Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to sewage treatment equipment with nitrification reaction and a treatment method thereof. Background Art

[0002] In the process of industrial production, especially in the chemical, pharmaceutical, food processing and other industries, sewage often contains high concentrations of ammonia nitrogen. Direct discharge will seriously pollute the water body and affect the ecological environment. Nitrification reaction is an important process in sewage biological treatment. It mainly consists of two steps: first, under the action of nitrite bacteria (such as Nitrosomonas), ammonia (NH3) is oxidized into nitrite (NO2⁻) and releases energy; then, under the action of nitrate bacteria (such as Nitrobacter, Nitrococcus, etc.), nitrite is further oxidized into nitrate (NO3⁻), and energy is released again. After nitrification reaction, ammonia nitrogen and nitrite nitrogen in sewage are effectively removed or converted, achieving the effect of reducing toxicity, improving biodegradability and providing conditions for subsequent denitrification treatment. However, traditional sewage treatment methods have problems such as low treatment efficiency, high energy consumption and high cost when treating such sewage.

[0003] For example, the Chinese invention patent CN202410077942.3 discloses “a sewage treatment device with nitrification reaction and a treatment method thereof”, and its specification discloses that when the existing sewage treatment equipment is in use, the sludge in the sewage is easily accumulated, resulting in reduced treatment efficiency, and after the sewage undergoes nitrification or denitrification reaction in the aerobic zone or anaerobic zone, it is necessary to discharge the sewage into the anaerobic zone or aerobic zone through a water pump for alternating treatment of denitrification and nitrification reactions, and the pumping process requires a lot of waiting time, resulting in low treatment efficiency; the above patents can prove the defects of the prior art.

[0041] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1 and Figure 7 A sewage treatment equipment with nitrification reaction includes a containing component 1, a first driving component 2 is provided on one side of the containing component 1, a material mixing component 3 is provided inside the containing component 1, a second driving component 4 and an aeration component 5 are provided on the rear side of the containing component 1, the aeration component 5 is located below the second driving component 4, the second driving component 4 is connected to the aeration component 5, and drives the aeration component 5 to move longitudinally, and the first driving component 2 is connected to the material mixing component 3 and the second driving component 4, and drives the material mixing component 3 and the second driving component 4 to move synchronously.

[0043] When the first driving component 2 is in operation, it drives the material mixing component 3 and the second driving component 4 to operate at the same time. The material mixing component 3 stirs and mixes the sewage and the mixed liquid. The mixing process ensures that the pollutants, microorganisms and nutrients in the sewage are evenly distributed, thereby improving the reaction efficiency. When the second driving component 4 is in operation, it drives the aeration component 5 to operate and perform aeration work. The aeration process provides sufficient oxygen for the microorganisms, supports their aerobic respiration and metabolic activities, and helps to degrade pollutants.

[0044] Further, such as Figure 1 As shown, the containing assembly 1 includes a container 11 and an input pipe 13, a reflux pipe 14, an output pipe 15, and a mixed liquid pipe 110 fixedly arranged at the bottom of one side of the container 11, and also includes a top cover 12 arranged at the top of the container 11 and an exhaust pipe 16 fixedly arranged at the top of the top cover 12.

[0045] Sewage can be input into the interior of the container 11 through the input pipe 13, the mixed liquid can be input into the interior of the container 11 through the mixed liquid pipe 110, the treated water can be discharged into the sedimentation tank through the output pipe 15, and the sludge in the sedimentation tank can be returned to the interior of the container 11 through the return pipe 14. During the aeration operation, the air can finally be discharged through the exhaust pipe 16.

[0046] Further, such as Figure 1 , Figure 2 and Figure 7 As shown, the containing assembly 1 also includes a T-shaped slider 17 fixed to the bottom of the top cover 12, and a guide groove 19 opened at the top of the container 11, the T-shaped slider 17 is slidably set in the guide groove 19, a mounting groove is opened at the bottom of the top cover 12, and a cylinder 18 is rotatably set in the mounting groove.

[0047] The T-shaped slider 17 can slide along the length direction of the guide slot 19, so that the top cover 12 can be slid open or closed. At the same time, the guide slot 19 also limits the T-shaped slider 17 to prevent the top cover 12 from sliding off. When the top cover 12 moves, the cylinder 18 passively rotates to reduce the friction of the top cover 12 when moving, thereby greatly improving the smoothness of the top cover 12 when moving.

