Description

A rural sewage low-carbon treatment system and treatment process Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a rural sewage low-carbon treatment system and a treatment process thereof. Background Art

[0002] Rural sewage includes domestic wastewater (fecal and urine wastewater, laundry water, kitchen water, etc.) and industrial wastewater (from individual livestock and poultry farms and small workshops). Therefore, rural non-point source pollution is caused by the direct discharge of untreated domestic and industrial wastewater into rivers and soil. Fecal and urine wastewater in rural domestic sewage varies depending on region and economic development. Currently, sewage treatment plants are widely used to treat wastewater. However, most sewage treatment plants are unable to treat fecal coliform bacteria in human and animal feces and are not environmentally friendly. Patents have been filed to address this issue.

[0003] For example, Chinese patent CN210683413U discloses a low-carbon and environmentally friendly rural sewage treatment device, which relates to the field of sewage treatment technology. The low-carbon and environmentally friendly rural sewage treatment device comprises a base, wherein the upper surface of the base is fixedly connected to a filter box and a support column, wherein the filter box is fixedly connected to a treatment box on the side away from the base, wherein a placement box is fixedly connected to one side of the treatment box, wherein one side of the placement box is fixedly connected to the support column, and wherein a first sealed bearing is fixedly connected to the interior of the treatment box on the side close to the placement box. The low-carbon and environmentally friendly rural sewage treatment device has a medicine storage box on the top of the treatment box, wherein chlorine-free disinfectant powder is placed inside the medicine storage box, which can kill fecal coliform bacteria in the sewage inside the treatment box, can reduce diseases, and achieve the purpose of sterilization. A water filter bag is provided inside the filter box, which can filter and collect large particles in the sewage, so that it can be used as fertilizer or other materials after later treatment, thus achieving the purpose of low carbon and environmental protection.

[0004] Although the above document achieves the function of disinfecting and filtering wastewater by setting a medicine box on the top of the device and installing a filter belt at the bottom of the device, it has obvious defects in actual use, such as:

[0005] Although the medicine box can be used for drug administration, it requires manual loading after each administration. In addition, it cannot be used for quantitative dosage and needs to be weighed in advance before being put in, making it too cumbersome to use.

[0006] A mesh bag is installed under the equipment. Although it can filter out large particles of impurities, this method can easily cause the mesh bag to become clogged, affecting the discharge of sewage. It is also difficult to clean the inside, resulting in poor equipment hygiene.

[0007] Therefore, a rural sewage low-carbon treatment system that can automatically dose and easily clean is designed to solve this problem. Summary of the Invention

[0017] The present invention also discloses a low-carbon treatment process for rural sewage, which specifically comprises the following steps:

[0018] S1. Before use, the flocculant is placed inside the medicine storage box. The flocculant is injected into one of the medicine storage tanks that overlaps with it through the medicine dispensing port. The movable seat blocks the bottom of the medicine storage tank through the L-shaped sealing plate to prevent the flocculant from leaking. After the medicine is added, the process proceeds to step S2 for sewage treatment.

[0019] S2, wastewater is injected into the water receiving tank. At this time, the water pipe on the right is blocked by the water sealing plate. The wastewater can only flow into the inner side of the second water storage tank through the water pipe on the right. The large garbage in the wastewater is filtered out by the filter plate, and the wastewater directly accumulates in the inner cavity of the second water storage tank. When the wastewater accumulates too much, the circular buoyancy plate and the top rod are pushed up and the button on the top is pressed. After the button is triggered, the water pipe at the bottom is opened, and the wastewater inside the second water storage tank flows into the inner side of the sedimentation tank through the water pipe. After the wastewater inside the second water storage tank drops a certain distance, the cylinder is delayed to open. After the cylinder is opened, it pushes the first tooth plate to rise and drives the gear barrel to rotate. When the gear barrel rotates, it will drive the tooth rod and the second tooth plate to move at the same time. The second tooth plate moves to the filter inside the second water storage tank. The plate is pushed out from the inner side of the second water storage tank, and the filter plate on the left is pushed into the inner side of the first water storage tank. The movement of the second tooth plate drives the moving seat to move, and the medicine storage tank just below the medicine discharging port is moved out of the L-shaped sealing plate. The flocculant inside the medicine storage tank falls on the inner side of the sedimentation tank through the medicine feeding frame, and the other empty medicine storage tank overlaps with the moving seat, and the flocculant inside the medicine storage tank falls on the inner side of the empty medicine storage tank. Since the second tooth plate has a small number of teeth, after the second tooth plate moves to the limit distance, the counterclockwise rotation of the gear cylinder no longer engages the second tooth plate. When the cylinder continues to rise, it will push the top plate so that the vertical rod pushes the two water sealing plates to rise, so that the left water pipe is opened and the right water pipe is closed, and the wastewater enters the first water storage tank, and then goes to step S3 for the sedimentation process;

