Description

[0033] Example 1

[0034] This invention provides a wastewater treatment device for cyhalofop-butyl production, such as... Figures 1-10 As shown, it includes: an aeration tank 1, a baffle 2 is set in the center of the aeration tank 1, gaps are set between the left and right ends of the baffle 2 and the inner wall of the aeration tank 1, a number of aeration mechanisms 3 are set in the aeration tank 1, the number of aeration mechanisms 3 are symmetrically arranged on the front and rear sides of the baffle 2, and a drive mechanism 4 is set on the left and right sides of the aeration tank 1. The two drive mechanisms 4 are centrally symmetrically distributed about the center of the baffle 2. The drive mechanism 4 is used to drive the wastewater to circulate in the aeration tank 1.

[0035] The working principle and beneficial effects of the above technical solution are as follows: the baffle 2 at the center of the aeration tank 1 can divide the aeration tank 1 into two treatment areas, and there is a gap between the left and right ends of the baffle 2 and the aeration tank 1, so that the left and right ends of the two treatment areas are communicated. The sludge is arranged in the aeration tank 1, and when the wastewater is introduced into the aeration tank 1, the aeration mechanism 3 is started to introduce oxygen into the sludge through the aeration mechanism 3. Then the driving mechanism 4 is started, and under the driving action of the driving mechanism 4, the wastewater and sludge flow from the gap at one end of the baffle 2, flow along one side of the baffle 2 to the gap at the other end, flow into the other side of the baffle 2 through the gap at the other end, and form a stable circulation under the action of the baffle 2. The circulation of wastewater and sludge is realized, so that the sludge at different positions can be aerated. At the same time, oxygen is continuously introduced into the aeration tank 1 through the aeration mechanism 3, and the generated bubbles diffuse in the wastewater and sludge in the aeration tank 1, so that the wastewater and sludge are fully mixed with oxygen during the circulation process. The wastewater forms a stable circulation in the aeration tank 1 by the baffle 2 and the driving mechanism 4, effectively reducing the water flow dead angle that is prone to occur in the traditional aeration tank 1, ensuring that the oxygen generated by the aeration mechanism 3 can be uniformly diffused to each area in the aeration tank 1, and reducing the number of aeration mechanisms 3 arranged, thereby reducing the maintenance cost. The uniform aeration makes the distribution of dissolved oxygen in the wastewater more balanced, providing a good survival and metabolism environment for microorganisms, greatly improving the oxidation and decomposition efficiency of microorganisms on complex organic matter in cyhalofop-butyl production wastewater, significantly enhancing the treatment capacity and stability of the wastewater treatment equipment, and making the effluent quality more easily meet the discharge standard, thereby realizing efficient purification treatment of cyhalofop-butyl production wastewater.

[0036] Example 2

[0037] Based on the above example 1, as shown in Figure 1 The four corners of the aeration tank 1 are respectively provided with flow guide blocks 5, and the inner side of the flow guide block 5 is a concave arc surface.

[0038] The working principle and beneficial effects of the above technical solution are as follows: when the circulating wastewater reaches the corners of the aeration tank 1, the concave arc surface on the inner side of the flow guide block 5 will have a guiding effect on the wastewater, and the wastewater will change its flow direction along the arc of the arc surface, thereby reducing the fluid resistance and making the wastewater and sludge that are prone to form vortex or stagnation in the corners smoothly flow into the circulation flow path. The accumulation of wastewater or sludge in the four corners of the aeration tank 1 is avoided, the stable circulation of wastewater is maintained, and the circulation of wastewater in the tank is more smooth and efficient. At the same time, the bubbles generated by the aeration mechanism 3 will also diffuse in the direction of wastewater flow under the driving of the wastewater, and fully contact with the wastewater, thereby ensuring that the wastewater in the entire aeration tank 1 can participate in the circulation and receive uniform aeration, improving the mass transfer efficiency of dissolved oxygen, and further optimizing the survival environment of microorganisms.

[0039] Example 3

[0040] On the basis of Embodiment 1 or 2, as shown in Figure 3 The driving mechanism 4 includes a mixing pipe 6, which is arranged on the side wall of the aeration tank 1, one end of the mixing pipe 6 extends into the aeration tank 1 and is provided with a spray head 7, a plurality of spray holes 8 are arranged in the spray head 7, and the other end of the mixing pipe 6 extends to the outside of the aeration tank 1 and is provided with a convection pipe 9, which is perpendicular to the mixing pipe 6, one end of the convection pipe 9 is provided with an air inlet pipe 10, and the first valve is arranged on the air inlet pipe 10.

