Description

Technical Field

[0001] The present invention relates to the field of domestic sewage treatment, and in particular to a cabinet-built-in domestic sewage treatment system and method. Background Art

[0002] A built-in domestic sewage treatment system is a compact, modular household sewage treatment device, usually installed under cabinets in kitchens and bathrooms. It is suitable for treating domestic sewage (such as washing water, kitchen wastewater, bath water, etc.). This type of system purifies sewage through physical, biological or chemical methods to ensure it meets discharge or reuse standards. It is particularly suitable for residential or small commercial places with limited space and no centralized drainage system.

[0003] For existing cabinet-mounted domestic sewage treatment systems, see Chinese Patent Publication No. CN117228879A, which details a small-scale domestic sewage treatment facility. The facility comprises a sequentially arranged sedimentation tank, an anaerobic tank, a biofilter, a secondary sedimentation tank, and a clear water tank. Domestic sewage from rural households passes through the sedimentation tank, intercepting particulate pollutants and scum, while undergoing anaerobic digestion to degrade some organic matter. The effluent from the anaerobic tank flows by gravity into the biofilter. The sedimentation and anaerobic tanks perform preliminary treatment on the sewage to prevent large suspended solids from entering the biofilter and causing clogging. They also perform preliminary removal of pollutants such as nitrogen, phosphorus, and organic matter. The sewage then flows into the biofilter for advanced treatment, and then enters the secondary sedimentation tank for sludge-water separation before being discharged. The sludge in the sedimentation and secondary sedimentation tanks is regularly cleaned and used as agricultural fertilizer. When the vegetable garden needs to be irrigated, the sewage from the anaerobic and secondary sedimentation tanks can be used. The clear water from the clear water tank can be used for laundry and vegetable washing, thus achieving sewage treatment and fully reusing water resources.

[0004] Although the existing miniaturized domestic sewage treatment system can effectively treat domestic sewage, it is unable to separate solid waste from sewage during the sewage treatment process. During long-term use, solid waste accumulates at the bottom of the device, which will reduce the efficiency of the device in treating sewage. Therefore, to address the above problems, a cabinet-built-in domestic sewage treatment system and method are proposed. Summary of the Invention

[0015] Preferably, a sewage treatment method for a cabinet-built-in domestic sewage treatment system comprises the following steps:

[0016] S1. Sewage enters the interior of the device body from the water inlet, solid waste is intercepted by the solid-liquid separation module, and sewage enters the interior of the device body;

[0017] S2. After sedimentation, the sewage is stratified, and the lighter grease floats on the water. The sewage and grease are separated and discharged through the oil-water separation module, and the grease is discharged from the oil outlet;

[0018] S3, the separated sewage comes into contact with the filler module inside the device body, and the organic matter in the sewage is decomposed by the microorganisms in the filler module;

[0019] S4. The treated sewage is discharged from the device body through the sewage outlet.

[0020] The present invention is beneficial in that:

[0021] 1. The present invention realizes the function of separating solid waste from sewage in domestic sewage through the structural design of the solid-liquid separation module, and solves the problem that although the existing miniaturized domestic sewage treatment system can effectively treat domestic sewage, it cannot separate solid waste from sewage during the sewage treatment process. During long-term use, solid waste accumulates at the bottom of the device, which will reduce the efficiency of the device in treating sewage. Most existing kitchen domestic sewage treatment devices directly crush solid waste and then discharge it into the sewer together with sewage. This treatment method will increase the treatment load of the sewage treatment plant. After long-term use, the residue of solid waste is easy to clog the pipe. The solid-liquid separation module can separate solid waste from sewage, which can effectively avoid the situation of pipe clogging after long-term use. By regularly dumping the solid waste, the treatment burden of the sewage treatment plant can be effectively reduced.

[0022] 2. The present invention utilizes an anti-aftertaste component designed to automatically open under the action of gravity when sewage enters the device through the water inlet, and automatically close when sewage is gone. This effectively prevents the odor of sewage from entering the home through the water inlet, keeping the air fresh.

