Description

Technical Field

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

[0002] Currently, most sewage treatment plants use a series of physical, chemical and biological treatment technologies to purify sewage, including sedimentation, filtration, disinfection and activated sludge methods, which are designed to remove suspended solids, organic matter, pathogens and some nutrients in sewage. However, even after these treatments, the discharged sewage still has a gap with the water quality standards of natural water bodies (such as lakes and rivers), especially in terms of nutrients (such as nitrogen and phosphorus), dissolved oxygen content, turbidity and microbial indicators.

[0003] Discharging treated wastewater directly into natural water bodies, especially in static or low-flow areas of lakes or rivers, can cause the following problems:

[0004] Local water quality deterioration: The difference in temperature, salinity or pollutant concentration between the discharged sewage and the surrounding water bodies may form water quality "hot spots" near the discharge port, affecting the ecological balance of the water body.

[0005] Sewage accumulation: Due to fluid mechanics factors, discharged sewage may accumulate at the discharge port, forming areas with high local pollutant concentrations, affecting the natural circulation and self-purification capacity of the water body. Utility Model Content

[0006] The main purpose of the utility model is to provide a sewage outlet purification device to solve the problems in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is: comprising a floating waterway arranged along the drainage pipe, one end of the floating waterway is fixed on the drainage pipe, and the other end is located in the center of the water body and is open, a plurality of water plant planting racks are arranged on the floating waterway, and an aeration pipe is arranged in the floating waterway;

[0008] Buoys are arranged on both sides of the floating waterway, and barrier membranes are arranged between the buoys. The water discharged from the drainage pipe moves in the barrier membrane, and a plurality of water plants are planted between the two buoys.

[0014] The utility model provides a purification device for sewage outlets, and the beneficial effects are as follows:

[0015] 1. Through the absorption of the roots of aquatic plants, the nutrient salts such as nitrogen and phosphorus in the water body can be effectively removed, reducing the risk of water eutrophication and avoiding the occurrence of algal bloom events. The tiny bubbles provided by the aeration pipe increase the dissolved oxygen content in the water body, promote the growth of aerobic microorganisms, accelerate the decomposition of organic matter, and improve the self-purification ability of the water body. The synergistic effect of aquatic plants and microorganisms helps to adsorb and precipitate suspended solids, reduce the turbidity of the water body, and improve the transparency.

[0024] As Figures 1 to 3 shown, a purification device for sewage outlets includes a float water channel 2 arranged along the drain pipe 1. One end of the float water channel 2 is fixed on the drain pipe 1, and the other end is located in the center of the water body and is open. A plurality of water plant planting racks 3 are provided on the float water channel 2, and an aeration pipe 4 is arranged in the float water channel 2;

[0025] Buoyancy floats 203 are provided on both sides of the float water channel 2, a barrier film 201 is arranged between the buoyancy floats 203, and the water discharged from the drain pipe 1 moves within the barrier film 201. A plurality of water plant planting racks 3 are arranged between the two buoyancy floats 203. The sewage discharged from the drain pipe 1 moves on the float water channel 2 to the center of the water body, and the sewage is purified by the aquatic plants planted on the water plant planting rack 3. Tiny bubbles are also generated in the sewage through the aeration pipe 4, and the tiny bubbles come into contact and mix with the sewage, thereby increasing the dissolved oxygen content of the sewage.

[0026] The float water channel 2 plays a role in guiding the water flow, ensuring that the sewage can flow along the set path to the center of the water body instead of being directly discharged into the environment, reducing the direct impact on the surrounding environment.

[0027] The aquatic plants on the water plant planting rack 3 absorb nutrients such as nitrogen and phosphorus pollutants in the water through their roots, which helps to reduce the eutrophication level of the water body and improve the water quality. The presence of the plants can also provide habitats for microorganisms, promoting the formation of microbial communities, and these microorganisms can further degrade organic matter and improve the self-purification ability of the water body.

[0028] The aeration pipe 4 releases tiny bubbles into the water, increasing the dissolved oxygen content in the water body. High dissolved oxygen is beneficial to the activities of aerobic microorganisms, accelerating the decomposition of organic matter, and at the same time inhibiting the generation of harmful gases that may be produced under anaerobic conditions. The contact between the tiny bubbles and the sewage also helps to remove volatile organic compounds and other gas pollutants in the water.

[0029] Preferably, arc plates 301 are fixedly provided at both ends of the planting cylinder 302 in the water plant planting rack 3. The arc plates 301 abut against the buoyancy floats 203 and are connected and fixed by locking bolts 303. Both ends of the planting cylinder 302 are fixed on the buoyancy floats 203 on both sides of the float water channel 2 through the arc plates 301, which can support the float water channel 2 and enable the planting cylinder 302 and the buoyancy floats 203 to change with the water level change, so that the planting cylinder 302 is always submerged in the water.

[0030] The arc plate 301 provides a firm connection between the planting cylinder 302 and the floating cylinder 203. Through the abutment and the fixation of the locking bolt 303, the structural integrity can be maintained even under the impact of water flow or the action of wind and waves.

[0031] The planting cylinder 302 is connected to the floating cylinder 203 through the arc plate 301, which means it can float with the floating cylinder. When the water level rises or falls, the entire system will adjust its height accordingly, ensuring that the planting cylinder is always below the water surface, guaranteeing sufficient contact between the roots of aquatic plants and the water body, and being beneficial to plant growth and the water purification process.

