Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an aeration device with monitoring function for wastewater treatment. Background Technology

[0002] Aeration devices play a crucial role in wastewater treatment. By injecting air or oxygen into the wastewater, they increase the dissolved oxygen content, providing the necessary conditions for microorganisms to survive and thus accelerating the biodegradation of organic pollutants in the wastewater. However, traditional monitoring of aeration tanks mainly relies on manual inspections, which is not only inefficient but also cannot provide real-time information on the aeration status.

[0003] Chinese Patent Publication No. CN217498816U discloses an aeration device for an aeration tank, belonging to the field of wastewater treatment technology. It includes an aeration tank, with a blower located at the upper part of one end. The blower is connected to a main pipe, and the outer wall of the main pipe is connected to multiple evenly distributed air supply pipes. The air supply pipes are fixedly installed on the bottom wall of the aeration tank, and multiple evenly distributed aeration components are located above the air supply pipes. It can be seen that the above technical solution lacks monitoring functionality, making the wastewater treatment process prone to problems and unable to be controlled in a timely manner.

[0034] This utility model provides an aeration device with monitoring function for sewage treatment, comprising:

[0035] Aeration tank 1, blower 2, aeration pipe 3, aerator 4, and monitoring unit;

[0036] The blower 2 is located outside the aeration tank 1;

[0037] The air inlet 5 of the aeration pipe 3 is connected to the blower 2. It extends vertically downward along the side wall of the aeration tank 1 to one end of the bottom of the aeration tank 1 and then extends horizontally to the other end of the bottom of the aeration tank 1. Several air outlets 6 are provided at equal intervals on the upper surface of the aeration pipe 3.

[0038] The aerator 4 is installed at the air outlet 6 of the aeration pipe 3, and the aerator 4 is connected to the aeration pipe 3 by a thread.

[0039] The monitoring unit includes an aeration volume monitoring unit 7 installed at the air inlet 5 of the aeration pipe 3 and a dissolved oxygen concentration monitoring unit 8 installed on the side wall of the aeration tank 1.

[0040] Specifically, area A shows the connection between the aerator 4 and the aeration pipe 3.

[0041] Specifically, the aeration pipe 3 is fixed by a fixing frame 9 set at the bottom of the aeration tank 1.

[0042] Specifically, a drive motor 10 is provided at the bottom of the blower 2 to drive the blower 2 to operate.

[0043] Specifically, a sealing ring 11 is provided at the connection between the aerator 4 and the aeration pipe 3. This arrangement can improve the tightness of the connection between the aerator 4 and the aeration pipe 3 and prevent air leakage during the aeration process.

[0044] Specifically, the aerator 4 is a disc aerator.

[0045] Specifically, a filter screen 12 is provided at the air inlet 5 of the aeration pipe 3. This arrangement can isolate impurities in the air outside the filter screen 12 and prevent impurities from entering the aerator 4 through the aeration pipe 3 and clogging the air outlet of the aerator 4.

[0046] Specifically, area B shows the connection between the aeration monitoring unit 7 and the filter 12 and the aeration pipe 3.

[0047] Specifically, the aeration monitoring unit 7 is a flow sensor.

[0048] Specifically, the dissolved oxygen concentration monitoring unit 8 is a dissolved oxygen concentration measuring instrument.

[0049] Specifically, a temperature sensor 13 is also provided. This configuration allows for the adjustment of the wastewater treatment scheme by monitoring the ambient temperature inside the aeration tank 1, thereby improving the efficiency of wastewater treatment.

[0050] Specifically, a control module is also provided, which is connected to the monitoring unit and the drive motor 10, and is used to adjust the aeration rate according to the dissolved oxygen concentration obtained by the dissolved oxygen concentration monitoring unit 8.

[0051] Specifically, the working process of the aeration device is as follows: the control module turns on the drive motor 10, causing the blower 2 to start working. The gas generated by the blower 2 enters the aeration pipe 3 through the air inlet 5, and then enters the aerator 4 through the air outlet 6. The aerator 4 injects the gas into the aeration tank 1 to start sewage treatment.

[0052] Specifically, when the aeration volume monitoring unit 7 detects that the gas flow rate is less than the preset gas flow rate, the gas flow rate can be restored to the preset gas flow rate by cleaning the filter screen 12; when the dissolved oxygen concentration monitoring unit 8 detects that the dissolved oxygen concentration in the aeration tank 1 is lower than the preset dissolved oxygen concentration, the control module can adjust the dissolved oxygen concentration to the preset dissolved oxygen concentration by adjusting the operating power of the drive motor 10.

[0053] Specifically, in this embodiment of the invention, cleaning the filter 12 can remove contaminants that clog the filter 12, thereby allowing the gas to flow normally.

[0054] Specifically, the process of cleaning the filter screen 12 includes: taking the filter screen 12 out of the aeration pipe 3 and rinsing it with clean water. If there is dirt that is difficult to rinse, use a brush to scrub it. After cleaning, dry the filter screen 12 in the sun.

[0055] Specifically, the control module has different power adjustment coefficients for the drive motor 10, wherein,

[0056] If the dissolved oxygen concentration difference is less than the preset dissolved oxygen concentration difference of 0.3 mg / L, the power of the drive motor 10 is adjusted to the corresponding value using the first power adjustment coefficient of 1.02.

[0057] If the dissolved oxygen concentration difference is greater than or equal to the preset dissolved oxygen concentration difference, the power of the drive motor 10 is adjusted to the corresponding value using the second power adjustment coefficient of 1.05.

[0058] The dissolved oxygen concentration difference is the difference between the preset dissolved oxygen concentration and the actual dissolved oxygen concentration.

[0059] In this embodiment of the present invention, the preset dissolved oxygen concentration difference is 0.3 mg / L, but the above value is not limited to this, and those skilled in the art can adjust the value according to actual needs.

[0060] Specifically, the preset gas flow rate is, for example, 1 m³ / h. 3 / h, the preset dissolved oxygen concentration is, for example, 2mg / L, but is not limited to any specific value and can be set according to the actual wastewater treatment situation.

[0061] For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
