Description

Technical Field

[0001] The utility model particularly relates to a biofilm cleaning device suitable for an aeration head. Background Art

[0002] During sewage treatment plant operation, the aerobic tank requires compressed air to meet the microbial degradation needs of organic matter under aerobic conditions. This compressed air is usually distributed in the water using aeration heads. For highly biodegradable sewage, a layer of biofilm will gradually form on the aeration heads. As the biofilm thickens, it affects the aeration efficiency of the aeration heads. Over time, the aeration heads can become deformed and damaged, necessitating prompt cleaning to remove the biofilm attached to their surfaces. This is typically done by evacuating the aerobic tank to remove the sludge and water within, leaking out of the aeration heads. Manual scrubbing or high-pressure water flushing of the aeration heads is a time-consuming and labor-intensive process, impacting sewage treatment plant operation. Summary of the Invention

DETAILED DESCRIPTION

[0016] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0017] Reference below Figure 1 A description is given of a suitable aeration head biofilm cleaning device according to an embodiment of the utility model, including a main air duct 4, which is connected to an aeration group, and a plurality of aeration heads are respectively provided on the aeration groups. It also includes a drug dispensing box 5 and a dosing pump 8, which are connected to the drug dispensing box 5 and the dosing pump 8. The output port of the dosing pump 8 is provided with a drug delivery pipe 9, which is connected to the main air duct 4, and the drug delivery pipe 9 is connected to a dosing valve. The main air duct 4 is provided with an air valve, and the air valve is connected to the dosing valve. The aeration group is also connected to an exhaust pipe, and the exhaust pipe is connected to an exhaust valve.

[0018] This structure is applied to aerobic pool 1. This structure outputs the fungicide solution to the aeration group through the combination of the dispensing box and the dosing pump. The fungicide solution is used for online treatment to quickly and effectively eliminate the biofilm attached to the aeration head, improving maintenance efficiency and not affecting production.

[0019] This structure is provided with a drug dispensing box 5 and a dosing pump 8, which is used to add the fungicide solution to the aeration group; and an air valve and a dosing valve are added to control the amount of high-pressure gas entering the main air duct 4, and also control the amount of dosing of the dosing valve; the air valve, dosing valve and dosing pump 8 are respectively connected to the control panel, and the control panel implements the control of the working state, that is, to start or stop the work.

[0020] When cleaning is required, close the air valve of the main air duct 4 to be cleaned, open the dosing valve, start the dosing pump, and add the prepared concentration of fungicide solution (generally 200-500ppm) into the aeration group. The fungicide solution seeps through the micropores of the aeration head to kill the biofilm near the aeration head. Rinse and soak for 20 to 30 minutes to complete the killing of the biofilm, then close the dosing pump 8 and the dosing valve, open the air valve, open the drain valve, and drain the fungicide solution from the drain pipe to complete the biofilm removal.
