Description

Technical Field

[0001] This utility model belongs to the field of biological wastewater treatment technology, specifically an inactivation system for biologically active toxic wastewater. Background Technology

[0002] Biologically active wastewater contains a large number of active pathogens, such as viruses, bacteria, and fungi. Improper treatment and direct discharge can cause serious pollution to the ecological environment and even endanger human health. Therefore, efficient inactivation treatment of biologically active wastewater is an indispensable step in fields such as biopharmaceuticals, medical and health care, and biological research.

[0003] Currently, the inactivation treatment of biologically active wastewater mostly employs thermal inactivation methods. The core principle is to destroy the protein structure of pathogens through high temperatures, rendering them inactive. Existing technologies typically include wastewater delivery pipelines, steam supply devices, reaction vessels, and simple control components. For example, some systems directly introduce steam into the reaction tank containing the biologically active wastewater, utilizing the high temperature of the steam to achieve inactivation, while simultaneously using a stirring device to agitate the wastewater and promote mixing.

[0004] However, existing technologies have several shortcomings. Firstly, the mixing effect between steam and wastewater is poor. Traditional steam introduction methods tend to cause steam to accumulate locally in the wastewater, resulting in uneven temperature distribution in different areas of the reaction vessel. In some areas, the temperature fails to meet the inactivation requirements, making it difficult to ensure complete inactivation of all pathogens and posing safety hazards. Secondly, the system has poor adaptability to changes in wastewater flow rate. When the wastewater flow rate fluctuates, the steam supply and stirring intensity cannot be adjusted in a timely manner, leading to unstable inactivation effects. For example, if the steam supply does not increase synchronously when the wastewater flow rate suddenly increases, the temperature of the mixed solution will drop, affecting the inactivation efficiency; conversely, when the flow rate decreases, excessive steam may lead to energy waste.

[0005] Furthermore, existing systems suffer from low control precision, relying heavily on manual operation or simple on / off control, lacking real-time monitoring and precise adjustment of key parameters such as temperature and flow rate. Simultaneously, some systems lack adaptive adjustment mechanisms for different water qualities, making it difficult to achieve personalized inactivation treatment for biologically active toxin wastewater with complex composition and varying concentrations, further reducing the reliability of treatment effectiveness. Additionally, the ease of equipment maintenance needs improvement; residual wastewater and impurities in the reaction tank are difficult to clean, and long-term operation may breed new pollutants, affecting the effectiveness of subsequent treatment. Therefore, a biologically active toxin wastewater inactivation system needs to be developed to solve these technical problems. Utility Model Content

[0006] The technical problems solved by this implementation plan are: low inactivation efficiency, complex operation, poor adaptability and insufficient safety in traditional wastewater treatment technologies.

[0007] The technical solution adopted in this implementation plan is as follows: an inactivation system for biologically active wastewater, comprising a wastewater inlet pipe, a steam inlet pipe, a first wastewater inactivation tank, a second wastewater inactivation tank, a stirring device, a flow regulating device, a temperature monitoring device, and a control system; one end of the wastewater inlet pipe is connected to the source of the biologically active wastewater to be treated, and the other end is connected to the first wastewater inactivation tank and the second wastewater inactivation tank respectively; one end of the steam inlet pipe is connected to a steam supply source, and the other end is connected to the steam inlet of the first wastewater inactivation tank and the second wastewater inactivation tank; the stirring device is installed in the first wastewater inactivation tank and the second wastewater inactivation tank. Inside the second wastewater inactivation tank, a stirring device is used to mix the wastewater and steam in the mixing tank. The flow regulating device is installed on the first wastewater inactivation tank, the second wastewater inactivation tank, and the steam input pipeline, respectively, to regulate the flow rate of wastewater and steam. The temperature monitoring device is installed inside the first wastewater inactivation tank and the second wastewater inactivation tank, to monitor the temperature of the mixed liquid in the tank in real time. The control system is electrically connected to the flow regulating device, the stirring device, and the temperature monitoring device, respectively, to control the flow regulating device to adjust the flow rate of wastewater and steam, and to control the stirring speed of the stirring device based on the temperature information fed back by the temperature monitoring device.

[0008] The beneficial effects of this implementation plan are as follows: Through automated control and precise temperature monitoring, the system achieves high efficiency and reliability in wastewater treatment. The automated control system reduces manual intervention, improving operational convenience and system response speed. Precise temperature control ensures the consistency and effectiveness of the inactivation process, thereby improving the quality of wastewater treatment. Furthermore, the system's flexibility allows it to adapt to different treatment needs, enhancing its applicability in various application scenarios. These features collectively improve wastewater treatment efficiency, reduce operating costs, and minimize potential environmental impact.

