[0062] To better illustrate the technical effects of this utility model, the present utility model provides the following specific embodiments to explain the above technical process:

[0063] Example 1: A shrimp farm soil source and sewage source co-utilization system improves water quality stability, reduces water exchange frequency, is energy-saving and environmentally friendly, highly efficient, and has low operating costs. Specifically, it includes: a coaxial well 1, a sewage tank 3, a ground source heat pump unit 2, a sewage source heat pump unit 5, an anti-blocking machine 4, a water storage tank 7, a water pump, and valves.

[0064] Coaxial well 1 is a type of medium-deep geothermal well. Coaxial well 1 adds a casing in the middle of the original pumping well. The casing has holes at the bottom, forming a connection between the inside and outside of the casing, thus forming a closed pipeline. This technology does not consume groundwater and only extracts soil heat.

[0065] The outlet of coaxial well 1 is connected to the inlet on one side of ground source heat pump unit 2; the inlet of coaxial well 1 is connected to the outlet on one side of ground source heat pump unit 2.

[0066] Ground source heat pump unit 2 and wastewater source heat pump unit 5 are heat exchange devices. In ground source heat pump unit 2, the medium in the heat transfer medium channel is water. The water circulates in the channel between the coaxial well 1 and the evaporator of ground source heat pump unit 2, extracting heat from the coaxial well 1 and transferring it to the evaporator of the ground source heat pump unit. The medium in the refrigerant channel is water. The water circulates in the channel between the condenser of ground source heat pump unit 2 and the heat exchange pipes of the shrimp farming area 6, releasing heat from the condenser of ground source heat pump unit 2 to the heat exchange pipes of the shrimp farming area 6. The heat exchange between the evaporator and condenser in ground source heat pump unit 2 relies on the circulation of refrigerant in the internal pipes of the ground source heat pump unit, transferring heat from the evaporator to the condenser. Wastewater source heat pump unit 5 uses the same principle.

[0067] One inlet of the ground source heat pump unit 2 is connected to the outlet of the coaxial well 1, and the other outlet of the ground source heat pump unit 2 is connected to the inlet of the coaxial well 1. The other inlet of the ground source heat pump unit 2 is connected to the water source 19, and the other outlet of the ground source heat pump unit 2 is connected to the water storage tank 7. The water source 19 can be a tap water inlet.

[0068] The inlet of sewage pond 3 is connected to the water body of shrimp farming area 6, and the outlet of sewage pond 3 is connected to the anti-blocking machine 4.

[0069] The inlet of the anti-blocking machine 4 is connected to the sewage tank 3, and the outlet of the anti-blocking machine 4 is connected to one side inlet of the sewage source heat pump unit 5.

[0070] One side inlet of the wastewater source heat pump unit 5 is connected to the outlet of the anti-blocking machine 4, one side outlet of the wastewater source heat pump unit 5 is connected to the wastewater discharge outlet 20, and the other side of the wastewater source heat pump unit 5 is connected to the water heating system of the shrimp farming area 6.

[0071] The water inlet of shrimp farming area 6 is connected to the water storage tank 7, and the water outlet of shrimp farming area 6 is connected to the sewage tank 3.

[0072] This invention employs a soil-source and wastewater-source co-utilization system, which helps improve water quality stability, reduce water exchange frequency, ensure the healthy growth of shrimp, and is energy-saving, environmentally friendly, highly efficient, and has low operating costs.

[0073] When the water in the shrimp farming area is not changed, the ground source heat pump system is started to connect the ground source heat pump unit with the water heating system of the shrimp farming area, so as to fully absorb geothermal energy and maintain the water temperature of the shrimp farming area.

[0074] When the water in the shrimp farming area is changed, the water storage tank is connected to the water in the shrimp farming area to replace the water in the shrimp farming area.

[0075] When the water in the shrimp farming area has just been replaced, the wastewater source heat pump system is activated. This connects the wastewater source heat pump unit to the water heating system in the shrimp farming area, fully absorbing the waste heat from the wastewater and maintaining a constant water temperature. This system maximizes the utilization of resources and energy.

[0076] The water heating pipe in this invention is made of PE material, which is non-corrosive, does not form scale, and does not pollute the water, thereby improving water quality stability and reducing the frequency of water changes.

[0077] The method of using the shrimp farm soil and wastewater co-utilization system of this utility model is as follows:

[0078] When the water in shrimp farming area 6 is not changed (see...) Figure 2 Start the soil source heat pump system, turn on the ground source side circulating water pump 8 to connect the coaxial well 1 with the ground source heat pump unit 2, open the second valve 15 and the third valve 16, and turn on the terminal side circulating water pump 11 to connect the ground source heat pump unit 2 with the water heating system of the shrimp farming area 6, so as to fully absorb geothermal energy and maintain the water temperature of the shrimp farming area 6 unchanged.

[0079] When the water in shrimp farming area 6 is replaced, the sewage submersible pump 13 is turned on to connect the sewage tank 3 with the water in shrimp farming area 6, and the water in shrimp farming area 6 is discharged into the sewage tank 3. Then the sewage submersible pump 13 is turned off, and the water storage tank submersible pump 12 is turned on to connect the water storage tank 7 with the water in shrimp farming area 6, and the water in shrimp farming area 6 is replaced.

[0080] When the water in shrimp farming area 6 has just been replaced, the wastewater source heat pump system is started. Wastewater source pump 10 is turned on, connecting wastewater tank 3, anti-blocking machine 4, and wastewater source heat pump unit 5. The wastewater's residual heat is transferred to wastewater source heat pump unit 5, and the used wastewater is discharged through drain outlet 20. The fourth valve 17 and the fifth valve 18 are opened, and the terminal circulating water pump 11 is turned on, connecting wastewater source heat pump unit 5 to the water heating system of shrimp farming area 6. This fully absorbs the wastewater's residual heat, maintaining a constant water temperature in shrimp farming area 6.

[0081] When the water storage tank 7 needs to be replenished, the tap water submersible pump 9 is turned on, the first valve 14 is opened, and the second valve 15 and the third valve 16 are closed, so that the water from the water source 19 flows in, is heated by the ground source heat pump unit 2, and enters the water storage tank 7.

[0082] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
