[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] Example 1, as Figure 1-2 As shown, a treatment device for epoxy resin production wastewater includes a base plate 1, a filtering mechanism 6 is fixedly connected to the right side of the upper end of the base plate 1, a sewage treatment mechanism 5 is fixedly connected to the left side of the filtering mechanism 6, the lower side of the sewage treatment mechanism 5 is fixedly connected to the middle part of the upper end of the base plate 1, the left side of the sewage treatment mechanism 5 is fixedly connected to the placement pool 4, the lower left side of the sewage treatment mechanism 5 is fixedly connected to the pumping component 2, the end of the pumping component 2 away from the sewage treatment mechanism 5 is fixedly connected to the front end of the placement pool 4, the left part of the upper front end of the base plate 1 is fixedly connected to the control cabinet 3, a plurality of dosing components 8 are provided on the front side of the upper end of the base plate 1, and a guard ladder frame 7 is fixedly connected to the front side of the upper end of the base plate 1.

[0020] It should be noted that the pumping component 2 is composed of two connecting pipes and a water pump, and the dosing component 8 is composed of a medicine barrel, a pipe, a connecting pipe and a small water pump. The medicine barrel is filled with relevant medicines for treating epoxy resin production wastewater. The specific installation methods of the water pump in the pumping component 2, the small water pump in the dosing component 8 and the control cabinet 3, as well as the circuit connection method and the control method are all conventional designs, which are conventional design means of designers. The control cabinet 3 is connected to an external power supply. The control cabinet 3 consists of a controller, a display, control buttons, an ozone generator, a connecting exhaust pipe, and an ozone concentration detector. All electrical equipment in the device can be controlled by the control cabinet 3, and ozone can be generated to deodorize the treated water in the placement tank 4. By adding a guard ladder frame 7, it is convenient for staff to observe the actual situation of wastewater treatment inside the device.

[0021] First, the epoxy resin production wastewater is discharged into the filtering mechanism 6, and the wastewater is pretreated by the filtering mechanism 6 to filter out larger impurities and floating oil in the wastewater. When the wastewater filtered in the filtering mechanism 6 reaches a certain amount, it begins to flow into the sewage treatment mechanism 5 to a predetermined value. An appropriate amount of reagent is added to the wastewater in the sewage treatment mechanism 5 through the dosing component 8. The operation of the sewage treatment mechanism 5 is controlled by the control cabinet 3 so that the wastewater and the reagent are fully mixed, and flotation treatment is performed so that the condensate generated in the wastewater combines with a large number of bubbles and floats upward to the liquid surface to form a foam layer, which is then discharged. The treated water is pumped into the placement tank 4 through the pumping component 2 and is deodorized and treated with deodorization in cooperation with the control cabinet 3, thereby completing the entire wastewater treatment work.

[0022] To achieve pre-treatment of wastewater, such as Figure 3 and Figure 4 As shown, the filtering mechanism 6 includes a sewage tank 61, a hollow heating plate 62 is fixedly connected to the bottom wall of the inner cavity of the sewage tank 61, a side plate 63 is fixedly connected to the upper left part of the inner cavity of the sewage tank 61, and a water outlet trough 64 is clamped on the left end of the side plate 63, a filtering group 65 is fixedly connected to the upper side of the inner cavity of the sewage tank 61, a water inlet pipe 66 is fixedly connected to the upper right side of the sewage tank 61, a sewage pipe 68 is fixedly connected to the upper left part of the rear end of the sewage tank 61, a sealing cover 67 is provided on the upper right part of the rear end of the sewage tank 61, and the lower end of the sewage tank 61 is fixedly connected to the upper right side of the bottom plate 1.

[0023] It should be noted that the specific installation method, circuit connection method and control method of the hollow heating plate 62 in the present invention are all conventional designs, which are conventional design means of designers. The hollow heating plate 62 is electrically connected to the control cabinet 3 through a wire, and the hollow heating plate 62 is composed of a hollow heating plate and a front-to-back symmetrical temperature detector to provide a suitable temperature for sewage treatment.