[0009] The working principle of this implementation scheme is as follows: The system first introduces the wastewater to be treated into a collection tank through a wastewater inlet pipe, and then diverts it to first and second wastewater inactivation tanks. A steam inlet pipe supplies steam to these two inactivation tanks. Inside the inactivation tanks, a stirring device ensures thorough mixing of the wastewater and steam to improve inactivation efficiency. A flow regulating device controls the flow rate of wastewater and steam, while a temperature monitoring device monitors the temperature of the mixture in real time. Based on feedback from the temperature monitoring device, the control system automatically adjusts the flow rate and stirring speed to optimize the inactivation process.

[0010] Under optimal implementation conditions, the technical problem solved is primarily that during the high-temperature inactivation process of biologically activated wastewater, gases containing toxic and harmful components are easily generated in the first and second wastewater inactivation tanks, which, if directly discharged, would cause air pollution and endanger human health. In a preferred embodiment, the technical solution adopted is as follows: both the first wastewater inactivation tank and the second wastewater inactivation tank are equipped with a gas filtration device, which is connected to an exhaust device.

[0011] Under optimal implementation conditions, the following beneficial effects are achieved: The newly added gas filtration and exhaust devices can purify the gases generated by the first and second wastewater inactivation tanks before discharge, preventing toxic and harmful gases from polluting the air and protecting the surrounding environment and human health; at the same time, it retains the original advantages of diversion treatment and automatic control, improving treatment efficiency while reducing labor costs and energy waste. The modular design has wide adaptability and convenient device maintenance, further improving the safety and environmental protection of the entire process of biological live toxin wastewater treatment.

[0012] The working principle is as follows: the gas generated in the first wastewater inactivation tank and the second wastewater inactivation tank is filtered and purified by the gas filtration device at the top of each tank to remove toxic and harmful components, and then safely discharged by the exhaust device.

[0013] Under optimal implementation conditions, the technical problem solved is to achieve precise and automated regulation of steam flow, ensuring the timeliness and accuracy of flow regulation.

[0014] In a preferred embodiment, the technical solution adopted is as follows: the flow regulating device includes a steam flow regulating valve installed on the steam input pipeline, all of which are electric regulating valves and are electrically connected to the control system.

[0015] Under optimal implementation conditions, the beneficial effects are as follows: the electric regulating valve can be automatically controlled by the control system, accurately respond to the instructions of the control system, and adjust the flow rates of wastewater and steam in a timely manner to ensure that the ratio of the two is appropriate, which is conducive to stabilizing the inactivation effect.

[0016] The working principle is as follows: the control system sends a control signal to the steam flow regulating valve based on the information fed back by the temperature monitoring device. The electric regulating valve changes the valve opening according to the received signal, thereby regulating the flow of wastewater and steam and achieving precise flow control.

[0017] In the best implementation scenario, the technical problem solved is to enhance the mixing effect of the stirring device on the steam, resulting in a more uniform mixture.

[0018] In a preferred embodiment, the technical solution adopted is as follows: the stirring device includes a stirring motor, a stirring shaft, and multiple stirring blades. The stirring motor is installed on the top of the first wastewater inactivation tank and the second wastewater inactivation tank. One end of the stirring shaft is connected to the output shaft of the stirring motor, and the other end passes through the top of the first wastewater inactivation tank and the second wastewater inactivation tank and extends into the tank. Multiple stirring blades are evenly distributed on the stirring shaft along the axial direction of the stirring shaft, and the shape of the stirring blades is an arc with an inclined angle.

[0019] Under optimal implementation conditions, the beneficial effects are as follows: multiple axially distributed arc-shaped inclined stirring blades can fully stir wastewater and steam at different depths when rotating. The arc design can enhance the driving force on the fluid, improve the stirring intensity and uniformity, and promote the mixing of the two.

[0020] The working principle is as follows: the stirring motor drives the stirring shaft to rotate, and multiple arc-shaped inclined stirring blades on the stirring shaft rotate with the shaft. During the rotation, the blades generate thrust on the surrounding wastewater and steam, causing the fluid to form a complex flow, thereby achieving full stirring and mixing of wastewater and steam at different locations in the tank.

[0021] Under optimal implementation conditions, the technical problem solved is to comprehensively and accurately monitor the temperature at different locations within the first and second wastewater inactivation tanks, avoiding the impact of inadequate local temperature monitoring on the assessment of inactivation effectiveness.

[0022] In a preferred implementation scenario, the technical solution adopted is as follows: the temperature monitoring device consists of multiple temperature sensors, which are evenly distributed in different positions within the first and second wastewater inactivation tanks, and are all electrically connected to the control system to transmit the temperature information they monitor to the control system.

