Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, it relates to a device for rapidly reducing ammonia nitrogen in wastewater treatment. Background Technology

[0002] Wastewater treatment is a core component of environmental engineering, aiming to remove pollutants from wastewater through physical, chemical, and biological methods to meet discharge standards or reuse requirements. Water balance and pressure / flow monitoring play crucial roles in the design, operation, optimization, and management of wastewater treatment plants.

[0003] In wastewater treatment, reducing ammonia nitrogen (NH3-N) is the core step in the denitrification process and is crucial for preventing eutrophication of water bodies. In cases requiring emergency treatment, the breakpoint chlorination method is usually used. Chlorine gas is added to the wastewater in the treatment tank. The chlorine reacts with the ammonia nitrogen in the wastewater in a series of reactions. When the amount of chlorine added reaches the "breakpoint", the ammonia nitrogen is completely oxidized to nitrogen gas (N2), thus removing the ammonia nitrogen from the wastewater.

[0004] However, chlorine reacts with organic matter in water (such as humic acid and fulvic acid) to produce carcinogenic, teratogenic, and mutagenic disinfection byproducts such as trihalomethanes (THMs) and haloacetic acids (HAAs). The effluent may violate stricter water quality standards (such as limits on THMs), causing secondary pollution. Usually, a set of stirring racks is installed in the treatment tank, but the presence of four corners on the set of stirring racks may lead to insufficient mixing of water and chlorine, thus affecting the treatment effect. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a device for rapidly reducing ammonia nitrogen in wastewater treatment, in order to solve the technical problem mentioned in the background art that a set of stirring racks has four corners, which may lead to insufficient mixing of water and chlorine gas, thereby affecting the treatment effect.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A device for rapidly reducing ammonia nitrogen in wastewater treatment includes a flocculation tank with four sets of support legs on its outer side. An inlet pipe is located at the left end of the flocculation tank, and a water pump is located at the right end. A bend is installed at the input end of the water pump, connecting to the right end of the flocculation tank. A treatment tank is located at the output end of the water pump. Four support pillars are located at the bottom of the treatment tank. A motor is located at the top of the treatment tank, and a rotating shaft is located at the output end of the motor. The rotating shaft is rotatably installed inside the treatment tank. Multiple sets of paddle-type stirring blades are located on the upper part of the rotating shaft, and multiple sets of anchor-type stirring blades are located at the lower part of the rotating shaft. A drain pipe with a drain valve is located at the right end of the treatment tank. A material tank containing sodium hypochlorite solution is located at the top of the treatment tank.

[0007] The present invention is further configured such that a storage tank is provided at the top of the flocculation box, and a discharge pipe is provided at the bottom of the storage tank. The discharge pipe is connected to the top of the flocculation box and a metering valve is provided on the discharge pipe. A motor is provided at the left end of the flocculation box, and a stirring shaft is provided through the output end of the motor through the flocculation box. The stirring shaft is rotatably installed inside the flocculation box and is provided with multiple sets of stirring blades. Wastewater is introduced into the flocculation box through the inlet pipe, and then the metering valve is opened, and the flocculant in the storage tank is meteredly introduced into the flocculation box through the discharge pipe. After starting the first stage, motor two is turned on, which drives the stirring shaft to rotate. The stirring shaft then drives multiple sets of stirring blades to mix the water and flocculant, thereby flocculating the organic matter in the water. The wastewater is then allowed to settle, and the flocculated impurities settle at the bottom of the flocculation tank. By turning on the water pump, the flocculated wastewater in the flocculation tank is introduced into the treatment tank through a bend in the pipe and the pump. This further flocculation significantly reduces the organic matter content entering the "breakpoint chlorination" stage, thus fundamentally reducing the generation of DBPs such as THMs and HAAs. This is the most fundamental and effective strategy for controlling DBPs.

