Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The purpose of this invention is to provide a microbial reaction device to solve the problems existing in the prior art, reduce the entry of fibrous impurities into the reactor, and improve the working efficiency of the reactor.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This invention provides a microbial reaction device, such as... Figures 1-7As shown, the device includes a fluid conveying device 1, an anaerobic reactor 2, and an aerobic reactor 3 connected in sequence. The anaerobic reactor 2 can perform an anaerobic reaction on the dyeing and printing wastewater, and the aerobic reactor 3 can perform an aerobic reaction on the dyeing and printing wastewater discharged from the anaerobic reactor 2. A first inlet 21 is provided at the bottom of the anaerobic reactor 2 to receive the dyeing and printing wastewater conveyed by the fluid conveying device 1. A filter screen 23 is provided in the anaerobic reactor 2 near the first inlet 21. The filter screen 23 can filter out fiber impurities in the dyeing and printing wastewater, reducing the amount of fiber impurities entering the anaerobic reactor 2 or the aerobic reactor 3 and causing blockage, thereby improving the working efficiency of the anaerobic reactor 2 or the aerobic reactor 3.

[0033] In some embodiments of this utility model, such as Figures 1-2 As shown, a first outlet 22 is provided on the side wall of the anaerobic reactor 2 near the top of the anaerobic reactor 2 for discharging dyeing and printing wastewater. Microbial carrier packing is provided on the side of the filter screen 23 near the first outlet 22. A perforated first partition 24 is also provided inside the anaerobic reactor 2. The first partition 24 is located on top of the microbial carrier packing inside the anaerobic reactor 2. The first partition 24 is closer to the filter screen 23 than the first outlet 22 and can move up and down with the volume change of the microbial carrier packing. At least two first baffles 25 are also provided on the side wall of the anaerobic reactor 2. The first baffles 25 are located between the first outlet 22 and the first partition 24. The first baffles 25 can abut against the first partition 24. As the wastewater in the anaerobic reactor 2 increases, the microbial carrier packing will gradually float up or absorb water and expand. The first partition 24 moves upward with the microbial carrier packing until the first baffles 25 abut against the first partition 24, so that the first partition 24 can press down the microbial carrier packing and prevent the microbial carrier packing from exceeding the first outlet 22 and causing the first outlet 22 to be blocked.

[0034] In some embodiments of this utility model, the microbial carrier packing material can be selected from polyurethane sponge packing material or polypropylene suspension balls. The amount of packing material added is 50%-60% of the total volume. The polyurethane in the polyurethane sponge packing material has many pores and a large specific surface area, which is suitable for the attachment and growth of microorganisms. It can allow wastewater and microorganisms to fully contact each other. In addition, polyurethane has good elasticity and high mechanical strength, and is not easily dispersed or damaged by water flow. It is suitable for use in dynamic water treatment environments. Polypropylene is a common plastic with good chemical stability and resistance to acid and alkali corrosion. The design of the suspension balls allows them to suspend freely in water to increase the contact area with wastewater and avoid the clogging problem caused by packing material accumulation. Moreover, the surface structure of the suspension balls has many protrusions or ripples, which can increase the specific surface area and facilitate the attachment of organisms.

[0035] In some embodiments of this utility model, such as Figure 5As shown, the first partition 24 consists of two semi-circular perforated plates connected by a hinge. Each of the two semi-circular perforated plates has two handles. The operator can fold the first partition 24 through the two handles to remove the first partition 24 from the anaerobic reactor 2 for replacement of the microbial carrier packing or the filter screen 23.

[0036] In some embodiments of this utility model, such as Figures 1-2 As shown, the number of first baffles 25 is 2 to 4, preferably 3. The shape of the first baffles 25 is wedge-shaped or small cuboid. The three first baffles 25 are evenly arranged along the inner sidewall of the anaerobic reactor 2, which can fully abut the edge of the first partition 24 and also avoid affecting the removal of the first partition 24 from the anaerobic reactor 2.

[0037] In some embodiments of this utility model, such as Figures 1-2 As shown, the top of the anaerobic reactor 2 is equipped with an openable first cover 26. By opening the first cover 26, the operator can replace the microbial carrier packing or the filter screen 23. The operator can also manually skim off the oil to improve the water quality after treatment by the microbial reactor.

