Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a vertical ecological sewage purification device. Background Art

[0002] Since my country's reform and opening up, the economy has developed rapidly and people's living standards have improved. At the same time, ecological destruction and environmental pollution problems have occurred frequently. The "development first, governance later" model has been completely denied. The amount of sewage brought about by development has increased sharply. Due to the limited sewage treatment capacity, a large amount of untreated sewage has been discharged into natural water bodies, causing water pollution.

[0003] Existing sewage treatment technologies generally target domestic water use in urban areas. However, the influent conditions of sewage treatment plants are significantly correlated with treatment effectiveness, often requiring further treatment, such as the addition of carbon sources. This increases costs and leads to inconsistent results. Furthermore, existing sewage treatment technologies suffer from high energy consumption and maintenance costs. Furthermore, sewage treatment equipment is complex and sometimes occupies a large area, generating exhaust and noise that severely impacts the lives of surrounding residents, further detracting from the aesthetic appeal of the landscape. Summary of the Invention

[0004] In response to the deficiencies in the existing technology, the utility model provides a vertical ecological sewage purification device that meets the requirements of a small footprint, beautiful greening effects, effective sewage purification, low maintenance costs, and can be applied to sewage ecological treatment devices in a variety of scenarios.

[0005] To achieve the above objectives, the present invention provides a vertical ecological sewage purification device comprising a sewage tank with an overflow port at the top, an inlet pipe at the bottom, and multiple layers of annular overflow troughs arranged in a stepped pattern from bottom to top. Sewage flowing out of the overflow port flows sequentially through each overflow trough from top to bottom, with an outlet pipe provided on the sidewall of the bottom overflow trough.

[0006] Preferably, the sewage tank consists of a sedimentation area in the upper half and a collection area in the lower half; the central area at the bottom of the sedimentation area is connected to the central area at the top of the collection area, the upper part of the sedimentation area is an inverted funnel shape, the middle part is rectangular, and the lower part is funnel-shaped; the collection area is a rectangular box.

[0009] Preferably, a planting grid is mounted on the rectangular ring bottom plate. The planting grid is composed of multiple grid units. Various aquatic plants, such as pectin, cattail, reed, and Phragmites australis, can be planted within these grid units. Wastewater is purified by absorption and adsorption by the roots of the various aquatic plants in the overflow trough from top to bottom. The planting grid is woven from PVC material and can be replaced entirely after the plants die.

[0010] Preferably, the top of the outer rectangular frame plate is a tooth-shaped structure, which slows down the flow rate of sewage overflowing from the overflow trough.

[0011] Preferably, a slag discharge pipe penetrating the overflow trough is provided at the bottom of the side wall of the sewage tank, and a plug is provided at the pipe opening of the slag discharge pipe.

[0031] Example

[0032] like Figures 1 to 3The vertical ecological sewage purification device shown includes a sewage tank 1, which consists of a sedimentation area 12 in the upper half and a collection area 13 in the lower half; the central area at the bottom of the sedimentation area 12 is connected to the central area at the top of the collection area 13, the upper part of the sedimentation area 12 is an inverted funnel shape, the middle part is rectangular, and the lower part is funnel-shaped; the collection area 13 is a rectangular box.

[0033] An overflow port 11 is provided at the top of the sewage tank 1, and an inlet pipe 2 is provided at the bottom. A filter screen 111 is provided at the overflow port 11. The inlet pipe 2 extends to the top area of ​​the sewage tank 1, and a lifting pump 22 is provided on the inlet pipe 2. A plurality of annular overflow troughs 3 are provided on the outside of the sewage tank 1. The overflow troughs 3 are arranged in a stepped manner from top to bottom. The sewage flowing out of the overflow port 11 passes through each overflow trough 3 in sequence from top to bottom. An outlet pipe 35 is provided on the side wall of the overflow trough 3 at the bottom layer. The overflow trough 3 includes an outer rectangular frame plate 31, an inner rectangular frame plate 32 is provided inside the outer rectangular frame plate 31, and a rectangular ring bottom plate 33 is provided between the outer rectangular frame plate 31 and the inner rectangular frame plate 32. A planting grille 34 is provided on the rectangular ring bottom plate 33, and the planting grille 34 is spliced ​​together by a plurality of grille units 341. The top of the outer rectangular frame plate 31 is a tooth-like structure. The bottom of the side wall of the sewage tank 1 is provided with a slag discharge pipe 14 that passes through the overflow trough 3. The pipe opening of the slag discharge pipe 14 is provided with a plug. A support system 4 is provided between the sewage tank 1 and the overflow trough 3. The support system 4 is formed by connecting multiple stainless steel pipes.

[0034] The following describes the process flow of the utility model when it works:

[0035] The sewage to be treated is transported to the sewage tank 1 through the water inlet pipe 2, and then the sewage in the water inlet pipe 2 is transported to the top area of ​​the sedimentation area 12 of the sewage tank 1 through the lifting pump 22. The silt and sediment in the sewage are deposited to the bottom of the collection area 13 through the sedimentation area 12. The sewage at the top of the sewage tank 1 overflows from the edge of the overflow port 11 and flows down along the upper outer wall of the sedimentation area 12 to the overflow trough 3. Various aquatic plants such as duckweed, cattail, reed, and reed are planted in the overflow trough 3. After being absorbed by the roots, the sewage overflows through the tooth structure on the top of the outer rectangular frame plate 31 and flows along the outer wall of the overflow trough 3 to the adjacent overflow trough 3 directly below. Similarly, the sewage passes through multiple stepped overflow troughs 3 from top to bottom. Finally, the purified sewage flows into the natural water body from the outlet pipe 35 of the overflow trough 3 at the bottom. When the sediment in the collection area 13 at the bottom of the sewage tank 1 needs to be cleaned, the plug in the slag discharge pipe 14 is taken out, and the staff pours clean water from the sewage tank to clean and discharge the sediment through the slag discharge pipe 14.
