The wastewater generated during kitchen waste treatment is complex in composition, characterized by high ammonia nitrogen, high oil content, high suspended solids content, and a large amount of microorganisms and salts. If discharged directly without effective treatment, it will lead to eutrophication of water bodies, causing algal blooms, decreased dissolved oxygen, and disruption of the aquatic ecological balance; it will also pollute the soil, affect the surrounding ecological environment, and threaten residents' health. Therefore, a SBR reactor for kitchen waste wastewater treatment is needed.

The supernatant is then discharged through a drainage device. However, during operation, the high nitrogen and phosphorus content in the kitchen waste wastewater leads to insufficient anaerobic phosphorus release and inadequate carbon source for anoxic denitrification, resulting in low nitrogen and phosphorus removal efficiency and affecting the reactor's overall performance.

[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 4 This embodiment provides a technical solution: an SBR reactor for treating kitchen waste wastewater, including a main body 2 and a feeding mechanism 7. The feeding mechanism 7 is disposed inside the main body 2 and includes a fixed seat 701 fixedly connected to the upper part of one side wall inside the main body 2. The fixed seat 701 has a fixed groove 703 inside, and an installation block 705 is connected inside the fixed groove 703. The installation block 705 has external threads 704 uniformly arranged on its exterior. Specifically, the installation block 705 is threadedly connected to the fixed groove 703 through the external threads 704. A dispensing cylinder 702 is provided at the end of the installation block 705 away from the fixed seat 701. A composite microbial carrier is disposed inside the dispensing cylinder 702. The composite microbial carrier is made of cubic porous polyurethane material. Through holes 706 are uniformly opened on the dispensing cylinder 702.

[0031] The overall effect of Embodiment 1 is as follows: By inserting the mounting block 705 into the fixing groove 703 inside the fixing base 701, and then rotating the dispensing cylinder 702, the external thread 704 on the mounting block 705 engages with the internal thread inside the fixing groove 703, which facilitates the fixing of the dispensing cylinder 702. When the device is in operation, the composite microbial carrier inside the dispensing cylinder 702 begins to function. Under the impact of water flow, functional microorganisms such as nitrifying bacteria and polyphosphate-accumulating bacteria on the surface of the carrier are continuously released into the interior of the device body 2 through the micropores evenly distributed on the surface of the carrier, significantly enhancing the device's ability to degrade ammonia nitrogen and improving the device's treatment efficiency.

[0032] Example 2

[0033] The top of the main body 2 of the device is hinged to a box cover 1, and the top of the box cover 1 is equipped with a handle 6, which makes it convenient for the staff to open and close the box cover 1. An observation port 3 is provided on the upper side of one side of the main body 2. The observation port 3 is made of tempered glass, which makes it convenient for the staff to observe the inside of the main body 2. An accessory box 4 is provided at the end of the main body 2 near the observation port 3, which can provide load-bearing capacity.

[0034] An aeration pump 11 is installed at the bottom of the accessory box 4. Aeration ports 8 are evenly arranged at both ends inside the main body 2 of the device. The aeration ports 8 are connected to the output end of the aeration pump 11 through an air supply pipe. The aeration pump 11 works based on the principles of gas dynamics and fluid mechanics. The impeller is driven by a motor to rotate at high speed. The blades apply centrifugal force to the air, causing the air to accelerate radially and be thrown towards the pump casing. During this process, the air speed decreases and the pressure increases, and it is finally discharged through the air outlet. At the same time, a negative pressure is formed in the central area of ​​the impeller, creating a pressure difference with the external environment. Air in the atmosphere is continuously drawn into the pump under the action of the pressure difference, continuously replenishing the center of the impeller. This cycle achieves continuous air supply, meeting the dissolved oxygen requirements of different reaction stages and ensuring the stable and efficient operation of microbial metabolic activities. When selecting the aeration pump 11, the appropriate model should be selected according to the actual needs. All the components required in the aeration pump 11 are existing technologies and will not be described in detail below.

[0035] A drive motor 10 is installed in the middle part of the bottom of the main body 2 of the device. The drive motor 10 works on the principle that a current-carrying conductor moves under the force of a magnetic field. The stator generates a magnetic field, and the coils on the rotor become current-carrying conductors after being energized. They are subjected to Ampere force in the magnetic field, generating torque and causing the rotor to rotate. At the same time, the commutator continuously changes the direction of the coil current to ensure that the rotor rotates continuously in the same direction. When selecting the drive motor 10, an appropriate model should be selected according to actual needs. All the components required in the drive motor 10 are existing technologies and will not be described in detail below. A stirring rod 9 is installed at the output end of the drive motor 10.

