Description

Technical Field

[0001] The invention relates to the field of reactors, and in particular to an anaerobic ammonia oxidation reactor and a process for treating high-ammonia nitrogen coal-to-oil wastewater. Background Art

[0002] With the rapid development of industry, the treatment of many industrial wastewaters has become a major problem, especially for nitrogen-containing wastewater. In particular, high-concentration nitrogen-containing wastewater is extremely difficult to treat. Even if the final effluent meets the standards, it still requires a high treatment cost. Among the current methods for treating nitrogen-containing wastewater, the main method is anaerobic ammonia oxidation technology. Under anaerobic conditions, anaerobic ammonia oxidation bacteria simultaneously convert ammonia nitrogen and nitrite nitrogen in sewage into nitrogen gas. Anaerobic ammonia oxidation technology has the advantages of saving carbon sources, saving costs, and producing less sludge.

[0003] According to existing data, the activity of anaerobic ammonium oxidizing bacteria is closely related to the pH value in which they are located. In the pH range of 8.0-8.4, anaerobic ammonium oxidizing bacteria can maintain a high activity, which is the optimal condition for its ammonia nitrogen conversion reaction. In the prior art, anaerobic ammonium oxidation reactors generally cannot adjust the pH value of wastewater, which makes it inconvenient to adjust the pH value of wastewater to the optimal range. At this time, anaerobic ammonium oxidizing bacteria cannot guarantee a high activity, which makes the reaction rate of converting ammonia nitrogen and nitrite nitrogen into nitrogen gas at the same time slow, which makes the denitrification treatment effect of wastewater poor.

[0064] The present invention also provides a treatment process of an anaerobic ammonia oxidation reactor for treating high-ammonia nitrogen coal-to-liquid wastewater, comprising the following specific use steps:

[0065] Step 1: wastewater enters the interior of the reaction tank through the water inlet pipe, and the wastewater is detected by the PH detector. When the PH detector detects that the PH value of the waste liquid is not within the standard value between 8.0 and 8.4, the PH detector will send an electrical signal to the alarm, causing the alarm to sound an alarm. According to the detected PH value, the gear of the double-gear rotary extrusion mechanism is selected. When the difference between the measured PH value and the standard value is within the normal range, the height position of the double-gear rotary extrusion mechanism is adjusted by the lifting device, so that the positions of the first extrusion disk and the elastic liquid spraying mechanism are aligned with each other, and the first extrusion disk rotates and squeezes the elastic liquid spraying mechanism, so that the elastic liquid spraying mechanism can store the PH stored in the inner cavity of the liquid storage ring. The H regulator is extracted and then sprayed out to adjust the pH value of the wastewater. When the measured pH value is too far from the standard value, the height position of the double-speed rotary extrusion mechanism is adjusted by the lifting device so that the second extrusion disk and the elastic liquid spraying mechanism are aligned with each other. The second extrusion disk rotates and squeezes the elastic liquid spraying mechanism so that the elastic liquid spraying mechanism extracts the pH regulator stored in the inner cavity of the liquid storage ring and then sprays it out. At this time, the dosage of the pH regulator is increased to achieve double-speed adjustment of the pH value of the wastewater. At this time, under the two gears, the fixed guide disk and the rotating guide disk are both in a dislocated and blocked state, and the wastewater will flow back to the water inlet pipe through the reflux pipe, and the pH value in the wastewater is tested again by the pH detector;

[0066] Step 2: After the test meets the standards, adjust the two-speed rotary extrusion mechanism to the middle gear. At this time, the elastic spray mechanism is opposite to the position of the middle disk, and the guide holes on the fixed guide disk correspond to the guide holes on the rotating guide disk. The sealing slide blocks the return pipe. At this time, the wastewater with adjusted pH value is diverted upward through the guide holes to be discharged after being treated by the anaerobic ammonia oxidation reaction of the anaerobic ammonia-oxidizing bacteria attached to the filler, thereby realizing the wastewater denitrification treatment process.