[0041] The working principle and beneficial effects of the above technical scheme are as follows: when the driving mechanism 4 is started, the first valve is opened, external air flows into the convection pipe 9 through the air inlet pipe 10, and then flows into the mixing pipe 6 through the convection pipe 9, the air is quickly sprayed into the aeration tank 1 through the plurality of spray holes 8 of the spray head 7, the spray holes 8 are horizontally arranged, so that the air can be sprayed horizontally, thereby driving the wastewater in the aeration tank 1 to flow, and the two groups of driving mechanisms 4 are centrally symmetrically distributed about the center of the partition plate 2, one of the spray heads 7 is located on the front side of the partition plate 2, and the other spray head 7 is located on the rear side of the partition plate 2, as the air is continuously sprayed, the wastewater in the aeration tank 1 can be driven to circulate in the aeration tank 1, thereby forming a stable circulation, which can effectively stir the wastewater and complete the aeration treatment of the wastewater together with the aeration mechanism 3, avoids the sedimentation of sludge in the aeration tank 1, and enables the wastewater, sludge and oxygen in the aeration tank 1 to fully contact, promotes the oxidation and decomposition of organic matter in the cyhalofop-butyl production wastewater by microorganisms, and significantly improves the treatment capacity and treatment effect of the wastewater treatment equipment.

[0042] Embodiment 4

[0043] On the basis of Embodiment 3, as shown in Figure 3 The air inlet pipe 10 is provided with a second valve.

[0044] The working principle and beneficial effects of the above technical solution are as follows: in the wastewater treatment process, when it is necessary to add medicaments or microbial inoculants and other additives to the aeration tank 1, the second valve on the feed pipe 11 can be opened, the additives are added to the convection pipe 9 through the feed pipe 11, and are mixed with air in the mixing pipe 6, and then are sprayed into the aeration tank 1 from the spray holes 8 of the spray head 7. With the circulating flow of the wastewater, the additives can be uniformly diffused to each area of the aeration tank 1. In the adding process, no additional stirring equipment is needed, the operating cost is reduced, and the activity and metabolic function of the microorganisms are not adversely affected due to excessive stirring. By fully mixing the additives with air before spraying, the rapid and uniform diffusion of the medicaments or microbial inoculants and other additives in the aeration tank 1 can be ensured, the problems of local high concentration or uneven distribution can be avoided, and the medicament reaction efficiency and the microbial treatment effect can be significantly improved. When liquid additives are added, taking liquid glucose as an example, the glucose added through the feed pipe 11 can be sprayed out in the form of bubbles after being mixed with air, which can make the liquid glucose more uniformly dispersed in the aeration tank 1, and the microorganisms can better contact with the glucose and oxygen, which is beneficial to the microorganisms to uniformly obtain glucose as a carbon source in the aeration tank 1, and improves the metabolic efficiency of the microorganisms and the treatment effect on the wastewater.

[0045] Embodiment 5

[0046] On the basis of embodiment 4, as shown in Figures 3-6 The mixing assembly is arranged in the mixing pipe 6, and the mixing assembly includes a mixing shaft 12. The mixing shaft 12 is arranged in the mixing pipe 6, one end of the mixing shaft 12 extends to the outside of the convection pipe 9 and is connected with the output end of a mixing motor 13. A plurality of mixing plates 14 are arranged on the mixing shaft 12, and the plurality of mixing plates 14 are arranged at equal intervals.

[0047] The working principle and beneficial effects of the above technical solution are as follows: the mixing motor 13 can drive the mixing shaft 12 to rotate, the mixing shaft 12 drives the mixing plates 14 to rotate synchronously, the air and the additives in the mixing pipe 6 are stirred by the mixing plates 14, so that the air and the additives are fully mixed, the mixing effect of the air and the additives is enhanced, and the mixing efficiency is improved.

[0048] Embodiment 6

[0049] On the basis of embodiment 5, a first flow limiting plate 15 and a second flow limiting plate 16 are arranged on both sides of the mixing plate 14 respectively. The outer wall of the first flow limiting plate 15 is connected with the inner wall of the mixing pipe 6, the inner diameter of the first flow limiting plate 15 is greater than the diameter of the mixing shaft 12.

[0050] The working principle and beneficial effects of the above technical solution are as follows: After the air and additives enter the mixing pipe 6, they first pass through the center of the first flow restrictor, and then are stirred and mixed by the mixing plate 14. Then, they flow through the edge of the second flow restrictor 16 to the next first flow restrictor 15, thereby extending the path of the air and additives in the mixing pipe 6, increasing the contact and mixing time between the air and additives, making the mixing of the air and additives more thorough, and providing sufficient time for the mixing plate 14 to stir, thus improving the uniformity of the air and additives mixture. By setting the second flow restrictor 16, the mixture of air and additives flowing out can be guided, avoiding the generation of disordered vortices in the mixture due to the high-speed rotation of the mixing plate 14, so that the mixture is sprayed into the aeration tank 1 from the nozzle 8 in a more stable state, ensuring the uniformity and stability of the sprayed mixture, and improving the stability of the wastewater circulation flow in the aeration tank 1.

