[0025] When carrying out the wastewater purification and recycling work, first, the wastewater is introduced into the pretreatment mechanism 5, and the pretreatment mechanism 5 filters the suspended pollutants in the wastewater. Subsequently, the wastewater is introduced into the circulating aeration mechanism 6. In the circulating aeration mechanism 6, the microorganisms in the activated sludge adsorb and oxidize and decompose the organic pollutants in the sewage, converting them into carbon dioxide, water and new microbial cytoplasm. Then, the aerated mixture is flowed into the sedimentation mechanism 7, and solid-liquid separation is achieved through gravity sedimentation. The activated sludge flocs sink to the bottom of the pool, and the supernatant becomes clarified treated water for recycling. In the existing activated sludge method, a primary sedimentation tank, an aeration tank and a secondary sedimentation tank are usually set up independently to cooperate in the sewage treatment work. However, the integrated device of the present invention integrates pretreatment, aeration and sedimentation into an integrated device. By driving the rotating collar 3 to drive several groups of transmission collars 4 to rotate, the pretreatment mechanism 5, the circulating aeration mechanism 6 and the sedimentation mechanism 7 are driven to rotate synchronously, and the internal structure is driven to carry out the corresponding wastewater treatment work during the rotation process, which is not only more energy-saving and environmental-friendly, but also improves the convenience of the wastewater purification and recycling work.

[0027] When performing the pretreatment of wastewater, first, the sewage is introduced into the pretreatment barrel 501 through the sewage inlet 502, and then the control drive collar 4 is controlled to drive the pretreatment barrel 501 to rotate. During the rotation of the pretreatment barrel 501, under the meshing connection relationship between the first gear 509 and the external gear ring 9, the first gear 509 drives the second lead screw 503 to rotate. Under the threaded connection relationship between the second lead screw 503 and the filter frame 504, the filter frame 504 moves downward, and the filter screen 505 directly presses the suspended pollutants in the wastewater to the bottom of the pretreatment barrel 501, facilitating the subsequent introduction of the wastewater into the circulating aeration mechanism 6 from above the filter frame 504. Moreover, the rotating block 507 rotatably connected to the bottom of the filter frame 504 is threadedly connected to the second lead screw 503, so that the rotating block 507 drives several groups of scraping plates 508 to clean the bottom of the filter frame 504, preventing the suspended pollutants from adhering and blocking the filter screen 505, and improving the wastewater pretreatment effect of the wastewater purification and recycling integrated equipment.

[0028] Exemplarily, such as Figure 5 、 Figure 6 and Figure 7As shown, the circulating aeration mechanism 6 includes an aeration barrel 601; a sludge guiding inner pipe 602 is rotatably connected to the center of the bottom inner wall of the aeration barrel 601; the bottom of the sludge guiding inner pipe 602 extends below the aeration barrel 601 and is drivingly connected to a second gear 603; the second gear 603 is meshed with an outer gear ring 9; an air guiding outer pipe 604 is sleeved on the outer wall of the sludge guiding inner pipe 602; a plurality of groups of stirring rods 605 are evenly distributed on the outer wall of the air guiding outer pipe 604; each group of stirring rods 605 is provided with a sludge guiding cavity 609 and an air guiding cavity 610; the sludge guiding cavity 609 is communicated with the sludge guiding inner pipe 602; the air guiding cavity 610 is communicated with the gap between the inner wall of the air guiding outer pipe 604 and the sludge guiding inner pipe 602; the sludge guiding cavity 609 is located above the air guiding cavity 610, and a plurality of groups of sludge discharging holes 611 are equidistantly arranged at the top; a plurality of groups of air discharging holes 612 are equidistantly arranged at the top of the air guiding cavity 610; an air guiding ring 606 is movably sleeved on the top outer wall of the air guiding outer pipe 604; the air guiding ring 606 is communicated with the gap between the inner wall of the air guiding outer pipe 604 and the sludge guiding inner pipe 602; the air guiding ring 606 is communicated with the output end of the aerator 14; a first spiral push rod 607 is arranged in the sludge guiding inner pipe 602; the top of the first spiral push rod 607 extends above the sludge guiding inner pipe 602 and is drivingly connected to a third gear 608; the third gear 608 is meshed with an inner gear ring 15.

[0029] When carrying out the aeration treatment work of wastewater, the sewage is transferred from the pretreatment barrel 501 into the aeration barrel 601, and then the driving sleeve ring 4 is controlled to drive the aeration barrel 601 to rotate. During the rotation of the aeration barrel 601, since the second gear 603 is meshed with the outer gear ring 9 and the third gear 608 is meshed with the inner gear ring 15, the sludge guiding inner pipe 602 drives a plurality of groups of stirring rods 605 to rotate through the air guiding outer pipe 604 to disturb the wastewater. At the same time, the first spiral push rod 607 rotates in the opposite direction to the sludge guiding inner pipe 602, and a through groove for the entry of activated sludge is formed on the bottom outer wall of the sludge guiding inner pipe, so that the activated sludge accumulated at the bottom of the aeration barrel 601 is pushed upward by the first spiral push rod 607 and discharged from a plurality of sludge discharging holes 611 through the sludge guiding cavity 609 to the surface of the stirring rods 605. At the same time, the aerator 14 accurately introduces air into the sludge guiding cavity 609 through the air guiding ring 606, the air guiding outer pipe 604, the air guiding cavity 610 and a plurality of groups of air discharging holes 612 to be combined with the activated sludge, which not only avoids the problem of the accumulation of activated sludge, improves the purification effect of the wastewater, but also improves the oxygen supply effect for microorganisms.

[0030] Exemplarily, as Figure 8 and Figure 9 shown, the precipitation mechanism 7 includes a precipitation barrel 701; a sludge recovery assembly 702 is arranged at the bottom of the precipitation barrel 701.

