Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an efficient DBIO process and treatment equipment. Background Art

[0002] As an important part of environmental governance, the sewage treatment industry also shoulders the important mission of reducing carbon emissions. It is of great significance to promote the carbon transformation of the sewage treatment industry. First of all, reducing carbon emissions in the sewage treatment process is an urgent task. Sewage treatment plants will produce a large amount of carbon emissions during operation, including carbon emissions from energy consumption and carbon emissions from chemical agents. Secondly, low-carbon transformation is conducive to improving the sustainable development capabilities of the sewage treatment industry. Finally, low-carbon transformation can also improve urban ecological environment governance and improve the quality of life of residents. The existing sewage contains a large amount of ammonia nitrogen substances that need to be treated. At present, when purifying ammonia nitrogen substances in sewage, A0 technology is usually used to remove ammonia nitrogen substances in sewage.

[0003] In the existing traditional AO process sewage treatment plant, the sewage flows by gravity into the anoxic tank (A tank) and the aerobic tank (O tank) in sequence. When the tank body is a civil structure, the height is generally 4 to 6 meters; when it is an integrated device, the height is only 3 to 3.5 meters. If fillers are added into the pool, the filler dosage generally does not exceed 30%, and the residence time is generally 9 to 22 hours, resulting in a low sewage treatment effect. At the same time, during the anoxic and aerobic stages, the bacteria in the fillers cannot be fully in contact with the sewage, resulting in the inability of the biological bacteria in the fillers to fully react with the sewage, resulting in a poor denitrification effect on the ammonia nitrogen in the sewage. The present invention mainly considers the structure of the integrated biochemical treatment equipment and its process parameters, and adopts a deep bed doubling efficient biochemical modular technology equipment, the full English name is: Deep bed doubling efficient biochemical modular technology equipment (abbreviated as DBIO in this application). The DBIO system is a modified biochemical pool with a vertical layered structure. Through the different effects of bacteria in different layers, on the basis of internal circulation, synchronous nitrification and denitrification are achieved to remove ammonia nitrogen and total nitrogen pollutants in sewage.

[0014] An efficient DBIO process includes the following steps:

[0015] Step 1: Fill the anoxic reaction filler and the aerobic reaction filler in the anoxic filler frame and the aerobic filler frame, with the filler filling ratio being ≥70%, and at the same time continue to connect the aerobic aeration main pipe with the external aerator;

[0016] Step 2: Connect the sewage discharge pipe to the water inlet pipe on the tank body, and then the water inlet pipe will pass the sewage to the bottom of the tank body through the water inlet branch pipe and the water distributor, and start the aerator at the same time. Then the sewage will pass through the fillers in the anoxic filler frame and the aerobic filler frame from bottom to top for biochemical reaction purification, and the purified water will be discharged through the water outlet pipe at the top of the tank body;

[0017] Step 3: Every 15 days, remove the mud from the fillers in the anoxic filler frame and the aerobic filler frame, and replace the internal fillers.

[0018] Beneficial effects of the present invention:

[0019] (1) An anaerobic filler layer and an aerobic filler layer are arranged in the tank body from bottom to top, and then an anaerobic biological filler and aerobic biological filler are filled in the anaerobic filler frame and the aerobic filler frame respectively. Then, sewage is supplied to the bottom of the sewage tank body, and then the sewage flows upward from the bottom. Then, the bacteria in the fillers in the anaerobic filler layer and the aerobic filler layer respectively react biochemically with the total nitrogen and ammonia nitrogen substances in the sewage. At the same time, through the cooperation of the disturbance mechanism, the total nitrogen and ammonia nitrogen substances in the sewage are effectively removed.

[0020] (2) The anoxic biochemical reaction and the aerobic biochemical reaction are combined in a tank to purify the sewage, so that the equipment occupies a small area and saves space. At the same time, the high filling ratio filler can intercept and filter the sludge and other suspended matter in the sewage, so that the effluent of the equipment does not contain sludge and other suspended matter. There is no need to treat the treated sewage, which reduces the cost of sludge disposal. At the same time, the simultaneous nitrification and denitrification process is adopted, and the filler of the filler frame is used to make the filler filling rate in the filler frame larger, which reduces the reaction time between the sewage and the filler, which is much shorter than the retention time of the traditional biochemical pool, thereby improving the treatment efficiency of the sewage.

[0021] (3) The threaded rod in the installation box is driven by the driving mechanism to rotate forward and backward, and the threaded rod drives the transmission plate to move up and down reciprocatingly. At the same time, the installation box on the transmission plate cooperates with the transmission mechanism to drive the spring and the flexible brush to move up and down and rotate forward and backward in the stuffing box to disturb the stuffing in the stuffing box, so that the biological bacteria in the stuffing in the stuffing box and the sewage can be contacted and reacted, thereby further improving the sewage treatment effect. At the same time, during the disturbance process, the elastic expansion and contraction of the spring changes the shape of the spring, thereby realizing irregular disturbance of the spring, further improving the disturbance effect on the stuffing, and prompting the sewage and the stuffing to fully react. At the same time, when encountering hard stuffing, the spring can be compressed, so that the installation box can continue to drive the first transmission shaft to move, thereby preventing the occurrence of jamming during the disturbance process, and further improving the stability of the equipment.