[0024] First, the epoxy resin production wastewater enters the right side of the filter group 65 through the water inlet pipe 66, and first removes larger impurities in the wastewater through the filter group 65, and then removes the floating oil in the wastewater after removing the larger impurities, and finally flows into the bottom of the inner cavity of the sewage pool 61. According to actual needs, it is decided whether to control the hollow heating plate 62 to heat the wastewater through the control cabinet 3. When the amount of wastewater entering the sewage pool 61 reaches the outlet trough 64, the wastewater will flow into the sewage treatment mechanism 5 through the outlet trough 64 until it reaches the preset value of the sewage treatment mechanism 5, and finally complete the pretreatment operation of the wastewater.

[0025] Further explanation, such as Figure 5 As shown, filter group 1 65 includes a floating plate 651, and the upper side of the outer surface of the floating plate 651 is slidingly connected to filter group 2 654, the upper end of the floating plate 651 is fixedly connected to a gate 653, and the front and rear sides of the outer surface of the gate 653 are slidingly connected to triangular guard plates 652, the upper ends of the two triangular guard plates 652 are fixedly connected to filter group 2 654, and the lower right side of the filter group 2 654 is fixedly connected to filter group 3 655.

[0026] In detail, the wastewater enters the right side of the filter group 2 654 through the water inlet pipe 66, and the larger impurities in the wastewater are filtered by the filter group 2 654. The filtered impurities enter the middle of the filter group 2 654 and are automatically discharged to the outside of the device through the sewage pipe 1 68 along the middle of the filter group 2 654. The wastewater with larger impurities removed then enters the filter group 3 655 through the right side of the filter group 2 654, and the floating oil in the wastewater is filtered by the filter group 3 655. The wastewater finally enters the inner cavity of the sewage pool 1 61. When the wastewater volume reaches the height of the outlet tank 64 and continues to rise, it is pushed by the buoyancy. The floating plate 651 drives the gate 653 to move upward between the inner cavities of the two triangular guard plates 652, so that the gate 653 no longer blocks the outlet trough 64, allowing the wastewater to enter the sewage treatment mechanism 5 through the inner cavity of the outlet trough 64. When the wastewater in the sewage treatment mechanism 5 reaches the preset value, the inner cavity of the sewage tank 61 will also retain pre-treated wastewater, so that it will not affect the further operation of the wastewater in the sewage treatment mechanism 5. After the sewage treatment mechanism 5 has processed the wastewater, the wastewater in the sewage tank 61 can directly enter the sewage treatment mechanism 5 for further treatment, saving time and improving work efficiency.

[0027] Further explanation, such as Figure 6 and Figure 7As shown, the second filter group 654 includes an irregular curved plate 6541, and the left side of the upper end of the irregular curved plate 6541 is fixedly connected to a front-to-back symmetrical auxiliary sleeve rod 6542, and the right side of the upper end of the irregular curved plate 6541 is provided with an arc-shaped filter shell 6543, and the inner cavity of the arc-shaped filter shell 6543 is rotatably connected to a semi-hollow rotor 6544, the outer surface of the irregular curved plate 6541 is fixedly connected to the upper side of the inner cavity of the sewage tank 1 61, the inner cavities of the two auxiliary sleeve rods 6542 are respectively slidably connected to the front and rear sides of the outer surface of the floating plate 651, and the upper ends of the two triangular guard plates 652 are fixedly connected to the left side of the lower end of the irregular curved plate 6541.

[0028] It should be noted that the hollow heating plate 62 can not only heat the wastewater when needed, but also appropriately reduce the amplitude of the water surface fluctuation when the wastewater enters the sewage pool 61. It is used in conjunction with the auxiliary sleeve 6542 to make the floating plate 651 slide up and down more stably under the action of buoyancy. The right side of the upper end of the irregular curved plate 6541 is higher than the left side, and the inclined surface in the middle of the irregular curved plate 6541 is higher than the rear side. It is connected to the inner cavity of the sewage pipe 68. When the wastewater passes through the water inlet pipe 66 to the half hollow wheel 6544 When the right side impacts, it will drive the semi-hollow impeller 6544 to rotate in the inner cavity of the arc-shaped filter shell 6543, and the wastewater will be filtered through the arc-shaped filter shell 6543 to filter out larger impurities. The filtered wastewater will enter the filter group three 655 through the bottom of the inner cavity of the arc-shaped filter shell 6543. The larger impurities filtered out are scraped from the bottom of the inner cavity of the arc-shaped filter shell 6543 to the inclined surface of the irregular curved plate 6541 under the rotation of the semi-hollow impurities, and are automatically discharged to the outside of the device through the sewage pipe 68.

