Description

Technical Field

[0001] This invention belongs to the technical field of wastewater treatment equipment, specifically a wastewater treatment device for biopharmaceutical production. Background Technology

[0002] Biopharmaceutical production wastewater refers to wastewater generated during the research and development and production of biopharmaceuticals. It is characterized by complex composition, high organic matter concentration, high toxicity, and poor biodegradability. Therefore, the treatment of biopharmaceutical production wastewater is crucial, requiring appropriate wastewater treatment equipment and methods. Examples include LSP (Lawsludge Reduction) biological treatment technology and wastewater treatment equipment using this technology. Through specific process design and operation, this biological treatment technology achieves sludge reduction at the source, minimizing solid waste (sludge). The treatment process of this wastewater treatment equipment includes physical pretreatment → anaerobic digestion → aerobic aeration → membrane bioreactor (MBR) → reverse osmosis → reuse.

[0003] In some existing wastewater treatment equipment, during the aerobic aeration stage, the aeration heads may be clogged by sludge and impurities, resulting in uneven aeration and localized hypoxia. Localized hypoxia may prevent microorganisms from fully oxidizing and decomposing organic matter in the wastewater, reducing the treatment effect. Furthermore, in the process of preventing clogging of the aeration heads, sludge may accumulate inside the aeration heads, which is not easy to remove in time and affects the gas flow.

Detailed Implementation

[0043] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see Figure 1 - Figure 7 This application provides a wastewater treatment device for biopharmaceutical production, comprising:

[0046] Wastewater treatment tank 100 has an aerobic chamber 103, a sedimentation chamber 104, a reaction chamber 105 and an operating chamber 106 arranged from right to left inside the wastewater treatment tank 100. A high-pressure blower for aeration of the aerobic chamber 103 is installed in the operating chamber 106. Multiple inspection doors 102 are opened on the top of the wastewater treatment tank 100, and each inspection door 102 corresponds to each chamber, which facilitates the inspection or operation of each chamber. A sewage pipe 101 that communicates with each chamber is provided on the front surface of the wastewater treatment tank 100.

[0047] An aeration structure is installed inside the aerobic chamber 103. The aeration structure is distributed at the bottom of the aerobic chamber 103, with a large distribution area, which facilitates sufficient aeration of the wastewater inside the aerobic chamber 103. The aeration structure includes an aeration head 600 for aeration inside the aerobic chamber 103 and an anti-clogging and decontamination structure 200 installed at the bottom of the aeration head 600 to prevent clogging. The anti-clogging and decontamination structure 200 can continuously unclog the aeration holes 601 on the surface of the aeration head 600 during the aeration process, preventing sludge from clogging the aeration holes 601 and causing local hypoxia. This ensures sufficient and uniform oxygen, improves the treatment effect of biopharmaceutical wastewater, and can also suck up the sludge that is still stuck in the aeration head 600, preventing it from accumulating in the aeration head 600 and increasing the smoothness of gas aeration.

[0048] The anti-clogging and decontamination structure 200 includes an anti-clogging component 203 that prevents clogging of multiple aeration holes 601 on the upper surface of the aeration head 600, a connecting cylinder 202 installed at the bottom of the aeration head 600, and a decontamination component 204 that treats the sludge after clogging. The aeration holes 601 are evenly distributed on the upper surface of the aeration head 600, and the aeration head 600 is funnel-shaped and hollow inside to facilitate the passage of gas.

[0049] The anti-clogging component 203 includes a guide ring 2031 that is horizontally located inside the aeration head 600 and can be raised and lowered. The guide ring 2031 cooperates with the central disc 2035 to support and fix the stabilizing rods 2032. There is enough space between the multiple stabilizing rods 2032 to ensure that the gas flow is not affected. Multiple stabilizing rods 2032 are arranged around the inner circumference of the guide ring 2031. The upper surface of the stabilizing rods 2032 is provided with an anti-clogging rod 2033 that clears the aeration holes 601. The anti-clogging rod 2033 is a tapered rod with its upper tip located in the aeration hole 601. It can move up and down in the aeration hole 601 as the guide ring 2031 rises and falls to clear the blockage and prevent sludge from clogging the aeration hole 601.

