Abstract
Description

[0001] The invention belongs to the technical field of sewage treatment, and in particular is an integrated sewage treatment and recycling device. Background Art
[0002] The activated sludge method cultivates and proliferates microbial communities (called activated sludge) in an aeration tank, allowing these microorganisms to adsorb, absorb and degrade organic matter (such as carbohydrates, proteins, fats, etc.) in sewage. In this process, organic matter is converted into carbon dioxide, water and other inorganic substances, thereby achieving the purpose of purifying water quality. In the sewage activated sludge treatment method, adding flocculants is a common auxiliary process, which is mainly used to enhance the treatment effect, improve the sludge settling performance and improve the effluent water quality; the efficient application of flocculants is crucial to water purification, but the existing mixing equipment often makes it difficult to achieve full mixing of flocculants and sewage.

DETAILED DESCRIPTION
[0037] 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.
[0038] like Figures 1 to 8 As shown, the present invention provides an integrated sewage treatment and reuse device, including a pretreatment tank 1, a dissolution component 2, an aeration tank 3 and a sedimentation tank 4, the aeration tank 3 and the sedimentation tank 4 are connected, and also includes:
[0039] A mixing assembly 5, the mixing assembly 5 is used to connect the pretreatment tank 1 and the aeration tank 3;
[0040] A dissolving component 2, the dissolving component 2 is connected to the mixing component 5, and the dissolving component 2 is used for dissolving the flocculant;
[0041] The mixing assembly 5 includes a mixing tube 51, which is connected to the pretreatment tank 1 and the aeration tank 3. A second grid 58 is fixed inside the mixing tube 51, and a second cleaning strip 59 is arranged on the side of the second grid 58. The second cleaning strip 59 is made of corrosion-resistant material.
[0042] A guide tube 57 is fixedly installed inside the mixing tube 51. A through hole 52 is opened at one end of the guide tube 57, and the other end of the guide tube 57 is funnel-shaped.
[0043] The second cleaning strip 59 passes through the through hole 52 under the action of the water flow, and the outer diameter of the second cleaning strip 59 is smaller than the inner diameter of the through hole 52;
[0044] The other end of the guide tube 57 is fixedly mounted with a gathering cover 512 via a docking piece 511, and the inner wall of the gathering cover 512 is fixedly mounted with a guide ring 513 via a bracket;
[0045] The sewage in the pretreatment tank 1 and the flocculant in the dissolving component 2 enter the mixing tube 51 synchronously and pass through the through hole 52. Under the action of the water flow, the second cleaning bar 59 is driven to swing. At the same time, the sewage and the flocculant are mixed through the guide tube 57, the gathering cover 512 and the guide ring 513, and enter the aeration tank 3 through one end of the mixing tube 51.
[0046] The gap between the guide ring 513 and the gathering cover 512 gradually increases from the opening end of the gathering cover 512 inward;
[0047] The diameter of the opening of the guide ring 513 close to the gathering cover 512 is larger than the diameter of the other end of the guide tube 57.
[0048] A fixed amount of flocculant is injected into the dissolving component 2 for dissolution. The sewage in the pretreatment tank 1 and the flocculant in the dissolving component 2 enter the mixing tube 51 synchronously. The sewage and the flocculant flow through the through hole 52 in the mixing tube 51. Since the inner diameter of the through hole 52 is small, the sewage and the flocculant are diverted through multiple through holes 52, which can improve the mixing effect of the flocculant and the sewage. At the same time, since the second cleaning bar 59 passes through the inside of the through hole 52 and the outer diameter is smaller than the inside of the through hole 52, the second cleaning bar 59 swings in the through hole 52 under the action of the water flow, and the mixing efficiency of the sewage and the flocculant can be improved during the swinging process. At the same time, the sewage and the flocculant are gathered through one end of the guide tube 57 and enter the gathering cover 512 to achieve collision, and are dispersed along the gathering cover 512 and the guide ring 513, so that the sewage and the flocculant are mixed more fully in this reciprocating manner. The mixed sewage and flocculant enter the aeration box 3 through the mixing tube 51 for aeration treatment, which further improves the sewage flocculation efficiency.
