Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment, specifically relating to a floating device for underwater sediment treatment. Background Technology

[0002] Organic pollutants in rivers and lakes mainly originate from industrial wastewater discharge, domestic wastewater discharge, agricultural drainage, atmospheric deposition, metabolic products and decomposition products of aquatic plants, microorganisms, and animals. These sources of organic matter have a significant impact on the water quality and aquatic ecosystem of rivers and lakes.

[0003] River and lake sediments are accumulation and storage sites for various pollutants. Over time, pollutants such as heavy metals, organic matter, nitrogen, and phosphorus accumulated in the sediment can be released back into the water under certain conditions, becoming an important source of endogenous pollution and leading to water quality deterioration.

[0004] Whether it's river and lake water pollution control or bottom sediment treatment, both are of great significance for restoring the aquatic ecosystem, improving water quality, and promoting sustainable development.

[0005] Currently, using microbial agents to treat rivers, lakes, and sediment is an effective method. Methods of application in rivers and lakes include: workers using tools (boats, etc.) to directly apply the microbial agents to designated areas, which is relatively simple to operate but inefficient and difficult to guarantee uniformity; or using specialized application equipment (such as spray trucks) for large-area, more uniform application, which can improve efficiency, but the equipment cost is high and the operation requirements are also high; or setting up specific application points in the rivers and lakes, allowing for continuous release of the microbial agents at fixed locations, enabling precise control of the application location, but the coverage area is relatively limited.

[0006] In addition, after microbial agents are applied to rivers and lakes, a large number of microorganisms may die due to unsuitable water environment (such as unsatisfactory water temperature and oxygen content), thus failing to play an effective role. Many microorganisms in microbial agents used for river and lake management are aerobic bacteria, which can only carry out normal respiration in the presence of oxygen. Therefore, dissolved oxygen is an important indicator.

[0007] The existing water pollution treatment devices have the following disadvantages:

[0008] 1. Existing equipment cannot directly contact the bottom sediment at close range when applying microbial agents, resulting in poor treatment effects;

[0009] 2. After microbial agents are released into rivers and lakes, the external conditions for the agents to take effect are insufficient, especially the amount of dissolved oxygen is insufficient.

[0010] 3. Existing microbial agents are applied in a crude manner, resulting in poor effectiveness and limited treatment space and scope. Summary of the Invention

[0011] This invention provides a floating device for underwater sediment treatment, which solves the problems of poor treatment effect, small treatment space, and limited range of existing microbial agents.

The bottom of the microbial agent dispensing system is connected to the support base.

[0013] The float comprises a circular hollow body, an annular column, a cavity, an air pipe outlet, a fixed rope channel, a migration ring, and a ring connecting surface. The upper part of the circular hollow body is a raised annular column, on which a solar power generation panel is laid. The center of the annular column is a cavity, inside which an aeration fan is installed. The circular hollow body has two fixed rope channels on its edge and an air pipe outlet at its bottom center. The side of the circular hollow body has a ring connecting surface, on which the migration ring is installed for connection with an external migration device.

[0014] The microbial agent dispensing system includes a crossbar, a microbial dispensing bucket, an outer cylinder, a cross-shaped fixing plate, springs, a rotating motor, a three-bladed agitator, a bottom sediment agitator, a rotating shaft, and a fixing ring at the bottom of a fixing rope. The upper part of the outer cylinder is open with no holes in the cylinder wall, and the lower part has a cross-shaped fixing plate. The microbial dispensing bucket is placed inside the outer cylinder, and the upper part is blocked by the crossbar. Four springs are fixed on the upper part of the cross-shaped fixing plate, and a rotating motor is fixed at the center of the cross-shaped fixing plate. The lower part of the rotating motor is connected to the rotating shaft, and a three-bladed agitator and a bottom sediment agitator are fixed on the rotating shaft in sequence. The bottom sediment agitator is composed of a straight crossbar and multiple pointed claw nails. The microbial dispensing bucket is placed in the outer cylinder, and the fixing ring at the bottom of the fixing rope is fixedly connected to the upper outer side of the outer cylinder.

[0015] The microbial dispensing bucket is cylindrical, filled with microbial agents, and has a dispensing cylinder top cover. The lower part of the bucket, the bucket wall, and the dispensing cylinder top cover each have multiple drainage holes.

[0016] The support base includes support rods and a boat-shaped base. The top ends of the four support rods are fixedly connected to the lower edge of the outer cylinder of the microbial agent dispensing system, and the bottom ends are connected to the boat-shaped base, which is composed of two parallel arc-shaped rods.

[0017] The aeration system includes an aeration blower, an air pipe, a microporous aeration pipe, and a microporous aeration pipe holder. The aeration blower is installed inside the cavity of the float. The upper end of the air pipe is connected to the aeration blower through the air pipe outlet at the bottom of the float, and the lower end is connected to the microporous aeration pipe. The microporous aeration pipe is wrapped around the surface of the outer cylinder of the microbial agent dispensing system. Each layer of microporous aeration pipe is fixed to the surface of the outer cylinder with a microporous aeration pipe holder.