[0050] The cleaning component 204 includes a suction cylinder 2041 that is inclined outside the connecting cylinder 202. The left end of the suction cylinder 2041 is lower than the right end, which facilitates the flow of objects inside the suction cylinder 2041 to the left. The inner end of the suction cylinder 2041 is provided with a suction pipe 2043 that extends into the connecting cylinder 202. The suction pipe 2043 is L-shaped, which facilitates the right end of the suction pipe 2043 to extend to the outer surface of the guide cover 207. The suction cylinder 2041 is provided with a movable piston block 2044. As the piston block 2044 moves, the internal space of the suction cylinder 2041 changes, which facilitates the suction of sludge.

[0051] In this embodiment, preferably, the anti-clogging component 203 for unblocking the aeration holes 601 further includes:

[0052] A central disk 2035 is located at the inner end of multiple stabilizing rods 2032. A support rod 2034 extending into the interior of the connecting cylinder 202 is provided on the lower surface of the central disk 2035. The diameter of the support rod 2034 is smaller than the diameter of the lower end of the connecting cylinder 202 and the aeration head 600, so that there is space between the support rod 2034 and the inner wall of the connecting cylinder 202 to facilitate the passage of gas.

[0053] A stabilizing plate 20311 is fixed to the inner wall of the connecting cylinder 202. A rotatable cylindrical cam 2036 is embedded inside the stabilizing plate 20311. A bearing is embedded between the stabilizing plate 20311 and the cylindrical cam 2036. A guide groove 2038 is provided on the surface of the cylindrical cam 2036. A lifting slide rod 20310 that drives the support rod 2034 to move up and down is slidably arranged in the guide groove 2038.

[0054] During aeration, the fan blade 2037 installed at the bottom of the cylindrical cam 2036 is impacted by the upward flow of gas. The arc shape of the fan blade 2037 rotates under the wind force, thereby driving the cylindrical cam 2036 to rotate.

[0055] In this embodiment, preferably, a guide slider 2039 is slidably disposed inside the guide groove 2038, and the lifting rod 20310 cooperates with the stabilizing plate 20311 to prevent lateral displacement, so that the guide slider 2039 will not detach from the guide groove 2038. The lower end of the lifting rod 20310 is connected to the guide slider 2039, and the upper end of the lifting rod 20310 moves through the stabilizing plate 20311 and is fixed to the support rod 2034. The lower end of the support rod 2034 moves into the cylindrical groove opened at the center of the cylindrical cam 2036. The cooperation between the support rod 2034 and the cylindrical groove can both guide and support the up and down movement of the support rod 2034, and does not affect the rotation of the cylindrical cam 2036.

[0056] In summary, during operation, the high-pressure blower operates, introducing gas into the aeration pipe 300 and then sending it from the aeration branch pipe 400 into the connecting cylinder 202. The upward-flowing gas acts on the fan blade 2037, causing it to rotate and drive the cylindrical cam 2036 to rotate. The guide groove 2038 on the cylindrical cam 2036 rotates, and the guide slider 2039, which cooperates with the guide groove 2038, moves within the groove. The lifting rod 20310 connected to the guide slider 2039 and the stabilizing plate 20311 limit the movement, ensuring that the lifting rod 20310 and the guide slider 2039 cooperate to guide the movement. The trough 2038 can only move up and down, thereby driving the support rod 2034 connected to the lifting slide bar 20310 to move up or down, which in turn drives the central disc 2035, the stabilizing rod 2032, and the guide ring 2031 to move. The anti-clogging rod 2033 moves up or down in the aeration hole 601, continuously clearing the aeration hole 601. During the clearing process, the anti-clogging rod 2033 is always kept at a distance from the inner wall of the aeration hole 601, so as not to affect the gas flow and at the same time, it will not allow sludge to clog the aeration hole 601, and there will be no local hypoxia. This can fully improve the oxidation treatment effect of organic matter in wastewater.

[0057] Example 2

[0058] Reference Figure 4 and Figure 8 This is the second embodiment of the present invention.

