Wastewater treatment is widely used in construction, agriculture, food processing, transportation, energy and other fields. Among them, a large amount of fermentation wastewater is generated in the production process of food processing, brewing and pharmaceutical industries. Since the content of organic matter and suspended matter in fermentation wastewater is significantly higher, a large amount of ozone gas is required to decompose the organic matter, and a large amount of flocculants are required to settle the suspended matter. Therefore, it is difficult to efficiently treat fermentation wastewater using general wastewater treatment equipment.

[0003] A Chinese patent with announcement number "CN112811570B" discloses a wastewater ozone oxidation deep treatment device, including a device body, which is divided into a sedimentation chamber and an ozone treatment chamber by a partition.

[0013] Preferably, a comprehensive treatment process for fermentation wastewater using a comprehensive treatment device for fermentation wastewater comprises the following steps:

[0014] a: First, put the fermentation wastewater and flocculant into the tank, and introduce ozone into the air inlet pipe, so that the driving motor drives the drum to rotate forward, and the fermentation wastewater and flocculant are stirred and mixed. At the same time, the gas collecting shield collects the ozone gas gathered on the top of the tank again and discharges it from the diffuser hole, so that the ozone can fully decompose the organic matter;

[0015] b: When one set of gas collecting shields rotates to the bottom of the tank, the electric push rod is controlled to retract the push rod, and the drive motor is adjusted to rotate in the opposite direction, so that the wastewater circulates and the flocculated sediment is blocked by the filter plate, thus completing the cleaning operation of the flocculated sediment in the wastewater;

[0016] c: Control the electric push rod to extend the push rod, adjust the drive motor to rotate in the forward direction, the fixed ring brush contacts the filter plate and cleans the surface of the filter plate, and the flocculated sediment is collected in the storage bin, completing the collection and treatment of the flocculated sediment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a power mechanism, when the driving motor drives the driving shaft to rotate forward and controls the electric push rod to extend, the drum is driven to rotate, stirring and aerating the wastewater; when the driving motor rotates in the reverse direction and controls the electric push rod to retract, the drum stops rotating, the water inlet is connected with the connecting groove, the wastewater is introduced into contact with the filter disc, and the flocculated sediment therein is blocked by the filter disc, completing the cleaning operation;

[0019] 2. By setting up a rotating drum, the wastewater can be stirred to promote the mixing of wastewater and flocculant. At the same time, the ozone gas floating to the top of the tank is collected and pressed down by the gas collecting shield. Under the combined effect of its own buoyancy and suction, the ozone gas moves to the inside of the rotating drum through the connecting pipe and is finally discharged from the diffuser hole, so that the unused ozone can contact with the wastewater for multiple times, thereby improving the utilization rate of ozone;

[0020] 3. By setting the filter disc, when the filter disc slides backward and away from the side wall of the tank, the water inlet contacts the connecting groove, and the wastewater can be continuously introduced into the front of the filter disc, and the filter disc blocks and cleans the flocculated sediment in the wastewater. When the filter disc slides forward and directly contacts the side wall of the tank, the water inlet is disconnected from the connecting groove, and the filter disc contacts the fixed ring brush. As the filter disc rotates, the flocculated sediment accumulated on the filter disc is cleaned off;

[0021] 4. By setting a plugging component, the plugging ring is controlled to move back and forth regularly to block or open the connecting pipe. When the connecting pipe rotates to the bottom of the tank, the plugging ring opens the connecting pipe so that the ozone gas inside the connecting pipe can smoothly enter the drum. When the connecting pipe rotates to the top of the tank, the plugging ring closes the connecting pipe, thereby preventing the ozone gas inside the drum from being directly discharged from the connecting pipe, and preventing the ozone gas from fully contacting the wastewater.

