[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] As attached Figures 1 to 3 A biological leaching device with real-time nutrient supply is shown, comprising a housing 1, which is made of a high-hardness metal material and plays a supporting and protective role. A feeding mechanism 2 is arranged on one side of the top of the housing 1. The arrangement of the feeding mechanism 2 makes the device highly adaptable to the environment, and can effectively cope with different climate and geological conditions whether it is used indoors or outdoors. A shunt pipe 3 is connected to one side of the feeding mechanism 2. The shunt pipe 3 can be made of a high-pressure seamless steel pipe or an ultra-low friction wear-resistant composite pipe. These materials can effectively resist the wear and corrosion problems that may be encountered during sludge transportation, and ensure the long-term stable operation of the pipeline;

[0023] A leaching pipe 4 is arranged on one side of the shunt pipe 3. There are three groups of leaching pipes 4, and the three groups of leaching pipes 4 are evenly arranged along the vertical direction of the shunt pipe 3. The surface of the leaching pipe 4 should be suitable for the attachment and growth of the biofilm. A material with a slightly rough surface can be selected or the surface can be specially treated to increase the contact area between the microorganism and the carrier, and promote the formation and stability of the biofilm. A water mist nozzle 5 is arranged above the leaching pipe 4. One side of the water mist nozzle 5 is connected to a water pipe 6. Considering the corrosive substances that may be produced by the sludge and microbial metabolism, the water mist nozzle 5 should be made of corrosion-resistant metal materials, such as stainless steel or specific alloy materials. A nutrient solution nozzle 7 is arranged below the leaching pipe 4, one side of the nutrient solution nozzle 7 is connected to a delivery pipe 8, and one side of the delivery pipe 8 is connected to a nutrient solution tank 9. The nutrient solution nozzle usually adopts a special internal structure, such as a combination of a straight pipe outlet pipe and a curved pipe outlet pipe. These designs help to adapt to the spraying environment in the leaching pipe 4. The nutrient solution nozzle 7 should be made of corrosion-resistant metal materials, such as stainless steel or specific alloy materials. The nutrient solution should use a new nutrient solution containing trace elements and nutrients such as carbon, nitrogen, and phosphorus. This nutrient solution is not only conducive to microbial growth and denitrification, but also can maintain the stability of the biochemical system;

[0024] A guide rod 10 is arranged at the inner center of the leaching tube 4, and a biofilm 11 is arranged around the outer wall of the guide rod 10, and a biorope 12 is arranged around the top of the biofilm 11. This method can not only increase the area of ​​microbial attachment, but also improve the distribution of microorganisms on the carrier surface, thereby optimizing the growth and performance of the biofilm during wastewater treatment. The biofilm of microorganisms on the carrier can be divided into two stages: microbial adsorption and fixed growth. By winding the biorope 12 on the surface of the biofilm 11 carrier, more recesses and attachment points can be provided to promote the initial adsorption and long-term fixation of microorganisms. The biorope 12 is usually made of high-strength polypropylene mixed weaving process and has a large tensile bearing capacity. This physical property enables the biorope to resist water flow impact and other physical pressures and maintain a stable biofilm 11 structure.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 3 As shown, see the following description for details:

[0027] As a preferred embodiment, the biofilm 11 and the bio-rope 12 fix the microorganisms on the surface by an embedding method, so that the microorganisms can grow and reproduce on their surface. Furthermore, the embedding method refers to embedding the microbial strains in a gel matrix suitable for their growth, and then integrating these gel particles into the interior or surface of the bio-rope. Commonly used gel materials include calcium alginate, carrageenan, etc. These materials can maintain the activity of the microorganisms while preventing them from falling off. This method can ensure that the immobilization process does not affect the activity and stability of the microorganisms.

[0028] As a preferred embodiment, the feeding mechanism 2 includes a protective frame 13, a feed port 14, a U-shaped tube 15 and a sludge pump 16. The feed port 14 is arranged on one side of the protective frame 13, and the U-shaped tube 15 is connected to one side of the feed port 14. The sludge pump 16 is arranged on one side of the U-shaped tube 15. Furthermore, the problems of sludge transportation and gas emission can be effectively solved, and the stability and processing efficiency of the whole system can be improved. Since the sludge pump 16 is connected to the bottom of the U-shaped tube 15, the flow rate and flow state of the sludge can be controlled by adjusting the power of the sludge pump 16. This design utilizes the gravity characteristics of the U-shaped tube 15, so that the sludge can be initially accelerated by gravity when entering the U-shaped tube 15, and then powered by the sludge pump 16 at the bottom to maintain its stable flow in the pipeline. This not only reduces the energy consumption of the sludge pump 16, but also improves the efficiency of sludge transmission.

[0029] As a preferred embodiment, an exhaust pipe 17 is provided on one side of the U-shaped tube 15, and the exhaust pipe 17 can discharge the air in the U-shaped tube 15. Furthermore, by arranging the exhaust pipe 17 on the U-shaped tube 15, the gas released from the sludge can be discharged in time to avoid the accumulation of gas in the U-shaped tube 15 to form a blockage. This design is particularly suitable for sludge with a high gas content, and can significantly reduce the risk of blockage of the U-shaped tube 15 due to gas accumulation.

[0030] As a preferred embodiment, several groups of water mist nozzles 5 are provided, and each group of water mist nozzles 5 is evenly arranged along the horizontal direction of the leaching pipe 4, so that the internal water mist of the leaching pipe 4 is evenly dispersed. Furthermore, the water mist nozzles 5 can be conveniently fixed on the leaching pipe 5 by threaded connection or snap-on installation, and the spray angle can be adjusted within a certain range.

[0031] As a preferred embodiment, several groups of nutrient solution nozzles 7 are provided, each group of nutrient solution nozzles 7 is evenly arranged in the horizontal direction along the bottom of the leaching tube 4, and each group of nutrient solution nozzles 7 is spaced apart from the water mist nozzles 5 arranged above the leaching tube 4. Furthermore, the nutrient solution nozzles 7 can evenly spray the nutrient solution over a larger area. Compared with traditional manual spraying or other mechanical power spraying methods, this way of setting the nutrient solution nozzles 7 can greatly improve work efficiency.

[0032] The working process of the utility model is as follows: first, the sludge is sent into the device through the U-shaped tube 15. The design of the U-shaped tube 15 utilizes the principles of gravity and fluid dynamics to enable the sludge to flow in the pipeline. During the sludge transportation process, the exhaust pipe 17 on the U-shaped tube 15 plays an important role. The sludge may contain gas, which needs to be discharged at an appropriate position to prevent the gas accumulation in the pipeline from forming a blockage or affecting the flow of sludge. Then the sludge enters the leaching tube 4 through the diversion tube 3, where the sludge is evenly distributed on the guide rod 10 of the microbial carrier wrapped with the biological rope 12. The design of the leaching tube 4 ensures that the sludge can be efficiently separated from the biological rope 12. The rope 12 contacts the sludge, providing sufficient nutrition and water for the growth and metabolism of microorganisms. In the leaching pipe 4, the water mist nozzle 5 and the nutrient solution nozzle 7 provide water and nutrition for the growth of microorganisms. The microorganisms attached to the biological rope begin to degrade and transform the organic matter in the sludge. This process not only reduces the organic load of the sludge, but also may produce some beneficial metabolites. The sludge treated by microorganisms can be further disposed or utilized, such as recycled as biofertilizer, or discharged into the natural environment after meeting the emission standards. The above is the working principle of the biological leaching equipment with real-time nutrient supply.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