[0036] The effect achieved by the entire embodiment 2 is as follows: kitchen waste wastewater is discharged into the interior of the main body 2 of the device, and then gas is sprayed out through the aeration port 8 by the operation of the aeration pump 11, which can aerate the wastewater inside the main body 2 of the device. After the aeration of the main body 2 of the device is completed, the aeration pump 11 is turned off by the control switch and the drive motor 10 is started, which can drive the stirring rod 9 to stir the wastewater inside the main body 2 of the device at a low speed. In a low dissolved oxygen environment, the denitrifying bacteria use the carbon source stored in the anaerobic stage to reduce nitrate nitrogen to nitrogen gas.

[0037] Example 3

[0038] A cylinder 5 is installed at the top of the main body 2 of the device. The cylinder 5 operates based on Pascal's principle and the laws of gas state changes. When compressed air enters the rodless chamber of the cylinder 5 through the solenoid valve, the gas pressure acts on the piston area to generate thrust, pushing the piston to move along the cylinder axis and causing the piston rod to extend, thus achieving linear reciprocating motion. When the compressed air switches to the rod chamber, the gas in the rodless chamber is discharged, and under the action of the pressure difference at both ends, the piston moves in the opposite direction, and the piston rod retracts. By controlling the on / off state and switching frequency of the solenoid valve, the start / stop, movement direction, and speed of the cylinder 5 can be precisely adjusted. When selecting a cylinder 5, the appropriate model should be selected according to actual needs. All the components required in the cylinder 5 mentioned above are existing technologies and will not be described in detail below.

[0039] The cylinder 5 has a suction port 14 at its output end. A partition plate 12 is located at the bottom of the accessory box 4, and a water pump 13 is mounted on top of the partition plate 12. The water pump 13 operates based on the energy conversion principle in fluid mechanics. A motor drives the impeller to rotate at high speed, and the blades apply centrifugal force or axial thrust to the liquid, giving it kinetic and pressure energy. In a centrifugal pump, the liquid is thrown from the center of the impeller to the edge, then enters the volute-shaped pump casing. The flow velocity decreases and is converted into pressure energy, which is then discharged after the pressure increases. In an axial flow pump, the liquid flows axially, and the impeller's propeller structure gives the liquid axial thrust, increasing the pressure. Before starting, the pump casing must be filled with liquid to create an initial vacuum. During operation, the negative pressure formed at the inlet continuously draws in liquid. By adjusting the motor frequency or changing the impeller diameter, precise adjustment of flow rate and head can be achieved to meet different operating conditions. When selecting a pump, the appropriate model should be chosen according to actual needs. All components required within the water pump 13 are existing technologies and will not be described further below.

[0040] The water pump 13 is equipped with a water supply pipe 15 at its input end. The end of the water supply pipe 15 away from the water pump 13 is connected to the water inlet 14. The accessory box 4 is provided with an air inlet 17 at the bottom of the end away from the main body 2. A drain pipe 16 is provided through the bottom of the accessory box 4 at the bottom of the end away from the main body 2, which can conveniently discharge the wastewater sucked into the accessory box 4.

[0041] The effect achieved by the entire embodiment 3 is as follows: by using the operation of cylinder 5, the suction port 14 can be moved to the upper clear liquid position, and by using the operation of water pump 13, the upper clear liquid can be sucked into the interior of accessory box 4 through water pipe 15.

[0042] Working principle: Kitchen wastewater is discharged into the main body 2 of the device. Then, the aeration pump 11 sprays gas through the aeration port 8 to aerate the wastewater inside the main body 2. After the aeration is completed, the aeration pump 11 is turned off by the control switch and the drive motor 10 is started. This drives the stirring rod 9 to stir the wastewater inside the main body 2 at low speed. In a low dissolved oxygen environment, denitrifying bacteria use the carbon source stored in the anaerobic stage to reduce nitrate nitrogen to nitrogen gas.

[0043] Secondly, by inserting the mounting block 705 into the fixing groove 703 inside the fixing seat 701, and then rotating the dispensing cylinder 702, the external thread 704 on the mounting block 705 engages with the internal thread inside the fixing groove 703, which facilitates the fixing of the dispensing cylinder 702. When the device is in operation, the composite microbial carrier inside the dispensing cylinder 702 begins to work. Under the impact of water flow, functional microorganisms such as nitrifying bacteria and polyphosphate-accumulating bacteria on the surface of the carrier are continuously released into the interior of the main body 2 of the device through the micropores evenly distributed on the surface of the carrier, significantly enhancing the device's ability to degrade ammonia nitrogen and improving the device's treatment efficiency.

[0044] Finally, after the device is completed, the wastewater inside the main body 2 is allowed to settle, and the activated sludge is separated into solid and liquid by gravity to form a clear sludge-water interface. Then, by using the operation of the cylinder 5, the suction port 14 can be moved to the upper clear liquid. By using the operation of the water pump 13, the upper clear liquid can be sucked into the interior of the accessory box 4 through the water pipe 15.