[0020] S3. After the wastewater enters the sedimentation tank, the delayed motor starts and drives the rotating rod to rotate. After the stirring blade is driven, the wastewater is stirred to disperse the flocculant evenly. At the same time, the second bevel gear drives the first bevel gear to rotate, so that the reciprocating screw also rotates at the same time. The brush plate moves back and forth through the threaded sleeve and the limit rod. The brush plate sweeps the garbage on the top of the threaded sleeve and stops after the motor is fully started. The brush plate returns to its original position. At this time, the wastewater in the sedimentation tank is left to stand. After the sedimentation is completed, the solenoid valve is opened to discharge the wastewater. The flocculant filter frame filters out the flocculants. At this time, the wastewater flows into the first water storage tank through the water receiving tank. After the wastewater inside the first water storage tank is full, the button is triggered and the S2 step is repeated again to switch.

[0021] Preferably, in the step S2, after the second tooth plate moves to the limit distance, the counterclockwise rotation of the gear barrel no longer meshes with the second tooth plate, and the gear barrel will mesh with the second tooth plate again when it rotates clockwise to drive the reset.

[0022] The present invention provides a rural sewage low-carbon treatment system and treatment process. Compared with existing technologies, it has the following advantages:

[0023] (1) The rural sewage low-carbon treatment system is equipped with a water filtering mechanism and a sedimentation mechanism that cooperate with each other on the top of the bottom plate. The first water tank and the second water tank can be used interactively. When the button is triggered, the lifting of the cylinder can simultaneously complete the working switch of the first water tank and the second water tank, displacing the two filter plates for easy cleaning, and can also drive the moving seat to move left and right to realize the function of quantitative dosing. The process is simple and can effectively reduce manual operation. In addition, only two sets of driving sources are used to achieve multiple linkage effects, so that it can carry out uninterrupted and continuous sewage treatment, improve sewage treatment efficiency, and meet the current low-carbon concept.

[0024] (2) The rural sewage low-carbon treatment system is provided with an L-shaped sealing plate installed at the bottom of the medicine storage box, and a movable seat is slidably installed on the inner side of the L-shaped sealing plate. At the same time, two medicine storage tanks are provided on the top of the movable seat for use with the medicine discharge port. Driven by the rotation of the gear cylinder, the medicine storage tanks can be automatically filled with a certain amount of medicine and subsequently the sedimentation box can be fed in each back and forth movement of the movable seat, which is convenient for the use of the staff.

[0025] (3) The rural sewage low-carbon treatment system has a toothed rod connected to the surface of the connecting rod and is used in conjunction with the gear cylinder. After the gear cylinder rotates, the two filter plates can be switched, and the filter plate with garbage can be moved out. Then, the forward and backward movement of the brush plate can effectively remove the garbage on the top of the filter plate, making it easy to clean and ensuring the cleanliness of the equipment.

[0026] (4) The rural sewage low-carbon treatment system is provided with two offset water sealing plates on the inner side of the tooth rod, and is used in conjunction with the cylinder through the vertical rod and the top plate. The two water pipes can be switched every time the cylinder is raised or lowered, thereby preventing sewage from flowing into the first water tank or the second water tank on the other side that is not working, thereby improving the functionality of the equipment.