[0049] At the same time, by swinging the second cleaning bar 59 in the through hole 52, impurities in the sewage can be prevented from adhering to the inner wall of the through hole 52. According to actual needs, bumps can be added to the surface of the second cleaning bar 59 to improve the effect of cleaning the attachments on the inner wall of the through hole 52.
[0050] like Figure 2-Figure 6As shown, the mixing assembly 5 further includes a second support frame 53 fixedly mounted on the inner wall of the mixing tube 51, and an impeller 54 is movably mounted on the second support frame 53;
[0051] The impeller 54 is located at one end of the connection between the dissolving component 2 and the mixing tube 51 close to the aeration box 3 .
[0052] The sewage and the flocculant enter the interior of the mixing tube 51 synchronously, and the impeller 54 is driven to rotate by the water flow. During the rotation, the flocculant is dispersed and filled in the interior of the mixing tube 51, so that the flocculant and the sewage enter the interior of the guide tube 57 more evenly.
[0053] like Figure 2-Figure 6 As shown, a first grid frame 55 is fixedly mounted on one end of the impeller 54, and a first cleaning strip 56 is disposed on the side of the first grid frame 55;
[0054] The outer wall of the first grid 55 is in contact with the inner wall of the mixing tube 51;
[0055] The first grid frame 55 and the first cleaning bar 56 rotate along with the impeller 54 , and the first cleaning bar 56 contacts the second grid frame 58 .
[0056] The first grid 55 and the first cleaning bar 56 rotate with the impeller 54, and the first cleaning bar 56 is driven to swing under the action of the water flow. The impurities attached to the surface of the second grid 58 are cleaned by the first cleaning bar 56. At the same time, the first cleaning bar 56 contacts the second cleaning bar 59 during the swinging process, which can increase the swinging arc of the second cleaning bar 59.
[0057] like Figure 6-Figure 8 As shown, the dissolution assembly 2 includes a dissolution box 21, which is connected to the mixing tube 51 through a butt joint 211. A water injection pipe 22 is fixed inside the dissolution box 21, and one end of the water injection pipe 22 is connected to the sedimentation box 4.
[0058] The water injection pipe 22 draws purified water from the interior of the sedimentation tank 4 through a water pump;
[0059] A dissolution aiding block 23 is movably arranged inside the dissolution box 21, and the dissolution aiding block 23 is movably sleeved on the outside of the water injection pipe 22, and a guide groove 24 is provided on the outside of the dissolution aiding block 23;
[0060] The dissolving component 2 further includes a first support frame 225 fixedly mounted inside the mixing tube 51, on which a movable rod 222 is movably mounted, and the movable rod 222 is connected to the impeller 54 via a connecting shaft 224, and the connecting shaft 224 is non-centrally connected to the movable rod 222 and the impeller 54;
[0061] A docking frame 226 is fixedly mounted at the bottom of the auxiliary solution block 23, a connecting rod 221 is fixedly mounted at the bottom of the docking frame 226, and the bottom of the connecting rod 221 is connected to the connecting shaft 224 through a transmission rod 223;
[0062] A first fixing plate 212 is fixedly installed inside the butt joint tube 211, a second fixing plate 213 is fixedly installed outside the connecting rod 221, the second fixing plate 213 is movably sleeved inside the butt joint tube 211, a second one-way valve 215 and a first one-way valve 214 are respectively provided on the first fixing plate 212 and the second fixing plate 213, and a protective mesh plate 216 is provided on the top of the dissolution box 21.
[0063] A quantitative flocculant is injected into the dissolving box 21, and the flocculant falls into the lower end of the dissolving box 21 through the guide groove 24 along the top surface curvature of the desolvation aid block 23. The purified water in the sedimentation box 4 is pumped into the dissolving box 21 by a water pump. The water impacts the solid flocculant in the dissolving box 21, dissolves the solid flocculant, and avoids the solid flocculant from agglomerating, thereby achieving the purpose of reusing purified water.
[0064] The sewage in the pretreatment tank 1 enters the mixing tube 51, and the impeller 54 is driven to rotate by the water flow. Since the connecting shaft 224 is non-centrally connected to the impeller 54 and the movable rod 222, the auxiliary dissolving block 23 is driven to reciprocate up and down through the transmission rod 223 and the connecting rod 221. When the auxiliary dissolving block 23 moves upward, the water and solid flocculants in the guide groove 24 will gather at the lower end of the dissolving tank 21, and when the auxiliary dissolving block 23 moves downward, the flocculants at the bottom of the dissolving tank 21 are squeezed and moved upward along the guide groove 24, so as to achieve the purpose of dissolving the solid flocculants and further avoid the phenomenon of agglomeration.
