[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for turtle and tortoise farming. Background Technology

[0002] In the field of turtle and tortoise farming, with the depletion of wild resources, artificial breeding, especially greenhouse farming, has become the main development trend. Greenhouse farming has the advantages of controllable greenhouse environment, stable temperature and water quality management, and improved breeding efficiency, which can bring significant economic benefits. However, if the wastewater generated during the turtle and tortoise farming process is not treated properly, it will pollute the environment. Therefore, wastewater treatment has become an important part of turtle and tortoise farming greenhouses, with the aim of reducing wastewater pollution to the environment and realizing the recycling of water resources.

[0003] Currently, common methods for treating aquaculture wastewater have many drawbacks. Among them, the treatment method that combines ecological ditches, artificial wetlands, and anaerobic biogas fermentation can treat wastewater, but it has obvious shortcomings. On the one hand, it requires a large amount of space, which undoubtedly increases aquaculture costs and land use pressure in the context of increasingly scarce land resources. On the other hand, the treatment time is long, making it difficult to quickly and effectively treat large amounts of wastewater, and it is difficult to ensure that the treated water quality meets discharge standards, thus failing to meet environmental protection requirements.

[0004] In addition, some farms use industrial wastewater treatment methods to treat aquaculture wastewater. This method involves complicated and cumbersome procedures, requiring professional personnel for operation and maintenance, which increases labor costs. At the same time, the daily operation and maintenance costs are high, including equipment maintenance and drug consumption, which is a considerable expense for aquaculture enterprises, limiting its widespread application in actual production.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figures 1 to 3 As shown, the present invention discloses a wastewater treatment device for turtle and tortoise farming, comprising a cavity 1, a filter chamber 2 disposed in the cavity 1, an anaerobic chamber 3 connected to the filter chamber 2, an aerobic chamber 4 connected to the anaerobic chamber 3, a disinfection chamber 5 connected to the aerobic chamber 4, and a reflux device 6 disposed between the filter chamber 2 and the disinfection chamber 5. The reflux device 6 includes a water pump 61, an output pipe 62 connected to the water pump 61, a three-way ball valve 63 connected to the output pipe 62, an input pipe 64 connected to one end of the three-way ball valve 63, and a discharge pipe 65 connected to the other end of the three-way ball valve 63. The output pipe 62 is connected to the disinfection chamber 5, and the input pipe 64 is connected to the filter chamber 2.

[0033] The three-way ball valve 63 is existing technology. It is a ball valve with three channels that can change the flow direction, distribution, or mixing of aquaculture wastewater. Its working principle is to control the flow state of the wastewater by rotating the ball, thereby controlling the on / off state between any two of the inlet pipe 64, outlet pipe 62, and discharge pipe 65. Using the three-way ball valve 63, the outlet pipe 62 is closed, while the discharge pipe 65 is connected to the inlet pipe 64. The aquaculture wastewater flows through the discharge pipe 65 to the inlet pipe 64, and then through the inlet pipe 64 into the filter chamber 2 for filtering solid waste and hydrolyzing esters in the wastewater into smaller molecules. The wastewater then flows from the filter chamber 2 to the anaerobic chamber 3, where large organic molecules are decomposed. Small molecule organic matter and insoluble organic matter are converted into soluble organic matter. The aquaculture wastewater then flows from anaerobic chamber 3 to aerobic chamber 4, where the organic matter is degraded. Finally, the wastewater flows from aerobic chamber 4 to disinfection chamber 5, where it is disinfected and sterilized. The disinfected wastewater then flows out along output pipe 62 driven by water pump 61. When the discharge pipe 65 is closed using three-way ball valve 63, the input pipe 64 and output pipe 62 are connected, allowing for a secondary circulation purification treatment of the wastewater until it meets discharge requirements. When the input pipe 64 is closed using three-way ball valve 63, the output pipe 62 and discharge pipe 65 are connected, allowing the wastewater meeting discharge requirements to be discharged along discharge pipe 65. This utility model has a compact and reasonable structure, saving space and reducing daily operation and maintenance costs. It adopts a centralized wastewater treatment and purification system, is simple and convenient to operate, and ensures that the water quality meets discharge standards.

[0034] In this embodiment, the filter chamber 2 is provided with a gravel layer 21, which is made of alkaline gravel. Specifically, the gravel layer 21 is made of alkaline gravel, the main components of which are usually calcium oxide (CaO) and magnesium oxide (MgO). These components give it a high alkalinity. Alkaline gravel includes alkaline rocks and alkaline volcanic rocks. Common minerals in alkaline rocks include potassium feldspar, sodium feldspar, nepheline, aegirine, and amphibole. Common types of alkaline volcanic rocks include brecciated alkaline coarse andesite and boulder-bearing alkaline coarse andesitic tuff. When aquaculture wastewater enters the filter chamber 2, the gravel layer 21 can filter out large solid wastes in the aquaculture wastewater. Due to its overall alkalinity, it helps to hydrolyze esters in the aquaculture wastewater into smaller molecules.

