Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an anti-clogging constructed wetland wastewater treatment system. Background Technology

[0002] Constructed wetland wastewater treatment is an ecological engineering technology that purifies wastewater by simulating natural wetland ecosystems and utilizing the synergistic effects of soil, plants, and microorganisms. It features low construction costs, simple operation and maintenance, and environmental friendliness. It forms an ecosystem through artificially constructed bed of packing materials (such as gravel, activated biological filter media, and substrates) and specific aquatic plants (such as reeds and cattails), removing pollutants through a triple process of physical (filtration, sedimentation), chemical (oxidation-reduction), and biological (microbial decomposition, plant absorption).

[0003] In current constructed wetland wastewater treatment systems, plants are usually planted directly on the packing bed. This method has the following problems: on the one hand, plant residues (roots, stems, and leaves) rot in the packing bed, clogging the substrate pores and reducing the hydraulic conductivity; on the other hand, manually harvesting plant residues requires emptying the wetland and stopping the bed operation, which is labor-intensive and costly. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-clogging constructed wetland wastewater treatment system, so as to reduce the possibility of substrate clogging and improve the convenience of harvesting plant residues.

[0005] This utility model solves the above problems through the following technical means:

[0006] A clog-resistant constructed wetland wastewater treatment system includes a packing bed and a planting float floating above the packing bed. The planting float has multiple planting holes. A retrieval net is laid on the top surface of the planting float, and a retrieval net winding mechanism is provided on one side of the planting float.

[0007] Furthermore, an ultrasonic vibrator is provided at the bottom of the packing bed.

[0008] Furthermore, multiple ultrasonic vibrators are evenly arranged at the bottom of the packing bed.

[0009] Furthermore, the planting float is provided with a buoyancy adjustment cavity.

[0010] Furthermore, the mesh size of the salvage net is 1-5 mm.

[0011] Furthermore, the frequency of the ultrasonic vibrator is 20-40 kHz.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The anti-clogging constructed wetland wastewater treatment system of this application includes a packing bed and a planting float floating above the packing bed. The planting float has multiple planting holes. A retrieval net is laid on the top surface of the planting float, and a retrieval net winding mechanism is provided on one side of the planting float.

Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing and simplifying the description of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0019] like Figure 1As shown, this embodiment provides an anti-clogging constructed wetland wastewater treatment system, including a packing bed 1 and a planting float 2 floating above the packing bed. The planting float 2 has multiple planting holes. A retrieval net 3 is laid on the top surface of the planting float 2, and a retrieval net winding mechanism 4 is provided on one side of the planting float 2. The mesh size of the retrieval net is 1-5 mm. In this embodiment, the retrieval net winding mechanism includes a winding shaft and a drive mechanism for driving the winding shaft to rotate. One side of the retrieval net is wound around the winding shaft.

[0020] During implementation, the plant roots are wrapped in the net and planted through the planting hole. The roots absorb nutrients from the filling bed to grow. Rotten plant branches and leaves can be caught in the net during the growth process. When it is time to harvest the plants, the net can be lifted, wound and gathered by the net winding mechanism. Then the plant debris caught in the net can be cleaned up.

[0021] In summary, the artificial wetland wastewater treatment system of this application allows plants to be planted in a floating state. Plant residues can be intercepted and retrieved using a retrieval net. Therefore, the possibility of plant residues clogging the substrate pores is greatly reduced, and the convenience of harvesting plant residues is effectively improved.

[0022] As a further improvement to the above technical solution, an ultrasonic vibrator 6 is provided at the bottom of the packing bed, and the frequency of the ultrasonic vibrator is 20-40 kHz. Preferably, multiple ultrasonic vibrators are evenly arranged at the bottom of the packing bed. During operation, the ultrasonic vibrators are intermittently activated to intermittently cavitate and peel off the biofilm and loosen the root system through ultrasonic vibration.

[0023] As a further improvement to the above technical solution, the planting float is provided with a buoyancy adjustment cavity 5. By injecting or draining water into the buoyancy adjustment cavity, the overall raising and lowering of the planting float can be achieved, thereby adjusting the contact between the plant roots and the packing bed.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
