Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to industrial organic wastewater treatment equipment. Background Art

[0002] With the rapid development of industry, the discharge of industrial organic wastewater is increasing. If it is discharged directly without effective treatment, it will cause serious damage to the ecological environment such as water bodies and soil, and will also threaten human health. Efficient treatment of industrial organic wastewater can not only reduce the risk of environmental pollution and protect the ecological balance, but also realize the recycling of water resources and alleviate the pressure of water shortage.

[0003] Membrane bioreactors combine membrane separation technology with biological treatment processes. They utilize the membrane's efficient interception effect to retain microorganisms such as activated sludge within the reactor, achieving sludge-water separation. They can effectively remove pollutants such as organic matter and ammonia nitrogen from wastewater, with high treatment efficiency. They are one of the commonly used treatment equipment for industrial wastewater treatment, such as the wastewater treatment membrane bioreactor disclosed in patent publication number CN105000661B. The membrane bioreactor is mainly composed of a biological treatment unit and a membrane separation unit. In the biological treatment unit, activated sludge plays a role in decomposing and purifying organic wastewater. After completing the biological treatment, the water enters the membrane separation unit, and the membrane elements are laid flat or arranged. When the wastewater flows in, the membrane elements near the overflow port will first and directly contact the wastewater containing activated sludge. This causes the amount of activated sludge attached to the membrane elements in this area to far exceed that far from the overflow port. On the one hand, excessive activated sludge attachment will accelerate membrane fouling, increase the filtration resistance of the membrane, reduce the membrane flux, and shorten the service life of the membrane elements in this area. On the other hand, due to the large differences in the environment of membrane elements at different positions, the treatment efficiency of the entire membrane separation unit will be uneven, affecting the overall purification effect of the wastewater, and thus it is difficult to stably achieve the expected effluent water quality standards. At the same time, the direct impact of wastewater on the membrane elements may increase the adhesion of activated sludge to the surface of the membrane elements, which is not conducive to the subsequent cleaning of the attached activated sludge.

The drive motor 95 and the electromagnetic clutch 96 are both electrically connected to the control cabinet 3.

When the electromagnetic clutch 96 is powered off, the drive motor 95 cannot drive the rotating rod 81 to rotate.

[0022] The clearing unit 11 is arranged above the roller sleeve 7. The clearing unit 11 is used to clear the membrane separation unit 8. The clearing unit 11 includes a support frame 111 fixedly installed on one side of the top of the separation tank 2. The support frame 111 is equipped with multiple electric push rods 112, and the telescopic ends of each electric push rod 112 are fixedly connected to an arc-shaped pressure plate 113. The bottom of the arc-shaped pressure plate 113 is provided with multiple air grooves 114 matching the water inlet groove 84. An air pump 115 is fixedly installed on the top of the arc-shaped pressure plate 113, and an air pipe 116 is installed at the air outlet end of the air pump 115. A hollow column 117 is fixedly installed on the wall of the air pipe 116. A plurality of pressure pipes 118 are fixedly connected to the lower side wall of the hollow column 117, and a clearing electric control valve 119 is installed inside each pressure pipe 118. The tube walls of the support tubes 85 are fixedly connected with an air intake assembly 15 that matches the pressure tube 118. The airflow delivered by the air pump 115 enters the corresponding support tube 85 through the pressure tube 118 and the corresponding air intake assembly 15. The air pump 115 and the clearing electric control valve 119 are electrically connected to the control cabinet 3.

The elastic support assembly 155 includes an elastic element, a fixed component and a movable rod. When the electromagnetic component 152 is energized to attract the circular iron block 154 to move upward, the elastic element is compressed. When the electromagnetic component 152 is de-energized, the elastic element rebounds and recovers, so that the circular iron block 154 is against the support ring 153.

[0024] The sludge extraction mechanism 12 is arranged at the lower end of the side wall of the separation tank 2, and is used to extract the activated sludge inside the separation tank 2.

A valve is also provided at the bottom of the U-shaped trough plate 4, which is used to discharge the sludge accumulated in the U-shaped trough plate 4 into the overflow channel 5. The sludge pump can extract the activated sludge and transport a part of it to the biological treatment tank 1 through the sludge conveying pipeline, and the other part is directly discharged for subsequent treatment. The detection component 14 includes a mounting bracket 141 fixedly mounted on the outer wall of the separation tank 2, and an encoder 142 is installed on the side wall of the mounting bracket 141. The shaft end of the encoder 142 is transmission-connected to the rod end of the drive rod 92. The encoder 142 is used to detect the rotation angle of the drive rod 92 and convert the rotation angle into an electrical signal to feed back to the control cabinet 3.

