After the motor 53 starts working, it drives the stirring rod 52 to rotate. The stirring rod 52 mixes the medicine and sewage. The first pH sensor 55 monitors in real time whether the pH value of the mixed solution meets the standard. The purpose of adding medicine is to make the pH value of the sewage tend to neutral.

[0052] When the pH value of the sewage does not meet the standard, it will preferentially flow back to the mixing area of the first water tank 18 through the first return water component; when the pH value meets the standard but aeration is insufficient, it will flow back to the second water tank 22 through the second return water component.

[0053] By opening the bottom manual valve 59 , the sewage in the first water tank 18 can be discharged.

[0054] When the solution mixed with the medicine in the first water tank 18 is guided into the second water tank 22, the first manual valve 61 can be opened to allow the solution to enter the second water tank 22 through the first manual valve 61 and the first three-way pipe 62; the second manual valve 65 can also be opened to allow the sewage on the other side of the partition inside the first water tank 18 (i.e., the sewage in the non-mixed area) to be guided into the second water tank 22 through the second manual valve 65 and the first three-way pipe 62.

[0055] The second pH sensor 83 in the second water tank 22 reads the pH value of the sewage. After the air compressor 17 starts working, it supplies air to the aeration plate 81. The aeration plate 81 aerates the sewage in the second water tank 22 to purify the sewage.

[0056] By opening the manual valve between the Y-type filter 31 and the second water tank 22, the aerated sewage passes through the Y-type filter 31, the Y-type filter 31 filters the sewage, and the filtered sewage enters the second three-way pipe 46, and the second three-way pipe 46 can divert the sewage.

[0057] When draining sewage to the outside, simply open the seventh manual valve 36 and the sixth manual valve 34 to allow the sewage to drain to the outside along the second three-way pipe 46, the sixth manual valve 34, the sixth three-way pipe 35 and the seventh manual valve 36.

After the magnetic pump 33 works, the sewage in the sixth three-way pipe 35 is pumped to the eighth manual valve 32, and then after passing through the seventh three-way pipe 38, it is divided into two channels. The first channel flows along the electric regulating valve 39, and the second channel flows along the fourth pressure transmitter. 42 and the ninth manual valve 41, and after mixing in the eighth three-way pipe 24, it flows into the third pressure transmitter 25, and then passes through the pipeline three-way pipe 92. On the one hand, it flows back to the first water tank 18 through the pipeline manual valve 91, and on the other hand, it flows back to the second water tank 22 through the pipeline manual valve 63. The electric regulating valve 39 is electrically controlled to control the on and off. After the ninth manual valve 41 is opened, the fourth pressure transmitter 42 is used to read the liquid pressure data in the pipeline. For the pipeline manual valve 63 and the pipeline manual valve 91, one or two of them can be selectively closed to make the sewage flow back only to the first water tank 18 or the second water tank 22, or to both the first water tank 18 and the second water tank 22.

[0059] When the sewage treated in the second water tank 22 is returned, there are two pipelines. The other pipeline is the second three-way pipe 46, the first pressure transmitter 45, the third manual valve 44, the third three-way pipe 43, the safety valve 74, the second pressure transmitter 73, the screw pump 75, the fourth three-way pipe 72, the electromagnetic flowmeter 71, the pneumatic gate valve 69, the manual butterfly valve 68, the fifth three-way pipe 66, the fourth manual valve 82 and the fifth manual valve 64. The pressure of the liquid on one side of the second three-way pipe 46 is monitored by the first pressure transmitter 45. After the third manual valve 44 is opened, the liquid flows through the third three-way pipe 43 in a bifurcated manner. One of the ways is through the safety valve 74, the second pressure transmitter 73 and the fourth three-way pipe 72. The safety valve 74 plays an overpressure emergency shutdown function. The safety valve 74 is in a normal pressure disconnection state. After the screw pump 75 works, it pumps the sewage in the third three-way pipe 43 into the fourth A circular connection is formed in the three-way pipe 72, which can enable the screw pump 75 to pressurize and pump the sewage on the one hand, and use the second pressure transmitter 73 to continue to monitor the sewage pressure in the fourth three-way pipe 72 on the other hand; the electromagnetic flowmeter 71 can display flow data, and the pneumatic gate valve 69 can realize the sewage interruption function under the control of the electric control box 21 under the air supply of the air pump 15, and the manual butterfly valve 68 can also realize the shut-off function through manual operation. After passing through the fifth three-way pipe 66, the sewage flows to the fourth manual valve 82 and the fifth manual valve 64. After the fifth manual valve 64 and the fourth manual valve 82 are opened respectively, the sewage can be returned to the internal area of the first water tank 18, and the sewage returned by the fifth manual valve 64 enters the internal area of the first water tank 18 below the ultrasonic sensor 54, and the sewage returned by the fourth manual valve 82 enters the internal area of the first water tank 18 below the ultrasonic level meter 51.

[0060] As for the safety valve 74 , the pressure of the safety valve 74 can be set to 0.3 MPa, and the safety valve 74 will automatically open to release pressure when the pipeline pressure exceeds the threshold.

[0061] The purpose of returning to the second water tank 22 is to allow the sewage to be aerated again, and the purpose of returning to the first water tank 18 is to mix and stir the sewage and the reagent again, and then pass through the second water tank 22 for aeration treatment, so as to treat the sewage multiple times and improve the sewage treatment effect.

[0062] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention; therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
