Description

Technical Field

[0001] This utility model relates to the technical field of greywater treatment devices, specifically to a multi-stage greywater treatment device. Background Technology

[0002] Greywater treatment is a process of treating wastewater to meet non-potable water standards and then directly reusing it for daily life, achieving direct recycling of water resources. The main purpose of greywater treatment is to treat relatively good domestic wastewater using simple technologies for non-potable use, such as car washing, watering green spaces, flushing toilets, and cooling, thereby fully utilizing water resources and reducing the pollution caused by direct wastewater discharge. This treatment method includes physical, chemical, and biological technologies, such as membrane filtration, biological adsorption, and oxidative decomposition, to ensure that the treated water meets certain standards and can be reused within a specific range.

[0003] Existing greywater treatment devices typically use multi-stage filtration to filter wastewater step by step before use. Before treatment, the wastewater is usually settled. However, existing greywater treatment devices usually add wastewater directly into the sedimentation tank during sedimentation. Since the wastewater contains a lot of impurities, the amount of impurities in the sedimentation tank increases after the support is discharged into the sedimentation tank, requiring regular cleaning, which increases the cleaning frequency and reduces the efficiency of greywater treatment. To address this, we propose a multi-stage greywater treatment device to facilitate impurity filtration before sedimentation in greywater treatment, reducing the frequency of manual cleaning of the sedimentation tank. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a multi-stage greywater treatment device.

[0005] The technical solution adopted by this utility model to solve its technical problem is a multi-stage greywater treatment device, including a bottom plate and a sedimentation tank. A pre-treatment mechanism is installed on the top of the sedimentation tank. The pre-treatment mechanism is composed of a box frame, a honeycomb plate, a vertical plate, an electric telescopic rod, a scraper, a waste discharge trough, a sealing plate, a rubber pad, and a locking buckle. The box frame is installed on the top of the sedimentation tank. A honeycomb plate for filtering is welded to the inner wall of the box frame. A waste discharge trough is opened in the frame wall of the box frame. The sealing plate that seals the waste discharge trough is connected to the box wall of the box frame by a hinge. A rubber pad is adhered to the wall of the sealing plate. A locking buckle that connects to the box frame is installed on the wall of the sealing plate. A vertical plate is installed on the frame wall of the box frame by bolts. An electric telescopic rod is installed on the wall of the vertical plate by bolts. A scraper is installed at the output end of the electric telescopic rod, and the scraper is attached to the honeycomb plate.

[0006] By adopting the above technical solution, when adding sewage into the sedimentation tank for impurity removal, a pre-treatment mechanism is installed at the top of the sedimentation tank. This pre-treatment mechanism consists of a frame, honeycomb panels, vertical plates, an electric telescopic rod, a scraper, a waste discharge trough, a sealing plate, rubber pads, and a locking mechanism. After personnel add sewage into the frame, the honeycomb panels welded inside the frame block impurities in the sewage, allowing the sewage to enter the sedimentation tank through the honeycomb panels. The impurities are located at the top of the honeycomb panels. When too many impurities accumulate, personnel open the locking mechanism, rotate the sealing plate, and control the electric telescopic rod via the controller. This causes the electric telescopic rod to push the scraper, which moves at the honeycomb panels, allowing the impurities to be discharged through the waste discharge trough. This prevents excessive impurities from entering the sedimentation tank, avoiding excessive garbage in the sedimentation tank, increasing the frequency of cleaning the sedimentation tank, and affecting the efficiency of wastewater treatment.

[0007] Specifically, it also includes a disinfection mechanism, which is installed on the top of the base plate.

[0008] By adopting the above technical solutions, wastewater can be disinfected through disinfection facilities.

[0009] Specifically, the disinfection mechanism is composed of a disinfection pool, a motor, a rotating shaft, and blades. The disinfection pool is installed at the top of the base plate, and the motor is bolted to the outer wall of the disinfection pool. The output end of the motor is equipped with a rotating shaft, which is located inside the disinfection pool. Blades are welded to the shaft wall of the rotating shaft.