[0023] Under optimal implementation conditions, the following beneficial effects are achieved: multiple temperature sensors monitor the temperature from different locations, which can comprehensively reflect the temperature distribution of the mixture in the tank, enabling the control system to more accurately determine the inactivation status, facilitate timely adjustment of parameters, and ensure the inactivation effect in each area.

[0024] The working principle is as follows: multiple temperature sensors distributed at different locations in the first and second wastewater inactivation tanks detect the temperature of the mixed liquid at their respective locations and transmit the temperature signals to the control system. The control system performs comprehensive analysis of multiple temperature information to grasp the overall temperature situation inside the tank.

[0025] 5. Under optimal implementation conditions, the technical problems solved are: mitigating flow fluctuations at the outlets of the first and second wastewater inactivation tanks, ensuring the stability of subsequent treatment, and facilitating control of the discharge rhythm.

[0026] In a preferred embodiment, the technical solution adopted includes a buffer tank connected to the outlets of the first and second wastewater inactivation tanks. The buffer tank is equipped with a liquid level monitoring device, which is electrically connected to the control system. The outlet of the buffer tank is connected to a subsequent treatment pipeline. A discharge pump is installed on the connecting pipeline between the buffer tank and the subsequent treatment pipeline. The discharge pump is electrically connected to the control system, and the control system controls the start and stop of the discharge pump based on the liquid level information fed back by the liquid level monitoring device.

[0027] Under optimal implementation conditions, the following beneficial effects are achieved: the buffer tank can temporarily store the inactivated wastewater, balance the fluctuations in the outlet flow rates of the first and second wastewater inactivation tanks, and the liquid level monitoring, in conjunction with the discharge pump, ensures stable subsequent treatment and avoids the impact of unstable flow rates on subsequent processes.

[0028] The working principle is as follows: Wastewater treated by the first and second wastewater inactivation tanks enters the buffer tank. The liquid level monitoring device monitors the liquid level in the buffer tank in real time and transmits the information to the control system. When the liquid level reaches the set upper limit, the control system controls the discharge pump to start and transport the wastewater to the subsequent treatment pipeline. When the liquid level is lower than the set lower limit, the control system controls the discharge pump to stop, thus achieving orderly control of the discharge.

[0029] Under optimal implementation conditions, the technical problems solved are: improving the adaptability of the control system to different wastewater flow rates, and quickly and accurately adjusting parameters to ensure the inactivation effect.

[0030] In a preferred implementation scenario, the technical solution adopted is as follows: the control system has pre-stored the optimal parameter values ​​of steam flow rate and stirring speed corresponding to different wastewater flow rates. When the temperature information fed back by the temperature monitoring device deviates from the preset inactivation temperature, the control system retrieves the corresponding steam flow rate and stirring speed parameters from the pre-stored parameter values ​​according to the current wastewater flow rate, and controls the flow regulating device and stirring device to make corresponding adjustments.

[0031] Under optimal implementation conditions, the following beneficial effects are achieved: the preset optimal parameter values ​​enable the control system to quickly retrieve and adjust appropriate parameters when faced with different wastewater flow rates, shortening the adjustment time, ensuring that the inactivation effect is maintained even when the flow rate changes, and improving the system's adaptability and stability.

[0032] The working principle is as follows: The control system acquires the current wastewater flow rate and temperature monitoring information in real time. When the temperature deviates from the preset value, it finds the corresponding optimal steam flow rate and stirring speed parameters from the pre-stored parameter library based on the current wastewater flow rate. Then, it sends control commands to the flow regulating device and the stirring device to make them operate according to the optimal parameters, so as to quickly adjust the temperature to the preset range.

[0033] Under optimal implementation conditions, the technical problem solved is to achieve precise inactivation control for wastewater with different components and concentrations, thereby improving the system's adaptability to complex water quality.

[0034] In a preferred implementation scenario, the technical solution employed is as follows: a water quality detection device is also installed on the wastewater input pipeline. The water quality detection device is used to detect the composition and concentration information of the wastewater and transmit the detection information to the control system. Based on the information fed back by the water quality detection device and combined with the preset optimal inactivation parameters corresponding to different water qualities, the control system performs more precise control on the flow regulation device and the stirring device.

[0035] Under optimal implementation conditions, the following beneficial effects are achieved: considering the differences in wastewater composition and concentration, the control system can make more precise adjustments to flow rate and agitation by combining water quality testing with preset parameters, ensuring that wastewater of different qualities can be effectively inactivated and improving the versatility of the system.

[0036] The working principle is as follows: the water quality detection device detects the composition and concentration of the wastewater entering the system and transmits the results to the control system; the control system calls the preset optimal inactivation parameters (such as steam flow rate, stirring speed, etc.) for the corresponding water quality based on the detected water quality information, and then controls the flow regulating device and the stirring device to operate according to these parameters to achieve targeted and precise inactivation control.

