Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device using an ionized bed bioreactor. Background Technology

[0002] With the acceleration of industrialization and urbanization, global wastewater discharge has been increasing year by year. According to the "2023 China Water Resources Bulletin", my country's annual wastewater discharge has reached 73.5 billion tons. Wastewater generated by industries such as chemical, pharmaceutical and coking contains a large amount of recalcitrant organic matter (such as benzene series compounds and heterocyclic compounds), high salt or high nitrogen and phosphorus pollutants. In order to facilitate the treatment of wastewater, a flow-bed bioreactor wastewater treatment device is needed.

[0003] Regarding the aforementioned technologies, the applicant believes that when a fluidized bed bioreactor wastewater treatment device is in operation, wastewater is input into the device, and then air is delivered to the array of aeration heads using an air pump. The air is then sprayed out through the aeration heads to form an upward air-liquid flow. The water flow and air flow work together to keep the filled carrier particles in a suspended fluidized state. The biofilm on the surface of the carrier degrades pollutants such as organic matter, nitrogen, and phosphorus in the wastewater through adsorption and microbial metabolism. During the fluidization process, the collision of the carrier causes the aging biofilm to detach. The treated wastewater is discharged from the top, achieving efficient wastewater treatment. However, when the device is in operation, the airflow sprayed from the aeration heads is fixed, resulting in an uneven flow field inside the device. This creates a low-velocity dead zone inside the device, which leads to local hypoxia inside the device and affects the device's wastewater treatment effect. Utility Model Content

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1 to 4This embodiment provides a technical solution: a wastewater treatment device using an ionized bed bioreactor, comprising a main body 1 and an aeration mechanism 4. The aeration mechanism 4 is disposed inside the main body 1 and includes a rotating seat 406 rotatably disposed at the bottom of the main body 1. An aeration disc 402 is disposed at the top of the rotating seat 406, and the aeration disc 402 is hollow inside. Aeration heads 407 are evenly disposed at the top of the aeration disc 402. A driven gear 408 is disposed outside the rotating seat 406, and a driving gear 403 is meshed at one end of the driven gear 408. A drive motor 404 is disposed at the bottom of the main body 1. The drive motor 404 operates based on the principle of electromagnetic induction. When three-phase alternating current is applied to the stator winding, a rotating magnetic field is generated in the stator core. Its rotation speed is determined by the power supply frequency and the number of pole pairs of the motor. The rotor conductor cuts magnetic lines of force in the rotating magnetic field to generate an induced current. The current interacts with the magnetic field to generate electromagnetic torque, driving the rotor to rotate. When selecting the appropriate model, the appropriate model should be selected according to the actual needs. All the components required in the drive motor 404 are existing technologies and will not be described in detail below.

[0031] The output end of the drive motor 404 is connected to the drive gear 403, and the drive motor 404 drives the drive gear 403 to rotate.

[0032] The overall effect of Embodiment 1 is as follows: the drive motor 404 drives the active gear 403 to rotate via the transmission rod, which in turn drives the driven gear 408 to rotate the rotating seat 406, thereby causing the aeration disc 402 to rotate as well. During the rotation, the aeration disc 402 can spray microbubbles into different areas through the aeration head 407. This increases the gas content inside the main body 1 of the device, enhances the activity of the carrier layer 5, and minimizes the occurrence of local oxygen deficiency problems inside the main body 1 of the device.

[0033] Example 2

[0034] Both ends of the bottom of the device body 1 are provided with support bases 2, which form a welded integrated structure with the device body 1, which can easily support the device body 1. A carrier layer 5 is provided on the upper part of one end of the device body 1. The carrier layer 5 is filled with modified polyurethane. A water inlet pipe 6 is provided through the end of the device body 1 near the carrier layer 5, which facilitates the transportation of sewage into the device body 1. A base plate 7 is provided below the end of the device body 1 near the drive motor 404. A drain pipe 3 is provided through the end of the device body 1 near the base plate 7. A control valve is provided on the drain pipe 3. By opening the control valve, the treated sewage inside the device body 1 can be easily discharged. A partition plate 8 is provided in the middle part of the device body 1. An overflow port is opened at the top of the partition plate 8.

[0035] The effect achieved by the entire second embodiment is as follows: the synergistic effect of water flow and air flow makes the carrier particles filled inside the carrier layer 5 in a suspended fluidized state. The biofilm on the surface of the carrier layer 5 degrades pollutants such as organic matter, nitrogen, and phosphorus in the sewage through adsorption and microbial metabolism, which can facilitate the treatment of sewage. The treated sewage is discharged through the overflow port inside the partition plate 8, thus achieving efficient sewage treatment.

[0036] Example 3

[0037] The top of the main body 1 of the device is provided with an accessory box 401, which can conveniently protect the internal equipment. The accessory box 401 is equipped with an air pump 405. An inspection door is hinged to one side of the accessory box 401. An air supply pipe 409 is provided at the output end of the air pump 405. The end of the air supply pipe 409 away from the air pump 405 is connected to the aeration disc 402.

[0038] The gas pump 405 employs a volumetric gas delivery principle. A motor drives a rotor to perform periodic reciprocating motion within the pump body, changing the chamber volume to achieve gas intake and exhaust. When the chamber volume increases, the internal air pressure is lower than the external atmospheric pressure, automatically opening the inlet valve and allowing air to flow into the chamber through the inlet pipe. As the rotor rotates, the chamber volume decreases, compressing the gas and increasing the pressure. When the pressure exceeds a set value, the outlet valve opens, and the compressed air is delivered through the gas delivery pipe 409 to the aeration head 407, ultimately being ejected at a stable flow rate to form an upward gas-liquid flow, providing fluidization power for the carrier particles in the carrier layer 5. When selecting a pump, the appropriate model should be chosen based on actual needs. All components required within the drive motor 404 are existing technologies and will not be described further below.

[0039] The effect achieved by the entire embodiment 3 is as follows: air is delivered to the aeration head 407 by the air pump 405, and then sprayed out through the aeration head 407 to form an upward air-liquid flow. The water flow and air flow work together to make the carrier particles filled inside the carrier layer 5 in a suspended fluidized state.

[0040] Working principle: Wastewater is input into the main body 1 of the device through the inlet pipe 6. Air is delivered to the aeration head 407 by the air pump 405. The air is then sprayed out through the aeration head 407 to form an upward air-liquid flow. The water flow and air flow work together to make the carrier particles filled inside the carrier layer 5 in a suspended fluidized state. The biofilm on the surface of the carrier layer 5 adsorbs and degrades pollutants such as organic matter, nitrogen, and phosphorus in the wastewater through microbial metabolism, which can facilitate the treatment of wastewater. The treated wastewater is discharged through the overflow port inside the partition plate 8, realizing efficient wastewater treatment.

[0041] Secondly, the drive motor 404 is started using a control switch. The drive motor 404 drives the active gear 403 to rotate via a transmission rod, which in turn drives the driven gear 408 to rotate the rotating seat 406. This causes the aeration disc 402 to rotate accordingly. During rotation, the aeration disc 402 can spray microbubbles into different areas through the aeration head 407. This increases the gas content inside the main body 1 of the device, enhances the activity of the carrier layer 5, and minimizes the risk of localized oxygen deficiency within the main body 1 of the device.
