Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment equipment, and more specifically, relates to an efficient intelligent biological treatment integrated reactor. Background Art

[0002] Membrane bioreactor (MBR) is a new type of water treatment technology that combines a membrane separation unit and a biological treatment unit. It replaces the secondary sedimentation tank with a membrane module to maintain a high activated sludge concentration in the biological reactor, reducing the land occupation of sewage treatment facilities, and reducing the sludge volume by maintaining a low sludge load. Compared with traditional biochemical water treatment technologies, the membrane bioreactor has the following main characteristics: high treatment efficiency, good effluent quality; compact equipment, small floor area; easy to achieve automatic control, simple operation and management.

[0003] During the application of the existing MBR membrane bioreactor, the membrane surface is easily contaminated by dirt, and it is necessary to frequently stop the machine for backwashing to remove the dirt on the surface of the MBR membrane element, resulting in a reduction in the overall purification efficiency. Taking a MBR membrane bioreactor (CN202311392752.2) disclosed in Chinese invention patent literature as an example, this invention shunts and treats the sewage by setting an electromagnet and a water distribution mechanism, so as to make full use of the filter membrane inside the reaction structure and avoid the blockage of the filter membrane. However, this invention only reduces the aggregation speed of dirt on the surface of the MBR membrane element by shunting, and does not solve the problem of frequently stopping the machine for backwashing to remove the dirt on the surface of the MBR membrane element.

[0004] Therefore, we need a biological treatment integrated reactor that can automatically clean the dirt on the surface of the MBR membrane element without stopping the machine. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient intelligent biological treatment integrated reactor, which has a simple structure and intelligent operation, can clean the membrane element without stopping the machine, improves the purification efficiency of sewage, and solves the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An efficient intelligent biological treatment integrated reactor of the present invention includes a reaction tank, a biological reactor, a water pump and a clean water tank; the reaction tank is filled with sewage to be purified, and the clean water tank is used to hold the purified sewage; the biological reactor is arranged inside the reaction tank, and the biological reactor is connected to the clean water tank through a water pump, and the sewage is pumped to the clean water tank through the water pump after being purified by the biological reactor.

[0008] The bioreactor includes a reactor body, several MBR membrane modules, and a cleaning unit; the MBR membrane modules are located on both sides inside the reactor body and are used to treat the contaminants in the sewage. The upper part of the reactor body is connected to a water pump through a pipeline. The cleaning unit is located in the middle inside the reactor body and is used to flush the contaminants attached to the surface of the MBR membrane modules to ensure the continuous use of the MBR membrane modules.

[0009] Several sewage outlets are provided on both sides of the reactor body and are used to discharge the attached contaminants flushed by the cleaning unit into the reaction tank, avoiding the accumulation of contaminants inside the bioreactor and affecting the purification efficiency of the bioreactor.

[0010] As a further improvement of the present invention, the reactor body includes a housing, a liquid outlet, and a pair of partition plates. The partition plates are located inside the housing and divide the inside of the housing into a cleaning chamber and a pair of reaction chambers; the cleaning unit is arranged inside the cleaning chamber, and the MBR membrane modules are arranged inside the reaction chambers; several through holes are opened on the outer side of the housing where the reaction chambers are located, and the liquid to be purified inside the reaction tank enters the bioreactor through the through holes. The liquid with attached contaminants flushed out by the cleaning unit inside the bioreactor also enters the reaction tank through the through holes.

[0011] As a further improvement of the present invention, the MBR membrane module is composed of multiple membrane modules and the biological sludge inside; the position of the MBR membrane module close to the middle of the reactor body is the outlet for filtered clear liquid.

