Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a microbial organic wastewater treatment device. Background Technology

[0002] Microorganisms can take up organic matter such as sugar, protein, fat, starch and other low molecular weight compounds from sewage and decompose these organic matter through their metabolic activities, thereby achieving the purpose of purifying sewage. According to the different oxygen requirements of microorganisms, wastewater biological treatment can be divided into two types: aerobic biological treatment and anaerobic biological treatment.

[0003] A microbial organic wastewater treatment device (CN210559961U) can be referenced in existing literature. The reference describes a device with an inlet pipe, the outer surface of which is equipped with a pH meter and a water valve switch. Both the pH meter and the water valve switch are connected to an external microcomputer. When the pH value is between 6.5 and 8, the water valve switch automatically opens. If the pH value is outside the range, the water valve switch automatically closes, thus controlling the pH value of the wastewater to prevent the growth and reproduction of microorganisms from being inhibited or killed, which would affect the treatment effect.

[0004] Among existing technologies, the activated sludge process is the most widely used aerobic biological treatment method. Its working principle is to oxygenate the wastewater by means of a blower or mechanical aeration device, which also acts as agitator and mixer, so that the activated sludge containing microorganisms can fully contact the organic pollutants in the wastewater. The concentration of pollutants is reduced by utilizing the oxidative decomposition ability of the microorganisms. As shown in the above literature, air is usually transported by an air pump or blower. However, in actual use, wastewater aeration is easily affected by water temperature, including dissolved oxygen saturation, oxygen transfer coefficient, microbial activity, and treatment efficiency, which will reduce the aeration treatment efficiency. Therefore, a microbial organic wastewater treatment device with temperature regulation function is designed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a microbial organic wastewater treatment device. This invention uses a temperature sensor to monitor the water temperature in real time. When the water temperature is outside the appropriate range, the wastewater can be heated or cooled via a heating box and a cooling hood, thus regulating the water temperature and reducing its impact on wastewater aeration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A microbial organic wastewater treatment device includes: a base and an aeration box. A blower is fixedly installed on the upper left side of the base. An exhaust branch pipe is connected to the right side of the blower's air outlet. The other end of the exhaust branch pipe is connected to a cooling hood. The aeration box is fixed above the cooling hood. A first heat dissipation fin and a second heat dissipation fin are fitted onto the outside of the aeration box. An exhaust main pipe is connected above the blower's air outlet. The exhaust main pipe is connected to an aeration pipe through a heating box. The other end of the aeration pipe is connected to an aeration disc. The aeration disc is located inside the aeration box. A temperature sensor is installed at the front end of the aeration box, and the probe of the temperature sensor is inserted into the aeration box.

[0008] The present invention is further configured such that the cooling shroud is fixed to the upper right side of the base, and multiple air holes are arranged in a ring at equal intervals above the cooling shroud.

[0009] The present invention is further configured such that a bracket is integrally welded to both the front and rear sides of the base, and an electric cylinder is fixedly installed on the surface of the bracket. The extension and retraction ends of the two electric cylinders are respectively connected to the first heat dissipation fin and the second heat dissipation fin.

[0010] The present invention is further configured such that a through-hole is provided in front of the first heat dissipation fin for the temperature sensor to pass through.

[0011] The present invention is further configured such that multiple electric heating tubes are installed inside the heating box, the air inlet of the heating box is located on the lower left side, and the air outlet of the heating box is located on the upper right side, wherein the exhaust pipe is connected to the air inlet and the aeration pipe is connected to the air outlet.

[0012] The present invention is further configured such that a central control panel is connected to the front left side of the base, and the temperature sensor is signal-connected to the central control panel.

[0013] The present invention is further configured such that a drain pipe is connected to the bottom right side of the aeration box, and a solenoid valve is installed on both the exhaust branch pipe and the drain pipe. Furthermore, a semi-circular No. 2 through-hole is provided on the right side of both the No. 1 heat dissipation fin and the No. 2 heat dissipation fin for connecting the drain pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This microbial organic wastewater treatment device monitors the water temperature inside the aeration tank in real time through a temperature sensor. When the water temperature is below a suitable range, the electric heating tube inside the heating tank can be turned on to heat the air supplied by the blower before it is introduced into the aeration tank, thereby heating the internal water temperature.

[0016] 2. Conversely, when the water temperature is higher than the appropriate range, the synchronous operation of the two electric cylinders drives the No. 1 and No. 2 heat dissipation fins to be fitted onto the outside of the aeration box. The No. 1 and No. 2 heat dissipation fins can improve the heat transfer efficiency. Then, the solenoid valve on the exhaust branch pipe is opened, so that the cooling fan blows air onto the No. 1 and No. 2 heat dissipation fins through the cooling fan shroud, which carries away the heat on the surface of the No. 1 and No. 2 heat dissipation fins, thereby reducing the water temperature.

[0017] Furthermore, by adjusting the temperature, the impact of water temperature on aeration can be reduced, thereby improving treatment efficiency. Attached Figure Description

[0027] Reference Figure 1-4 A microbial organic wastewater treatment device includes: a base 1, which serves as the support structure for the device; a blower 3 is fixedly installed on the upper left side of the base 1; a cooling hood 6 is installed on the upper right side of the base 1; an aeration box 8 is connected above the cooling hood 6; wastewater is injected into the opening at the top of the aeration box 8; and air is injected into the aeration box 8 by the blower 3 to aerate the wastewater inside.