[0057] On the basis of any one of examples 1-7, as shown in Figure 8 、 Figure 10 The driving motor 30 is arranged on the partition plate 2, the first bevel gear 31 is arranged at the output end of the driving motor 30, the second bevel gears 32 are symmetrically arranged on the front and back of the first bevel gear 31, the driving shaft 33 is arranged on the side away from each other of the two second bevel gears 32, the driving shaft 33 is rotationally connected with the fixed plate 34, the fixed plate 34 is arranged on the partition plate 2, and the agitating plate 35 is arranged on the outer wall of the driving shaft 33.

[0058] The working principle and beneficial effects of the above technical scheme are: the driving motor 30 is further arranged on the partition plate 2, when the driving mechanism 4 is insufficient in power, the driving motor 30 is started to drive the first bevel gear 31 to rotate, the first bevel gear 31 drives the second bevel gears 32 on the front and rear sides to synchronously rotate, the second bevel gears 32 drive the driving shaft 33 to rotate, the driving shaft 33 drives the stirring plate 35 to rotate, the lowermost end of the stirring plate 35 can stir the wastewater, so that the wastewater flows away from the driving mechanism 4, the stirring of the stirring plate 35 is beneficial to the stable flow of the wastewater, avoids the sedimentation of sludge, and ensures that the microorganisms are in full contact with the wastewater.

[0059] Example 9

[0060] On the basis of any one of examples 1-8, as shown in Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 The flow guide plate 36 is arranged between the two adjacent aeration mechanisms 3, the arc-shaped surface of the flow guide plate 36 protrudes outward near the driving mechanism 4, the lower side of the flow guide plate 36 is rotationally connected to the bottom wall of the aeration tank 1 through the rotating column 42, a plurality of guide grooves 37 are arranged in the flow guide plate 36, the plurality of guide grooves 37 are arranged at equal intervals, the fixed column 38 is arranged at one end of the flow guide plate 36 close to the partition plate 2, the driving blocks 39 are symmetrically arranged at the left and right ends of the fixed column 38, the driving blocks 39 are semispherical, the driving plates 40 are arranged at the side of the driving blocks 39 away from the fixed column 38, the centers of the two adjacent driving plates 40 are connected through the connecting column, the electric push rod 41 is arranged on the partition plate 2, and the output end of the electric push rod 41 is connected to the upper end of the driving plate 40.

[0061] The working principle and beneficial effects of the above technical scheme are as follows: when the flow of the mixture sprayed by the spray hole 8 is large, the wastewater flows in the aeration tank 1, part of the wastewater is blocked by the guide plate 36 and flows along the surface of the guide plate 36, and the other part of the wastewater flows to the other side of the guide plate 36 through the guide groove 37. At this time, there is a certain angle between the guide groove 37 and the partition plate 2 in the aeration tank 1, the guide grooves 37 in the adjacent two guide plates 36 are cross-distributed, the guide groove 37 is in an inclined state, the wastewater flows out along the inclined guide groove 37, the flow path of part of the wastewater is increased, and the overall flow rate of the wastewater is further slowed down. By arranging the guide plate 36, the flow rate of the wastewater can be reduced, so that the wastewater in the aeration tank 1 flows slowly and will not cause damage to the microorganisms due to violent flow, the activity of the sludge in the aeration tank 1 is ensured, the service life of the activated sludge is prolonged, and the operation cost is reduced. When the flow of the mixture sprayed by the spray hole 8 is small, the wastewater circulating flow is insufficient, which may cause the sludge to precipitate and affect the uniform diffusion of oxygen. At this time, the electric push rod 41 is controlled to retract, the electric push rod 41 drives the driving plate 40 to move, the driving plate 40 drives the driving block 39 to move, the driving block 39 drives the guide plate 36 to rotate around the rotating column 42 through the fixing column 38, so as to adjust the angle of the guide plate 36 until the guide groove 37 is parallel to the partition plate 2. At this time, the wastewater flowing through the guide groove 37 can shorten the flow path of the wastewater, the gap between the guide plate 36 and the inner wall of the aeration tank 1 is also increased, which is further beneficial to the flow of the wastewater and reduces the obstruction of the wastewater flow, ensuring the stability of the wastewater circulating flow in the aeration tank 1 and ensuring that the oxygen generated by the aeration mechanism 3 can be uniformly diffused to each area in the aeration tank 1, so as to provide a good survival and metabolism environment for the microorganisms. The oxidation and decomposition efficiency of the microorganisms on the complex organic matter in the production wastewater of cyhalofop-butyl is greatly improved, and the treatment capacity and stability of the wastewater treatment equipment are further enhanced.