[0012] As a further improvement of the present invention, the sewage outlet includes a sewage pipe, several limit blocks, and a sealing ball. The sewage pipe is fixedly connected to the side of the reactor body. A ball groove is opened in the middle of the sewage pipe. The diameter of the sealing ball is smaller than the inner diameter of the ball groove and larger than the inner diameter of the sewage pipe. The sealing ball can close the sewage pipe on the side close to the reactor body; the limit blocks are fixedly arranged on the side of the ball groove close to the outside and are used to support the sealing ball so as not to seal the sewage pipe on the side close to the outside, avoiding the sealing ball blocking the outflow path of the contaminants.

[0013] As a further improvement of the present invention, both sides inside the housing are arc-shaped plate surfaces. The cleaning ring moves with the piston to scrape the contaminants on the surface of the MBR membrane module to the area where the arc-shaped plate surface is located. Due to the arc-shaped design of the arc-shaped plate surface, when the piston pushes the liquid to impact the contaminants, the contaminants will be diverted to the sewage outlet through the arc-shaped plate surface.

[0014] As a further improvement of the present invention, the cleaning unit includes a motor, an eccentric wheel, a spring, a piston, several connecting rods, and a pair of cleaning rings. The cleaning rings are located on both sides of the piston and are fixedly connected to the piston through the connecting rods; the piston and the cleaning rings are located inside the reactor body and are slidably connected to the inner wall of the reactor body; the motor is arranged outside the reaction tank, and the output end penetrates the outer wall of the reaction tank and the reactor body and is detachably connected to the eccentric wheel; the eccentric wheel is located on one side of the piston and is in close contact with the piston; the spring is located on the other side of the piston and is used to support the piston to keep in close contact with the eccentric wheel, thereby driving the piston to reciprocate and slide to complete the cleaning of the two cleaning chambers on both sides.

[0015] As a further improvement of the present invention, a slope inclined towards the center of the cleaning ring is provided on the side of the cleaning ring away from the piston, and dirt will flow along the slope to the position of the through hole, so as to scrape the dirt on the surface of the MBR membrane module during the reciprocating sliding of the piston.

[0016] As a further improvement of the present invention, a sleeve is fixedly installed in the middle of one side of a partition plate close to the cleaning cavity to support the spring of the cleaning unit and prevent the spring from shifting.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging a cleaning unit inside the bioreactor, the dirt on the surface of the MBR membrane module can be cleaned while treating sewage, without stopping the machine and affecting the purification efficiency of sewage; by arranging a pair of partition plates inside the body to form a pair of reaction cavities, sewage can be continuously purified, improving the overall utilization rate of the equipment; by arranging a sealing ball inside the sewage discharge pipe, the piston can be used to drive the liquid flow to control the opening or closing of the sealing ball, achieving the effect of timely sewage discharge and ensuring the cleanliness inside the bioreactor; by controlling the reciprocating movement of the piston through the eccentric wheel and the spring, the liquid inside the reaction cavity can be driven to enter or flow out, so as to remove the dirt on the surface of the MBR membrane module through the impact of water flow.

Detailed Embodiments

[0025] Specific Embodiment 1: Please refer to Figures 1 - 5An efficient intelligent biological treatment integrated reactor, comprising a reaction tank 1, a biological reactor 2, a water pump 3 and a water purification tank 4; the reaction tank 1 contains the sewage to be purified, and the water purification tank 4 is used to hold the purified sewage; the biological reactor 2 is arranged inside the reaction tank 1, and the biological reactor 2 is communicated with the water purification tank 4 through the water pump 3. After being purified by the biological reactor 2, the sewage is pumped to the water purification tank 4 through the water pump 3.

[0026] The biological reactor 2 includes a reactor body 21, a number of MBR membrane modules 22 and a cleaning unit 23; the MBR membrane modules 22 are located on both sides inside the reactor body 21. The MBR membrane module 22 is an efficient combination of membrane separation technology and biological treatment method. It replaces the secondary sedimentation tank in the activated sludge method through membrane separation technology for solid-liquid separation, so as to treat the pollutants in the sewage; the upper part of the reactor body 21 is communicated with the water pump 3 through a pipeline, and the cleaning unit 23 is located in the middle inside the reactor body 21, and is used to wash the pollutants attached to the surface of the MBR membrane module 22 to ensure that the MBR membrane module 22 can be continuously used.