[0029] In order to complete the operation of removing floating oil from wastewater, such as Figure 8 As shown, filter group three 655 includes a fixed frame 6551, a filter box 6553 is slidably connected to the lower side of the inner cavity of the fixed frame 6551, a hollow upper cover plate 6552 is provided on the upper end of the filter box 6553, a hollow plate 6554 is fixedly connected to the lower end of the filter box 6553, an oil detection component 6555 is fixedly connected to the lower end of the fixed frame 6551, and the upper end of the fixed frame 6551 is fixedly connected to the right side of the lower end of the irregular curved plate 6541.

[0030] It should be noted that the oil pollution detection component 6555 is composed of a diverter plate and an oil pollution detector. The specific installation method, circuit connection method and control method of the oil pollution detector are all conventional designs, which are conventional design methods of designers. The oil pollution detector is electrically connected to the control cabinet 3. In addition, activated carbon or attapulgite clay can be filled through the filter box 6553. Both activated carbon and attapulgite clay can be used as adsorbents to filter floating oil. After filling, it is covered with a hollow upper cover plate 6552.

[0031] After the wastewater passes through the bottom of the inner cavity of the arc-shaped filter shell 6543 and enters the hollow upper cover plate 6552, the wastewater enters the filter box 6553 through the hollow upper cover plate 6552, and the floating oil in the wastewater is adsorbed by the activated carbon or attapulgite clay in the filter box 6553, thereby achieving the purpose of filtering out the floating oil. After the floating oil is removed, the wastewater then flows through the hollow plate 6554 to the oil pollution detection component 6555, and the oil pollution detection component 6555 detects the floating oil content in the filtered wastewater and feeds back to the control cabinet 3. However, when it is detected that the floating oil content reaches a preset value, the activated carbon or attapulgite clay in the filter box 6553 needs to be replaced. At this time, the sealing cover 67 is opened, the filter box 6553 is pulled out of the inner cavity of the fixing frame 6551, and then the hollow upper cover plate 6552 is opened to replace the activated carbon or attapulgite clay in the filter box 6553 in time. After replacement, the filter box is put back in place, ultimately achieving the purpose of removing floating oil from the wastewater.

A J-shaped partition 54 is fixedly connected to the rear side of the bottom wall of the inner cavity of the sewage tank 2 51. The lower side of the inner cavity of the J-shaped partition 54 and the rear wall of the inner cavity of the sewage tank 2 51 are fixedly connected with a semicircular filter plate 541. The left side of the outer surface of the sewage discharge component 53 passes through the inner cavity of the sewage tank 2 51 and is respectively connected to the left rear part of the scraping component 52 and the output end of the driving component 1 55 through a belt. The middle of the front wall of the inner cavity of the sewage tank 2 51 is fixedly connected with an arc plate component 591, and the arc plate component 591 is located below a number of dosing pipes 593. A slag discharge groove 594 is opened on the right side of the bottom wall of the inner cavity of the J-shaped partition 54. A circulation component 595 is fixedly connected to the right side of the rear end of the pool 2 51, and the inner cavity of the slag discharge trough 594 is communicated with the circulation component 595. The output end of the circulation component 595 passes through the sewage pool 2 51 through a water pipe and is fixedly connected to the input end of the arc-shaped plate component 591. The lower end of the circulation component 595 is fixedly connected to the rear part of the upper end of the bottom plate 1, the lower end of the air pump 592 is fixedly connected to the front part of the upper end, the lower end of the sewage pool 2 51 is fixedly connected to the middle part of the upper end of the bottom plate 1, and the upper right part of the inner cavity of the sewage pool 2 51 is fixedly connected to the side plate 63.