[0038] In some embodiments of this utility model, an oil skimmer is also provided in the anaerobic reactor 2 between the first baffle 25 and the first outlet 22. The oil skimmer can remove the floating oil on the surface of the dyeing and printing wastewater in the anaerobic reactor 2, thereby improving the water quality after treatment by the microbial reaction device.

[0039] Specifically, the oil skimmer is a belt skimmer, which uses a transmission belt to collect floating oil on the water surface. The transmission belt moves the oil spilled on the water surface and adheres to it. Then, the oil is guided into the oil collection tank by the scraper, thus removing the floating oil on the surface of the dyeing wastewater in the anaerobic reactor 2, thereby improving the water quality after treatment by the microbial reaction device.

[0040] In some embodiments of this utility model, such as Figures 1-2 As shown, the aerobic reactor 3 is provided with a second inlet 31 at the bottom, which can receive the dyeing and printing wastewater discharged from the anaerobic reactor 2. An aeration disc 33 is provided in the aerobic reactor 3 near the second inlet 31. The air outlet of the aeration disc 33 faces the side away from the second inlet 31. The aeration disc 33 can provide oxygen into the aerobic reactor 3. The aeration disc 33 is located at the bottom, and the air bubbles float upward from the bottom of the aerobic reactor 3, experiencing the longest liquid phase contact path, which can prolong the residence time of oxygen in the dyeing and printing wastewater in the aerobic reactor 3.

[0041] In some embodiments of this utility model, such as Figure 4As shown, an aeration pipe 34 is also provided on the side of the aeration disc 33 away from the second inlet 31. The air outlets of the aeration pipe 34 are evenly distributed along the circumference of the aeration pipe 34. When the oxygen supply of the aeration disc 33 is insufficient, the aeration pipe 34 provided between the aeration disc 33 and the second inlet 31 is activated to provide more oxygen to the surrounding microorganisms.

[0042] In some embodiments of this utility model, such as Figures 1-2 As shown, a second outlet 32 ​​is provided on the side wall of the aerobic reactor 3 near the top of the aerobic reactor 3 for discharging dyeing and printing wastewater. Microbial carrier packing is provided on the side of the aeration disc 33 near the second outlet 32. A perforated second baffle 35 is also provided inside the aerobic reactor 3. The second baffle 35 is located on top of the microbial carrier packing inside the aerobic reactor 3 and is closer to the aeration disc 33 than the second outlet 32. It can move up and down with the volume change of the microbial carrier packing. At least two second baffles 36 are also provided on the side wall of the aerobic reactor 3. The second baffles 36 are located between the second outlet 32 ​​and the second baffle 35. The second baffles 36 can abut against the second baffle 35. As the wastewater in the aerobic reactor 3 increases, the microbial carrier packing will gradually float up or absorb water and expand. The second baffle 35 moves upward with the microbial carrier packing until the second baffles 36 abut against the second baffle 35, so that the second baffle 35 can press down the microbial carrier packing and prevent the microbial carrier packing from exceeding the second outlet 32 ​​and causing blockage of the second outlet 32.

[0043] In some embodiments of this utility model, such as Figures 1-2 As shown, the end of the anaerobic reactor 2 near the first inlet 21 has a conical structure. The conical structure can support the filter screen 23, thereby providing a distance between the first inlet 21 and the filter screen 23. This avoids the fiber impurities from being concentrated and intercepted in a small part of the filter screen when the filter screen is very close to the first inlet, thus making full use of the entire area of ​​the filter screen 23 to filter the fiber impurities.

[0044] In some embodiments of this utility model, such as Figure 5 As shown, the second partition 35 consists of two semi-circular perforated plates connected by a hinge. Each of the two semi-circular perforated plates has two handles. The operator can fold the second partition 35 through the two handles to remove the second partition 35 from the aerobic reactor 3 for replacing the microbial carrier packing or repairing the aeration disc 33 or aeration pipe 34.

[0045] In some embodiments of this utility model, such as Figures 1-2As shown, the number of second baffles 36 is 2 to 4, preferably 3. The shape of the second baffles 36 is wedge-shaped or small cuboid. The three second baffles 36 are evenly arranged along the inner sidewall of the aerobic reactor 3, which can fully abut the edge of the second partition 35 and also avoid affecting the removal of the second partition 35 from the aerobic reactor 3.