[0046] The present invention also discloses a low-carbon treatment process for rural sewage, which specifically comprises the following steps:

[0047] S1. Before use, the flocculant is placed inside the medicine storage box 303. The flocculant is injected into one of the overlapping medicine storage tanks 307 through the medicine dispensing port 306. The movable seat 305 blocks the bottom of the medicine storage tank 307 through the L-shaped sealing plate 304 to prevent the flocculant from leaking. After the flocculant is injected, the process proceeds to step S2 for the sewage treatment process.

[0048] S2. Wastewater is injected through the water receiving tank 218. At this time, the water pipe 217 on the right is blocked by the water sealing plate 220. The wastewater can only flow into the inner side of the second water storage tank 202 through the water pipe 217 on the right. The large garbage in the wastewater is filtered out by the filter plate 204. The wastewater is directly accumulated in the inner cavity of the second water storage tank 202. When the wastewater accumulates too much, the circular buoyancy plate 225 and the top rod 224 are pushed up to press the button 226 on the top. After the button 226 is triggered, the water pipe 223 at the bottom is opened. The wastewater from the opened second water tank 202 flows into the inside of the sedimentation tank 301 through the water pipe 223. After the wastewater from the second water tank 202 drops a certain distance, the cylinder 209 is opened with a delay. After the cylinder 209 is opened, it pushes the first tooth plate 210 upward to push the gear cylinder 207 to rotate. When the gear cylinder 207 rotates, it simultaneously drives the tooth rod 208 and the second tooth plate 309 to move. The second tooth plate 309 moves to the filter plate 201 inside the second water tank 202. 4 is pushed out from the inner side of the second water storage tank 202, and the filter plate 204 on the left is pushed into the inner side of the first water storage tank 201. The movement of the second tooth plate 309 drives the movable seat 305 to move, and the medicine storage tank 307 directly below the medicine dispensing port 306 is moved out of the L-shaped sealing plate 304. The flocculant in the medicine storage tank 307 falls into the inner side of the sedimentation box 301 through the medicine feeding frame 302, and the other empty medicine storage tank 307 overlaps with the movable seat 305. The flocculant in the medicine storage box 303 falls into the empty medicine storage tank 307. The second tooth plate 309 has a small number of teeth. After the second tooth plate 309 moves to the limit distance, the counterclockwise rotation of the gear cylinder 207 no longer engages the second tooth plate 309. When the cylinder 209 continues to rise, it pushes the top plate 222 so that the vertical rod 219 pushes the two water sealing plates 220 to rise, so that the left water pipe 217 is opened and the right water pipe 217 is closed, and the wastewater enters the first water storage tank 201. Then, the process goes to step S3 for sedimentation.

[0049] S3, after the wastewater enters the sedimentation box 301, the delayed motor 311 is started to drive the rotating rod 312 to rotate, and the stirring blade 314 is driven to stir the wastewater to evenly disperse the flocculant. At the same time, the second bevel gear 313 drives the first bevel gear 213 to rotate, so that the reciprocating screw rod 212 also rotates at the same time, and the brush plate 215 moves back and forth through the threaded sleeve 214 and the limiting rod 216. The brush plate 215 sweeps away the garbage on the top of the threaded sleeve 214, and stops after the motor 311 is fully started, and the brush plate 215 returns to its original position. At this time, the sedimentation box 3 01 is allowed to stand, and after the sedimentation is completed, the solenoid valve 316 is opened to discharge the wastewater, and the flocculant filter frame 319 filters out the flocculants. At this time, the wastewater flows into the first water tank 201 through the water receiving tank 218. After the wastewater inside the first water tank 201 is full, the button 226 is triggered and the S2 step is repeated again to switch. In the S2 step, after the second tooth plate 309 moves to the limit distance, the counterclockwise rotation of the gear cylinder 207 does not mesh with the second tooth plate 309. When the gear cylinder 207 rotates clockwise, it will mesh with the second tooth plate 309 again to drive it to reset.

