering fillers are arranged in the pre-filtering pool; a second water inlet pipe is provided on the pre-filtering pool, and the water outlet end of the second water inlet pipe is located at the bottom of the coarse filtering fillers; the water inlet end of the first water inlet pipe is arranged on the side wall of the pre-filtering pool.

[0010] In the above artificial wetland water purification system with a structure for quickly replacing fillers, a water outlet pool is provided on one side of the purification pool near the first water outlet pipe, and filtering fillers are arranged in the water outlet pool; the water outlet of the first water outlet pipe is located above the filtering fillers, and a second water outlet pipe is provided on one side of the water outlet pool.

[0011] In the above artificial wetland water purification system with a structure for quickly replacing fillers, the planting basket includes a basket body, and a number of through holes are distributed on both the bottom and side walls of the basket body. On both side walls near the end of the opening end of the basket body, hand-holding holes are symmetrically provided; on the outer walls of the bottom and opening end of the basket body, stacked flanges are formed.

[0012] After the present utility model adopts the above structure, floating plants are planted in the planting basket. When multiple layers of fillers are blocked and need to be replaced, taking out the entire planting basket can effectively keep the floating plants and the planting soil intact. And compared with the traditional manual shoveling of soil, it can quickly take out the planting soil layer, effectively reduce the workload, improve the filler replacement efficiency, and maintain the original wetland ecosystem.

Detailed Embodiments

[0018] See also Figures 1-3 As shown, the utility model is an artificial wetland water purification system with a rapidly replaceable filler structure, comprising a purification pool 1, wherein a multi-layer filler 2 is arranged in the purification pool 1, a first water inlet pipe 3 is arranged above the multi-layer filler 2 at one end of the purification pool 1, and a first water outlet pipe 4 is arranged at the bottom of the other end of the purification pool 1. The multi-layer filler is a 2-4 mm gravel layer, a 4-8 mm gravel layer, and a 10-15 mm crushed stone layer from top to bottom, and the first water inlet pipe and the first water outlet pipe are arranged in a top-in and bottom-out manner so that the sewage is fully in contact with the multi-layer filler to remove impurities.

[0019] A suspension bracket 6 is provided on the multi-layer filler 2 through a lifting guide rod 5; a plurality of grid frames 7 are distributed on the suspension bracket 6, and at least two layers of planting baskets 8 for loading cultivation soil are stacked in each grid frame 7, and floating plants are planted in the topmost planting basket 8. The floating plants are planted in the planting baskets, and when the multi-layer filler is blocked and needs to be replaced, the planting baskets are taken out as a whole to effectively keep the floating plants and the planting soil intact, and the planting soil layer can be quickly taken out compared to the traditional manual shoveling, which can effectively reduce the workload, improve the efficiency of filler replacement, and maintain the original wetland ecosystem.

[0020] When the planting basket is taken out, the overall weight is reduced and the suspension bracket will rise accordingly, making it easy to remove the suspension bracket to clean the multiple layers of filler underneath.

[0021] In this embodiment, the suspension support 6 includes a lifting platform 6a connected to the lifting guide rod 5 through a sleeve, and a plurality of floating barrels 6b are evenly distributed at the bottom of the lifting platform 6a. The floating barrels 6b are installed through a hoop 6c.

[0022] The lifting platform 6a is composed of a number of long plates staggered horizontally and vertically, and the adjacent long plates cooperate to form a mounting square hole 6d. A hook 6e is provided on the inner wall of the mounting square hole 6d, and the opening end of the grille frame 7 is provided with a mounting flange 6f for hanging on the hook 6e. Corresponding quick-lock components are provided at the joints of each long plate for fixing, which is easy for a person skilled in the art to think of and will not be described here. After adopting the above structure, the lifting platform and the grille frame can be quickly disassembled and assembled. When all the planting baskets are taken out, the suspension bracket and the grille frame can be quickly removed to facilitate the cleaning of the multiple layers of filler below.

[0023] In this embodiment, a pre-filtering tank 9 is provided on one side of the purification tank 1 where the first water inlet pipe 3 is located, and a coarse filtering filler 10 is arranged in the pre-filtering tank 9; a second water inlet pipe 11 is provided on the pre-filtering tank 9, and the water outlet end of the second water inlet pipe 11 is located at the bottom of the coarse filtering filler 10; the water inlet end of the first water inlet pipe 3 is arranged on the side wall of the pre-filtering tank 9. The coarse filtering filler is made of cobblestones with a particle size of 25-40 mm. The relatively large impurities in the sewage are initially filtered by the coarse filtering filler, reducing the large-volume impurities entering the purification tank and effectively reducing the occurrence of blockage of multiple layers of fillers.

[0024] In this embodiment, an outlet tank 12 is provided on one side of the purification tank 1 where the first water outlet pipe 4 is located, and a filtering filler 13 is arranged in the outlet tank 12; the water outlet of the first water outlet pipe 4 is located above the filtering filler 13, and a second water outlet pipe 14 is provided on one side of the outlet tank 12. The filtering filler is made of cobblestones with a particle size of 25-40 mm. Before the water outlet, the purified water after purification is filtered again by the filtering filler to prevent the purified water from discharging with a small amount of gravel or plant stems and leaves in the purification tank.

[0025] In this embodiment, the planting basket 8 includes a basket body 8a, and a number of through holes 8b are distributed on both the bottom and the side wall of the basket body 8a. Hand-gripping holes 8c are symmetrically arranged on both side walls near the end of the opening end of the basket body 8a; stacked flanges 8d are formed on the outer walls of the bottom and the opening end of the basket body 8a. By setting the stacked flanges, the contact area between the upper and lower planting baskets is increased, facilitating the stacked storage of the planting baskets.

[0026] During operation, the planting baskets loaded with planting soil are stacked and placed in each grid frame, and then floating aquatic plants are planted in the uppermost planting basket. The sewage enters the pre-filtering tank through the second water inlet pipe to remove large-volume impurities, and then overflows into the purification tank through the first water inlet pipe. The impurities in the sewage are filtered by multiple fillers and decomposed by the floating aquatic plants. The purified water after purification is discharged into the outlet tank through the first water outlet pipe, and after being filtered again by the filtering filler, it overflows and is discharged through the second water outlet pipe.