[0059] In this embodiment, preferably, a guide cover 207 is provided inside the connecting cylinder 202, located below the fan blade 2037. The guide cover 207 is a hollow frustum shape, with the upper diameter smaller than the lower diameter, which facilitates the guiding and gathering of gas flowing upward from below. The gathered gas acts on the fan blade 2037. A waterproof sleeve 208 is fitted on the upper end of the guide cover 207. The waterproof sleeve 208 can be a PTFE composite waterproof cloth sleeve. When impacted by gas flowing upward from below, the waterproof sleeve 208 expands under the gas impact, forming a shape similar to a frustum, and the gas flows out from the waterproof sleeve 207. The air vent at the top of 08 acts on the fan blade 2037. During non-aeration, there is no gas impact expansion. Due to gravity, the anti-seepage sleeve 208 falls irregularly onto the guide cover 207. As the anti-seepage sleeve 208 falls, its upper air vent folds down and covers the upper hole of the guide cover 207. Even without the upward impact force of gas, the guide cover 207, together with the anti-seepage sleeve 208 and the connecting cylinder 202, intercepts sludge or water, preventing sludge and water from entering the aeration pipe 300, reducing cleaning trouble, and not affecting the subsequent gas aeration flow.

[0060] In this embodiment, preferably, the sludge removal component 204 for treating the sludge collected inside the connecting cylinder 202 further includes:

[0061] A discharge port 2045 is opened on the lower left end of the suction cylinder 2041. The discharge port 2045 is located to the left of the piston block 2044. An exhaust pipe 2042 is provided on the upper right end of the suction cylinder 2041. A gas one-way valve can be provided on the exhaust pipe 2042. The function of the gas one-way valve is to prevent external gas from entering the interior of the suction cylinder 2041 through the exhaust pipe 2042, but it does not affect the gas inside the suction cylinder 2041 from being discharged to the outside through the exhaust pipe 2042. The gas one-way valve is prior art and will not be explained in detail in this application.

[0062] A piston rod 2046 is fixed to the left side of the piston block 2044. The left end of the piston rod 2046 passes through the suction cylinder 2041 and protrudes to the outside. A pull ring is provided at the left end of the piston rod 2046, which can pull the piston rod 2046 and the piston block 2044 to move.

[0063] In this embodiment, preferably, the aeration structure further includes an aeration pipe 300 distributed at the bottom of the aerobic chamber 103. An aeration branch pipe 400 is vertically arranged on the upper surface of the aeration pipe 300. A pretreatment cylinder 201 is arranged between the aeration branch pipe 400 and the connecting cylinder 202. The pretreatment cylinder 201 and the connecting cylinder 202 are connected internally to facilitate gas flow. A support seat 2048 for supporting the suction cylinder 2041 is arranged on the upper surface of the pretreatment cylinder 201. A collection box 2047 located below the discharge port 2045 is arranged between the two support seats 2048 to facilitate sludge collection and treatment. The collection box 2047 can be disassembled and removed.

[0064] In summary, without aeration, the wastewater and sludge in the aerobic chamber 103 are retained at the connecting cylinder 202 and guide cover 207 through the aeration holes 601. At this time, the anti-seepage sleeve 208 is folded and covers the upper end of the guide cover 207, making it difficult for sludge to enter the pretreatment cylinder 201 and the aeration pipe 300. Furthermore, the guide cover 207 is frustoconical in shape, facilitating the accumulation of sludge between the lower end of the guide cover 207 and the connecting cylinder 202, located below the right end of the suction pipe 2043. By pulling the pull ring, the piston rod 2046 moves to the left, causing the piston block 2044 to move to the left. The space inside the suction cylinder 2041 gradually increases, drawing the sludge accumulated between the outer surface of the guide cover 207 and the inner wall of the connecting cylinder 202 into the suction cylinder 2041 through the suction pipe 2043. When the piston block 2044 moves to the discharge port 2045, the piston block 2044 exposes the discharge port 2045, allowing... The sludge is discharged from the discharge port 2045 along the inner wall of the inclined suction cylinder 2041 and falls into the collection box 2047. During the movement of the piston block 2044, no external gas is drawn from the exhaust pipe 2042, which facilitates better suction of the sludge in the connecting cylinder 202. After the sludge in the suction cylinder 2041 is discharged, the piston rod 2046 is pushed to the right, which drives the piston block 2044 to move to the right to re-seal the discharge port 2045. As the piston block 2044 continues to move to the right, the space on the right side of the piston block 2044 gradually becomes smaller, and the air in the right space is discharged through the exhaust pipe 2042. The whole process increases the convenience of sludge treatment inside the connecting cylinder 202, and prevents sludge from entering the aeration pipe 300, reducing the trouble of cleaning sludge, and does not affect the gas flow and aeration, which facilitates the full entry of gas into the aerobic chamber 103 to oxidize the organic matter in the wastewater.

