Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically a water ecological restoration and treatment device. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, significant threats have been posed to the ecological environment and human health. Currently, common water remediation methods mainly include physical, chemical, and biological methods. Physical methods remove suspended solids from water through sedimentation and filtration, but are difficult to effectively treat dissolved pollutants and nutrients. Chemical methods utilize chemical agents for oxidation, reduction, and coagulation reactions, which can rapidly reduce pollutant concentrations but are prone to introducing secondary pollution. Traditional biological methods rely on microorganisms to degrade pollutants, but when treating complex polluted water bodies, they suffer from low treatment efficiency and the susceptibility of microorganisms to environmental factors.

[0003] However, existing water body ecological restoration and treatment devices often cannot simultaneously address the removal of multiple pollutants and the synergistic restoration of the ecosystem. For example, some devices lack long-term treatment mechanisms for nutrients such as nitrogen and phosphorus in the water, leading to excessive algae growth and eutrophication. Some devices fail to create a diverse microenvironment suitable for microbial survival, resulting in insufficient degradation of organic matter and ammonia nitrogen. Furthermore, some devices have imperfect physical filtration systems that cannot effectively intercept colloids and fine particulate matter, affecting the quality of the effluent.

[0004] To address these issues, we have provided a water body ecological restoration and treatment device. Utility Model Content

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a water body ecological restoration and treatment device, including a sedimentation tank, wherein a hydrolysis tank and a wetland tank are sequentially arranged on the side of the sedimentation tank;

[0009] The wetland pond contains, from top to bottom, a wetland water layer, a wetland plant layer, a sand layer, a gravel layer, and a pebble layer.

[0010] The wetland pool is provided with an inlet and an outlet on both sides, with the inlet located at the side end of the wetland water layer and the outlet located at the side end of the pebble layer.

[0011] The drainage outlet of the wetland pond is connected to a drainage frame, and a filter plate is installed inside the drainage outlet. A water pump is connected to the side of the drainage frame.

[0015] Furthermore, the wetland pool is connected to a flow guide plate, which is inclined and has a lower end near the drain outlet. A layer of pebbles is laid on the flow guide plate.

[0016] Furthermore, the height of the water inlet of the No. 3 water pump is located in the middle of the sedimentation tank, and a filter frame is connected inside the sedimentation tank, with the water inlet of the No. 3 water pump located inside the filter frame.

[0017] Furthermore, a sewage pipe is provided at the side end of the sedimentation tank, and an electric gate is installed inside the sewage pipe. The gate consists of an electric telescopic rod and a gate plate, with the gate plate slidably connected inside the sewage pipe.

[0021] (iii) Beneficial effects:

[0022] Compared with existing technologies, this water body ecological restoration and treatment device has the following beneficial effects:

[0023] I. This water body ecological restoration and treatment device, through the setting of a wetland pond, allows water to enter the wetland pond sequentially through a sedimentation tank and a hydrolysis tank. Within the wetland pond, the water passes through a wetland plant layer, a sand layer, a gravel layer, and a pebble layer. The wetland plant layer: plant roots can block suspended solids, and aquatic plants absorb nutrients such as nitrogen and phosphorus through their roots, inhibiting algae growth; the aerobic and anaerobic microenvironment around the plant roots provides a living space for microorganisms, promoting the degradation of organic matter and ammonia nitrogen. The sand, gravel, and pebble layers: form a physical filtration system from fine to coarse, which can intercept colloids, fine particulate matter, and some microorganisms, further purifying the water quality. It effectively eliminates or reduces water pollution, enhances water quality, improves the oxygen-deficient state of the water body, increases water activity, and helps maintain the balance of the wetland ecosystem.

[0024] II. This water body ecological restoration and treatment device is equipped with a stirring motor and stirring rod in the sedimentation tank. When the stirring motor is started, it drives the stirring rod to rotate and stir the water. Stirring can accelerate the diffusion of the agent, so that the agent can fully contact the pollutants, improve the coagulation effect, reduce the treatment load of the subsequent hydrolysis tank and wetland tank, and accelerate the coagulation of fine suspended solids in the water into larger flocs, thereby increasing the settling speed, thus strengthening the sedimentation process and improving the removal efficiency of suspended solids.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a water body ecological restoration and treatment device, including a sedimentation tank 1. The sedimentation tank 1 removes larger suspended solids, silt and some organic matter from the water body through gravity sedimentation, reducing the turbidity of the water body and reducing the load on subsequent treatment. A hydrolysis tank 2 and a wetland tank 3 are arranged sequentially on the side of the sedimentation tank 1. The hydrolysis tank 2 decomposes large organic molecules into small molecules through the action of anaerobic microorganisms, improving the biodegradability of the water body. A No. 4 water pump 8 is arranged on the side of the sedimentation tank 1. The pumping end of the No. 4 water pump 8 is connected to the water body to be purified, and the outlet end is connected to the sedimentation tank 1. The No. 4 water pump 8 can pump the water body to be purified into the sedimentation tank 1.