[0022] (4) The transmission tube rotates forward and backward, and the transmission tube drives the third bevel gear in the second transmission box to rotate. The third bevel gear drives the fourth bevel gear to rotate. The fourth bevel gear drives the screw rod to rotate forward and backward, so that the screw rod drives the filler in the filler frame to move back and forth, so that the filler in the filler box is evenly distributed in the filler box, thereby promoting the bacteria in the filler in the filler frame to be evenly distributed, further increasing the contact area between the bacteria and the sewage, and improving the biochemical reaction effect of the bacteria on the sewage.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See also Figure 1-Figure 9 As shown, the present invention is an efficient DBIO process and treatment equipment, comprising a tank body 1, an anoxic packing frame 2 is fixedly connected in the tank body 1, an aerobic packing frame 3 fixedly connected to the tank body 1 is arranged above the anoxic packing frame 2, a filter interception net 4 is fixedly connected to the top and bottom of the anoxic packing frame 2 and the aerobic packing frame 3 by bolts, and a disturbance mechanism is arranged in the anoxic packing frame 2, and the disturbance mechanism is used to disturb the microorganisms in the anoxic packing frame 2 to increase the reaction between the microorganisms and the sewage;

[0037] A water inlet main pipe 5 is fixedly connected to the bottom of the tank body 1, a plurality of water inlet branch pipes 6 are fixedly connected to the outer surface of the water inlet main pipe 5, a plurality of water distributors 7 are fixedly connected to the water inlet branch pipe 6, an aerobic aeration main pipe 8 fixedly connected to the tank body 1 is fixedly connected between the anoxic filler frame 2 and the aerobic filler frame 3, a plurality of aerobic aeration branch pipes 9 are fixedly connected to the outer surface of the aerobic aeration main pipe 8, and an aeration head 10 is fixedly connected to the aerobic aeration branch pipe 9.

[0038] Biomass carrier fillers are installed on the filter interception nets 4 at the top and bottom of the anoxic filler frame 2 and the aerobic filler frame 3, and then anoxic biological fillers and aerobic biological fillers are filled in the anoxic filler frame 2 and the aerobic filler frame 3 respectively, and the filling ratio of the fillers is ≥70%. Then, the sewage is evenly introduced into the bottom of the tank body 1 through the water distributor 7 on the water inlet branch pipe 6 through the water inlet main pipe 5, and then the sewage flows upward into the anoxic filler frame 2, and then the anoxic biological filler in the anoxic filler frame 2 performs a biochemical reaction on the sewage, and then the sewage The wastewater enters the aerobic filler frame 3 through the filter interception net 4 to undergo biological reaction with the aerobic biological filler. Meanwhile, a large amount of air is blown into the aerobic biological filler in the aerobic filler frame 3 through the aerobic aeration main pipe 8, the aerobic aeration branch pipe 9 and the aeration head 10, so that the aerobic filler is fully supplied with oxygen. Meanwhile, during the anoxic and aerobic biochemical reaction process, the filler is disturbed by the disturbance mechanism to promote the fluidity of the biological bacteria in the filler, so that the sewage is fully in contact with the biological bacteria, thereby further improving the treatment effect of ammonia nitrogen substances in the sewage. At the same time, the anoxic biochemical reaction and the aerobic biochemical reaction are combined in a tank body 1 to purify the sewage, so that the equipment occupies a small area and saves space. At the same time, the biological filler is filled in the filling frame, and then intercepted by the filtering interception net 4, so that after the sewage is treated, the sewage does not contain sludge in the filler, and there is no need to treat the treated sewage with sludge, thereby reducing the disposal cost of the sludge. At the same time, the simultaneous nitrification and denitrification process is adopted, and the filler of the filler frame is used to make the filler filling rate in the filler frame larger, thereby reducing the reaction time between the sewage and the filler, which is much shorter than the retention time of the traditional biochemical pool, thereby improving the treatment efficiency of the sewage.

[0039] At the same time, anoxic biological fillers and aerobic biological fillers are filled in the anoxic filler frame 2 and the aerobic filler frame 3, and the filling ratio of the fillers is ≥70%, which is different from the existing specification "Outdoor Drainage Design Standard" which stipulates that "the filling ratio of suspended fillers can be 20% to 60%, and is generally required to be less than or equal to 67%";

[0040] High filling ratio fillers provide more carriers for the growth of microorganisms. When the influent COD≤180mg / L; BOD≤100mg / L; ammonia nitrogen≤20; TN≤25mg / L; system residence time≤4h, the sewage treatment effluent can reach the Class A emission standard in the "Pollutant Discharge Standard for Urban Sewage Treatment Plants", that is, COD≤50mg / L; BOD≤10mg / L; ammonia nitrogen≤5; TN≤15mg / L; the biochemical residence time is much shorter than the traditional sewage treatment process (the traditional AO treatment process in the "Outdoor Drainage Design Standard" has a residence time of 9 to 22h);

[0041] At the same time, according to the current on-site test results, when the average values ​​of influent COD and ammonia nitrogen are 173 mg / L and 14 mg / L respectively; the maximum removal rates of system COD and ammonia nitrogen can reach 95.2% and 97.92% respectively; the sludge discharge cycle of the DBIO system is about 15 days, which is shorter than the sludge discharge cycle of the current sewage treatment plant process system, and there is no need to discharge sludge every day.
