Description

Technical Field

[0001] This utility model relates to the field of tailwater treatment technology, and more specifically, to fish farming tailwater treatment equipment. Background Technology

[0002] Fish farming wastewater refers to the unused aquaculture water discharged from the aquaculture system (including aquaculture ponds, factory aquaculture workshops, etc.) into the receiving water body during or after the aquaculture process. The wastewater contains a large amount of impurities, feces and other substances. Direct discharge of wastewater will pollute the receiving water quality, so it needs to be treated before it can be discharged.

[0003] Currently, the most common method for discharging wastewater is to dig several treatment ponds on the ground. Each pond has its own function, such as a flocculation pond, a sedimentation pond, and a disinfection pond. The wastewater is treated according to the treatment process until it meets the standards before it can be discharged into the receiving water body. However, digging several treatment ponds on the ground takes up a lot of land, and the multiple ponds also waste time and reduce the efficiency of wastewater treatment by transporting the wastewater during the treatment process. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a fish farming tailwater treatment device that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a fish farming wastewater treatment device, including a treatment chamber and an inlet pipe installed on the treatment chamber. The treatment chamber is also equipped with a wastewater biochemical treatment mechanism.

[0007] The wastewater biochemical treatment facility includes:

[0008] A coagulation chamber is located inside the treatment chamber, and a flocculation chamber is located adjacent to the coagulation chamber.

[0009] A sedimentation tank is located inside the treatment chamber, and a biochemical chamber is located around the sedimentation tank.

[0010] A connecting pipe is installed between two adjacent sections of the coagulation tank, flocculation tank, sedimentation tank, and biochemical tank, and is used for the transportation and treatment of effluent.

[0011] In a preferred embodiment, a sludge tank and an equipment room are provided at the bottom of the treatment chamber, with the sludge tank located below the coagulation and flocculation chambers.

[0012] In a preferred embodiment, one end of the inlet pipe extends into the interior of the coagulation chamber to deliver tailwater into the chamber.

[0013] In a preferred embodiment, the top of the coagulation chamber and the flocculation chamber are respectively provided with an agitator, the agitator including a drive motor and an agitator rod. The drive motor is fixedly installed on the top of the coagulation chamber and the flocculation chamber respectively, and the agitator rod is fixedly installed at the output end of the drive motor and is respectively located inside the coagulation chamber and the flocculation chamber.

[0014] In a preferred embodiment, an observation port is provided on the processing chamber.

[0015] In a preferred embodiment, a drain pipe is fixedly installed on the outer surface of the processing chamber, and one end of the drain pipe is connected to the interior of the biochemical chamber.

[0016] In a preferred embodiment, the outer surface of the processing chamber is provided with several slag discharge pipes, which are distributed on the same side.

[0017] In a preferred embodiment, the processing chamber is also provided with an inspection port.

[0018] The beneficial effects of the fish farm tailwater treatment equipment provided by this utility model include:

[0019] 1. By installing coagulation, flocculation, sedimentation, and biochemical treatment chambers on the treatment chamber, all chambers and pools can be integrated into one treatment chamber, greatly reducing the land area occupied. Furthermore, by shortening the distance between the chambers and pools, the effluent transportation time is reduced, improving the effluent treatment efficiency. The equipment adopts a concentric circle structure, with the outer circle for biochemical treatment and the inner circle for high-efficiency sedimentation. The equipment has a high degree of integration, a small footprint, and high treatment efficiency.

[0020] 2. By adding inclined tube sedimentation to the sedimentation tank and implementing partial sludge recirculation, the flocculation effect is increased while saving on chemicals. This combines multiple functions such as coagulation, flocculation, sedimentation, and sludge thickening, rapidly removing suspended solids (SS), turbidity, phosphorus, and some organic matter from the water. It significantly improves sedimentation efficiency, and the effluent turbidity meets high-standard water quality requirements. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example

[0028] Reference Figures 1-3 This utility model provides a technical solution: a fish farming wastewater treatment device, including a treatment chamber 1, and an inlet pipe 2 installed on the treatment chamber 1. The treatment chamber 1 is also equipped with a wastewater biochemical treatment mechanism 3. The wastewater biochemical treatment mechanism 3 includes a coagulation chamber 31, which is located inside the treatment chamber 1. A flocculation chamber 311 is located next to the coagulation chamber 31. A sedimentation tank 32 is located inside the treatment chamber 1. A biochemical chamber 321 is located around the sedimentation tank 32. A connecting pipe 33 is located between each pair of adjacent coagulation chamber 31, flocculation chamber 311, sedimentation tank 32 and biochemical chamber 321 for transporting and treating wastewater.