[0027] A number of sewage discharge ports 211 are provided on both sides of the reactor body 21, which are used to discharge the attached pollutants flushed by the cleaning unit 23 into the reaction tank 1, so as to avoid the accumulation of pollutants inside the biological reactor 2, causing blockage, and thus affecting the purification efficiency of the biological reactor 2.

[0028] Specifically, as Figure 3 shown, the reactor body 21 includes a housing 212, a liquid outlet 213 and a pair of partition plates 214. The partition plates 214 are located inside the housing 212 and divide the inside of the housing 212 into a cleaning chamber and a pair of reaction chambers; the cleaning unit 23 is arranged inside the cleaning chamber, and the MBR membrane module 22 is arranged inside the reaction chamber; a number of through holes 215 are opened on the outer side of the housing 212 where the reaction chamber is located. The liquid to be purified inside the reaction tank 1 enters the biological reactor 2 through the through holes 215, and the liquid with attached pollutants flushed out by the cleaning unit 23 inside the biological reactor 2 also enters the reaction tank 1 through the through holes, so as to ensure that pollutants do not deposit inside the biological reactor 2 and improve the service life of the biological reactor 2.

[0029] Specifically, the MBR membrane module 22 is composed of multiple membrane modules and the biological sludge inside; the position of the MBR membrane module 22 close to the middle of the reactor body 21 is the outlet for filtering clear liquid.

[0030] Specifically, as Figure 4The cleaning unit 23 shown includes a motor 231, an eccentric wheel 232, a spring 233, a piston 234, a plurality of connecting rods 235, and a pair of cleaning rings 236. The cleaning rings 236 are located on both sides of the piston 234 and are fixedly connected to the piston 234 through the connecting rods 235. The piston 234 is located inside the cleaning chamber, and the two cleaning rings 236 are respectively located inside the reaction chamber. Both the piston 234 and the cleaning rings 236 are slidably connected to the inner wall of the device body 21. The motor 231 is arranged outside the reaction tank 1, and the output end penetrates through the outer wall of the reaction tank 1 and the device body 21 and is detachably connected to the eccentric wheel 232. The eccentric wheel 232 is located on one side of the piston 234 and is in close contact with the piston 234. The spring 233 is located on the other side of the piston 234 and is used to support the piston 234 to keep in close contact with the eccentric wheel 232. When the large-diameter end of the eccentric wheel 232 abuts against the piston 234 under the drive of the motor 231, the spring 233 is compressed, and the piston 234 drives the cleaning ring 236 to move towards the side where the spring 233 is located. At this time, the cleaning ring 236 on the side where the spring 233 is located scrapes the dirt on the surface of the MBR membrane module 22 to the through hole 215 and the sewage discharge pipe 211 on the corresponding side. The cleaning ring 236 on the side far from the spring 233 returns to the position close to the partition plate 214 to prepare for subsequent scraping. At this time, the piston 234 divides the cleaning chamber into two chambers with large and small volumes. The water pump 3 extracts the purified water from the large-volume chamber and pumps it to the purified water tank 4. When the small-diameter end of the eccentric wheel 232 abuts against the piston 234 under the drive of the motor 231, the spring 233 resets and supports the piston 234 to slide towards the side where the eccentric wheel 232 is located. The cleaning ring 236 on the side close to the eccentric wheel 232 scrapes the dirt on the surface of the MBR membrane module 22 to the through hole 215 and the sewage discharge pipe 211 on the corresponding side. The cleaning ring 236 on the side far from the eccentric wheel 232 returns to the position close to the partition plate 214 to prepare for subsequent scraping. At this time, the piston 234 divides the cleaning chamber into two chambers with large and small volumes. The water pump 3 extracts the purified water from the large-volume chamber and pumps it to the purified water tank 4. As the piston 234 moves, it will push the liquid to flow back from the outlet of the filtered clear liquid of the MBR membrane module 22 to impact the dirt attached to the surface of the MBR membrane module 22, improving the dirt removal effect and realizing the continuous and efficient purification of sewage by the bioreactor 2.