[0067] Technical effects and advantages of the present invention:

[0068] The present invention utilizes a setting mode in which a pH adjusting device and a gear adjusting device are matched, and through the rotation of the gear adjusting device, the pH adjusting agent inside the pH adjusting device is conveniently squeezed out to neutralize the pH value in the wastewater, and the pH value is adjusted to the range of 8.0-8.4, so that the anaerobic ammonia-oxidizing bacteria can ensure a high activity, so as to accelerate the reaction rate of converting ammonia nitrogen and nitrite nitrogen into nitrogen gas at the same time, so as to improve the denitrification treatment efficiency of the wastewater, and make the denitrification treatment effect better;

[0069] The present invention utilizes a setting mode that a rotating screw rod and a slider cooperate with each other, a positioning block is connected to the top of the slider, and a positioning groove is provided at the bottom of the fixed guide plate, and the positioning groove facilitates the linear translation sliding of the limit positioning block, and the rotating screw rod is rotated to cooperate with the threaded interpenetration between the rotating screw rod and the slider, so that the rotation of the rotating screw rod can promote the horizontal sliding of the slider, so that the slider drives the horizontal linear sliding of the two interpenetrating sliding rods, and the sliding interpenetration between the interpenetrating sliding rod and the inner cavity of the inclined guide groove is cooperated with the inclined setting of the inclined guide groove, so that the direction of the force is adjusted, so that the sliding extrusion of the interpenetrating sliding rod can push the side plate to move up and down, so as to adjust the position of the connecting plate up and down, thereby facilitating the adjustment of the relative position between the double-speed rotary extrusion mechanism and the elastic liquid spraying mechanism;

[0070] The present invention utilizes a setting mode in which a fixed guide plate and a rotating guide plate are matched. When the pH value of the wastewater is within the range of 8.0-8.4, the interlaced slide bar is located in the middle position of the inner cavity of the inclined guide groove. At this time, the position of the intermediate plate is opposite to that of the elastic liquid spraying mechanism, and the guide hole on the fixed guide plate corresponds to the position of the guide hole on the rotating guide plate. The sealing slide plate blocks the return pipe. At this time, the wastewater with adjusted pH value flows upward through the guide hole. When the pH value of the wastewater is not within the range of 8.0-8.4, the rotation of the rotating screw rod drives the synchronous rotation of the gear, and the meshing between the gear and the arc-shaped rack is matched, so that the rotation of the gear can be used as a driving force. The arc-shaped rack rotates so that the arc-shaped rack drives the rotating guide plate to rotate synchronously. The rotating guide plate rotates relative to the fixed axis of the fixed guide plate. On the one hand, the guide holes on the fixed guide plate and the guide holes on the rotating guide plate are misaligned with each other, and the solid part of the rotating guide plate blocks the guide holes on the fixed guide plate. On the other hand, driven by the rotation of the rotating guide plate, the sealing slide rotates in the direction away from the reflux pipe. At this time, the sealing slide no longer blocks the inner cavity of the reflux pipe, so that the waste liquid at the bottom of the reaction tank body cavity can flow back to the water inlet pipe through the reflux pipe, and the real-time pH monitoring is performed again by the pH detector.

At this time, the position of the intermediate plate 611 is opposite to that of the elastic spray mechanism 52, and the guide hole 83 on the fixed guide plate 81 corresponds to the position of the guide hole 83 on the rotating guide plate 82. The sealing slide plate 84 The reflux pipe 21 is blocked, and the wastewater after the pH value is adjusted flows upward through the guide hole 83. When the pH value of the wastewater is not within the range of 8.0-8.4, the rotation of the rotating screw 71 drives the synchronous rotation of the gear 77, and the meshing between the gear 77 and the arc-shaped rack 86 makes the rotation of the gear 77 serve as a power to promote the rotation of the arc-shaped rack 86, so that the arc-shaped rack 86 drives the rotating guide plate 82 to rotate synchronously.

When the measured pH value is too far from the standard value, the height position of the double-speed rotary extrusion mechanism 61 is adjusted by the lifting device 7, so that the second extrusion disk 613 and the elastic liquid spraying mechanism 52 are aligned with each other. The second extrusion disk 613 rotates and squeezes the elastic liquid spraying mechanism 52, so that the elastic liquid spraying mechanism 52 extracts the pH regulator stored in the inner cavity of the liquid storage ring 51 and then sprays it out. At this time, the dosage of the pH regulator is increased to achieve double-speed adjustment of the pH value of the wastewater. At this time, under the two gears, the fixed guide disk 81 and the rotating guide disk 82 are both in a dislocated and blocked state, and the wastewater will flow back to the water inlet pipe 2 through the reflux pipe 21, and the pH value in the wastewater is tested again by the pH detector 3;
