Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an aerated biological filter for wastewater treatment. Background Technology

[0002] Biologically aerated filters (BAFs) are a widely used bioreactor technology for wastewater treatment. They combine multiple mechanisms, including biodegradation, physical filtration, and chemical adsorption, to effectively remove pollutants such as organic matter, nitrogen, and phosphorus from wastewater. BAF technology offers advantages such as high treatment efficiency, small footprint, stable operation, and easy maintenance.

[0003] Existing aerated biological filters for wastewater treatment are not easy to adjust the position of the aeration heads during use, which can easily lead to wastewater in some dead areas not being effectively treated. Therefore, an aerated biological filter for wastewater treatment is proposed.

[0004] A wastewater treatment aerated biological filter disclosed in announcement number CN220845731U includes a filter tank, an inlet pipe, an outlet pipe, a sewage pipe, a filter screen, a biological filter membrane, a lifting mechanism, an aeration and cleaning mechanism, and a vibration mechanism. The filter screen and biological filter membrane are installed inside the filter tank, with the biological filter membrane located above the filter screen. The inlet pipe is located on the side wall of the filter tank below the filter screen, and the outlet pipe is located on the side wall of the filter tank above the biological filter membrane. The lifting mechanism is fixed to the outer wall of the filter tank and connected to the biological filter membrane and the filter screen. The aeration and cleaning mechanism is installed inside the filter tank below the filter screen. The aeration and cleaning mechanism includes an aeration plate, a support plate, a fixing box, an electric push rod I, a tilting plate, a scraper, a lead screw II, a motor II, an electric push rod II, a torsion spring, a rotating shaft, and a guide tube. This utility model can clean the bottom of the filter tank thoroughly and prevent the scraper from carrying back the unscraped sludge when it returns, thus preventing it from accumulating at the end of the filter tank away from the sewage pipe.

[0005] While the aforementioned patent achieves the goal of using an aeration plate to drive a scraper along screw II, with the scraper cleaning the sludge at the bottom of the filter tank to the discharge pipe, and then retracting the scraper to return to the end away from the discharge pipe to clean the bottom of the filter tank again, thus cleaning the bottom of the filter tank thoroughly and preventing the scraper from carrying back any unscraped sludge and accumulating it at the end of the filter tank away from the discharge pipe, this device does not easily agitate the wastewater, ensuring that oxygen is evenly distributed within the filter tank and avoiding localized oxygen deficiency.

[0006] Therefore, it is necessary to invent an aerated biological filter for wastewater treatment to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides an aerated biological filter for wastewater treatment, which has the following beneficial effects:

[0019] 1. This wastewater treatment aerated biological filter, through the setting of a drive mechanism and a magnetic attraction mechanism, when the power is turned on during aeration, the electromagnet is energized and generates magnetic force, causing the magnetic stirring rods at the bottom of the aeration tank to attract each other. Then, the drive motor at the top is started, which drives the main gear, rack and pinion and auxiliary gear at the bottom to rotate, which in turn causes the electromagnets on the surface of the main gear and auxiliary gear to rotate. The magnetic stirring rods are affected by the magnetic force and rotate at the bottom of the aeration tank, thereby achieving the effect of stirring the wastewater, ensuring that oxygen is evenly distributed in the aeration tank and avoiding local hypoxia.

[0020] 2. This wastewater treatment aerated biological filter, through the setting of a moving mechanism, when aeration is carried out, the blower is started, and the blower delivers external air to the inside of the aeration pipe through the hose and the flow pipe. Then, the rotating motor at the top is started, and the rotating motor drives the lead screw to rotate, so that the flow pipe connected to the threaded surface of the lead screw moves left and right along the surface of the lead screw. In turn, the aeration pipe at the bottom of the flow pipe moves left and right inside the aeration tank, which increases the aeration range and avoids the dead areas inside the aeration tank from not being effectively aerated, thus affecting the wastewater treatment effect.

[0034] In this invention, the working steps of the device are as follows:

[0035] First step: When aeration is performed, the power is turned on, the electromagnet 601 is energized and generates magnetic force, which causes the magnetic stirring rods 602 at the bottom of the aeration tank 1 to attract each other. Then, the drive motor 401 at the top is started.