[0010] By adopting the above technical solution, when disinfecting the water after the membrane bioreactor, the water is pumped and transported to the disinfection tank by the pump body. A disinfection mechanism is installed on the top of the bottom plate. The disinfection mechanism is composed of a disinfection tank, a motor, a rotating shaft, and blades. When the sewage is transported to the disinfection tank, the personnel add disinfectant to the disinfection tank. The controller controls the motor, which drives the rotating shaft at its output end to rotate. The rotating shaft drives the blades to rotate, so as to stir and mix the disinfectant in the disinfection tank evenly and improve the disinfection efficiency of the sewage.

[0011] Specifically, a sedimentation tank, an anoxic tank, and a membrane bioreactor are installed at the top of the bottom plate.

[0012] By adopting the above technical solution, the sewage is first settled in a sedimentation tank, and then the biological organisms in the sewage are oxidized in an anoxic tank. The principle of the membrane bioreactor is as follows: In the MBR system, microorganisms attach to the surface of the carrier to form a biofilm. These microorganisms use organic substrates to grow and reproduce, and gradually form a biochemically active biofilm on the surface of the carrier. The biofilm has a strong adsorption capacity and can further adsorb and decompose pollutants in the sewage in the form of suspension, colloidal and dissolved substances. The microorganisms in the biofilm convert organic and inorganic substances into harmless substances, such as carbon dioxide and water, through metabolism.

[0013] Specifically, the disinfection tank, membrane bioreactor, anoxic tank, and sedimentation tank are all connected by a pump.

[0014] By adopting the above technical solution, sewage can be conveniently transported in stages through the pump body.

[0015] Specifically, a blower is installed at the top of the base plate, an exhaust pipe is installed at the output end of the blower, and two diversion pipes are welded to the wall of the exhaust pipe, and the diversion pipes are correspondingly inserted into the anoxic tank and the membrane bioreactor.

[0016] By adopting the above technical solution, air is blown by a blower, and the air enters the diversion pipe through the exhaust pipe. The air is then blown into the anaerobic tank and the membrane bioreactor through the diversion pipe, so that the wastewater in the anaerobic tank and the membrane bioreactor is oxidized and impurities are removed.

[0017] Specifically, a controller for controlling the electric telescopic rod, blower, motor and pump is installed on the outer wall of the sedimentation tank.

[0018] By adopting the above technical solution, the electric telescopic pole, blower, motor and pump can be easily controlled through the controller.

[0019] The beneficial effects of this utility model are:

[0020] (1) The multi-stage greywater treatment device of this utility model removes impurities from sewage when it is added to the sedimentation tank. The top of the sedimentation tank is equipped with a pre-positioning mechanism, which is composed of a box frame, honeycomb plate, vertical plate, electric telescopic rod, scraper, discharge trough, sealing plate, rubber pad and buckle. After the sewage is added to the box frame, the honeycomb plate welded inside the box frame blocks the impurities in the sewage, allowing the sewage to enter the sedimentation tank through the honeycomb plate. The impurities are located at the top of the honeycomb plate. When too many impurities accumulate, the personnel open the buckle, rotate the sealing plate, and control the electric telescopic rod through the controller, so that the electric telescopic rod pushes the scraper, and the scraper moves at the honeycomb plate, allowing the impurities to be discharged through the discharge trough. This avoids too many impurities entering the sedimentation tank, causing too much garbage in the sedimentation tank, increasing the number of times the personnel clean the sedimentation tank, and affecting the efficiency of greywater treatment.

[0021] (2) The multi-stage greywater treatment device of this utility model disinfects the water after the membrane bioreactor. After the water is pumped and transported to the disinfection tank by the pump body, a disinfection mechanism is installed at the top of the bottom plate. The disinfection mechanism is composed of a disinfection tank, a motor, a rotating shaft and blades. After the sewage is transported to the disinfection tank, the personnel add disinfectant to the disinfection tank and control the motor through the controller, so that the motor drives the rotating shaft at its output end to rotate, thereby driving the blades to rotate, so as to stir and mix the disinfectant in the disinfection tank evenly and improve the disinfection efficiency of sewage.

[0027] 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.