[0048] Further, such as Figure 1 and Figure 4 As shown, the material mixing assembly 3 includes a rotating shaft 31 rotatably arranged inside the container 11 and a stirring roller body 32 fixedly sleeved on the rotating shaft 31 .

[0049] When the rotating shaft 31 rotates, it can drive the stirring roller 32 to rotate synchronously. The blades of the stirring roller 32 continuously stir the inside of the container 11 to improve the mixing efficiency of the sewage and the mixed liquid. The mixing process ensures that the pollutants, microorganisms and nutrients in the sewage are evenly distributed in the container 11, thereby improving the reaction efficiency.

[0050] Further, such as Figure 1 , Figure 5 and Figure 6 As shown, the second driving assembly 4 includes two support members 42 fixedly arranged on the rear side of the container 11 and a reciprocating screw rod 41 rotatably arranged between the two support members 42, and also includes a nut 43 sleeved on the reciprocating screw rod 41 and a driving block 44 fixedly arranged at the bottom of the nut 43, and the front side of the nut 43 is in contact with the rear side of the container 11.

[0051] Since the front side of the nut 43 fits with the rear side of the container 11, the nut 43 is restricted and cannot rotate along with the reciprocating screw 41. When the reciprocating screw 41 rotates, the nut 43 reciprocates in a straight line along the axial direction of the reciprocating screw 41 and can drive the drive block 44 to move synchronously.

[0052] Further, such as Figure 1 , Figure 4 and Figure 5 As shown, the first drive assembly 2 includes a motor 21 fixedly arranged on one side of the container 11 and a third transmission wheel fixedly arranged on the output shaft of the motor 21, and also includes a transmission belt 23 arranged on the third transmission wheel. A second transmission wheel 24 is arranged below the third transmission wheel. One end of the rotating shaft 31 passes through the container 11 and is fixedly connected to the second transmission wheel 24. One end of the reciprocating screw rod 41 is fixedly provided with the first transmission wheel 22. The third transmission wheel is transmission-connected to the first transmission wheel 22 and the second transmission wheel 24 through the transmission belt 23. The input pipe 13, the return pipe 14 and the output pipe 15 are all located below the second transmission wheel 24.

[0053] When the motor 21 is running, the torque is transmitted through the output shaft to drive the third transmission wheel to rotate. The third transmission wheel drives the first transmission wheel 22 and the second transmission wheel 24 to rotate through the transmission belt 23. The first transmission wheel 22 can drive the reciprocating screw rod 41 to rotate, and the second transmission wheel 24 can drive the rotating shaft 31 to rotate.

[0054] Further, such as Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the aeration assembly 5 includes an air cylinder 51 fixedly arranged on the rear side of the container 11, the air cylinder 51 is located below the driving block 44, a piston 54 is provided inside the air cylinder 51, a driving rod 52 is fixedly arranged on the top of the piston 54, a hemisphere 53 is provided above the air cylinder 51, the top of the driving rod 52 passes through the air cylinder 51 and is fixedly connected to the bottom of the hemisphere 53, a coil spring 55 is provided below the piston 54, an air inlet pipe 56 is fixedly arranged on the outer wall of the air cylinder 51, a first one-way valve 57 is provided on the air inlet pipe 56, an air outlet pipe 58 is fixedly arranged on the bottom of the air cylinder 51, an aeration pipe 59 is fixedly arranged on the inner wall of the rear side of the container 11, a second one-way valve 510 is provided on the aeration pipe 59, a spring 511 is fixedly arranged on the aeration pipe 59, and an end of the air outlet pipe 58 passes through the container 11 and is fixedly connected to the rear end of the aeration pipe 59.