[0065] At the same time, when the connecting rod 221 moves downward, it drives the second fixed plate 213 to move downward in the docking tube 211. At this time, negative pressure is formed in the docking tube 211, and the second one-way valve 215 opens the flocculant in the dissolution box 21 to enter the docking tube 211, while the first one-way valve 214 is in a closed state, and the undissolved solid flocculant is blocked by the protective mesh plate 216. When the connecting rod 221 moves upward, the second fixed plate 213 moves upward along the docking tube 211, the first one-way valve 214 is in an open state, and the second one-way valve 215 is in a closed state. The flocculant in the docking tube 211 enters the interior of the mixing tube 51 through the first one-way valve 214, and is injected into the interior of the mixing tube 51 through the reciprocating up and down movement of the second fixed plate 213 to be evenly mixed with the sewage.
[0066] At the same time, the above steps can be applied to liquid flocculants.
[0067] The working principle and use process of the present invention:
[0068] A quantitative flocculant is injected into the dissolving box 21, and the flocculant falls into the lower end of the dissolving box 21 through the guide groove 24 along the top surface curvature of the desolvation aid block 23. The purified water in the sedimentation box 4 is pumped into the dissolving box 21 by a water pump, and the water impacts the solid flocculant in the dissolving box 21 to dissolve the solid flocculant.
[0069] The sewage in the pretreatment tank 1 enters the mixing tube 51, and the impeller 54 is driven to rotate by the water flow. Since the connecting shaft 224 is non-centrally connected to the impeller 54 and the movable rod 222, the auxiliary dissolving block 23 is driven to reciprocate up and down through the transmission rod 223 and the connecting rod 221. When the auxiliary dissolving block 23 moves upward, the water and solid flocculants in the guide groove 24 will gather at the lower end of the dissolving tank 21, and when the auxiliary dissolving block 23 moves downward, the flocculants at the bottom of the dissolving tank 21 are squeezed and moved upward along the guide groove 24, so as to achieve the purpose of dissolving the solid flocculants and further avoid the phenomenon of agglomeration.
[0070] At the same time, when the connecting rod 221 moves downward, the second fixed plate 213 is driven to move downward in the butt joint 211. At this time, negative pressure is formed in the butt joint 211. The second one-way valve 215 opens the flocculant in the dissolution box 21 and enters the butt joint 211, while the first one-way valve 214 is in a closed state, and the undissolved solid flocculant is blocked by the protective mesh plate 216. When the connecting rod 221 moves upward, the second fixed plate 213 moves upward along the butt joint 211, the first one-way valve 214 is in an open state, and the second one-way valve 215 is in a closed state. The flocculant in the butt joint 211 enters the interior of the mixing tube 51 through the first one-way valve 214, and the flocculant is injected into the interior of the mixing tube 51 through the reciprocating up and down movement of the second fixed plate 213;
[0071] The sewage and flocculant enter the interior of the mixing tube 51, and the impeller 54 is driven to rotate by the water flow. The flocculant is dispersed during the rotation and filled in the interior of the mixing tube 51, so that the flocculant and the sewage enter the interior of the guide tube 57 more evenly. The sewage and the flocculant flow through the through hole 52 in the mixing tube 51. Since the inner diameter of the through hole 52 is small, the sewage and the flocculant are diverted through multiple through holes 52, which can improve the mixing effect of the flocculant and the sewage. At the same time, since the second cleaning strip 59 passes through the through hole The second cleaning strip 59 is inside the through hole 52, and its outer diameter is smaller than that of the inside of the through hole 52. The second cleaning strip 59 swings in the through hole 52 under the action of the water flow. The mixing efficiency of the sewage and the flocculant can be improved during the swinging process. At the same time, the sewage and the flocculant are gathered through one end of the guide tube 57 and enter the gathering cover 512 to achieve collision, and are dispersed between the gathering cover 512 and the guide ring 513, so that the sewage and the flocculant are mixed more fully in this reciprocating manner. The mixed sewage and flocculant enter the aeration box 3 through the mixing tube 51 for aeration treatment.