[0028] As one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the multi-stage greywater treatment device of this utility model includes a base plate 1 and a sedimentation tank 3. A pre-processing mechanism 2 is installed on the top of the sedimentation tank 3. The pre-processing mechanism 2 is composed of a frame 201, a honeycomb plate 202, a vertical plate 203, an electric telescopic rod 204, a scraper 205, a waste discharge trough 206, a sealing plate 207, a rubber pad 208, and a latch 209. The frame 201 is installed on the top of the sedimentation tank 3. A filter honeycomb plate 202 is welded to the inner wall of the frame 201. An opening is formed in the frame wall of the frame 201. The box frame 201 has a discharge trough 206. The box wall of the box frame 201 is connected to a sealing plate 207 that seals the discharge trough 206 via a hinge. A rubber pad 208 is adhered to the wall of the sealing plate 207. A latch 209 for connecting the box frame 201 is installed on the wall of the box frame 201 via bolts. An electric telescopic rod 204 is installed on the wall of the vertical plate 203 via bolts. A scraper 205 is installed at the output end of the electric telescopic rod 204, and the scraper 205 is attached to the honeycomb plate 202.

[0029] In use, when wastewater is added to sedimentation tank 3 for impurity removal, a pre-treatment mechanism 2 is installed on the top of sedimentation tank 3. This pre-treatment mechanism 2 is composed of a frame 201, a honeycomb panel 202, a vertical plate 203, an electric telescopic rod 204, a scraper 205, a waste discharge trough 206, a sealing plate 207, a rubber pad 208, and a latch 209. After personnel add wastewater to the frame 201, the honeycomb panel 202 welded inside the frame 201 blocks impurities in the wastewater, allowing the wastewater to pass through the honeycomb... When plate 202 enters the sedimentation tank 3, impurities are located on top of honeycomb plate 202. When too many impurities accumulate, personnel open the latch 209, rotate the sealing plate 207, and control the electric telescopic rod 204 through the controller 4. The electric telescopic rod 204 pushes the scraper 205, which moves at the honeycomb plate 202, allowing the impurities to be discharged through the impurity discharge trough. This prevents too many impurities from entering the sedimentation tank 3, which would cause excessive garbage in the sedimentation tank 3, increase the frequency of cleaning the sedimentation tank 3, and affect the efficiency of greywater treatment.

[0030] like Figure 1 As shown, it also includes a disinfection mechanism 9, which is installed on the top of the base plate 1.

[0031] When in use, the disinfection unit 9 can disinfect the sewage.

[0032] like Figure 1 and Figure 3 As shown, the disinfection mechanism 9 is composed of a disinfection pool 901, a motor 902, a rotating shaft 903, and blades 904. The disinfection pool 901 is installed at the top of the base plate 1. The motor 902 is bolted to the outer wall of the disinfection pool 901. The rotating shaft 903 is installed at the output end of the motor 902. The rotating shaft 903 is located inside the disinfection pool 901. Blades 904 are welded to the shaft wall of the rotating shaft 903.

[0033] In use, when disinfecting the water after the membrane bioreactor 7, the water is pumped and transported to the disinfection tank 901 by the pump body 5. The disinfection mechanism 9 is installed on the top of the bottom plate 1. The disinfection mechanism 9 is composed of the disinfection tank 901, the motor 902, the rotating shaft 903 and the blades 904. When the sewage is transported to the disinfection tank 901, the personnel add disinfectant to the disinfection tank 901. The controller 4 controls the motor 902, so that the motor 902 drives the rotating shaft 903 at its output end to rotate. The rotating shaft 903 drives the blades 904 to rotate, so as to stir and mix the disinfectant in the disinfection tank 901 evenly and improve the disinfection efficiency of the sewage.

[0034] like Figure 1 As shown, a sedimentation tank 3 is installed at the top of the bottom plate 1, an anoxic tank 6 is installed at the top of the bottom plate 1, and a membrane bioreactor 7 is installed at the top of the bottom plate 1.

[0035] In operation, the wastewater is first settled in sedimentation tank 3, and then the biological organisms in the wastewater are oxidized in anaerobic tank 6. The principle of membrane bioreactor 7 is as follows: In the MBR system, microorganisms attach to the surface of the carrier to form a biofilm. These microorganisms use organic substrates to grow and reproduce, and gradually form a biochemically active biofilm on the surface of the carrier. The biofilm has a strong adsorption capacity and can further adsorb and decompose pollutants in the wastewater in the form of suspension, colloidal and dissolved substances. The microorganisms in the biofilm convert organic and inorganic substances into harmless substances such as carbon dioxide and water through metabolism.