9. A low-carbon treatment process for rural sewage, characterized by: The specific steps include: S1. Before use, a flocculant is placed inside the medicine storage box (303), and the flocculant is injected into the inside of one of the medicine storage tanks (307) that overlaps with the medicine storage tank (307) through the medicine dispensing port (306). The movable seat (305) blocks the bottom of the medicine storage tank (307) through the L-shaped sealing plate (304) to prevent the flocculant from leaking out. After the medicine is injected, the process proceeds to step S2 to perform the sewage treatment process. S2. Wastewater is injected through the water receiving box (218). At this time, the water pipe (217) on the right side is blocked by the water sealing plate (220). The wastewater can only flow into the inner side of the second water storage tank (202) through the water pipe (217) on the right side. Large garbage in the wastewater is filtered out by the filter plate (204). The wastewater is directly accumulated in the inner cavity of the second water storage tank (202). When too much wastewater is accumulated, the circular buoyancy plate (225) and the top rod (224) are pushed up to press the button (226) on the top. After the button (226) is triggered, the water pipe (223) at the bottom is opened. The wastewater in the second water storage tank (202) flows into the inside of the sedimentation tank (301) through the water pipe (223). After the wastewater in the second water storage tank (202) drops a certain distance, the cylinder (209) is delayed to open. After the cylinder (209) is opened, it pushes the first tooth plate (210) to rise and drives the gear cylinder (207) to rotate. When the gear cylinder (207) rotates, it drives the tooth rod (208) and the second tooth plate (309) to move at the same time. The second tooth plate (309) moves to the filter plate (204) in the second water storage tank (202). ) is pushed out from the inner side of the second water storage tank (202), while the filter plate (204) on the left is pushed into the inner side of the first water storage tank (201), and the movement of the second tooth plate (309) drives the movable seat (305) to move, so that the medicine storage tank (307) directly below the medicine dispensing port (306) is moved out of the L-shaped sealing plate (304), and the flocculant inside the medicine storage tank (307) falls to the inner side of the sedimentation box (301) through the medicine dispensing frame (302), while the other empty medicine storage tank (307) overlaps with the movable seat (305), and the flocculant inside the medicine storage box (303) falls On the inner side of the vacant medicine storage tank (307), the second tooth plate (309) has a small number of teeth. After the second tooth plate (309) moves to the limit distance, the counterclockwise rotation of the gear cylinder (207) no longer meshes and rotates the second tooth plate (309). When the cylinder (209) continues to rise, it pushes the top plate (222) so that the vertical rod (219) pushes the two water sealing plates (220) to rise, so that the left water pipe (217) is opened and the right water pipe (217) is closed, and the wastewater enters the first water storage tank (201), and then turns to step S3 for sedimentation process; S3. After the wastewater enters the sedimentation box (301), the delayed motor (311) is started to drive the rotating rod (312) to rotate. The stirring blade (314) is driven to stir the wastewater to evenly disperse the flocculant. At the same time, the second bevel gear (313) drives the first bevel gear (213) to rotate, so that the reciprocating screw (212) also rotates at the same time. The brush plate (215) moves back and forth through the threaded sleeve (214) and the limiting rod (216). The brush plate (215) moves the threaded sleeve (214) back and forth. 4) Sweeping the garbage on the top, the motor (311) stops after the motor (311) has fully started, and the brush plate (215) returns to its original position. At this time, the wastewater in the sedimentation tank (301) is left to stand. After sedimentation is completed, the solenoid valve (316) is opened to discharge the wastewater, and the flocculant filter frame (319) filters out the flocculants. At this time, the wastewater flows into the first water storage tank (201) through the water receiving tank (218). When the wastewater inside the first water storage tank (201) is full, the button (226) is triggered and step S2 is repeated again to switch.

10. A low-carbon treatment process for rural sewage according to claim 9, characterized in that: In the step S2, after the second tooth plate (309) moves to the limit distance, the counterclockwise rotation of the gear cylinder (207) no longer meshes with the second tooth plate (309), and the gear cylinder (207) rotates clockwise to mesh with the second tooth plate (309) again to drive the reset.
