[0003] A search revealed, for example, a utility model with publication number CN217352748U, which discloses a kitchen wastewater treatment device. The device includes a collection box on the side wall of the treatment tank, corresponding to the scraper. Two rotating shafts are located inside the treatment tank; a roll of filter paper is mounted on the right-hand shaft, and a motor is located on the side wall of the treatment tank, corresponding to the left-hand shaft. This utility model uses a sieve to remove organic solids from the wastewater. However, some solids, such as those in kitchen containers, still retain some wastewater. This wastewater is prone to leaking out during subsequent transport, affecting subsequent treatment processes. Furthermore, this utility model is not convenient for treating the residual wastewater inside the solids. Therefore, to address these shortcomings, the inventors propose a kitchen wastewater treatment device based on MBBR technology. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] This utility model discloses a kitchen wastewater treatment device based on MBBR technology, such as Figure 1-7 As shown, it includes a first shell 2 and a second shell 4. The first shell 2 is equipped with MBBR packing 205. MBBR packing 205 is a polyethylene suspended packing. When kitchen wastewater comes into contact with MBBR packing 205, the number of biofilms on MBBR packing 205 increases, thereby increasing the number of microorganisms on MBBR packing 205 and degrading organic pollutants in wastewater.

[0024] A rotating sleeve 2031 is rotatably connected to the outer top surface of the first housing 2. A filter cylinder 2033 is threadedly connected to the outer surface of the rotating sleeve 2031. The filter cylinder 2033 is made of stainless steel and has multiple filter holes on its outer surface. The filter cylinder 2033 is connected by threads so that the user can disassemble or install the filter cylinder 2033, thereby facilitating the disassembly and cleaning of the filter cylinder 2033.

[0025] A gear ring 2032 is fixedly installed at the top of the rotating sleeve 2031, and a protective cover 2034 is hinged to one side of the top surface of the gear ring 2032. An electric push rod 2035 is fixedly installed on the top surface of the protective cover 2034. The electric push rod 2035 is powered by an external power source, and the output end of the electric push rod 2035 passes through the protective cover 2034 and is fixedly installed with a pressing plate 2036. A first motor 2021 is fixedly installed on the outer top surface of the first housing 2, and a gear 2022 is fixedly installed on the output shaft of the first motor 2021. The gear 2022 meshes with the gear ring 2032.

[0026] Kitchen wastewater is poured into the filter cylinder 2033, which is threadedly connected to the rotating sleeve 2031. The protective cover 2034 is fixedly connected to the gear ring 2032 by bolts. The first electric push rod 2035 pushes out the extrusion plate 2036, which descends. The extrusion plate 2036 contacts the solids remaining in the filter cylinder 2033 to extrude them and squeeze out the wastewater remaining inside the solids. The first motor 2021 drives the gear 2022 to rotate, which in turn drives the gear ring 2032 and the filter cylinder 2033 to rotate. This accelerates the extrusion of wastewater, which falls to the bottom of the first housing 2 and comes into contact with the MBBR packing 205 inside the first housing 2. This increases the number of biofilms on the MBBR packing 205, thereby increasing the number of microorganisms on the MBBR packing 205, degrading organic pollutants in the wastewater, and facilitating the treatment of the wastewater remaining inside the solids.

[0027] A bracket 1 is fixedly installed on the outer bottom surface of the first housing 2. An air pump 201 is fixedly installed inside the bracket 1. The air pump 201 changes the volume of the sealed space through mechanical movement, thereby realizing the intake, compression and exhaust of gas.

[0028] An aeration pipe 202 is fixedly installed at the air outlet of the air pump 201. Multiple aeration heads 203 are fixedly installed on one side of the aeration pipe 202 extending into the interior of the first housing 2. The air pump 201 draws in ambient air and compresses it to generate high-pressure air. The compressed air output by the air pump 201 enters the aeration pipe 202 and then enters the multiple aeration heads 203. The compressed air reaches the inlet of the aeration head 203 through the aeration pipe 202. The air is dispersed into tiny bubbles through the micropores inside the aeration head 203. The tiny bubbles escape from the surface of the aeration head 203 and rise to the water surface to complete oxygen transfer. During the rise of the bubbles, the water flows, preventing sludge from settling and promoting biofilm renewal.

[0029] A lower clamping plate 206 is fixedly installed inside the first housing 2. An upper clamping plate 208 is provided on the top surface of the lower clamping plate 206. Both the lower clamping plate 206 and the upper clamping plate 208 are hollow designs. Both the upper clamping plate 208 and the lower clamping plate 206 are located below the filter cylinder 2033. Oil filter paper 207 is provided between the upper clamping plate 208 and the lower clamping plate 206. The upper clamping plate 208 and the lower clamping plate 206 clamp and fix the oil filter paper 207. The oil filter paper 207 achieves oil-water separation by adsorbing or blocking oil through its porous structure and physical interception.