[0028] Specifically, such as Figure 1-2 As shown, an exhaust branch pipe 4 is connected to the right side of the air outlet of the blower 3. The other end of the exhaust branch pipe 4 is connected to the cooling shroud 6. At the same time, multiple air holes 7 are arranged in a ring at equal intervals above the cooling shroud 6, and air is blown upward through the air holes 7.

[0029] Specifically, an exhaust pipe 12 is connected above the air outlet of the blower 3. The other end of the exhaust pipe 12 is connected to a heating box 13. The other end of the heating box 13 is connected to an aeration pipe 14. The aeration pipe 14 extends into the aeration box 8. An aeration disc 15 is provided at the other end of the aeration pipe 14. The aeration disc 15 is located inside the aeration box 8.

[0030] In this embodiment, during the aeration process, air is injected into the aeration box 8 through the exhaust pipe 12, aeration pipe 14, and aeration disc 15.

[0031] Specifically, such as Figure 1-2 As shown, a temperature sensor 11 is fixedly installed at the front end of the aeration box 8, and the probe of the temperature sensor 11 is inserted into the aeration box 8.

[0032] Furthermore, a central control panel 2 is connected to the front left side of the base 1. The temperature sensor 11 is connected to the central control panel 2, and the temperature data is displayed through the central control panel 2.

[0033] Specifically, such as Figure 4 As shown, multiple electric heating tubes 20 are installed inside the heating box 13. The air inlet of the heating box 13 is located on the lower left side, and the air outlet is located on the upper right side, so that the introduced air must pass through multiple electric heating tubes 20 completely, thereby improving the heating efficiency.

[0034] For details, please refer to Figure 1 and Figure 3 As shown, L-shaped brackets 16 are integrally connected to the front and rear sides of the base 1. Electric cylinders 17 are fixedly installed on the surface of the brackets 16. The extension and retraction ends of the two electric cylinders 17 are respectively fixed to the first heat dissipation fin 9 and the second heat dissipation fin 10.

[0035] Furthermore, both the first heat dissipation fin 9 and the second heat dissipation fin 10 are fitted onto the outside of the aeration box 8 and are tightly fitted to the aeration box 8.

[0036] Furthermore, the aeration box 8, the first heat dissipation fin 9, and the second heat dissipation fin 10 are all made of metal thermally conductive material. The first heat dissipation fin 9 and the second heat dissipation fin 10 increase the contact area with air through the fins on their surfaces, thereby improving the heat transfer efficiency.

[0037] It should be noted that water temperature also has a significant impact on the activity of microorganisms in wastewater. Most aerobic microorganisms are more active within a suitable temperature range (usually 15-30℃) and can decompose organic matter more effectively. When the water temperature is too high or too low, the activity of microorganisms will be inhibited, thereby affecting the degradation rate of organic matter.

[0038] In this embodiment, the temperature sensor 11 monitors the water temperature inside the aeration box 8 in real time and observes the value on the central control panel 2. When the water temperature is below a suitable range, the electric heating tube 20 inside the heating box 13 can be turned on. During the aeration process, the blower 3 sends air to the heating box 13 for heating treatment and then introduces it into the wastewater in the aeration box 8. The hot air and wastewater exchange heat and perform aeration treatment at the same time to increase the water temperature.

[0039] In another embodiment, when the water temperature is below a suitable range, the operation of the two electric cylinders 17 is activated, driving the first heat dissipation fin 9 and the second heat dissipation fin 10 to move towards the aeration box 8 and fit outside the aeration box 8. Then, the solenoid valve 5 on the exhaust branch pipe 4 is opened, so that some air is sent into the cooling shroud 6 through the exhaust branch pipe 4. The air is blown onto the first heat dissipation fin 9 and the second heat dissipation fin 10 through multiple air holes 7 on the top of the cooling shroud 6, which removes the heat from the surface of the first heat dissipation fin 9 and the second heat dissipation fin 10, thereby reducing the water temperature.

[0040] Furthermore, such as Figure 2As shown, a drain pipe 21 is connected to the right side of the aeration box 8. A solenoid valve 5 is also installed on the drain pipe 21. After aeration is completed, the solenoid valve 5 is opened to discharge the wastewater from the drain pipe 21.

[0041] And, as Figure 3 As shown, a square through-hole 18 is provided at the front end of the first heat dissipation fin 9 for the temperature sensor 11 to pass through; at the same time, a semi-circular through-hole 19 is provided on the right side of both the first heat dissipation fin 9 and the second heat dissipation fin 10. When the first heat dissipation fin 9 and the second heat dissipation fin 10 come into contact, a complete circular through-hole 19 is formed, which is fitted onto the outside of the drain pipe 21.

[0042] Working principle: When using this utility model, the temperature sensor 11 monitors the water temperature inside the aeration box 8 in real time. When the water temperature is below the appropriate range, the electric heating tube 20 inside the heating box 13 can be turned on to heat the air supplied by the blower 3 before it is introduced into the aeration box 8, thereby heating the internal water temperature. When the water temperature is above the appropriate range, the synchronous operation of the two electric cylinders 17 drives the first heat dissipation fin 9 and the second heat dissipation fin 10 to be sleeved on the outside of the aeration box 8. The first heat dissipation fin 9 and the second heat dissipation fin 10 can improve the heat transfer efficiency. Then, the solenoid valve 5 on the exhaust branch pipe 4 is opened, so that the cooling fan shroud 6 blows air onto the first heat dissipation fin 9 and the second heat dissipation fin 10, which carries away the heat on the surface of the first heat dissipation fin 9 and the second heat dissipation fin 10, thereby reducing the water temperature.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