[0008] This invention is further configured such that a guide pipe is provided on the lower left side of the material tank, a second metering valve is provided on the guide pipe, a rotary joint is provided on the upper part of the rotating shaft, the rotary joint is connected to the guide pipe, a chamber is provided on the upper part of the rotating shaft, the rotary joint is connected to the chamber, a water guiding cavity is provided in each of the multiple sets of paddle agitators, and the multiple sets of water guiding cavities are connected to the chamber, and multiple sets of nozzles are provided on each set of paddle agitators. By opening the second metering valve, sodium hypochlorite in the material tank is introduced into the multiple sets of paddle agitators through the guide pipe, rotary joint and rotating shaft and discharged by the multiple sets of nozzles. Sodium hypochlorite reacts with ammonia nitrogen in the water. This not only allows sodium hypochlorite solution to replace chlorine gas, avoiding the risks of chlorine leakage, storage and operation, and greatly improving on-site safety, but also allows sodium hypochlorite to be discharged under the agitation of multiple sets of paddle agitators, so that sodium hypochlorite can fully contact and react with sewage.

[0009] The present invention is further configured such that an activated carbon block is provided at the outlet end of the drain pipe, the activated carbon block has a chamber, the chamber contains activated carbon material, and the left and right ends of the activated carbon block are connected to multiple sets of filter holes. Even after optimization, there may still be trace amounts of residual chlorine and DBPs after inflection point chlorination. The activated carbon material in the activated carbon block adsorbs the residual chlorine and DBPs in the discharged water, which can effectively remove residual chlorine and adsorb residual DBPs, ensuring that the final effluent meets stricter water quality standards and preventing secondary pollution.

[0010] The present invention is further configured such that a motor is provided at the top of the material barrel, and an agitator shaft is provided through the output end of the motor through the top of the material barrel. The agitator shaft is rotatably installed inside the material barrel, and multiple sets of agitator blades are provided on the agitator shaft. When the motor is turned on, the motor drives the agitator shaft to rotate, and the agitator shaft drives the multiple sets of agitator blades to rotate. The multiple sets of agitator blades stir the sodium hypochlorite solution in the material barrel to ensure the concentration of the sodium hypochlorite solution.

[0011] The present invention is further configured such that a sludge hopper is connected to the bottom end of the flocculation box, and a control valve is provided on the sludge hopper. By setting the sludge hopper and the control valve, it is convenient to discharge the flocculated impurities from the sludge hopper by opening the control valve.

[0012] The present invention is further configured such that a first flange is provided at the right end of the drain pipe, and a second flange is provided at both the left and right ends of the activated carbon block. Multiple sets of through holes are symmetrically connected on the first flange and the two sets of second flanges. Bolts are movably installed in the multiple sets of through holes of the second flange on the left side. Multiple sets of nuts are provided through the through holes of the second flange on the right side and the first flange respectively. When it is necessary to replace the activated carbon block, the multiple sets of nuts are unscrewed, and the multiple sets of bolts are removed from the two sets of second flanges, thereby removing the activated carbon block from the drain pipe for replacement, which facilitates the disassembly and replacement of the activated carbon block.

[0013] Beneficial effects Compared with the prior art, this utility model provides a device for rapidly reducing ammonia nitrogen in wastewater treatment, which has the following beneficial effects: 1. A water pump is installed at the right end of the flocculation tank. The bend pipe is connected to the right end of the flocculation tank. A motor is installed at the top of the treatment tank. The rotating shaft is rotatably installed inside the treatment tank. Multiple sets of paddle-type stirring blades are installed on the upper part of the rotating shaft, and multiple sets of anchor-type stirring blades are installed on the lower part of the rotating shaft. A material tank is installed at the top of the treatment tank. Sodium hypochlorite solution is placed in the material tank. Wastewater is introduced into the water pump through the inlet pipe for flocculation. Then, the water pump is turned on, and the flocculated wastewater is introduced into the treatment tank through the bend pipe and the water pump. Then, the sodium hypochlorite solution in the material tank is introduced into the treatment tank. The motor is turned on, and the motor drives the rotating shaft to rotate. The multiple sets of paddle-type stirring blades and multiple sets of anchor-type stirring blades on the rotating shaft agitate the water, so that the water and sodium hypochlorite react fully to reduce ammonia nitrogen. This can greatly improve the mixing effect at the bottom and four corners of the tank and improve its treatment effect.

