A circulation mechanism 5 for facilitating the flow of liquid in the biological treatment cylinder 3 is arranged on one side of the biological treatment cylinder 3. The circulation mechanism 5 includes a mounting cylinder 51. A liquid inlet pipe 52 is connected to one side of the mounting cylinder 51. The end of the liquid inlet pipe 52 away from the mounting cylinder 51 passes through the biological treatment cylinder 3 and extends to the interior of the biological treatment cylinder 3. The other side of the mounting cylinder 51 is connected to a liquid outlet pipe 53. The end of the liquid outlet pipe 53 away from the mounting cylinder 51 is connected to the biological treatment cylinder 3. The mounting cylinder 51 is provided with a feeding mechanism 55 for feeding, and the liquid inlet pipe 52 is provided with a circulation mechanism for driving the flow of circulating liquid. The water pump 54, the circulating water pump 54 is connected to the control system and the power supply through a wire, the liquid inlet pipe 52 is connected to the inlet and outlet of the circulating water pump 54, the feeding mechanism 55 includes a support frame 551, a feeding pipe 552 is arranged on the top of the support frame 551, the feeding pipe 552 penetrates the support frame 551 and is fixedly connected to the support frame 551, the bottom end of the feeding pipe 552 is rotatably connected to the feeding pipe 554 through a connecting head 553, the feeding pipe 554 is provided with an adjusting component 555 for adjusting the feeding rate, the top end of the connecting head 553 is fixedly connected to the top of the inner wall of the support frame 551, the bottom end of the feeding pipe 554 penetrates the mounting cylinder 51 and is rotatably connected to the mounting cylinder 51, and the surface of the feeding pipe 554 is fixedly connected to a driving impeller 556.

[0023] Through the coordinated arrangement of the circulation mechanism 5 and the feeding mechanism 55, the regulating liquid is added to the circulating liquid. After the regulating liquid and the circulating liquid are fully mixed, they enter the biological treatment cylinder 3, which greatly reduces the impact of the regulating liquid directly entering the microorganisms in the biological treatment cylinder 3, ensuring the activity of the biofilm while reducing the impact on the waste gas treatment efficiency.

[0024] Figure 3 and 4A second embodiment is shown, and its main difference from the first embodiment is that an adjusting component 555 includes an adjusting cylinder 5551, a feeding pipe 554 is connected to the adjusting cylinder 5551, a partition plate 5552 is fixedly connected to the inner wall of the adjusting cylinder 5551, a connecting rod 5553 is fixedly connected to one side of the partition plate 5552, a counterweight block 5554 is fixedly connected to one end of the connecting rod 5553, the connecting rod 5553 passes through the partition plate 5552 and extends to the other side of the partition plate 5552, an end of the connecting rod 5553 away from the counterweight block 5554 is fixedly connected to an adjusting block 5555, a return spring 5556 is fixedly connected to one side of the partition plate 5552 and on the surface of the connecting rod 5553, and an end of the return spring 5556 away from the partition plate 5552 is fixedly connected to the adjusting block 5555.

[0025] Through the setting of the adjustment component 555, the greater the flow rate of the circulating liquid, the greater the centrifugal force exerted on the counterweight block 5554, the larger the opening of the adjustment block 5555, and the greater the rate of adding the adjusting liquid. That is, the rate of adding the adjusting liquid can be automatically adjusted according to the flow rate of the circulating liquid, thereby further reducing the influence of the adjusting liquid on the microorganisms in the biological treatment cylinder.

[0026] When the equipment is used to treat waste gas, the waste gas in the gas storage cylinder 1 enters the biological treatment cylinder 3 through the connecting pipe 2, and the waste gas is degraded by the microorganisms in the biological treatment cylinder 3 and enters the purification cylinder 4 for photolysis treatment. The treated gas is discharged from the purification cylinder 4. When the pH value in the biological treatment cylinder 3 needs to be adjusted, the circulating water pump 54 is turned on through the control panel. The circulating water pump 54 works to suck out the liquid in the biological treatment cylinder 3 through the liquid inlet pipe 52 and then re-send it into the biological treatment cylinder 3 through the installation cylinder 51 and the liquid outlet pipe 53. The liquid passes through the inlet pipe 52. When the liquid pipe 52 enters the installation barrel 51, it pushes the driving impeller 556 to drive the feed pipe 554 to rotate together. The rotation of the feed pipe 554 drives the adjusting barrel 5551 and the counterweight block 5554 to rotate together. The counterweight block 5554 rotates and drives the adjusting block 5555 to open through the connecting rod 5553 under the action of centrifugal force. The regulating liquid can enter the installation barrel 51 through the feeding pipe 552 and the feed pipe 554 and mix with the liquid in the installation barrel 51, and then enter the biological treatment barrel 3 through the liquid outlet pipe 53 to adjust the pH value in the biological treatment barrel 3.