[0065] In this embodiment, preferably, as an alternative to the present application, the suction cylinder 2041 can be replaced with a pump pipe connected to the suction pipe 2043, and multiple pump pipes are connected internally. The connected pump pipes are connected to a suction pump located on the outer surface of the wastewater treatment tank 100. The suction pressure generated by the suction pump is used to simultaneously suction the sludge in the connecting cylinder 202 and transport the suction sludge to a sludge tank located on the outside of the wastewater treatment tank 100. The suction pump, pump pipe and sludge tank are not shown in the present application. As another technical solution to replace the suction cylinder 2041 in the present application, it can be selected according to actual production needs and usage environment.

[0066] Example 3

[0067] Reference Figure 4 , Figure 9 and Figure 10 This is the third embodiment of the present invention.

[0068] In this embodiment, preferably, by providing the processing component 205, the aeration gas entering the aerobic chamber 103 can be pretreated. The gas is first heated or cooled selectively, so that the temperature-controlled gas enters the aerobic chamber 103. The uniformly distributed gas can effectively regulate the temperature of the wastewater in the aerobic chamber 103. Compared to temperature regulation on the side or bottom of the wastewater treatment tank 100, this gas-based temperature regulation is more uniform, allowing the aerobic chamber 103 to maintain a suitable temperature for treating organic matter in biopharmaceutical wastewater. The processing component 205, installed inside the pretreatment cylinder 201 and used to regulate the temperature of the passing gas, includes:

[0069] A cooling component 2053 is vertically located at the center of the pretreatment cylinder 201. The cooling component 2053 divides the interior of the pretreatment cylinder 201 into a first cavity 2051 and a second cavity 2052. The first cavity 2051 and the second cavity 2052 can be used alternately.

[0070] A micro motor 2056 is vertically installed inside the connecting cylinder 202, and an air inlet 206 is left between the pretreatment cylinder 201 and the aeration branch pipe 400.

[0071] The lower semicircular plate 2054 installed at the bottom of the cooling component 2053 and located in the air inlet 206, and the upper semicircular plate 2055 located on the upper surface of the cooling component 2053 and close to the upper end of the pretreatment cylinder 201, the upper semicircular plate 2055 is half the diameter of the pretreatment cylinder 201, and works with the cooling component 2053 to seal half of the space of the pretreatment cylinder 201, the lower semicircular plate 2054 is half of the air inlet 206.

[0072] In this embodiment, preferably, the micro motor 2056 is provided with a connecting shaft 2058 at its bottom. The connecting shaft 2058 passes through the cooling component 2053 and is connected to the upper semicircular plate 2054 and the lower semicircular plate 2055, which can drive the upper semicircular plate 2054 and the lower semicircular plate 2055 to rotate synchronously. The micro motor 2056 is covered with a waterproof shell 2057 to protect it. The waterproof shell 2057 is fixed to the inner wall of the connecting cylinder 202, and there is enough space between them for gas to pass through.

[0073] In this embodiment, preferably, the cooling component 2053 includes a protective shell 20531 installed between the lower semicircular plate 2054 and the upper semicircular plate 2055. A cooling plate 20533 is disposed inside the protective shell 20531. The protective shell 20531 can be a metal shell with a high thermal conductivity coefficient to facilitate heat conduction. An energy storage box 20532 is disposed inside the protective shell 20531 and installed on the top of the cooling plate 20533. The energy storage box 20532 supplies energy to the cooling plate 20533. The cooling plate 20533 is a semiconductor plate. When the cooling plate 20533 is working, one side absorbs heat and cools, and the other side releases heat. It works in conjunction with the first cavity 2051 and the second cavity 2052 so that one cavity cools the incoming gas and the other heats the incoming gas.