[0022] 5. By setting a reciprocating piston, the plug body is controlled to move back and forth regularly to squeeze or expand the space inside the drum. When the connecting pipe is connected to the inside of the drum, the plug body moves backward under the elastic force of the second compression spring, increasing the internal space of the drum, making the inside of the drum in a negative pressure state, and sucking the ozone gas in the connecting pipe into the drum. When the connecting pipes are not connected to the inside of the drum, the limiting top block on the plug body is squeezed by the top ear, pushing the plug body to overcome the elastic force of the second compression spring and move forward, reducing the internal space of the drum, making the inside of the drum in a high-pressure state, and discharging the ozone gas in the drum from the diffuser hole. The ozone gas is dispersed and contacts with the wastewater again to react. BRIEF DESCRIPTION OF THE DRAWINGS

Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0045] like Figure 1 and Figure 2 As shown, a comprehensive treatment device for fermentation wastewater includes a tank body 1, an air outlet pipeline 101 and a water inlet pipe 102 are fixedly provided on the top of the tank body 1, and the fermentation wastewater and flocculant to be treated are poured into the tank body 1 from the water inlet pipe 102, an air inlet pipe 105 and a leg 104 are fixedly provided at the bottom of the tank body 1, and a plurality of aeration holes 105A are fixedly provided on the air inlet pipe 105. After the ozone gas is introduced from the air inlet pipe 105, it is discharged from the aeration holes 105A, which can ensure that the ozone gas is more dispersed, increase the contact area between the ozone gas and the wastewater, and improve the utilization rate of the ozone; a water outlet pipe 103 is fixedly provided on the rear side wall of the tank body 1, a slide bar 106 is fixedly provided on the front outer wall of the tank body 1, and a discharge slot 107 is fixedly provided at the bottom of the slide bar 106;

[0046] like Figure 4As shown, a limiting ring 109 is fixedly provided at the center of the inner wall of the front part of the tank body 1, and the limiting ring 109 includes a first step 109A, a second step 109B is provided above the first step 109A, and a third step 109C is provided above the second step 109B, wherein the first step 109A is the shortest, and the third step 109C is the longest, and a plurality of groups of fixed ring brushes 110 are fixedly provided at the bottom of the limiting ring 109, and the fixed ring brushes 110 are arc-shaped, and when the filter disc 503 contacts the fixed ring brushes 110, the fixed ring brushes 110 can clean the flocculated sediment on the filter disc 503, and move the cleaned flocculated sediment to the surroundings, and finally discharge it into the storage bin 2 from the discharge slot 107;

[0047] like Figure 3 As shown, a top column 108 is fixedly provided at the center of the rear side wall of the tank body 1, and a top ear 108A is fixedly connected to the side wall of the top column 108. A power mechanism 3 is fixedly provided at the front of the tank body 1. By setting the power mechanism 3, when the driving motor 301 drives the driving shaft 304 to rotate forward and controls the electric push rod 302 to extend, the drum 4 is driven to rotate to stir and aerate the wastewater. When the driving motor 301 rotates in the reverse direction and controls the electric push rod 302 to retract, the drum 4 stops rotating, the water inlet 404 is connected to the connecting groove 502A, and the wastewater is introduced into the filter plate. 503, the flocculated sediment therein is blocked by the filter plate 503, and the cleaning operation is completed; the tank body 1 is rotatably connected with a rotating drum 4, and by setting the rotating drum 4, the wastewater can be stirred to promote the mixing of the wastewater and the flocculant, and at the same time, the ozone gas floating to the top of the tank body 1 is collected and pressed down by the gas collecting shield 407. Under the combined action of its own buoyancy and suction, the ozone gas moves to the inside of the rotating drum 4 through the connecting pipe 406 and is finally discharged from the diffuser hole 405, so that the unused ozone can contact the wastewater for multiple times, thereby improving the utilization rate of the ozone;

[0048] The outer wall of the drum 4 is slidably connected with a filter disc 5. By setting the filter disc 5, when the filter disc 5 slides backward and away from the side wall of the tank body 1, the water inlet 404 contacts the connecting groove 502A, and the wastewater can be continuously introduced into the front of the filter disc 5. The filter disc 5 blocks and cleans the flocculated sediment in the wastewater. When the filter disc 5 slides forward and directly contacts the side wall of the tank body 1, the water inlet 404 is disconnected from the connecting groove 502A, and the filter disc 5 contacts the fixed ring brush 110. As the filter disc 5 rotates, the flocculated sediment accumulated on the filter disc 5 is cleaned off; the inside of the drum 4 A plugging assembly 6 is provided at the front end. By setting the plugging assembly 6, the plugging ring 602 is controlled to move back and forth regularly to plug or open the connecting pipe 406. When the connecting pipe 406 rotates to the bottom of the tank body 1, the plugging ring 602 opens the connecting pipe 406, so that the ozone gas inside the connecting pipe 406 can smoothly enter the rotating drum 4. When the connecting pipe 406 rotates to the top of the tank body 1, the plugging ring 602 closes the connecting pipe 406, thereby preventing the ozone gas inside the rotating drum 4 from being directly discharged from the connecting pipe 406, and preventing the ozone gas from fully contacting with the wastewater.