[0034] A No. 3 water pump 7 is installed between sedimentation tank 1 and hydrolysis tank 2. The pump 7 is connected to the sedimentation tank 1 at its pumping end and to the hydrolysis tank 2 at its outlet end. The pump 7 is used to pump water from sedimentation tank 1 into hydrolysis tank 2. A No. 2 water pump 6 is installed between hydrolysis tank 2 and wetland tank 3. The pump 6 is connected to the hydrolysis tank 2 at its pumping end and to the inlet of wetland tank 3 at its outlet end. The pump 6 is used to pump water from hydrolysis tank 2 into wetland tank 3.

[0035] The pump 7 has its pump inlet located in the middle of the sedimentation tank 1, which effectively reduces the adsorption of sediment. A filter frame 10 is connected inside the sedimentation tank 1, and the pump inlet of the pump 7 is located inside the filter frame 10. The filter frame 10 is used to filter and block flocculent suspended matter in the water. A drain pipe 11 is provided on the side of the sedimentation tank 1 to discharge sediment from the sedimentation tank 1. An electric gate 12 is installed inside the drain pipe 11, which consists of an electric telescopic rod and a gate plate. The gate plate is slidably connected inside the drain pipe 11, and a sealing strip is provided between the two.

[0036] Multiple mounting frames 13 are connected to the upper end of the sedimentation tank 1. Rectangular grooves are opened inside the mounting frames 13, and mounting plates 14 are installed inside the mounting frames 13. The mounting frames 13 are used to install and constrain the mounting plates 14. The mounting plates 14 are connected to handles so that they can be easily disassembled, making it convenient for cleaning personnel to clean the inside of the sedimentation tank 1 through the rectangular grooves of the mounting frames 13. A chemical dosing port 15 is opened inside the mounting plates 14, and a cover plate is rotatably connected to the chemical dosing port 15. A handle is connected to the cover plate. A stirring motor 16 is connected to the middle mounting plate 14, and a stirring rod 17 is also rotatably connected inside the mounting plate 14. The stirring rod 17 is located inside the sedimentation tank 1. The drive end of the stirring motor 16 is connected to the stirring rod 17. When the stirring motor 16 is started, it will drive the stirring rod 17 to rotate, thereby stirring the water in the sedimentation tank 1, accelerating the contact between the sedimentation agent and pollutants, and improving the coagulation effect.

[0037] The wetland pond 3 contains, from top to bottom, a wetland water layer 301, a wetland plant layer 302, a sand layer 303, a gravel layer 304, and a pebble layer 305. Aquatic plants are planted in the wetland plant layer 302, which absorb nutrients such as nitrogen and phosphorus through their roots, inhibiting algae growth. The aerobic and anaerobic microenvironment around the plant roots provides a living space for microorganisms, promoting the degradation of organic matter and ammonia nitrogen. In addition, the plant roots can block some suspended solids, and the biofilm on the surface of the roots can adsorb pollutants. The sand layer 303, gravel layer 304, and pebble layer 305 form a physical filtration system from fine to coarse, which can intercept colloids, fine particulate matter, and some microorganisms, further purifying the water quality.

[0038] The wetland pond 3 has an inlet and an outlet on both sides. The inlet is located at the side of the wetland water layer 301, and the outlet is located at the side of the pebble layer 305. The outlet of the wetland pond 3 is connected to a drainage frame 4. A filter plate is installed in the outlet. The filter plate is used to prevent pebbles in the pebble layer 305 from entering the drainage frame 4. A water pump 5 is connected to the side of the drainage frame 4 to accelerate the water flow.

[0039] The wetland pool 3 is connected to a guide plate 9. The guide plate 9 is set at an angle, with the end near the drain outlet being the lower end. The pebble layer 305 is laid on the guide plate 9, so that the water can flow along the guide plate 9 into the drain frame 4.

[0040] Working principle: When in use, the No. 4 water pump 8 pumps water into the sedimentation tank 1, and adds coagulant into the sedimentation tank 1 through the dosing port 15, so that the fine suspended solids in the water are agglomerated into large flocs, which can settle the suspended solids. During this process, the stirring motor 16 starts and drives the stirring rod 17 to rotate, which accelerates the diffusion of the agent and makes the agent fully contact the pollutants, thereby improving the coagulation effect.

[0041] Pump 7 is started to pump the water in the middle layer of sedimentation tank 1 into hydrolysis tank 2 to improve the biodegradability of the water. During the pumping, filter frame 10 can effectively block the flocculent suspended matter in the water from passing through.

[0042] Pump 6 is activated to pump water from hydrolysis tank 2 into wetland tank 3. The water will pass through wetland plant layer 302, sand layer 303, gravel layer 304, and pebble layer 305 in wetland tank 3. Aquatic plants are planted in wetland plant layer 302. They absorb nutrients such as nitrogen and phosphorus through their roots, inhibiting algae growth. The aerobic and anaerobic microenvironment around the plant roots provides a living space for microorganisms, promoting the degradation of organic matter and ammonia nitrogen, thereby improving the oxygen-deficient state of the water and increasing the activity of the water. In addition, the plant roots can block some suspended solids. Sand layer 303, gravel layer 304, and pebble layer 305 form a physical filtration system from fine to coarse, which can intercept colloids, fine particles, and some microorganisms, further purifying the water quality. Finally, the purified water will flow into drainage frame 4 and be discharged by pump 5.