[0074] In this embodiment, preferably, the upper surface of the left end of the aeration pipe 300 is provided with a connecting pipe 500 that connects to the high-pressure blower inside the control chamber 106, so as to facilitate aeration of the aerobic chamber 103.

[0075] In summary, if the first chamber 2051 is configured to heat the gas, and the second chamber 2052 to cool the gas, then the first chamber 2051 corresponds to the heat dissipation surface of the cooling plate 20533, while the second chamber 2052 corresponds to the heat absorption and cooling surface of the cooling plate 20533. If gas cooling is required, the micro motor 2056 can be activated to rotate the connecting shaft 2058 and the lower semicircular plate 2054 and upper semicircular plate 2055 connected to the connecting shaft 2058 by 180 degrees, exposing the air inlet 206 and the right half of the pretreatment cylinder 201. The air inlet 206 and the left half of the pretreatment cylinder 201 are blocked, thereby blocking the first chamber 2051. This allows the aeration branch pipe 400 to communicate with the interior of the second chamber 2052, and the second chamber 2052 to communicate with the interior of the connecting cylinder 202. When the high-pressure blower supplies air, the gas enters the second chamber 2052 through the aeration pipe 300 and the aeration branch pipe 400. The cooling plate 20533 operates, and the heat-absorbing cooling surface conducts the temperature to the right side of the protective shell 20531. The gas entering the second chamber 2052 will interact with the right side of the protective shell 20531. Side contact cools the gas, which then flows upwards and exits through aeration holes 601, directly acting on the wastewater in the aerobic chamber 103. The cooled gas impacts the wastewater flow and its own heat further cools the wastewater, causing it to cool down rapidly and evenly to the temperature required for organic oxidation. Conversely, if it is necessary to heat the wastewater in the aerobic chamber 103, the micro motor 2056 drives the upper semicircular plate 2055 and the lower semicircular plate 2054 to rotate 180 degrees, thus affecting the second... Cavity 2052 is sealed, while the first cavity 2051 is connected to the connecting cylinder 202 and the aeration branch pipe 400. The heat dissipation surface of the cooling plate 20533 conducts the temperature to the left side of the protective shell 20531. The gas enters the first cavity 2051 and contacts the left side of the protective shell 20531, heating the gas so that it is finally discharged from the aeration hole 601 and enters the aerobic chamber 103, which plays a role in uniformly heating the wastewater in the aerobic chamber 103, keeping the wastewater within a suitable temperature range, and increasing the oxidation treatment effect on organic matter in the wastewater.

[0076] Example 4

[0077] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0078] In use, the biopharmaceutical production wastewater undergoes pretreatment such as bar filtration before entering the aerobic chamber 103, which is known prior art and will not be described in detail in this application. After pretreatment, the wastewater enters the aerobic chamber 103, where oxygen is introduced to oxidize the organic matter. During oxygen introduction, the aeration holes 601 are continuously cleared using the anti-clogging component 203, preventing blockage and oxygen deficiency. Simultaneously, the sludge retained in the connecting cylinder 202 is suctioned out using the sludge removal component 204, without affecting gas flow or preventing sludge backflow into the aeration pipe 300. During aeration, the gas is temperature-controlled. Temperature control is achieved by allowing gas to be introduced into the aerobic chamber 103 to maintain the temperature range for treating organic matter in the wastewater, ensuring more uniform temperature control. The wastewater treated in the aerobic chamber 103 is then introduced into the sedimentation chamber 104 for sedimentation treatment, and the settled sludge is discharged. The liquid is then introduced into the reaction chamber 105, where appropriate reaction treatment agents are added. These reaction treatment agents are oxidants or reducing agents for treating harmful substances in the wastewater. The specific agents need to be added according to the composition of the wastewater. The treated wastewater is then transported to other external treatment equipment for testing and further treatment. This treatment process is existing technology, and the detailed retreatment process will not be described in detail.

[0079] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