[0014] 2. A discharge pipe is installed at the bottom of the storage tank, and a metering valve is installed on the discharge pipe. A motor is installed at the left end of the flocculation tank, and a stirring shaft is installed through the output end of the motor through the flocculation tank. The stirring shaft is equipped with multiple sets of stirring blades. Wastewater is introduced into the flocculation tank through the inlet pipe. Then, the metering valve is opened, and the flocculant in the storage tank is metered into the flocculation tank through the discharge pipe. Then, the motor is turned on, and the motor drives the stirring shaft to rotate. The stirring shaft drives the multiple sets of stirring blades to stir and mix the water and flocculant, thereby flocculating the organic matter in the water. Then, the wastewater is allowed to settle. The flocculated impurities settle at the bottom of the flocculation tank. By turning on the water pump, the flocculated wastewater in the flocculation tank is introduced into the treatment tank through the bend pipe and the water pump. This allows for further flocculation of the wastewater, which significantly reduces the organic matter content entering the "breakpoint chlorination" stage, thereby fundamentally reducing the generation of DBPs such as THMs and HAAs. This is the most fundamental and effective strategy for controlling DBPs.

[0015] 3. A feed pipe is provided on the lower left side of the feed tank, and a second metering valve is provided on the feed pipe. A rotary joint is provided on the upper part of the rotating shaft, and the rotary joint is connected to the feed pipe.

Each set of paddle agitators is provided with a water guiding chamber, and each set of water guiding chambers is connected to the chamber. Each set of paddle agitators is provided with multiple sets of nozzles. By opening the second metering valve, sodium hypochlorite in the feed tank is introduced into the multiple sets of paddle agitators through the feed pipe, rotary joint, and rotating shaft and discharged by the multiple sets of nozzles. Sodium hypochlorite reacts with ammonia nitrogen in the water. This not only allows sodium hypochlorite solution to replace chlorine gas, avoiding the risks of chlorine leakage, storage, and operation, and greatly improving on-site safety, but also allows sodium hypochlorite to be discharged under the agitation of multiple sets of paddle agitators, ensuring that sodium hypochlorite fully contacts and reacts with the wastewater.

[0020] Please see Figure 1-6A device for rapidly reducing ammonia nitrogen in wastewater treatment includes a flocculation tank 1, four sets of support legs 2 on the outside of the flocculation tank 1, an inlet pipe 3 at the left end of the flocculation tank 1, a water pump 4 at the right end of the flocculation tank 1, a bend pipe 5 at the input end of the water pump 4 connected to the right end of the flocculation tank 1, a treatment tank 6 at the output end of the water pump 4, four sets of support columns 7 at the bottom of the treatment tank 6, a motor 8 at the top of the treatment tank 6, a rotating shaft 9 at the output end of the motor 8, the rotating shaft 9 being rotatably installed inside the treatment tank 6, multiple sets of paddle-type stirring blades 10 at the upper part of the rotating shaft 9, multiple sets of anchor-type stirring blades 11 at the lower part of the rotating shaft 9, a drain pipe 12 at the right end of the treatment tank 6, a drain valve 13 on the drain pipe 12, and a material tank 14 at the top of the treatment tank 6 containing sodium hypochlorite solution. In this embodiment, wastewater is introduced into the water pump 4 through the inlet pipe 3 for flocculation. Then, the water pump 4 is turned on, and the flocculated wastewater is introduced into the treatment tank 6 through the bend pipe 5 and the water pump 4. Then, the sodium hypochlorite solution in the material tank 14 is introduced into the treatment tank 6. The motor 8 is turned on, and the motor 8 drives the rotating shaft 9 to rotate. The multiple sets of paddle-type stirring blades 10 and multiple sets of anchor-type stirring blades 11 on the rotating shaft 9 stir the water, so that the water and sodium hypochlorite can fully react to reduce ammonia nitrogen. The multiple sets of paddle-type stirring blades 10 have the characteristics of high speed, high shear force and large circulation flow. They can quickly disperse and initially mix the newly added sodium hypochlorite solution or flocculant, and promote the water flow to form a strong circulation in the upper part of the tank. The multiple sets of anchor-type stirring blades 11 can rotate closely against the inner wall and bottom of the treatment tank 6, effectively removing sediment, preventing sludge accumulation, and "scraping" up the water at the bottom to exchange with the water flow at the top, which greatly improves the mixing effect at the bottom and four corners of the tank and improves its treatment effect.

