Description

Technical Field

[0001] This utility model relates to the field of constructed wetlands, specifically a landscape-oriented constructed wetland. Background Technology

[0002] Constructed wetlands are artificially built and controlled wetland-like surfaces. Wastewater and sludge are systematically introduced onto these artificial wetlands, and the wastewater and sludge are treated through the synergistic physical, chemical, and biological processes of soil, artificial media, plants, and microorganisms during their directional flow. The mechanisms of action include adsorption, retention, filtration, oxidation-reduction, sedimentation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration and nutrient absorption, and the activity of various animals. Currently, constructed wetlands are widely used in residential wastewater treatment due to their high efficiency, environmental friendliness, and low cost.

[0003] Current constructed wetlands have poor wastewater treatment effects, and the treated water is stored in a collection tank in a static state, which will cause changes in water quality over a long period of time. Utility Model Content

[0004] The purpose of this invention is to provide a landscape-oriented artificial wetland to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a landscape-oriented artificial wetland, comprising a primary ecological pond, a permeable tank, and a first inlet connected to the primary ecological pond. The primary ecological pond contains a primary filter layer, with floating plants planted on top. Permeable tanks are located on both sides of the primary filter layer. A connecting groove is provided at the bottom of each permeable tank, and a deodorizing filter plate is installed on the inner side of the permeable tank, vertically connected to the connecting groove. A second inlet and a first outlet are respectively opened at both ends of the permeable tank. The second inlet is connected to the primary ecological pond and is higher than the height of the primary filter layer. The first outlet is lower than the height of the primary filter layer. The first outlet is connected to a secondary ecological pond, which includes an overflow pipe, a biological filler layer, a secondary filter layer, and a gravel filler layer. The biological filler layer is disposed on top of the secondary filter layer and the gravel filler layer, and aquatic vegetation is planted on its top.

[0006] Preferably, one end of the overflow pipe is connected to the first outlet, and the other end extends into the area between the biological packing layer and the secondary filter layer. Overflow holes are provided on the overflow pipe at intervals.

[0007] Preferably, a water collection area is provided at the bottom of the crushed stone filler layer, a water pump is provided in the water collection area, the output end of the water pump is connected to a water delivery pipe, the water delivery pipe passes through the secondary ecological pond and extends to the outside of the secondary ecological pond, and the water delivery pipe is connected to the advanced ecological pond.

[0008] Preferably, the advanced ecological pond includes a gravel filter layer and a fine particle filter membrane layer, with the gravel filter layer laid on the fine particle filter membrane layer, and a second outlet connected to the bottom of the advanced ecological pond.

[0009] Preferably, the floating plant is duckweed, and the aquatic vegetation is aquatic evergreen plants, with the planting height controlled between 0.8 and 1.2 meters.

[0010] Compared with existing technologies, the advantages of this utility model are: This utility model is simple and convenient, and easy to maintain. Compared with other traditional secondary biological treatment and deep sewage treatment technologies, artificial wetlands have more prominent advantages such as low investment, easy management, and high removal rate. At the same time, it avoids the defects of the original water landscape that must be cleaned and replaced in time. The biological filler, as the medium layer, mainly purifies sewage through the adsorption, retention, filtration, oxidation-reduction, sedimentation, microbial decomposition, and transformation of the biological filler. At the same time, the setting of gravel filter layer and fine particle filter membrane layer can improve the filtration and adsorption capacity and improve the purity of the output water.