[0049] A reciprocating piston 7 is provided at the rear end of the drum 4. The reciprocating piston 7 is provided to control the regular forward and backward movement of the plug body 702 to squeeze or expand the space inside the drum 4. When the connecting pipe 406 is connected to the inside of the drum 4, the plug body 702 moves backward under the elastic force of the second compression spring 701, thereby increasing the internal space of the drum 4, making the inside of the drum 4 in a negative pressure state, and sucking the ozone gas in the connecting pipe 406 into the drum 4. When the connecting pipe 406 is not connected to the inside of the drum 4, the limiting top block 702B on the plug body 702 is squeezed by the top ear 108A, pushing the plug body 702 to overcome the elastic force of the second compression spring 701 and move forward, reducing the internal space of the drum 4, making the inside of the drum 4 in a high-pressure state, and discharging the ozone gas in the drum 4 from the air diffusion hole 405, dispersing the ozone gas, and contacting and reacting with the wastewater again.

[0050] like Figure 5 , Fig.15 , Fig.16 , Fig.17 and Fig.18As shown, a chute 401 is fixedly provided inside the drum 4, a water inlet 404 is fixedly provided on the front side wall of the drum 4, a connecting pipe 406 is extended outward from the outer wall of the drum 4, and a gas gathering shield 407 is fixedly connected to the other end of the connecting pipe 406. As the gas gathering shield 407 rotates, the ozone gas gathered on the top of the tank body 1 is gathered again. As the gas gathering shield 407 continues to rotate downward, the ozone gas gradually enters the connecting pipe 406 upward under the action of buoyancy, and finally enters the inside of the drum 4, completing a gas gathering shield 407. The ozone gas is recovered and reacted. As the drum 4 continues to rotate, the ozone gas is recovered and reacted multiple times, thereby improving the utilization rate of the ozone gas. A plurality of groups of air diffusion holes 405 are fixedly provided on the side wall of the drum 4, and a one-way valve is fixedly installed inside the air diffusion holes 405. By setting the one-way valve, it is possible to prevent the waste water in the tank body 1 from accidentally entering the inside of the drum 4 through the air diffusion holes 405 when the inside of the drum 4 is in a negative pressure state. A front retaining ring 402 is fixedly connected to the inner wall of the front end of the drum 4, and a rear retaining ring 403 is fixedly connected to the inner wall of the rear end of the drum 4.

A sealing piece 1 602C is fixedly connected to the top of the mounting ring 602B, and a sealing piece 2 602D is fixedly connected to the bottom of the mounting ring 602B. Both the sealing piece 1 602C and the sealing piece 2 602D cooperate with the connecting pipe 406. The front part of the sealing piece 1 602C is fixedly connected to the mounting ring 602B, and the rear part of the sealing piece 2 602D is fixedly connected to the mounting ring 602B.

[0052] When the push rod 602A rotates to the bottom with the drum 4, the push rod 602A contacts the first step 109A. At this time, the blocking ring 602 moves to the frontmost position relative to the drum 4. The second blocking piece 602D does not contact its connecting pipe 406 at this time. The connecting pipe 406 here is connected to the drum 4. The rear end of the blocking piece 1 602C contacts its connecting pipe 406 to block its connecting pipe 406. When the push rod 602A rotates to a relatively horizontal position with the drum 4, the push rod 602A contacts the second step 109B. At this time, the blocking ring 602 moves to the frontmost position relative to the drum 4. The second blocking piece 602D does not contact its connecting pipe 406 at this time. The connecting pipe 406 here is connected to the drum 4. The rear end of the blocking piece 1 602C contacts its connecting pipe 406 to block its connecting pipe 406. The ring 602 moves backward for a distance relative to the rotating drum 4, and the right part of the sealing piece 2 602D and the left part of the sealing piece 1 602C both contact and seal its connecting pipe 406. When the top rod 602A rotates to the top with the rotating drum 4, the top rod 602A contacts the third step 109C. At this time, the sealing ring 602 moves to the rearmost position relative to the rotating drum 4, and the left part of the sealing piece 2 602D seals its connecting pipe 406. The sealing piece 1 602C does not contact its connecting pipe 406 at this time, and the connecting pipe 406 here remains connected with the rotating drum 4.