[0030] A sealing door 3 is hinged to one side of the outer surface of the first housing 2.

[0031] Telescopic sleeves 2041 are fixedly installed on both sides of the interior of the first housing 2. Springs 2042 are fixedly installed on the inner top surface of the two telescopic sleeves 2041. Connecting rods 2043 are slidably connected inside the two telescopic sleeves 2041, and the two connecting rods 2043 are fixedly connected to the top surface of the upper clamping plate 208. The two springs 2042 are fixedly connected to the two connecting rods 2043 respectively. When the upper clamping plate 208 moves upward, it will push the two connecting rods 2043 to squeeze the two springs 2042.

[0032] The user pushes the upper clamp 208 upward, moving it away from the lower clamp 206, thus replacing the oil filter paper 207. When the upper clamp 208 is released, the compressed spring 2042 pushes the connecting rod 2043 and the upper clamp 208 downward, resetting them to their original positions. This clamps and fixes the replaced oil filter paper 207, making it easier to replace.

[0033] A connecting pipe 401 with a valve is fixedly connected between the first housing 2 and the second housing 4. An inlet pipe 402 is fixedly installed on one side of the outer top surface of the second housing 4. The user can pour disinfectant into the second housing 4 through the inlet pipe 402. A drain pipe 404 with a valve is fixedly installed on one side of the outer surface of the second housing 4. The treated kitchen wastewater can be discharged through the drain pipe 404.

[0034] A guide block 403 is fixedly installed on the inner bottom surface of the second housing 4, and the guide block 403 is inclined towards the drain pipe 404. A second motor 406 is fixedly installed inside the guide block 403. A stirring rod 405 is rotatably connected to the outer top surface of the guide block 403. The output shaft of the second motor 406 is fixedly connected to one end of the stirring rod 405 located inside the guide block 403. The second motor 406 is powered by an external power source. When the second motor 406 drives the stirring rod 405 to rotate, the disinfectant and kitchen wastewater inside the second housing 4 can be stirred and mixed.

[0035] The working principle of this utility model is as follows: The user first opens the sealing door 3, pours the MBBR filler 205 into the first housing 2, then pushes the upper clamping plate 208 up, so that the upper clamping plate 208 is away from the lower clamping plate 206, and places the filter paper 207 on the top surface of the lower clamping plate 206, so that the filter paper 207 is located between the upper clamping plate 208 and the lower clamping plate 206. When the upper clamping plate 208 is released, the compressed spring 2042 will push the connecting rod 2043 and the upper clamping plate 208 down to reset it, thus clamping and fixing the filter paper 207. The disinfectant is then poured into the second housing 4 through the liquid inlet pipe 402.

[0036] Kitchen wastewater can then be poured into the filter cylinder 2033, which is threadedly connected to the rotating sleeve 2031. The filter cylinder 2033 can intercept large solid objects in the kitchen wastewater. Then, the protective cover 2034 is fixedly connected to the toothed ring 2032 by bolts. The protective cover 2034 covers the opening on the top surface of the rotating sleeve 2031.

[0037] The first electric push rod 2035 pushes out the extrusion plate 2036, which descends. The extrusion plate 2036 comes into contact with the solids remaining in the filter cylinder 2033 to extrude them and squeeze out the wastewater remaining inside the solids. Then, the first motor 2021 drives the gear 2022 to rotate, which in turn drives the gear ring 2032 and the filter cylinder 2033 to rotate, accelerating the extruded wastewater to fall into the bottom of the first housing 2.

[0038] The squeezed-out wastewater and filtered wastewater will fall onto the oil filter paper 207 to filter the oil in the wastewater. After that, the wastewater will fall to the bottom of the first shell 2. The air pump 201 is started and the aeration head 203 accelerates the water flow, so that the wastewater can fully contact the MBBR packing 205, increase the number of biofilms on the MBBR packing 205, thereby increasing the number of microorganisms on the MBBR packing 205 and degrading the organic pollutants in the wastewater.

[0039] Wastewater from the first housing 2 enters the second housing 4 through the connecting pipe 401. When the second motor 406 drives the stirring rod 405 to rotate, the disinfectant and kitchen wastewater in the second housing 4 can be stirred and mixed to disinfect the wastewater. The treated wastewater will then be discharged through the drain pipe 404.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