[0025] The operating principle of the present invention is now described as follows: wastewater is mixed with activated sludge in the biological treatment tank 1, and the microorganisms in the activated sludge decompose and purify the organic matter in the wastewater. As the wastewater in the biological treatment tank 1 increases, when the water level reaches the overflow inlet 6, the wastewater will enter the overflow channel 5 through the overflow inlet 6, and the wastewater will flow along the overflow channel 5, and the activated sludge will settle. When the wastewater enters the overflow channel 5, when the wastewater falls, the wastewater will impact the impeller 93, thereby rotating the driving rod 92, and the driving rod 92 will drive the rotating rod 81 to rotate through the chain transmission assembly 94, and the rotating rod 81 will drive the roller sleeve 7 to rotate through the mounting sleeve 82 and the support pipe 85, thereby driving each arc membrane element 86 to rotate synchronously. As the wastewater entering the separation tank 2 increases, the water level will reach the position of the overflow return outlet 10. At this time, the wastewater The water will be discharged back into the U-shaped trough plate 4 through the overflow return port 10. As the water level inside the U-shaped trough plate 4 becomes higher and higher, when the water level reaches the position of the rotating rod 81, the water will enter the water inlet trough 84 through the arc-shaped membrane element 86 on the lower side of the roller sleeve 7 under the action of pressure. The arc-shaped membrane element 86 can intercept impurities such as activated sludge inside the U-shaped trough plate 4. As the roller sleeve 7 rotates, the arc-shaped membrane element 86 will impact the wastewater discharged from the overflow return port 10. Under the action of shear force, the activated sludge on the surface of the arc-shaped membrane element 86 will be impacted and separated from the arc-shaped membrane element 86, thereby reducing the possibility of activated sludge clogging the arc-shaped membrane element 86. The water entering the water inlet trough 84 will enter the drainage trough 87 through the support pipe 85, the installation sleeve 82 and the water inlet hole 88, and finally be discharged to the subsequent process through the detection box 131 and the drainage pipe 133. During the rotation of the driving rod 92, the encoder 142 will detect the number of rotations of the driving rod 92 and convert the rotation angle into an electrical signal to feed back to the control cabinet 3. Every time the driving rod 92 rotates 360°, the metering module in the control cabinet 3 will measure the number of rotations of the driving rod 92 once. When the measured number of rotations reaches a certain value (the number of rotations can be set through the control cabinet 3 according to factors such as the concentration of organic wastewater, for example, set to 100 rotations), the control cabinet 3 will start the blockage clearing operation. At this time, the control cabinet 3 will control the electromagnetic clutch 96 to work. After the electromagnetic clutch 96 is energized, it can effectively transmit the driving force of the driving motor 95 to the rotating rod 81. At the same time, the control cabinet 3 will control the driving motor 95 to work, and the driving motor 95 drives the electromagnetic clutch 96. The rotating rod 81 rotates actively, and the rotating rod 81 can drive the driving rod 92 to rotate. At this time, the rotating angle of the driving rod 92 is detected by the encoder 142. When the rotation angle of the driving rod 92 returns to zero, the control cabinet 3 controls the driving motor 95 to stop working. At this time, each arc-shaped membrane element 86 on one side is on the upper side of the roller sleeve 7. Then, the control cabinet 3 controls each electric push rod 112 to perform timing work. The electric push rod 112 will push the arc-shaped pressure plate 113 downward. When the timing work of the electric push rod 112 is completed, the arc-shaped pressure plate 113 will be sealed against the top of the roller sleeve 7. At this time, each pressure tube 118 will also be against the corresponding L-shaped tube 151. Then, the control cabinet 3 controls the electromagnetic parts 152 in each pressure tube 118 to energize and work. The magnetic piece 152 is energized to generate a magnetic attraction force on the circular iron block 154, thereby attracting the circular iron block 154 to move upward. At this time, the annular openings of each support ring 153 are opened. Subsequently, the control cabinet 3 controls the clearing electric control valves 119 in each pressure pipe 118 on the upper side to be energized and opened, and controls the air pump 115 to start working. The air pump 115 will transport air to each support pipe 85 through each pressure pipe 118 and each L-shaped pipe 151. Since the installation sleeve 82 is filled with water, the air flow can only enter the water inlet trough 84 on the same side through the support pipe 85, and be discharged from the inside of the arc membrane element 86 to the outside. The arc membrane element 86 is back-blown by the air flow, which can clean the activated sludge and other impurities that may be attached to the outer surface of the arc membrane element 86. When the air pump 1 After working for 20 seconds, the control cabinet 3 controls the air pump 115, the electromagnetic component 152 and each clearing electric control valve 119 to stop working, and controls the arc pressure plate 113 to move back and reset through the electric push rod 112. Subsequently, the drive motor 95 is controlled to drive the roller sleeve 7 to rotate a certain angle, so that the next group of arc-shaped membrane elements 86 rotate to the top of the roller sleeve 7, and then the above steps are repeated to clear the blockage of each arc-shaped membrane element 86. When all the arc-shaped membrane elements 86 are cleared, the control cabinet 3 controls the electromagnetic clutch 