[0031] The sludge recovery component 702 includes a sludge recovery pipe 7021; a sludge chamber 7022 and a power chamber 7023 are provided in the sludge recovery pipe 7021; the sludge chamber 7022 is communicated with the circulating aeration mechanism 6; a recovery through groove 7024 is opened at the top of the sludge chamber 7022; a second spiral push rod 7025 is provided in the sludge chamber 7022; an arc-shaped sealing plate 7026 is provided at the bottom of the sludge chamber 7022; a recovery motor 7027 is provided in the power chamber 7023; and the output end of the recovery motor 7027 is in transmission connection with the second spiral push rod 7025.

[0032] After the wastewater purification work is completed, the mixed liquid is transferred from the circulating aeration mechanism 6 to the sedimentation tank 701. After standing, the activated sludge accumulates at the bottom of the sedimentation tank 701 and enters the sludge chamber 7022 through the recovery through groove 7024. Subsequently, the second spiral push rod 7025 is controlled to rotate to push the activated sludge into the circulating aeration mechanism 6. When the volume of the activated sludge in the circulating aeration mechanism 6 reaches the corresponding volume, the arc-shaped sealing plate 7026 opens to discharge the activated sludge to the outside of the equipment, improving the recycling effect and recovery efficiency of the activated sludge of the integrated wastewater purification and recovery equipment.

[0033] By controlling the aeration barrel 601 to rotate around the support column 2, during the rotation of the aeration barrel 601, the mud guiding inner pipe 602 rotates and drives a plurality of groups of stirring rods 605 to rotate through the air guiding outer pipe 604 to disturb the wastewater. And the first spiral push rod 607 rotates in the opposite direction to the mud guiding inner pipe 602, so that the activated sludge accumulated at the bottom of the aeration barrel 601 is pushed upward by the first spiral push rod 607 and discharged to the surface of the stirring rods 605 through the mud guiding cavity 609 from a plurality of groups of mud discharging holes 611. At the same time, air enters the mud guiding cavity 609 through the air guiding ring 606, the air guiding outer pipe 604, the air guiding cavity 610 and a plurality of groups of exhaust holes 612 to be precisely combined with the activated sludge, not only avoiding the accumulation problem of the activated sludge, improving the purification effect of the wastewater, but also improving the oxygen supply effect of the microorganisms.

[0034] By controlling the rotation of the second lead screw 503, under the threaded connection relationship between the second lead screw 503 and the filter frame 504, the filter frame 504 moves downward, and the filter screen 505 directly presses the suspended pollutants in the wastewater to the bottom of the pretreatment barrel 501, facilitating the subsequent introduction of the wastewater into the circulating aeration mechanism 6 from above the filter frame 504. And the rotating block 507 rotatably connected to the bottom of the filter frame 504 is in threaded connection with the second lead screw 503, so that the rotating block 507 drives a plurality of groups of scraping plates 508 to clean the bottom of the filter frame 504, avoiding the suspension pollutants from adhering to and blocking the filter screen 505, and improving the wastewater pretreatment effect of the integrated wastewater purification and recovery equipment.

[0035] After the wastewater purification work is completed, the mixed liquid is transferred from the circulating aeration mechanism 6 to the sedimentation tank 701. After standing still, the activated sludge accumulates at the bottom of the sedimentation tank 701 and enters the sludge chamber 7022 through the recovery trough 7024. Subsequently, the second spiral push rod 7025 is controlled to rotate to push the activated sludge into the circulating aeration mechanism 6. When the volume of the activated sludge in the circulating aeration mechanism 6 reaches the corresponding volume, the arc-shaped sealing plate 7026 opens to discharge the activated sludge to the outside of the equipment, improving the recycling effect and recovery efficiency of the activated sludge in the integrated wastewater purification and recovery equipment.

[0036] In the existing activated sludge process, a primary sedimentation tank, an aeration tank, and a secondary sedimentation tank are usually set up independently to cooperate in the sewage treatment work. However, the integrated equipment of the present invention integrates pretreatment, aeration, and sedimentation into an integrated equipment. By driving the rotating collar 3 to drive several groups of transmission collars 4 to rotate, the pretreatment mechanism 5, the circulating aeration mechanism 6, and the sedimentation mechanism 7 are driven to rotate synchronously, and the internal structure is driven to perform corresponding wastewater treatment work during the rotation process, which is not only more energy-saving and environmentally friendly but also improves the convenience of the wastewater purification and recovery work.

[0037] Based on the above-mentioned energy-saving and environmentally friendly integrated wastewater purification and recovery equipment, the embodiment of the present invention also proposes a working method for the energy-saving and environmentally friendly integrated wastewater purification and recovery equipment. Exemplarily, the working method includes: Introduce the wastewater into the pretreatment mechanism; Control the rotating collar to drive the pretreatment mechanism, the circulating aeration mechanism, and the sedimentation mechanism to rotate; The pretreatment mechanism filters the suspended pollutants in the wastewater and introduces the filtered wastewater into the circulating aeration mechanism; The inner mud guide tube in the circulating aeration mechanism rotates and drives several groups of stirring rods to disturb the wastewater through the outer air guide tube; The first spiral push rod pushes the sludge accumulated at the bottom of the aeration tank in the opposite direction of the rotation of the inner mud guide tube to discharge through the mud guide cavity and the mud discharge holes on the stirring rods; Air is precisely combined with the activated sludge in the mud guide cavity through the outer air guide tube, the air guide cavity, and several groups of exhaust holes; After the aeration work is completed, introduce the mixed liquid into the sedimentation mechanism for standing still; The sedimentation mechanism circulates and recovers the precipitated activated sludge; Complete the wastewater purification and recovery work.