The front end of the compression spring 701 is fixedly connected to the rear retaining ring 403, and the rear end of the compression spring 701 is fixedly connected to the plug body 702. Under the elastic force of the compression spring 701, the plug body 702 maintains a tendency to move backward. A slide bar 702A is fixedly connected to the side wall of the plug body 702. The slide bar 702A is slidably connected to the slide groove 401. Under the limiting action of the slide bar 702A, the plug body 702 and the rotating drum 4 remain circumferentially fixed. The rear part of the plug body 702 is fixedly connected to a limiting top block 702B, and the limiting top block 702B cooperates with the top ear 108A. As the drum 4 rotates, the plug 702 regularly moves laterally to expand or shrink the internal space of the drum 4. When the limiting top block 702B contacts the top ear 108A, the plug 702 is squeezed forward. When the limiting top block 702B loses contact with the top ear 108A, the plug 702 is pushed backward by the compression spring 701. Every time the drum 4 rotates one circle, the plug 702 reciprocates twice.

When the mounting rack 501 slides to the front of the water outlet 404, the rear of the connecting rod 502 blocks the water outlet 404, and the water outlet 404 is closed. When the mounting rack 501 slides to the rear of the water outlet 404, the connecting groove 502A at the front of the connecting rod 502 is connected to the water outlet 404.

At this time, the gear seat 304B contacts and meshes with the gear ring 501A, and drives the filter disc 5 to move forward, so that the filter screen disc 503 contacts the fixed ring brush 110. At this time, the driving shaft 304 can drive the drum 4 to rotate through the filter disc 5. When the electric push rod 302 retracts the push rod, it drives the driving shaft 304 to move backward. At this time, the gear seat 304B is out of contact with the gear ring 501A, and the push ring 304C contacts the left side of the mounting disc frame 501 and pushes the filter disc 5 to move backward. At this time, the driving motor 301 drives the spiral blade 304A to rotate at a high speed. The spiral blade 304A draws wastewater from the connecting pipe 406 and introduces it into the left side of the filter screen disc 503 from the water outlet 404. After filtration, the wastewater moves to the right side of the filter screen disc 503, and the flocculated sediment is blocked by the filter screen disc 503.

[0057] like Fig.19As shown, a storage bin 2 is also provided on the outer wall of the tank body 1, and the storage bin 2 cooperates with the discharge notch 107. A slide groove 201 is fixedly provided on the storage bin 2, and the slide groove 201 is slidably connected with the slide bar 106. The installation of the storage bin 2 on the tank body 1 can be completed by aligning the slide groove 201 with the slide bar 106 and inserting it. The cleaned flocculated sediment enters the storage bin 2 from the discharge notch 107, and the flocculated sediment is collected.

[0058] The comprehensive treatment device for fermentation wastewater carries out a comprehensive treatment process for fermentation wastewater, comprising the following steps:

[0059] a: First, the fermentation wastewater and flocculant are put into the tank body 1, and ozone is introduced into the air inlet pipe 105, so that the driving motor 301 drives the drum 4 to rotate forward, and the fermentation wastewater and the flocculant are stirred and mixed. At the same time, the gas collecting shield 407 collects the ozone gas gathered on the top of the tank body 1 again and discharges it from the gas diffusion hole 405, so that the ozone can fully decompose the organic matter;

[0060] b: When one group of gas collecting shields 407 rotates to the bottom of the tank body 1, the electric push rod 302 is controlled to retract the push rod, and the drive motor 301 is adjusted to rotate in the opposite direction, so that the wastewater circulates and the flocculated sediment is blocked by the filter plate 503, thereby completing the cleaning operation of the flocculated sediment in the wastewater;

[0061] c: Control the electric push rod 302 to extend the push rod, adjust the drive motor 301 to rotate forward, the fixed ring brush 110 contacts the filter plate 503 and cleans the surface of the filter plate 503, and the flocculated sediment is collected in the storage bin 2, completing the collection and processing operation of the flocculated sediment.