[0021] Please see Figure 1 and Figure 3 As one embodiment of the flocculation box 1, the flocculation box 1 of this utility model is provided with a storage box 15 at the top and a discharge pipe 16 at the bottom of the storage box 15. The discharge pipe 16 is connected to the top of the flocculation box 1 and a metering valve 17 is provided on the discharge pipe 16. A motor 18 is provided at the left end of the flocculation box 1. A stirring shaft 19 is provided through the output end of the motor 18 and is rotatably installed inside the flocculation box 1. Multiple sets of stirring blades 20 are provided on the stirring shaft 19. Specifically, wastewater is introduced into the flocculation tank 1 through the inlet pipe 3. Then, the metering valve 17 is opened, and the flocculant in the storage tank 15 is metered into the flocculation tank 1 through the discharge pipe 16. Next, the motor 18 is turned on, which drives the stirring shaft 19 to rotate. The stirring shaft 19 drives multiple sets of stirring blades 20 to mix the water and flocculant, thereby flocculating the organic matter in the water. The wastewater is then allowed to settle, and the flocculated impurities settle at the bottom of the flocculation tank 1. By turning on the water pump 4, the flocculated wastewater in the flocculation tank 1 is introduced into the treatment tank 6 through the bend pipe 5 and the water pump 4. This process significantly reduces the organic matter content entering the "breakpoint chlorination" stage, thereby fundamentally reducing the generation of DBPs such as THMs and HAAs. This is the most fundamental and effective strategy for controlling DBPs.

[0022] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As one embodiment of the material barrel 14, the material barrel 14 in this utility model is provided with a guide pipe 21 on the lower left side, and a metering valve 22 is provided on the guide pipe 21. A rotary joint 23 is provided on the upper part of the rotating shaft 9, and the rotary joint 23 is connected to the guide pipe 21. A chamber is provided on the upper part of the rotating shaft 9, and the rotary joint 23 is connected to the chamber. A water guiding chamber is provided in each of the multiple sets of paddle stirring blades 10, and the multiple sets of water guiding chambers are connected to the chamber. A number of nozzles 24 are provided on each set of paddle stirring blades 10. A motor 26 is provided at the top of the material barrel 14. An agitator 27 is provided through the output end of the motor 26 and is rotatably installed inside the material barrel 14. A number of agitator blades 28 are provided on the agitator 27. Specifically, by opening the metering valve 22, sodium hypochlorite in the feed tank 14 is introduced into multiple sets of paddle agitators 10 through the feed pipe 21, rotary joint 23, and rotating shaft 9, and then discharged by multiple sets of nozzles 24. The sodium hypochlorite reacts with the ammonia nitrogen in the water. This not only allows the sodium hypochlorite solution to replace chlorine gas, avoiding the risks of leakage, storage, and operation of highly toxic and high-pressure gases, thus greatly improving on-site safety, but also allows the sodium hypochlorite to be discharged under the agitation of multiple sets of paddle agitators 10, ensuring that the sodium hypochlorite fully contacts and reacts with the wastewater. By opening the motor 26, the motor 26 drives the stirring shaft 27 to rotate, which in turn drives multiple sets of agitators 28 to rotate. The multiple sets of agitators 28 then stir the sodium hypochlorite solution in the feed tank 14, ensuring the concentration of the sodium hypochlorite solution.

