Description

Technical Field

[0001] This utility model relates to the field of ecological restoration, specifically to an ecological water filtration pond for water ecological restoration. Background Technology

[0002] In the current field of water environment management, with the acceleration of industrialization and urbanization, water pollution problems are becoming increasingly serious. Eutrophication, heavy metal pollution, and the accumulation of organic pollutants are frequent occurrences, seriously threatening human health and the balance of ecosystems. Traditional water treatment methods, such as chemical precipitation and activated sludge processes, can remove pollutants from water to a certain extent, but they are often accompanied by high energy consumption, secondary pollution, and ecological damage. Therefore, developing a water treatment technology that can efficiently purify water while maintaining or restoring the health of aquatic ecosystems and enhancing the self-repairing capacity of water bodies is particularly important. Ecological filtration ponds, as a green purification system combining ecological principles and water treatment technology, are gradually becoming a research hotspot in the field of water ecological restoration due to their advantages such as low cost, low maintenance, and environmental friendliness.

[0003] However, existing ecological water filtration pond designs face multiple challenges: first, the purification efficiency is limited, especially for the removal of pollutants such as recalcitrant organic matter and heavy metals; second, the system stability is insufficient, and it is easily affected by seasonal changes, water quality fluctuations, and other factors; and third, the operation and maintenance costs are high, requiring regular cleaning, replacement of filter media, and equipment maintenance.

[0004] Therefore, an ecological filtration pond for water ecological restoration is proposed. Utility Model Content

A sludge discharge pipe is fixedly installed at the bottom of the sludge collection trough. The lower side of the ecological water filter pool is provided with a water outlet pipe, and the upper surface of the water outlet pipe is connected to a detection device.

[0008] Preferably, the water turbine frame is equipped with an adsorption filter to enhance the water purification capacity. A solar panel is fixedly installed on the top of the water turbine frame to collect solar energy and convert it into electrical energy. A rotating shaft is fixedly installed inside the water turbine frame, and the rotating shaft is powered by the solar panel.

[0009] Preferably, the bottom ends of the coarse filter layer, the fine filter layer, and the biofilm layer are all provided with porous baffles, and a plant layer is planted on the porous baffles between the coarse filter layer and the fine filter layer. The plant layer consists of emergent plants, floating plants, and submerged plants.

[0010] Preferably, the coarse filter layer uses a layer of stones or ceramsite with a particle size greater than 5 mm to initially trap large particles and suspended solids. The fine filter layer is located below the coarse filter layer and uses a layer of activated carbon or zeolite with a particle size less than 1 mm to deeply trap microparticles and dissolved substances. The biofilm layer is located below the fine filter layer and uses biological ceramsite as the filter media to remove dissolved organic matter, nitrogen, phosphorus and other pollutants from the water through biodegradation.

[0011] Preferably, the aeration device includes a motor, a coupling, fan blades, a fixed column, an aeration pipe, an air inlet pipe, and a blower. The motor is fixedly mounted on a fixed block inside the ecological water filter tank. The fan blades are fixedly connected to the output shaft of the motor via the coupling. The surface of the fan blades is provided with through holes. The fixed column is fixedly mounted at the lower end of the fan blades. The blower is fixedly mounted outside the ecological water filter tank. An air inlet pipe is fixedly mounted at the output end of the blower. One end of the aeration pipe is fixedly connected to one end of the air inlet pipe, and the aeration pipe extends into the interior of the ecological water filter tank. This is used to evenly inject the airflow generated by the blower into the water in the form of tiny bubbles, thereby increasing the dissolved oxygen content in the water.

[0012] Furthermore, the ultraviolet sterilization device includes an inlet, an outlet, a pipe component, and an installation component. The pipe component is fixedly installed inside the ecological water filtration tank. The pipe component is equipped with a long strip-shaped ultraviolet lamp. The installation component is detachably installed on the pipe component through a threaded connection. The installation component is equipped with a power supply component. The inlet is located at the top of the pipe component, and the outlet is located on the side wall of the pipe component.

[0013] Preferably, the detection device includes a display screen, a control panel, a processor, and a probe.

The processor is electrically connected to the probe and the display screen, and the processor is electrically connected to the control panel.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention achieves comprehensive removal of particulate matter, organic matter, heavy metal ions, and pathogenic microorganisms of different sizes from water by constructing a multi-layered purification structure including a pretreatment layer, a coarse filtration layer, a fine filtration layer, a biofilm layer, an aeration layer, and a disinfection layer. The pretreatment layer effectively blocks and intercepts floating debris in the wastewater through a water turbine and a screen. The coarse filtration layer initially intercepts large particles. The fine filtration layer deeply traps fine particles and dissolved organic matter, further improving water quality. The biofilm layer utilizes microbial degradation to remove dissolved organic matter, nitrogen, phosphorus, and other pollutants from the water, promoting the natural purification process. Simultaneously, the water... Nutrients are absorbed by aquatic plants in different parts such as roots, stems, and leaves, achieving the purpose of purifying water quality. The aeration device in the aeration layer uses a motor to drive the fan blades to rotate, generating a large number of small and uniform bubbles, which effectively increases the dissolved oxygen content in the water. This not only promotes the reproduction and activity of aerobic microorganisms in the water and enhances the self-purification capacity of the water, but also improves the overall purification efficiency. The disinfection layer effectively kills pathogenic microorganisms in the water through ultraviolet light irradiation, ensuring the safety of the effluent. This multi-level and multi-functional purification system significantly improves water quality and provides strong support for aquatic ecological restoration.

[0015] This invention's aeration device consists of two layers, combining blower aeration and mechanical aeration. When the gas from the blower is ejected from the aeration pipe's vents, the initial aeration effect is achieved. As the gas rises to the fan blades, a motor drives the blades to rotate, resulting in secondary aeration that breaks down large bubbles into smaller ones, effectively increasing the dissolved oxygen content in the water. Gas discharged from the fan vents rises directly, enhancing the aerobic reproduction of aerobic bacteria. This highly efficient aeration device not only promotes the reproduction and activity of aerobic microorganisms in the water but also enhances the water's self-purification capacity, creating favorable conditions for the restoration of the aquatic ecosystem.

[0016] This invention features a detection device installed on the water outlet pipe, which can monitor various indicators of the water quality in real time, such as dissolved oxygen content, turbidity, and pH value. The monitoring data is displayed on a screen in real time, allowing users to understand the water quality status promptly. Users can also set and operate the device through the control panel. This water quality monitoring not only improves the accuracy of water quality management but also provides users with a convenient operating experience, which helps to achieve refined management of water ecological restoration.