[0029] Reference Figures 1-3 In a preferred embodiment, a sludge tank 4 and an equipment room 5 are provided at the bottom of the treatment chamber 1. The sludge tank 4 is located below the coagulation chamber 31 and the flocculation chamber 311. The sludge tank 4 at the bottom of the treatment chamber allows the sludge generated inside the coagulation chamber 31 and the flocculation chamber 311 to enter the sludge tank 4 for subsequent unified treatment. It also facilitates the treatment of sludge in the effluent and makes it easier to transport the effluent to the sedimentation tank 32 for further treatment.

[0030] Equipment room 5 is set up to install some control equipment, such as pumps for sucking up tailwater and aeration blowers for aerating tailwater.

[0031] One end of the inlet pipe 2 extends into the interior of the coagulation chamber 31 to transport the wastewater into the coagulation chamber 31. The inlet pipe 2 extends out of the treatment chamber 1 and is equipped with a control valve. The inlet pipe 2 is made of stainless steel to prevent rusting during long-term use. The wastewater can be transported into the interior of the coagulation chamber 31 through the inlet pipe 2 for wastewater treatment.

[0032] Reference Figures 1-3 In a preferred embodiment, agitators are respectively provided on the top of the coagulation chamber 31 and the flocculation chamber 311. Top plates are fixedly installed on the top of the coagulation chamber 31 and the flocculation chamber 311. The agitators include a drive motor 6 and an agitator rod 7. The drive motor 6 is fixedly installed on the top plate for stable use. The drive motor 6 is fixedly installed on the top of the coagulation chamber 31 and the flocculation chamber 311. The drive motor 6 is selected with a power of 0.75kW-5.5kW, a speed of up to 150r / min, and a waterproof rating of IP55. The agitator rod 7 is fixedly installed at the output end of the drive motor 6 and is respectively set inside the coagulation chamber 31 and the flocculation chamber 311. The agitator rod 7 is vertically installed inside the coagulation chamber 31 and the flocculation chamber 311 and rotates for agitation treatment of the effluent. During the agitation process, coagulant is added to the coagulation chamber 31 and flocculant is added to the flocculation chamber 311 for effluent treatment.

[0033] By setting an observation port 8 on the treatment chamber 1, a transparent acrylic plate will be installed at the position of the observation port 8. During the treatment of the effluent, the staff can observe the treatment of the effluent through the observation port 8, which makes it easier to understand the progress of the treatment of the effluent.

[0034] This equipment will also have a drain pipe 9 fixedly installed on the outer surface of the treatment chamber 1. One end of the drain pipe 9 is connected to the inside of the biological chamber 321, and a control valve is installed on the outside of the drain pipe 9. The drain pipe 9 is located in the upper middle part of the outer surface of the biological chamber 321, which can discharge the effluent inside the biological chamber 321. The biological chamber 321 can be precisely aerated through the short-cut nitrification and denitrification process, and remove the concentration of organic matter such as ammonia nitrogen, COD, and total nitrogen in a low cost and high efficiency, thereby improving the treatment effect of the effluent. When the effluent treatment meets the standards, it can be discharged directly; otherwise, it will continue to be treated.

[0035] This equipment has several sludge discharge pipes 10 on the outer surface of the treatment chamber 1, which are distributed on the same side. The inside of the sludge discharge pipes 10 is connected to the inside of the sludge tank 4. When there is a large amount of sludge in the sludge tank 4, the sludge can be discharged from the inside of the sludge discharge pipes 10 to clean the sludge in time and avoid the sludge from accumulating inside the sludge tank 4, which would affect the subsequent effluent treatment.

[0036] The processing chamber 1 is also equipped with an inspection port 11.

[0037] Specifically, this equipment integrates the coagulation chamber 31, flocculation chamber 311, sedimentation tank 32 and biochemical chamber 321 inside the treatment chamber 1, which greatly reduces the floor space, reduces the tailwater transportation distance, improves the tailwater treatment efficiency, and is easy to use.

[0038] In use, connect the equipment to an external power source and pump the wastewater from outside into the inlet pipe 2. The wastewater is then transported into the coagulation chamber 31 through the inlet pipe 2 for preliminary treatment. By adding coagulant, the surface charge of the colloidal particles in the water is neutralized, causing them to destabilize and initially aggregate into tiny flocs (usually 1-100 μm in diameter), creating conditions for the subsequent flocculation stage. The wastewater is then transported into the flocculation chamber 311 through the connecting pipe 33 for the next step of treatment. After adding flocculant into the flocculation chamber 311, the tiny flocs formed in the coagulation stage are connected into larger (up to several millimeters) and denser flocs (lumps), facilitating subsequent separation by sedimentation or filtration.

[0039] Then, the effluent from the flocculation chamber 311 is transported to the sedimentation tank 32. The effluent undergoes sedimentation in the sedimentation tank 32, causing the particles in the effluent to settle to the bottom of the sedimentation tank 32. As the effluent in the sedimentation tank 32 increases, when the effluent moves to the position of the connecting pipe 33, it can enter the biochemical chamber 321. The biochemical chamber 321 quickly removes suspended solids (SS), turbidity, phosphorus, and some organic matter from the water.