[0062] Working principle:

[0063] 1. Fermentation wastewater and flocculant are put into the tank 1, and the liquid level is kept lower than the distance of one end of the top of the tank 1 to ensure that the floating unreacted ozone gas is collected at the top of the tank 1;

[0064] 2. Start the drive motor 301 and rotate it forward. The electric push rod 302 extends the push rod, driving the drive shaft 304 to move forward. The gear seat 304B pushes the mounting disc frame 501 forward. The rear part of the connecting rod 502 blocks the water outlet 404. At the same time, the gear seat 304B is engaged with the gear ring 501A. At this time, the power of the drive motor 301 is transmitted to the filter disc 5 through the drive shaft 304, and the filter disc 5 drives the drum 4 to rotate forward.

[0065] 3. As the drum 4 rotates continuously, the gas collecting shield 407 continuously stirs the wastewater to promote the mixing of the wastewater and the flocculant. At the same time, the gas collecting shield 407 presses down the ozone gas collected at the top of the tank body 1 again to allow the ozone gas to enter the connecting pipe 406;

[0066] 4. As the drum 4 rotates, when the top rod 602A contacts the first step 109A, the blocking ring 602 moves forward, the second blocking piece 602D opens the bottom connecting pipe 406, and the first blocking piece 602C closes the top connecting pipe 406. The plug body 702 moves backward under the push of the second compression spring 701, so that the inside of the drum 4 is in a negative pressure state. At this time, the ozone gas in the bottom connecting pipe 406 enters the inside of the drum 4 under the combined action of buoyancy and suction;

[0067] 5. The drum 4 continues to rotate, the top rod 602A contacts the second step 109B, the plugging piece 1 602C and the plugging piece 2 602D completely seal the connecting pipe 406, the limit top block 702B on the plug body 702 squeezes the top ear 108A, the plug body 702 moves forward, the inside of the drum 4 is in a high pressure state, the ozone gas is discharged from the diffuser hole 405, and reacts with the organic matter in the fermentation wastewater again. The ozone after the reaction turns into oxygen, which is lighter and is discharged from the outlet pipe 101. The ozone gas that has not reacted completely is collected at the bottom of the outlet pipe 101, waiting to be used again;

[0068] 6. When one of the connecting pipes 406 moves to the bottom of the tank body 1, the electric push rod 302 is controlled to retract the push rod, the drive shaft 304 moves backward, the push ring 304C pushes the mounting disc frame 501 backward, the connecting groove 502A is connected with the water port 404, and the driving motor 301 is controlled to rotate in the opposite direction. At this time, the power of the driving motor 301 is fully output to the spiral blade 304A, driving the spiral blade 304A to rotate at a high speed, and the wastewater is sucked into the inside of the drum 4 from the connecting pipe 406 at the bottom, and then flows into the left end of the filter disc 503 from the water port 404. After the flocculated sediment is blocked, the cleaned fermentation wastewater flows into the right side of the filter disc 503, and flows repeatedly to complete the cleaning operation, and the cleaned wastewater is discharged from the outlet pipe 103;

[0069] 7. Control the electric push rod 302 to extend the push rod again, and drive the motor 301 to rotate forward. At this time, the filter plate 503 contacts the fixed ring brush 110, and the fixed ring brush 110 cleans the surface of the filter plate 503. The flocculated sediment finally enters the storage bin 2 from the discharge slot 107, and the comprehensive treatment operation of the fermentation wastewater is completed.

[0070] The present invention sets a power mechanism 3. When the driving motor 301 drives the driving shaft 304 to rotate forward and controls the electric push rod 302 to extend, the drum 4 is driven to rotate to stir and aerate the wastewater. When the driving motor 301 rotates in the opposite direction and controls the electric push rod 302 to retract, the drum 4 stops rotating, the water inlet 404 is connected with the connecting groove 502A, and the wastewater is introduced to contact with the filter plate 503. The flocculated sediment therein is blocked by the filter plate 503 to complete the cleaning operation. By setting the drum 4, the wastewater can be stirred to promote the mixing of the wastewater and the flocculant. At the same time, the ozone gas floating to the top of the tank body 1 is collected and pressed down by the gas collecting shield 407. Under the combined action of its own buoyancy and suction, the ozone gas moves to the inside of the drum 4 through the connecting pipe 406 and is finally discharged from the diffuser hole 405, so that the unused ozone can contact with the wastewater for many times, thereby improving the utilization rate of the ozone.