[0032] The use of the locking bolt 303 makes the installation and disassembly of the planting cylinder 302 simple and fast, facilitating maintenance and the replacement of plants. This also means that the types and quantities of aquatic plants can be flexibly adjusted according to different seasons or water quality conditions.

[0033] Preferably, a wooden core 202 is provided inside the floating cylinder 203, and the locking bolt 303 passes through the floating cylinder 203 and is threadedly connected to the wooden core 202. The connection between the arc plate 301 and the floating cylinder 203 is more stable and reliable.

[0034] The wooden core 202 has good tensile strength and high thread engagement ability, which can provide a stable threaded connection point for the locking bolt 303 and prevent the bolt from loosening or slipping in the floating cylinder.

[0035] Through the threaded connection between the locking bolt 303 and the wooden core 202, it can be ensured that the connection between the arc plate 301 and the floating cylinder 203 is more firm, improving the durability and reliability of the entire structure.

[0036] Using the wooden core 202 as an intermediate connecting piece can simplify the connection steps between the arc plate 301 and the floating cylinder 203, avoiding the complexity and possible failure risk of directly tapping threads on the floating cylinder material.

[0037] When it is necessary to adjust the position of the planting cylinder 302 or replace damaged components, by loosening the locking bolt 303, the arc plate 301 can be easily separated from the floating cylinder 203, and after maintenance, it can be tightened again, with simple operation.

[0038] Preferably, the aeration pipe 4 includes a main pipe and branch pipes. A plurality of branch pipes are horizontally arranged along the direction of the floating buoy water channel 2, and a plurality of aerators are provided on each branch pipe. The aerators are arranged obliquely along the water flow direction. The inclined arrangement method can accelerate the water circulation during the generation of microbubbles.

[0039] The horizontal arrangement of the branch pipes and the inclined arrangement of the aerators ensure the uniform distribution and directional movement of the bubbles. When the bubbles rise in the water, due to the inclined angle of the aerators, they will push the water flow to flow along the inclined direction, which not only increases the turbulence degree of the water body but also helps to improve the oxygen dissolution rate.

[0040] When the aerator is arranged obliquely, while generating microbubbles, due to the upward buoyancy of the bubbles and the natural flow of the water body, the flow velocity of the water body can be accelerated, which helps the sewage to come into full contact with oxygen, thereby improving the efficiency of dissolved oxygen.

[0041] The acceleration of the water flow and the increase in turbulence help to break the "gas exchange barrier" on the water surface, that is, a thin layer of calm water on the water surface, which will hinder the rapid exchange of gases. Through the oblique arrangement of the aerator, this barrier can be effectively overcome, promoting the faster dissolution of oxygen into the water.

[0042] Compared with the traditional vertical aeration method, the obliquely arranged aerator can utilize the natural power of the rising bubbles, reduce the additional energy demand, and at the same time achieve even exceed the same aeration effect.

[0043] Preferably, a blower is also provided, and the end of the main pipeline is connected to the outlet of the blower. The blower inhales the outside air, then compresses the air to a certain pressure through the internal impeller or other compression mechanisms, and then transports it to the aeration system through the main pipeline. The end of the main pipeline is directly connected to the outlet of the blower, so that a continuous and stable air flow can be ensured to enter the aeration system, providing sufficient air source for the aerator and generating a large number of microbubbles.

[0044] The output of the blower can be controlled by adjusting its rotation speed or valve opening, which means that the aeration volume can be precisely adjusted, and the aeration efficiency can be dynamically adjusted according to the needs of sewage treatment and the dissolved oxygen demand of the water body.

[0045] The selection and operating efficiency of the blower directly affect the energy consumption of the entire aeration system. An efficient blower can provide the required air flow and pressure with lower energy consumption, thereby reducing the operating cost.

[0046] Preferably, a plurality of planting holes are provided on the planting cylinder 302 for planting aquatic plants. The planting holes provide fixed points for the growth of aquatic plants. The roots of the plants can penetrate through these holes and extend into the water to absorb water and nutrients, while fixing the plants to prevent drifting due to water flow or wind. The size and spacing of the planting holes need to be carefully designed to ensure that each plant can obtain sufficient light, space and nutrients, avoid excessive competition between plants, and promote healthy growth.

[0047] Aquatic plants absorb nutrients such as nitrogen and phosphorus in the water through their roots, which helps to reduce the eutrophication level of the water body, reduce the risk of algal blooms, and thus improve the water quality. The plants on the planting cylinder provide additional habitats for the aquatic ecosystem, which can attract and support various aquatic organisms such as insects, fish and birds, increasing biodiversity.

[0048] The growth of aquatic plants also adds green elements to the water area landscape, beautifies the environment, and can also be used as on-site teaching materials for ecological education to help the public understand the process and importance of water purification. According to different water conditions and purification requirements, different types of aquatic plants can be planted on the planting cylinder 302, or the plant density can be adjusted to optimize the purification effect.

[0049] The above embodiments are only the preferred technical solutions of the present utility model and should not be regarded as limitations on the present utility model. The protection scope of the present utility model should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present utility model.