[0035] In this embodiment, the anaerobic chamber 3 is provided with a biological packing layer 31. Specifically, the biological packing layer 31 is rich in a large number of anaerobic microorganisms, including Clostridium, Bacteroides, Bifidobacterium, etc. The biological packing layer 31 will repeatedly come into contact with the aquaculture wastewater, hydrolyzing soluble organic matter such as starch, fiber, and carbohydrates in the aquaculture wastewater into organic acids, decomposing large organic molecules into small organic molecules, and converting insoluble organic matter into soluble organic matter.

[0036] In this embodiment, the aerobic chamber 4 is provided with a biological filter layer 41. Multiple biological filter layers 41 are provided, spaced apart and arranged in parallel. A motor 42 is provided on one side of the aerobic chamber 4. The output end of the motor 42 drives an impeller 43. The impeller 43 is arranged opposite to the biological filter layer 41. A blower 44 is provided in the cavity 1. The output end of the blower 44 is connected to a ventilation pipe 45. The ventilation pipe 45 is connected to an air storage chamber 46. An air nozzle 47 is provided in the air storage chamber 46. The air nozzle 47 passes through the aerobic chamber 4 and protrudes between two adjacent biological filter layers 41. Specifically, preferably, three biological filter layers 41 are provided, which are spaced apart and arranged in parallel. Multiple air nozzles 47 pass through the aerobic chamber 4 and protrude into the space between two adjacent biological filter layers 41. The blower 44 is started, and the blower 44 delivers compressed air to the air storage chamber 46 through the ventilation pipe 45. The air storage chamber 46 injects air into the aquaculture wastewater through the multiple air nozzles 47. At the same time, the motor 42 drives the impeller 43 to rotate. The rotating impeller 43 agitates the aquaculture wastewater to fully combine and dissolve the air with the aquaculture wastewater, greatly improving the oxygenation efficiency.

[0037] In this embodiment, a waterproof sealing ring 48 is provided at the bottom of the aerobic chamber 4, and the waterproof sealing ring 48 is sleeved on the outside of the air nozzle 47. Specifically, the waterproof sealing ring 48 is sleeved on the outside of the air nozzle 47, and has a good waterproof function to prevent the aquaculture wastewater from accidentally flowing out of the aerobic chamber 4.

[0038] In this embodiment, the top of the disinfection chamber 5 is provided with an ultraviolet (UV) component 51. The UV component 51 includes a housing 511, a UV germicidal lamp 512 disposed inside the housing 511, sealing plugs 513 disposed at both ends of the housing 511, a power connector 514 disposed in the UV germicidal lamp 512, a slot 515 disposed in the sealing plug 513, and a power cord 516 connected to the slot 515. A transparent cover 517 is provided on the outside of the housing 511. The UV germicidal lamp 512 is connected to the slot 515 through the power connector 514. An ultrasonic treatment box 52 is provided at the bottom of the disinfection chamber 5, and an ultrasonic generating tube 521 is disposed inside the ultrasonic treatment box 52. Specifically, the sealing plug 513 is fitted onto both ends of the outer casing 511, preventing moisture from penetrating the ultraviolet germicidal lamp 512, thus providing good waterproofing. The ultraviolet germicidal lamp 512 is placed inside the outer casing 511, and the ultraviolet rays emitted by the ultraviolet germicidal lamp 512 are projected into the disinfection chamber 5 through the transparent cover 517. The ultraviolet germicidal lamp 512 is connected to the slot 515 via the power connector 514, allowing the power connector 514 to be connected to an external power source, thereby turning on the ultraviolet germicidal lamp 512. An ultrasonic treatment box 52 is installed at the bottom of the disinfection chamber 5, where ultrasonic treatment... An ultrasonic generator tube 521 is fixedly connected inside the treatment box 52. Ultrasonic waves are emitted through the ultrasonic generator tube 521. The cavitation effect of ultrasonic waves has a strong ability to degrade organic matter in aquaculture wastewater. The degradation speed is fast and it can transform harmful organic matter into CO2, H2O, inorganic ions or organic matter that is less toxic and easier to degrade than the original organic matter. Furthermore, the synergistic effect of ultrasonic waves and ultraviolet rays can fundamentally remove toxic and harmful substances in aquaculture wastewater, thereby reducing the harm to human health and the environment and avoiding secondary pollution.

[0039] In this embodiment, the top of the disinfection chamber 5 is provided with a T-shaped connecting cylinder 518. The outer side of the outer shell 511 is provided with an external threaded section 519, and the inner side of the T-shaped connecting cylinder 518 is provided with an internal threaded section.

A waterproof ring 5110 is provided at one end of the T-shaped connecting cylinder 518 near the sealing plug 513. The waterproof ring 5110 is connected to the power cord 516. Specifically, the outer shell 511 is threadedly connected to the internal threaded section via the external threaded section 519, enabling installation and disassembly between the outer shell 511 and the T-shaped connecting cylinder 518. This facilitates easy installation and disassembly. The T-shaped connecting cylinder 518 is connected to the power cord 516 via the waterproof ring 5110, ensuring the normal operation of the power cord 516.