[0023] 3. The present invention utilizes a dosing module designed to automatically release a chlorine tablet into the device when the collection basket is withdrawn from the device body. Automatic dosing of the device body can be achieved by regularly dumping solid waste from the collection basket. This reduces costs compared to conventional automatic dosing devices that utilize a combination of timers and motors for regular dosing. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Example

[0044] See also Figures 1-16As shown, the cabinet built-in domestic sewage treatment system and method include a device body 1; a water inlet 2 is provided at the top of the device body 1, a sewage outlet 3 is provided at the left side of the device body 1, and an oil outlet 4 is also provided at the left side of the device body 1. A solid-liquid separation module is provided inside the device body 1, and the solid-liquid separation module is used to separate solid waste in domestic sewage. A dosing module is provided at the front end of the solid-liquid separation module. An oil-water separation module is also provided inside the device body 1, and the oil-water separation module is used to separate grease and sewage in domestic sewage. The specific structure of the oil-water separation module can refer to the Chinese patent with publication number CN114504845B. The specific structure of the oil-water separation module in this case is similar to it, and the principle is the same as it. A filler module is provided at the bottom end of the device body 1. The components of the filler module can be specifically referred to the Chinese patent with publication number CN105130008B. The filler module is used to decompose organic matter in sewage; the solid-liquid separation module includes an anti-aftertaste component and a separation component Components, the anti-aftertaste component is provided inside the water inlet 2, the separation component is provided at the bottom end of the anti-aftertaste component, the anti-aftertaste component includes a check valve plate 31, the check valve plate 31 is rotatably connected to the inner wall of the water inlet 2, a torsion spring 32 is provided between the check valve plate 31 and the inner wall of the water inlet 2, a first mounting groove 33 is provided on the left side of the check valve plate 31, a first steel sheet 34 is fixedly connected to the inside of the first mounting groove 33, the first steel sheet 34 is attracted to the first magnetic block 35, and the first magnetic block 35 is attracted to the inner wall of the water inlet 2 The water inlet 2 is fixedly connected to the wall, one end of the torsion spring 32 is fixedly connected to the check valve plate 31, and the other end of the torsion spring 32 is fixedly connected to the inner wall of the water inlet 2. The separation assembly includes a collection basket 36, which is arranged inside the device body 1. The collection basket 36 is slidably connected to the slide rail 37, and the slide rail 37 is fixedly connected to the inner wall of the device body 1. A coarse filter plate 38 is fixedly connected to the inside of the collection basket 36. The coarse filter plate 38 is designed in a "V" shape. The bottom end of the collection basket 36 is fixedly connected to a fine filter plate 39;

[0045] During operation, sewage enters the interior of the device body 1 through the water inlet 2, and the sewage impacts the check valve plate 31, causing the check valve plate 31 to rotate downward, causing the first steel sheet 34 fixedly connected to the inside of the first mounting groove 33 and attracted to the first magnetic block 35 to separate from the first magnetic block 35 under the action of the impact force. As the check valve plate 31 rotates, the check valve plate 31 releases the obstruction to the sewage, and the sewage flows into the interior of the collection basket 36. When the check valve plate 31 rotates downward, it drives the fixedly connected torsion spring 32 to synchronously produce elastic deformation due to torsion. When the sewage stops flowing in, the impact force of the sewage on the check valve plate 31 disappears. At this time, the check valve plate 31 rotates to its original position under the action of the restoring force of the torsion spring 32, and drives the fixedly connected first steel sheet 34 to rotate synchronously to its original position and attract the first magnetic block 35, so that the water inlet 2 is sealed to prevent the odor of sewage from rising through the water inlet 2.

[0046] Furthermore, a movable groove 40 is formed at both the front and rear ends of the right side of the collection basket 36. A first spring 41 is provided inside the movable groove 40, and a fixed block 42 is inserted into the movable groove 40. The fixed block 42 engages with a fixed groove 43.

