Description

Technical Field

[0001] This utility model relates to the field of aquaculture environmental engineering and water treatment technology, and in particular to an integrated tailwater treatment device for ponds and shorelines. Background Technology

[0002] With the intensive and large-scale development of aquaculture, stocking densities are constantly increasing, leading to a significant increase in feed intake and excrement. This results in pond wastewater containing high concentrations of pollutants such as suspended solids, organic matter, ammonia nitrogen, nitrite, and phosphorus. If this wastewater is discharged directly without effective treatment, it will severely pollute surrounding rivers, lakes, and other water bodies, causing a series of ecological and environmental problems such as eutrophication, algal blooms, and decreased dissolved oxygen, thus hindering the sustainable development of aquaculture.

[0003] Currently, the main methods for treating aquaculture wastewater include traditional sedimentation tanks, filter dams, and constructed wetlands. However, these methods are labor-intensive, have low treatment efficiency, and long hydraulic retention times, resulting in excessively long treatment cycles, which makes it difficult to meet the needs of rapid wastewater purification under high-density aquaculture models.

[0004] Therefore, it is necessary to design an integrated tailwater treatment system for ponds and shorelines to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of high labor intensity, low treatment efficiency, and long hydraulic retention time, this invention provides an integrated tailwater treatment device for ponds and shorelines.

The bank is located on the right side of the pond. A placement seat is placed on the top left side of the bank. A circulating water processor is fixedly connected to the top of the placement seat. The first delivery pipe is located in the middle left side of the circulating water processor.

The top of the spiral separation shaft passes through the sediment separator and is fixedly connected to the output shaft at the bottom of the motor.

[0007] Optionally, it also includes a feed hopper, with feed hoppers located at the left end and the upper left side of the feed hose.

[0008] Optionally, it also includes a foam separator, which is installed on the upper part of the outlet pipe.

[0009] Optionally, it also includes a first check valve and a second pump body, with the first check valve located on the right side of the first return pipe and the second pump body located in the middle of the first return pipe.

[0012] Optionally, it also includes a second reflux pipe, which is provided between the top of the solid-liquid separator and the upper part of the first reflux pipe.

A second one-way valve 20 is provided on the second conveying pipe 18. A motor 21 is fixedly connected to the top of sediment separator 19 by bolts. A spiral separation shaft 22 is rotatably connected to the inside of sediment separator 19. The top end of spiral separation shaft 22 passes through sediment separator 19 and is fixedly connected to the output shaft at the bottom of motor 21.

[0022] like Figure 3 and Figure 4 As shown, it also includes a feed hopper 9, and the feed hose 6 is provided with a feed hopper 9 at the left end and the upper left side.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a foam separator 12, which is installed on the upper part of the water outlet pipe 11.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a first check valve 13 and a second pump body 14. The first check valve 13 is provided on the right side of the first return pipe 10, and the second pump body 14 is provided in the middle of the first return pipe 10.

[0025] like Figure 2 As shown, it also includes a filter screen 15, a filter element 16, and a filter cotton 17. The filter screen 15 is provided on the lower side of the upper part of the circulating water processor 4, the filter element 16 is provided in the middle of the upper part of the circulating water processor 4, and the filter cotton 17 is provided on the upper side of the upper part of the circulating water processor 4.

[0026] like Figure 1 and Figure 3 As shown, it also includes a third conveying pipe 23, a solid-liquid separator 24, a third one-way valve 25, a collecting pipe 27, a third pump body 28, and a three-stage septic tank 29. The solid-liquid separator 24 is placed on the top right side of the bank 2. The third conveying pipe 23 is provided between the top of the solid-liquid separator 24 and the top of the sludge separator 19. The third one-way valve 25 is provided on the third conveying pipe 23. The collecting pipe 27 is connected between the solid-liquid separator 24 and the lower front side of the sludge separator 19. The third pump body 28 is provided at the front of the collecting pipe 27. The front end of the collecting pipe 27 is connected to the three-stage septic tank 29.

[0027] like Figure 1 and Figure 3 As shown, it also includes a second reflux pipe 26, which is provided between the top of the solid-liquid separator 24 and the upper part of the first reflux pipe 10.

[0028] When this device is needed to treat the aquaculture wastewater in pond 1, the first pump body 8 is started first. The first pump body 8 draws wastewater containing uneaten feed, feces and suspended solids from the lower part of pond 1 through the first delivery pipe 5 and the feed hose 6. The two feed hoppers 9 set at the left end and the upper part of the feed hose 6 expand the water suction range and can more effectively collect pollutants deposited at the bottom of pond 1. The pumped wastewater enters the circulating water processor 4 through the first delivery pipe 5. The fixing part 7 is used to fix the first delivery pipe 5. Then, the second pump body 14, motor 21 and solid-liquid separator 24 are started, which drives the water inside the circulating water processor 4 to pass through the filter screen 15, filter element 16 and filter cotton 17 from bottom to top for filtration. Then, it enters the first return pipe 10 and flows to the outlet pipe 11. The foam separator 12 on the outlet pipe 11 can remove organic foam and microbubbles in the water, further purifying the water quality. The water flow is then evenly sprayed back to pond 1 from multiple outlet holes at the bottom of the outlet pipe 11 to increase the oxygen content of the water flow and realize the recycling of the initially purified water.

[0029] Meanwhile, the sludge and heavier particles accumulated at the bottom of the circulating water processor 4 are discharged into the sediment separator 19 through the second conveying pipe 18. The second one-way valve 20 on the second conveying pipe 18 prevents the sediment from flowing back. Inside the sediment separator 19, the motor 21 drives the spiral separation shaft 22 to rotate at high speed, using centrifugal force to efficiently separate the water and solid particles in the sludge. The top of the sediment separator 19 transports the separated mud and water to the solid-liquid separator 24 through the third conveying pipe 23. The solid-liquid separator 24 performs secondary separation on the separated mud and water. The separated water is reinjected into the first return pipe 10 through the second return pipe 26 and flows back to the pond 1 through the action of the second pump body 14.

[0030] The first check valve 13 prevents the water separated by the solid-liquid separator 24 from flowing to the circulating water processor 4 through the first return pipe 10, and the third check valve 25 prevents the liquid in the solid-liquid separator 24 from flowing into the silt separator 19.

[0031] Finally, the third pump 28 is started, and the thick sludge separated by the screw shaft in the sludge separator 19 and the solid waste separated from the lower part of the solid-liquid separator 24 are collected together through the collection pipe 27 into the tertiary septic tank 29 for final anaerobic digestion and sedimentation treatment.