[0055] The two sides of the driving block 44 are both inclined surfaces. When the driving block 44 follows the linear reciprocating motion of the nut 43, it will come into contact with the hemisphere 53. Each contact will cause the hemisphere 53 to move downward. When the hemisphere 53 moves downward, it pushes the driving rod 52 and the piston 54 downward, and the coil spring 55 is forced to shrink. Therefore, when the driving block 44 is separated from the hemisphere 53, the coil spring 55 automatically rebounds and pushes the piston 54, the driving rod 52, and the hemisphere 53 to move upward and reset, so that the piston 54 can realize longitudinal reciprocating motion. When the piston 54 moves upward, a negative pressure environment is formed in the internal working chamber of the air compressor 51, and the air in the external environment enters the working chamber through the air inlet pipe 56, while the sewage and mixed liquid inside the container 11 are restricted by the second one-way valve 510. When the piston 54 moves downward, a high-pressure environment is formed in the internal working chamber of the air compressor 51, forcing the air to enter the container 11 through the air outlet pipe 58 and the aeration pipe 59. During this process, the air is restricted by the first one-way valve 57 and cannot be discharged through the air inlet pipe 56. The piston 54 reciprocates longitudinally and can continuously input external air into the container 11 for aeration. When the stirring roller body 32 rotates with the rotating shaft 31, the blades of the stirring roller body 32 collide with the spring pieces 511 to generate vibration. On the one hand, the mixing efficiency of the sewage and the mixed liquid can be improved through vibration. On the other hand, the air bubbles entering the container 11 through the aeration pipe 59 can be dispersed into many small bubbles, thereby increasing the oxygen diffusion range and improving the overall work efficiency.

[0056] Embodiment 2: A sewage treatment method with nitrification reaction comprises the following steps:

[0057] S1. Sewage input: The sewage to be treated is introduced into the container 11 of the sewage treatment equipment through the input pipe 13;

[0058] S2, circulating mixed liquid input: the mixed liquid is introduced into the container 11 of the sewage treatment equipment through the mixed liquid pipeline 110;

[0059] S3, mixing and aeration: in the container 11, the sewage and the mixed liquid are fully mixed through the material mixing component 3, and sufficient oxygen is input through the aeration component 5 to maintain the dissolved oxygen concentration required by the nitrifying bacteria;

[0060] S4, nitrification reaction: Under suitable temperature, pH value and dissolved oxygen concentration conditions, ammonia nitrogen in sewage is oxidized into nitrite and nitrate by nitrifying bacteria, thus achieving the removal of ammonia nitrogen;

[0061] S5, solid-liquid separation: After the nitrification reaction is completed, the sludge enters the sedimentation tank through the output pipe 15 for solid-liquid separation, wherein the sludge part returns to the container 11 through the reflux pipe 14 to maintain the activity and quantity of nitrifying bacteria in the container 11, and the supernatant is discharged as treated sewage;

[0062] S6. Monitoring and adjustment: During the entire treatment process, water quality indicators and equipment operating parameters are monitored regularly, and treatment conditions are adjusted and optimized in a timely manner based on monitoring results to ensure that the effluent quality is stable and meets standards.

[0063] Under suitable environmental conditions, nitrifying bacteria efficiently convert ammonia nitrogen in sewage into nitrite and nitrate, effectively removing ammonia nitrogen pollution in the water and reducing harm to the environment.

[0064] Furthermore, water quality indicator monitoring includes ammonia nitrogen concentration monitoring, nitrate nitrogen concentration monitoring and pH value monitoring.

[0065] Regular monitoring of water quality indicators and equipment operating parameters can promptly detect and respond to problems that may arise during the treatment process, such as poor ammonia nitrogen removal and excessive sludge accumulation.

[0066] Furthermore, equipment operation parameter monitoring includes aeration volume monitoring, sludge return volume monitoring and mixed liquor temperature monitoring.

[0067] Monitoring data can provide important basis for subsequent process improvement and optimization.

[0068] The use process of a sewage treatment device with nitrification reaction provided by the present invention is as follows:

[0069] The sewage to be treated is introduced into the container 11 of the sewage treatment equipment through the input pipe 13, and the mixed liquid is introduced into the container 11 of the sewage treatment equipment through the mixed liquid pipe 110. The control motor 21 is started to make the stirring roller 32 rotate continuously. In the container 11, the sewage and the mixed liquid are fully mixed. At the same time, the piston 54 reciprocates longitudinally to input sufficient oxygen into the container 11 to maintain the dissolved oxygen concentration required by the nitrifying bacteria. Under suitable temperature, pH value and dissolved oxygen concentration conditions, the ammonia nitrogen in the sewage is oxidized into nitrite and nitrate under the action of nitrifying bacteria, so as to remove the ammonia nitrogen. After the nitrification reaction is completed, it enters the sedimentation tank through the output pipe 15 for solid-liquid separation, wherein the sludge part returns to the container 11 through the reflux pipe 14 to maintain the activity and quantity of the nitrifying bacteria in the container 11, and the supernatant is discharged as treated sewage.