[0023] Please refer to Figure 2 , Figure 4 and Figure 6As a further embodiment of the drain pipe 12: an activated carbon block 25 is provided at the output end of the drain pipe 12, a chamber is provided inside the activated carbon block 25, and activated carbon material is provided in the chamber. Multiple sets of filter holes are provided at both the left and right ends of the activated carbon block 25. A first flange 31 is provided at the right end of the drain pipe 12, and a second flange 32 is provided at both the left and right ends of the activated carbon block 25. Multiple sets of through holes are symmetrically provided on the first flange 31 and the two sets of second flanges 32. Bolts 33 are movably provided in the multiple sets of through holes of the second flange 32 on the left side. Multiple sets of nuts 34 are provided through the through holes of the second flange 32 on the right side and the first flange 31 respectively. Specifically, even after optimization, trace amounts of residual chlorine and DBPs may still remain after inflection point chlorination. The activated carbon material inside the activated carbon block 25 adsorbs the residual chlorine and DBPs in the discharged water, effectively removing residual chlorine and adsorbing residual DBPs, ensuring that the final effluent meets stricter water quality standards and preventing secondary pollution. When the activated carbon block 25 needs to be replaced, unscrew multiple sets of nuts 34 and remove multiple sets of bolts 33 from the two sets of second flanges 32, thereby removing the activated carbon block 25 from the drain pipe 12 for replacement, making it easy to disassemble and replace the activated carbon block 25.

[0024] The present invention has a sludge discharge hopper 29 connected to the bottom end of the flocculation box 1, and a control valve 30 is provided on the sludge discharge hopper 29. By setting the sludge discharge hopper 29 and the control valve 30, it is convenient to discharge the flocculated impurities from the sludge discharge hopper 29 by opening the control valve 30.

[0025] Both the storage bin 15 and the material bucket 14 are equipped with water inlet components at their tops, and the processing bucket 6 may be equipped with an air purification device.

[0026] In summary, when using the overall equipment: Wastewater is introduced into the flocculation tank 1 through the inlet pipe 3. Then, the metering valve 17 is opened, and the flocculant in the storage tank 15 is metered into the flocculation tank 1 through the discharge pipe 16. Then, the motor 18 is turned on, which drives the stirring shaft 19 to rotate. The stirring shaft 19 drives multiple sets of stirring blades 20 to stir and mix the water and flocculant, thereby flocculating the organic matter in the water. Then, the wastewater is allowed to settle and the flocculated impurities settle at the bottom of the flocculation tank 1. By turning on the water pump 4, the flocculated wastewater in the flocculation tank 1 is introduced into the treatment tank 6 through the bend pipe 5 and the water pump 4.

[0027] After the wastewater is introduced into the treatment tank 6, the metering valve 22 is opened. Sodium hypochlorite in the material tank 14 is introduced into multiple sets of paddle agitators 10 through the feed pipe 21, rotary joint 23 and rotating shaft 9 and discharged by multiple sets of nozzles 24. At the same time, motor 8 is turned on, which drives the rotating shaft 9 to rotate. The multiple sets of paddle agitators 10 and multiple sets of anchor agitators 11 on the rotating shaft 9 agitate the water. The sodium hypochlorite sprayed by the multiple sets of nozzles 24 fully contacts and reacts with the water to reduce ammonia nitrogen.

[0028] When the water after ammonia nitrogen removal is discharged, the drain valve 13 is opened, and the water is discharged after being adsorbed by the activated carbon block 25 in the drain pipe 12 to remove residual chlorine and DBPs.