[0036] like Figure 1 As shown, the disinfection tank 901, membrane bioreactor 7, anoxic tank 6 and sedimentation tank 3 are all connected by a pump body 5.

[0037] During use, the pump body 5 facilitates the step-by-step transportation of sewage.

[0038] like Figure 1As shown, a blower 8 is installed at the top of the base plate 1, and an exhaust pipe is installed at the output end of the blower 8. Two diversion pipes are welded to the wall of the exhaust pipe, and the diversion pipes are correspondingly inserted into the anoxic tank 6 and the membrane bioreactor 7.

[0039] During use, air is blown by blower 8, and the air enters the diversion pipe through the exhaust pipe. Then, air is blown into the anaerobic tank 6 and the membrane bioreactor 7 through the diversion pipe, so that the wastewater in the anaerobic tank 6 and the membrane bioreactor 7 is oxidized and impurities are removed.

[0040] like Figure 1 As shown, a controller 4 for controlling the electric telescopic rod 204, the blower 8, the motor 902, and the pump body 5 is installed on the outer wall of the sedimentation tank 3.

[0041] During use, the controller 4 can be used to conveniently control the electric telescopic rod 204, the blower 8, the motor 902, and the pump body 5.

[0042] In use, when wastewater is added to the sedimentation tank 3 for impurity removal, a pre-positioning mechanism 2 is installed on the top of the sedimentation tank 3. This mechanism 2 is composed of a frame 201, a honeycomb plate 202, a vertical plate 203, an electric telescopic rod 204, a scraper 205, a waste discharge trough 206, a sealing plate 207, a rubber pad 208, and a latch 209. After the wastewater is added to the frame 201, the honeycomb plate 202 welded inside the frame 201 blocks impurities in the wastewater, allowing it to pass through and enter the sedimentation tank. Inside the sedimentation tank 3, impurities are located at the top of the honeycomb panel 202. When too many impurities accumulate, personnel open the latch 209, rotate the sealing plate 207, and control the electric telescopic rod 204 via the controller 4. This causes the electric telescopic rod 204 to push the scraper 205, which moves at the honeycomb panel 202, allowing the impurities to be discharged through the impurity discharge trough. This prevents excessive impurities from entering the sedimentation tank 3, which would otherwise lead to excessive garbage in the sedimentation tank 3, increase the frequency of cleaning the sedimentation tank 3, and affect the efficiency of wastewater treatment. The wastewater is first settled in the sedimentation tank 3, and then the wastewater is further treated in the anoxic tank 6. The oxidation of pollutants in the membrane bioreactor 7 follows this principle: In the MBR system, microorganisms attach to the surface of the carrier to form a biofilm. These microorganisms utilize organic substrates to grow and reproduce, gradually forming a biochemically active biofilm on the carrier surface. The biofilm has a strong adsorption capacity, enabling it to further adsorb and decompose suspended, colloidal, and dissolved pollutants in the wastewater. The microorganisms within the biofilm convert organic and inorganic matter into harmless substances, such as carbon dioxide and water, through metabolism. During the disinfection of the water after the membrane bioreactor 7, pump 5 pumps the water... After the wastewater is transported into the disinfection tank 901, a disinfection mechanism 9 is installed on the top of the bottom plate 1. The disinfection mechanism 9 is composed of the disinfection tank 901, the motor 902, the rotating shaft 903, and the blades 904. When the wastewater is transported into the disinfection tank 901, the personnel add disinfectant into the disinfection tank 901 and control the motor 902 through the controller 4, so that the motor 902 drives the rotating shaft 903 at its output end to rotate. In turn, the rotating shaft 903 drives the blades 904 to rotate, so as to stir and mix the disinfectant in the disinfection tank 901 evenly and improve the disinfection efficiency of the wastewater.

[0043] The controller is an electrical control box, which contains a Siemens PLC control unit. A touch screen is installed on the door panel, and the output of the touch screen is electrically connected to the input of the PLC control unit. The inputs of the electric telescopic rod, blower, motor and pump are electrically connected to the output of the Siemens PLC controller, thereby realizing the control of the electric telescopic rod, blower, motor and pump.