[0018] The fixing rope device includes a protective cover, a fixing rope receiving cavity, a barrier plate, a fixing rope, a rope fixing bolt, and a fixing rope waterproof connector. The protective cover is installed at the upper opening of the fixing rope channel of the float. The barrier plate is fixedly connected in the fixing rope channel. The fixing rope receiving cavity is located between the protective cover and the barrier plate. The rope fixing bolt is fixedly connected to the barrier plate. The fixing rope waterproof connector is installed at the central circular hole of the barrier plate. The upper part of the fixing rope is wrapped around the handle of the rope fixing bolt and passes through the fixing rope waterproof connector.

[0020] The advantages of this invention are its novel structure. It utilizes solar panels to generate electricity, powering the aeration blower and the lower rotating motor. The microbial agent is dissolved and diluted in water via the influent dispensing system, and the shaking effect generated by the water flow propels the agent downwards. This method is beneficial for centralized treatment of bottom sediment, saves energy, and slows down the dispensing speed, promoting economical use and long-term, large-area dispensing. It ensures that the microbial agent is concentrated at the bottom underwater and allows for repeated use of the dispensing tank. The three-blade agitator and the bottom sediment agitator complement each other. The microbial agent is thoroughly mixed with the surface water of the bottom sediment to induce a biochemical reaction. The microbial agent can simultaneously degrade the water in the upper space, the sludge, and the bottom sediment. The aeration method adopts a ring-shaped aeration method with microporous aeration pipes wrapped around the outer cylinder, which increases the aeration range and density, enhances the oxygen-rich environment of the water, and improves the sewage and bottom sediment treatment capacity of the microbial agent. The device is relocatable; minor moves can be achieved through wind and water flow impact, while major moves can be achieved through additional relocation devices, ensuring a large and wide dissemination range of the microbial agent.

[0036] Working principle

[0037] (1) Preparations before entering the water

[0038] To fill the microbial agent, remove the top cover 30202 of the microbial spreading tank 302. Lay a layer of water-soluble film (non-toxic and harmless material) around the bottom and sides of the microbial spreading tank 302, then pour in powdered or liquid microbial agent. Attach the water-soluble film to the bottom of the top cover 30202, and then tighten the top cover 30202 onto the microbial spreading tank 302. Place the microbial spreading tank 302 inside the outer cylinder 303, with four springs 305 at the bottom. The upper part of the microbial spreading tank 302 is contained within the outer cylinder 303 by a crossbar 301.

[0039] (2) Entering the water

[0040] Slowly lower the float 1 and the microbial dissemination system 3 into the water until the boat-shaped base 402 of the microbial dissemination system is close to the bottom. Adjust the fixing ropes 604 on both sides. The fixing ropes 604 are adjusted and fixed in length on the upper part of the barrier plate 603 by rope fixing bolts 605. The fixing method is as follows: wrap the fixing rope 604 around the handle 60502, pull back the push-pull bolt 60503, then press down the handle 60502 so that it is at the lower end of the push-pull bolt 60503, and then push out the push-pull bolt 60503 to fix the rope.

[0041] (3) Device operation

[0042] The aeration blower 501 and the rotating motor 306 are turned on in sequence, and air is sprayed out in all directions through the microporous aeration pipe 503, including downward spraying, to form an all-round oxygen-rich environment.

[0043] After the microbial dispensing tank 302 is immersed in water, the water-soluble film begins to dissolve. River and lake water flows into the microbial dispensing tank 302 from all sides, mixes with the microbial agent, and slowly flows out under the impact of external force. After the microbial agent flows down from the microbial dispensing tank 302, the three-bladed agitator 307 can fully mix it with the surface water of the bottom sediment, allowing the microbial agent to quickly adapt to the muddy water environment. The multiple sharp claws of the bottom sediment agitator 308 strongly agitate the bottom sediment through rotation, and the bottom sediment that rises to the surface comes into preferential contact with the microbial agent. With the help of oxygen and other factors, the microorganisms undergo degradation treatment. The loosened bottom sediment can continue to mix fully with the falling microbial agent again. This method can maximize the efficiency and utilization rate of the microbial agent.

[0044] (4) The device is relocatable. Small movements can be achieved by wind and water flow impact, while large movements can be achieved by additional relocation devices to ensure a large range and wide space for microbial agent dissemination;

[0045] The boat-shaped base 402 consists of two parallel arc-shaped rods. The arc-shaped base has a small and smooth contact area with the bottom mud, which is conducive to the movement of the float.

[0046] The device can be used not only for bottom sediment treatment, but also for wastewater treatment of upper water bodies through microbial agents and an oxygen-rich environment.