[0046] In some embodiments of this utility model, such as Figures 1-2 As shown, the top of the aerobic reactor 3 is equipped with a second cover 37 that can be opened. By opening the second cover 37, the operator can replace the microbial carrier packing.

[0047] In some embodiments of this utility model, such as Figures 1-2 As shown, the air inlet of the aeration disc 33 and the air inlet of the aeration pipe 34 are both connected to the aeration pump 332 located outside the aerobic reactor 3 via pipelines. Flow meters 331 are installed on the pipelines connecting the aeration disc 33 and the aeration pipe 34 to the aeration pump 332 to measure the volume of gas introduced.

[0048] In some embodiments of this utility model, such as Figures 1-2 As shown, the anaerobic reactor 2 is set on the first support 4, and the aerobic reactor 3 is set on the second support 5. The height of the second support 5 is less than the height of the first support 4, so that the dyeing wastewater in the anaerobic reactor 2 can flow into the aerobic reactor 3 by its own gravity.

[0049] In some embodiments of this utility model, the fluid conveying device 1 is a peristaltic pump. One end of the peristaltic pump is connected to the wastewater pool, and the other end is connected to the first inlet 21. The peristaltic pump can accurately control the flow rate of the dyeing and printing wastewater entering the anaerobic reactor 2 according to the chemical oxygen demand (COD) concentration of the dyeing and printing wastewater, so as to prevent excessive dyeing and printing wastewater from entering the anaerobic reactor 2.

[0050] In some embodiments of this utility model, the peristaltic pump is also connected to the clear water tank. The peristaltic pump can introduce a portion of clear water to mix with the dyeing and printing wastewater when the COD concentration is too high, and then introduce them into the anaerobic reactor 2 together to prevent excessive dyeing and printing wastewater from entering the anaerobic reactor 2.

[0051] In some embodiments of this utility model, such as Figures 1-2As shown, a first water level alarm 27 is installed between the first outlet 22 and the top of the anaerobic reactor 2, and a second water level alarm 38 is installed between the second outlet 32 ​​and the top of the aerobic reactor 3. A first pH meter 28 is installed between the first outlet 22 and the first baffle 25, and a dissolved oxygen meter 371 and a second pH meter 39 are installed between the second outlet 32 ​​and the second baffle 36. By installing the water level alarm, the operator is notified in time when there is too much dyeing wastewater in the anaerobic reactor 2 or the aerobic reactor 3 to prevent the dyeing wastewater from overflowing. The dissolved oxygen meter 371 allows the operator to understand the dissolved oxygen concentration in the dyeing wastewater in the aerobic reactor 3 and judge the living environment of the microorganisms. The pH meter allows the operator to maintain the dyeing wastewater at a suitable pH value, give full play to the activity of microorganisms, and improve the working efficiency of the anaerobic reactor 2 and the aerobic reactor 3.

[0052] In some embodiments of this utility model, such as Figure 7 As shown, the microbial reactor also includes a controller 6. The controller 6 is connected to the first water level alarm 27, the second water level alarm 38, the first pH meter 28, the second pH meter 39, and the dissolved oxygen meter 371. The controller 6 is also connected to a display screen, which can display the pH value in the anaerobic reactor 2 and the dissolved oxygen concentration and pH value in the aerobic reactor 3. When the water level in any reactor is too high, the display screen can issue an alarm in time.

[0053] In some embodiments of this utility model, the aeration rate of the aeration disc and aeration pipe 34 is controlled based on the dissolved oxygen concentration monitored by the dissolved oxygen detector 371.

[0054] In some embodiments of this utility model, such as Figures 1-2 As shown, observation windows 7 are provided on the side walls of both anaerobic reactor 2 and aerobic reactor 3 to allow operators to visually observe and understand the operation of the reactors and the thickness of the oil layer, and to promptly handle any malfunctions during equipment operation.

[0055] In some embodiments of this utility model, such as Figures 1-2 As shown, valves 8 are installed on the pipeline from the peristaltic pump to the first inlet 21 of the anaerobic reactor 2, the pipeline from the first outlet 22 of the anaerobic reactor 2 to the second inlet 31 of the aerobic reactor 3, and the pipeline connected to the second outlet 32 ​​of the aerobic reactor 3, so as to facilitate the operation of the personnel.

[0056] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