[0031] Specifically, a slope inclined towards the center of the cleaning ring 236 is provided on the side of the cleaning ring 236 away from the piston 234, and the dirt will flow along the slope to the position of the through hole 215, so as to scrape the dirt on the surface of the MBR membrane module 22 during the reciprocating sliding of the piston 234.

[0032] Specifically, as Figure 5The sewage outlet 211 shown includes a sewage pipe 2111, several limiting blocks 2112 and a sealing ball 2113. The sewage pipe 2111 is fixedly connected to the side of the device body 21. A ball groove 2114 is formed in the middle of the sewage pipe 2111. The diameter of the sealing ball 2113 is smaller than the inner diameter of the ball groove 2114 and larger than the inner diameter of the sewage pipe 2111. The sealing ball 2113 can seal the sewage pipe 2111 on one side when the piston 234 moves away from the sewage pipe 2111 on that side; the limiting blocks 2112 are fixedly arranged on the side of the ball groove 2114 close to the outside, and are used to support the sealing ball 2113 when the piston 234 moves close to the sewage pipe 2111 on one side so as not to seal the sewage pipe 2111 on that side, preventing the sealing ball 2113 from blocking the outflow path of the dirt and ensuring that the dirt is smoothly discharged to the outside of the bioreactor 2.

[0033] Specifically, both sides inside the housing 212 are arc-shaped plate surfaces 2121. The cleaning ring 236 moves with the piston 234 to scrape the dirt on the surface of the MBR membrane module 22 to the area where the arc-shaped plate surface 2121 is located. Due to the arc-shaped design of the arc-shaped plate surface 2121, when the piston 234 pushes the liquid to impact the dirt, the dirt will be diverted to the sewage outlet 211 through the arc-shaped plate surface 2121.

[0034] Specifically, a sleeve 2141 is fixedly installed in the middle of one side of the partition 214 close to the cleaning cavity, which is used to support the spring 233 of the cleaning unit 23 and prevent the spring 233 from shifting.

[0035] During use, place the bioreactor 2 in the reaction tank 1 filled with sewage, and install the pipeline and the water pump 3 in sequence; turn on the water pump 3 and the motor 231. When the motor 231 drives the eccentric wheel 232 to rotate and the large-diameter end of the eccentric wheel 232 touches the piston 234, the spring 233 is compressed, and the piston 234 drives the cleaning ring 236 to move towards the side where the spring 233 is located. The cleaning ring 236 on the side where the spring 233 is located scrapes the dirt on the surface of the MBR membrane module 22 to the through hole 215 and the sewage pipe 211 on the corresponding side; when the small-diameter end of the eccentric wheel 232 touches the piston 234, the spring 233 resets and supports the piston 234 to slide towards the side where the eccentric wheel 232 is located. The cleaning ring 236 on the side close to the eccentric wheel 232 scrapes the dirt on the surface of the MBR membrane module 22 to the through hole 215 and the sewage pipe 211 at the corresponding arc-shaped plate surface 2121; the movement of the piston 234 divides the cleaning cavity into two chambers with large and small volumes. The water pump 3 pumps the purified water from the large-volume chamber and pumps it to the clean water tank 4; at the same time, the piston 234 will push the liquid to flow back from the outlet of the filtered clear liquid of the MBR membrane module 22 to impact the dirt attached to the surface of the MBR membrane module 22; at the same time, when the piston 234 pushes the liquid to move towards the sewage pipe 2111 on one side, the limiting block 2112 supports the sealing ball 2113 to prevent the sewage pipe 2111 on that side from being sealed, ensuring that the dirt can flow out from the gap between the sealing ball 2113 and the limiting block 2112 and ensuring the efficient operation of the bioreactor 2.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