96, the drive motor 95, the clearing electric control valve 119, the electromagnetic component 152, etc. to cut off the power, and controls the electric push rod 112 to drive the arc pressure plate 113 to move back and reset. Then, the control cabinet 3 controls its own metering module to reset the count of the encoder 142.The electric signal fed back by the encoder 142 is counted again. As the amount of overflowing wastewater increases or the amount of activated sludge in the wastewater increases, the arc-shaped membrane element 86 will be more likely to be blocked and contaminated due to the increase in the amount of wastewater treated and the increase in the amount of contact with the activated sludge. At this time, the impeller 93 drives the driving rod 92 to rotate faster, and the metering speed of the metering module of the control cabinet 3 is synchronously increased, thereby shortening the interval time for clearing the blockage of the arc-shaped membrane element 86, ensuring the timeliness of clearing the blockage of the arc-shaped membrane element 86, and reducing the possibility of damage to the arc-shaped membrane element 86. Among them, when the separated water is discharged into the detection box 131 through the drainage trough 87, the turbidity detection probe 132 will detect the turbidity of the wastewater flowing through by emitting light and measuring the intensity of the received light. When the turbidity exceeds the threshold (the threshold can be set by the control cabinet 3, for example, set to 5NTU), the turbidity detection probe 132 will feedback an electrical signal to the control cabinet 3. At this time, the control cabinet 3 will control the shunt normally closed solenoid valve 135 and the drainage normally open solenoid valve 136 to energize and simultaneously control the pump to pump back to the input component 1 37 works. At this time, the wastewater discharged into the drainage pipe 133 will be discharged through the shunt pipe 134 and pumped back into the biological treatment tank 1 by the pump return assembly 137 to prevent the wastewater with excessive turbidity from being directly discharged (wherein, the pump return assembly 137 includes at least a water pump, a return pipeline, a check valve, a junction box and other components. The water discharged from the shunt pipe 134 enters the junction box, and the water in the junction box is pumped out by the water pump and returned to the biological treatment tank 1 through the return pipeline. The check valve can prevent the wastewater in the biological treatment tank 1 from flowing back into the return pipeline). Secondly, when the turbidity detection probe 132 feeds back an electrical signal to the control cabinet 3, it indicates that some of the arc-shaped membrane elements 86 may be damaged, etc., resulting in a deterioration in the filtering effect of the arc-shaped membrane elements 86 on impurities such as activated sludge, thereby increasing the turbidity of the discharged water. Therefore, after the control cabinet 3 receives the electrical signal fed back by the turbidity detection probe 132, the control cabinet 3 will start the leakage detection work. At this time, the control cabinet 3 will return the roller sleeve 7 to its original position according to the above steps, that is, one group of arc-shaped membrane elements 86 is directly above the roller sleeve 7. Subsequently, according to the above steps, the arc-shaped pressure plate 113 is pressed against the roller sleeve 7, and then the control cabinet 3 will start the leakage detection work. Cabinet 3 controls the detection electric control valve 162 in each detection tube 161 in sequence from front to back to start, and then controls the air pump 115 to work. The air pump 115 will convey air into the detection tube 161 where the detection electric control valve 162 is energized and opened through the hollow column 117. The air flow will enter the inside of the air groove 114, and then the air flow will pass through the arc-shaped membrane element 86 on this side and enter the support tube 85 on this side. When the arc-shaped membrane element 86 on this side is damaged, the air flow channel at the arc-shaped membrane element 86 becomes larger, so the air flow discharge speed becomes faster. When the arc-shaped membrane element 86 is not damaged, the air flow discharge is greatly restricted and the discharge speed is slow. At this time, the air pressure inside the air tank 114 will be too high, so the air pressure detection probe 163 on this side will detect the increase in air pressure and feedback an electrical signal to the control cabinet 3 after the air pressure rises to the threshold value. The control cabinet 3 receives the feedback electrical signal from the air pressure detection probe 163 within 5 seconds of the operation of the air pump 115, which means that the arc-shaped membrane element 86 is not damaged. Otherwise, it means that the arc-shaped membrane element 86 is damaged. After the detection of the arc-shaped membrane element 86 on one side is completed (that is, after the air pump 115 has been operating for 5 seconds), the control cabinet 3 controls the detection electric control valve 162 on this side to cut off the power and immediately controls the next arc-shaped membrane element 86 The detection electric control valve 162 at is energized and opened, and then the next arc membrane element 86 is tested for leakage. When all the arc membrane elements 86 on the upper side are tested, the control cabinet 3 controls the drive motor 95 to rotate the roller sleeve 7 by a certain angle, and then repeats the steps to test the arc membrane elements 86 until the leakage detection of all the arc membrane elements 86 is completed. Among them, when the arc membrane element 86 is detected to be damaged, the control cabinet 3 will record the number corresponding to the arc membrane element 86 (each arc membrane element 86 corresponds to a number), and the subsequent staff can check the number and replace the damaged arc membrane element 86.