[0033] It should be noted that the foam scraping component 52 is composed of two rotating shafts each equipped with a pulley and a foam scraping belt, and the pulleys in the two rotating shafts are connected by a belt, the sewage discharge component 53 is composed of an auger and a pulley, and is connected to the belt in the rotating shaft located at the rear side by a belt, the stirring component 59 is composed of a propeller stirring shaft and a pulley, and the two pulleys are connected by a belt, and the spiral directions of the propeller stirring shafts in the two stirring components 59 are opposite, the driving component 1 55 and the driving component 2 56 are both composed of a driving motor and a pulley, and the driving component 1 55 and the driving component 2 56 are connected by a belt.

The rear side of the outer surface of the arc plate component 591 is curved, and a water discharge hole is installed on the lower side of the curved surface, and the upper side of the outer surface of the arc plate component 591 is curved to match the scraping component 52.

[0034] When the sewage enters the space formed between the sewage tank 2 51 and the J-shaped partition 54 through the outlet trough 64 to an appropriate amount, the dosing component 8 is controlled by the control cabinet 3 to allow an appropriate amount of medicine to enter the wastewater through the dosing pipe 593. Then the control cabinet 3 controls the driving component 2 56 to drive the two stirring components 59 to rotate with the cooperation of the belt, and perform forward and reverse bidirectional stirring to make the wastewater and the medicine fully combined and quickly condense the suspended particles. Then the air pump 592 is started to generate gas to form a large number of bubbles through the air pipe and the aeration group 58 and evenly discharged from the bottom of the inner cavity of the sewage tank 2 51, so that the bubbles adhere to the suspended particles and float upward to form a foam layer. Then the driving component 1 55 is started to drive the scraping component 52 and the sewage discharge component 53 to operate simultaneously with the cooperation of the belt, and with the cooperation of the arc plate component 591, the foam layer can be maximized. The foam is scraped off by the scraping component 52 to the inner cavity of the semicircular filter plate 541, and the rotation of the sewage discharge component 53 drives the foam layer to be transported to the left in the inner cavity of the semicircular filter plate 541, and finally discharged from the sewage outlet connected to the leftmost side of the inner cavity of the semicircular filter plate 541, and the mixed water in the foam layer is filtered by the semicircular filter plate 541 to the bottom of the inner cavity of the J-shaped partition 54 and enters the circulation component 595 through the inner cavity of the slag discharge trough 594, and enters the bottom of the arc plate component 591 through the circulation component 595 and is discharged, so that the water flows back to the inner cavity of the sewage pool 2 51 for reprocessing, and while the water is sprayed out from the bottom of the arc plate component 591, the impurities that may be attached to the curved surface of the arc plate component 591 can also be cleared, and finally the further treatment of the wastewater is completed. After the wastewater treatment is completed, it is pumped into the placement pool 4 by the pumping pipe 57 by the pumping component 2, ready for the next deodorization operation.

[0035] Further explanation, such as Figure 11 As shown, several aeration groups 58 all include branch pipes 581, the upper ends of several branch pipes 581 are fixedly connected to conical air disks 582, the outer surfaces of several conical air disks 582 are fixedly connected to several exhaust heads 583, and several branch pipes 581 are fixedly connected to the output end of the air pump 592 through the air pipe.

[0036] In detail, when the air pump 592 is started, air is generated and enters the inner cavity of the branch pipe 581 through the air pipe, enters the conical air disk 582 through the inner cavity of the branch pipe 581, and is finally discharged to the bottom of the inner cavity of the sewage pool 2 51 through a number of exhaust heads 583, and is discharged downward through the exhaust heads 583. Not only does it make the exhaust heads 583 less likely to be blocked by suspended particles, but the bubbles generated can also maximize the attachment and upward floating of suspended particles at the bottom of the inner cavity of the sewage pool 2 51, making the wastewater treatment more thorough.