[0047] During operation, when sewage enters the interior of the collection basket 36, it first contacts the coarse filter plate 38. Through the mesh holes on the coarse filter plate 38, larger solid waste is retained on the coarse filter plate 38. Smaller solid waste continues to flow downward with the sewage and contacts the fine filter plate 39. The fine mesh holes on the fine filter plate 39 continue to intercept smaller solid waste, allowing only sewage to enter the interior of the device body 1. When the solid waste inside the collection basket 36 is excessively accumulated after long-term use, first pull the two sets of pulls. The movable plate 44 is used to make the pulling plate 44 drive the fixed block 42 to move synchronously inside the movable groove 40, release the engagement with the fixed groove 43 and squeeze the first spring 41, so that the first spring 41 produces elastic deformation. When the two sets of pulling plates 44 are released from the engagement with the fixed groove 43, the collecting basket 36 can be pulled to the right to remove the collecting basket 36 from the inside of the device body 1. After the collecting basket 36 is removed, the solid waste inside the collecting basket 36 is dumped, and the coarse filter plate 38 and the fine filter plate 39 are cleaned. After rinsing with clean water, it can be reinstalled into the interior of the device body 1 for use. When the collection basket 36 is to be installed, the collection basket 36 is first aligned with the slide rail 37, and then the collection basket 36 is inserted into the interior of the device body 1. When the collection basket 36 is inserted into the interior of the device body 1, the device body 1 squeezes the inclined surface on the fixing block 42, so that the fixing block 42 moves toward the inside of the movable groove 40 under the action of the squeezing force, and squeezes the first spring 41, so that the first spring 41 is elastically deformed under the action of the squeezing force. When the collection basket 36 is fully inserted into the interior of the device body 1, the squeezing force of the device body 1 on the fixing block 42 disappears. At this time, the fixing block 42 moves to its original position under the action of the restoring force of the first spring 41, and engages with the fixing block 42 to fix the collection basket 36. A sealing ring is provided at the joint between the collection basket 36 and the device body 1 for sealing to prevent the odor of sewage from escaping from the joint between the collection basket 36 and the device body 1 or sewage from overflowing from the joint.

After removing the top rod 46, the medicine storage box 49 is pulled upwards from the inside of the second mounting groove 45 to remove the medicine storage box 49 from the inside of the second mounting groove 45, and then the cover plate 50 is pulled upwards to separate the connecting block 51 fixedly connected to the cover plate 50 from the third magnetic block 53 fixedly connected to the inside of the connecting groove 52 to remove the connecting block 51, and then the finger is inserted into the interior of the medicine storage box 49 to move the front top block 72 backwards to drive the fixedly connected movable block 68 to move to the inside of the first receiving groove 67 to the limit, and the fourth spring 69 is squeezed. When the movable block 68 is completely inserted into the interior of the first receiving groove 67, the rear top block 62 moves backward synchronously with the front top block 72 under the action of the thrust. At this time, the second slider 65 slides in the interior of the second slide groove 63 and drives the third spring 66 to produce elastic deformation until the rear top block 62 is also pushed to the limit. A new chlorine tablet 61 is placed into the interior of the medicine storage box 49 and the front top block 72 is released to complete the replenishment of the chlorine tablet 61. At this time, the rear top block 62 moves forward under the action of the restoring force of the third spring 66, driving the front top block 72 to move synchronously. At the same time, the front top block 72 also moves forward under the action of the restoring force of the fourth spring 69 until it contacts the chlorine tablet 61, squeezing the chlorine tablet 61 and fixing it. The design of providing two sets of left positioning blocks 54 on the left side of the medicine storage box 49 and one set of right positioning blocks 55 on the right side has a fool-proof effect to avoid the situation of incorrect installation direction when installing the medicine storage box 49.
