Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a temporary device for insufficient aeration in a biological treatment tank, comprising a blower 1, an inlet filter 6 fixedly installed on the right side of the blower 1, an vent silencer 5 installed on the inlet filter 6, the inlet filter 6 being used to filter impurities in the air entering the blower 1 to prevent damage to the blower 1, a connecting pipe 9 fixedly connected to the blower 1, an outlet check valve 3 fixedly installed on the connecting pipe 9, the outlet check valve 3 being used to prevent gas backflow and protect the stability of gas flow within the device, the connecting pipe 9... A temporary aeration pipe 7 leading to the biological treatment tank is provided on the right side. An installation component 2 is provided between the connecting pipe 9 and the temporary aeration pipe 7 leading to the biological treatment tank. An aeration component 8 is provided on the right side of the temporary aeration pipe 7 leading to the biological treatment tank. The installation component 2 includes a flange electric butterfly valve 21, which is fixedly installed on the connecting pipe 9. A rubber joint 4 is fixedly installed on the temporary aeration pipe 7 leading to the biological treatment tank. A flange electric butterfly valve 22 is installed on the rubber joint 4. The flange electric butterfly valve 21 and the flange electric butterfly valve 22 are connected by bolts and nuts.

[0022] The blower 1 is started, and air is drawn in through the inlet filter 6 fixedly installed on its right side. The function of the inlet filter 6 is to filter impurities in the air, preventing these impurities from entering the blower 1, thereby avoiding wear or damage to the impeller and other components of the blower 1, and ensuring that the blower 1 can operate stably and efficiently. The filtered air enters the cavity of the blower 1, and then, under the pressure of the blower 1, the air is transported along the fixed connecting pipe 9. A flange electric butterfly valve 21 and an outlet check valve 3 are sequentially installed on the connecting pipe 9. The flange electric butterfly valve 21 can flexibly adjust the gas flow rate according to the control signal to adapt to different aeration requirements, while the outlet check valve 3 can effectively prevent gas backflow, ensuring that the gas flows stably in the predetermined direction within the device, avoiding... To prevent equipment malfunctions or aeration abnormalities caused by gas backflow, air continues to be transmitted through rubber joint 4 to the temporary aeration pipe 7 leading to the biological treatment tank. Rubber joint 4 can buffer the stress caused by gas flow, equipment vibration, and other factors, while ensuring the sealing performance of the connection to prevent gas leakage. A flange electric butterfly valve 22 is installed on rubber joint 4, which works together with flange electric butterfly valve 21 to further precisely control the gas flow and on / off status leading to the temporary aeration pipe 7 of the biological treatment tank. Flanged electric butterfly valve 21 and flange electric butterfly valve 22 are connected by bolts and nuts to ensure the stability and reliability of the connection, so that the switching and flow regulation operations can be accurately executed during the automated control process.

[0023] Reference Figure 1 and Figure 2 The aeration assembly 8 includes an aeration pipe interface 81, a safety airbag 82, and an aeration disc 83. The aeration pipe interface 81 is connected to the temporary aeration pipe 7 leading to the biochemical tank. A safety airbag 82 is provided on the left side of the aeration pipe interface 81, and an aeration disc 83 is fixedly installed on the side of the aeration pipe interface 81 away from the safety airbag 82.

[0024] The air eventually reaches the aeration component 8, first entering the aeration pipe interface 81. The aeration pipe interface 81 serves as a transitional connection for the gas entering the aeration disc 83. The safety airbag 82 located on its left side plays a crucial role. When the entire aeration device operates underwater, the safety airbag 82 automatically adjusts its volume and internal pressure according to the water pressure, maintaining balance underwater and providing a stable working environment for the aeration disc 83, ensuring its normal operation. The aeration disc 83 then evenly disperses the incoming air into tiny bubbles. As these bubbles rise in the biological treatment tank, they come into full contact with the wastewater, effectively dissolving oxygen into the wastewater and promoting aerobic metabolism of microorganisms. This solves the problem of uneven aeration in the biological treatment system and the inability to reach the design sludge concentration standard. In this way, the entire temporary device effectively supplements the insufficient aeration in the biological treatment tank, improves the treatment effect, and ensures the normal operation of the biological treatment process.

[0025] Working Principle: When using this device, the blower 1 is first started, drawing in air through the inlet filter 6 fixedly installed on its right side. The inlet filter 6 filters out impurities and particles in the air, preventing damage to the blower 1. Next, the filtered air enters the blower 1 cavity and, under its pressure, is transmitted along the fixed connecting pipe 9. The flange electric butterfly valve 21 on the connecting pipe 9 can flexibly adjust the gas flow according to the control signal. The outlet check valve 3 prevents backflow of gas, ensuring stable gas flow. Subsequently, the air is transmitted through the rubber joint 4 to the temporary aeration pipe 7 leading to the biological treatment tank. The rubber joint 4 serves to connect, buffer stress, and ensure a seal. The flange electric butterfly valve 21 on it... 2. In conjunction with the flange electric butterfly valve 21, a secure connection is established via bolts and nuts, precisely controlling the gas flow and on / off state. Finally, the air reaches the aeration component 8, first entering the aeration pipe interface 81. The safety airbag 82 on its left side automatically adjusts its volume and internal pressure underwater according to the water pressure to maintain balance, creating a stable working environment for the aeration disc 83. The aeration disc 83 evenly disperses the air into tiny bubbles, which, as they rise in the biological treatment tank, come into full contact with the sewage, allowing oxygen to dissolve into the sewage and promoting aerobic metabolism of microorganisms. This solves the problems of uneven aeration in the biological treatment system and the inability of sludge concentration to meet design standards, effectively supplementing insufficient aeration in the biological treatment tank, improving treatment effect, and ensuring the normal operation of the biological treatment process.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