[0037] Under optimal implementation conditions, the technical problem solved is to facilitate the cleaning and maintenance of the first and second wastewater inactivation tanks, and to prevent residual wastewater and impurities from affecting the subsequent inactivation effect.

[0038] In a preferred implementation, the technical solution adopted is as follows: a drain pipe is provided at the bottom of the first wastewater inactivation tank and the second wastewater inactivation tank, and a drain valve is installed on the drain pipe. The drain valve is electrically connected to the control system. When the system needs to be cleaned and maintained, the control system controls the drain valve to open so as to discharge the wastewater and impurities remaining in the first wastewater inactivation tank and the second wastewater inactivation tank.

[0039] Under optimal implementation conditions, the following beneficial effects are achieved: it facilitates the timely discharge of residual substances from the tanks, ensures the cleanliness of the first and second wastewater inactivation tanks, prevents residual substances from polluting the wastewater to be treated later or affecting the mixing effect, and helps maintain the long-term stable operation of the system.

[0040] The working principle is as follows: When the system needs cleaning and maintenance, the control system sends a control signal to the drain valve, the drain valve opens, and the residual wastewater and impurities in the first and second wastewater inactivation tanks are discharged through the drain pipe; after the discharge is completed, the control system controls the drain valve to close so that the system can be put back into use.

Detailed Implementation

[0043] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way. Example

[0044] The components included in this embodiment are: wastewater input pipe 1, steam input pipe 2, first wastewater inactivation tank 3, second wastewater inactivation tank 17, stirring device 4, flow regulating device 5 (including steam flow regulating valve 51), temperature monitoring device 6 (including multiple temperature sensors 61), and control system 7.

[0045] Equipment Assembly: One end of the wastewater inlet pipe 1 is welded to the outlet of the storage tank of the biological live toxin wastewater source to be treated. The other end is connected to the wastewater inlet at the top of the first wastewater inactivation tank 3 and the second wastewater inactivation tank 17 via a tee and two pneumatic ball valves, respectively. One end of the steam inlet pipe 2 is connected to the steam boiler outlet via a shut-off valve. The other end is connected to the steam injection inlet at the bottom of the first wastewater inactivation tank 3 and the second wastewater inactivation tank 17 via a tee and two manual valves, respectively. The steam flow regulating valve 51 (model ZDLP-16 electric regulating valve) of the flow regulating device 5 is connected in series on the main pipe of the steam inlet pipe 2. Multiple temperature sensors 61 (PT100 type) are installed at the upper, middle, and lower positions on the inner wall of the two inactivation tanks via threaded interfaces, with the sensor probes extending 10cm into the tank. The stirring motors (Y2-90L-4 type) of the two stirring devices 4 are fixed to the center of the top of the two inactivation tanks with bolts. The stirring shafts extend into the tanks through the sealed bearings at the top of the tanks, and three layers of stirring blades are welded on the shafts. The control system 7 uses a PLC control cabinet (S7-1200 type), which connects the pneumatic valves of the water inlet pipes of the two tanks, the steam flow regulating valve 51, the two sets of stirring motors and all temperature sensors 61 through cables. The control cabinet panel is equipped with a touch screen, which can display and set the parameters of the two tanks respectively.

[0046] Production operations: 1. After checking that all components are connected correctly, turn on the power to the control cabinet, switch the system to "automatic" mode, and set the inactivation temperature of the first wastewater inactivation tank 3 to 121℃ on the touch screen.

[0047] 2. Open the manual main valve at the front end of the wastewater input pipeline 1. The control system 7 controls the inlet pneumatic valve connected to the first wastewater inactivation tank 3 to open, and the wastewater enters the first wastewater inactivation tank 3 at a flow rate of 1.5 m³ / h.

[0048] 3. When the liquid level in the first wastewater inactivation tank 3 reaches the set height, the control system 7 automatically opens the steam flow regulating valve 51 to 25% opening, and at the same time starts the stirring device 4 of the tank, with the stirring speed set to 350r / min.

[0049] 4. Temperature sensor 61 transmits temperature data to control system 7 in real time. PLC uses PID algorithm to control the opening of steam flow regulating valve 51 to accurately stabilize the temperature inside the tank at 121℃±1℃.

[0050] 5. When the first wastewater inactivation tank 3 is about to complete the treatment, the operator can start the pretreatment process of the second wastewater inactivation tank 17 on the touch screen. The system will automatically switch the inlet valve and the steam distribution valve to achieve continuous alternating operation of the two tanks.

[0051] 6. After a single batch is processed, the control system 7 closes the water inlet and steam valves of the corresponding tank, opens the bottom drain valve to discharge the inactivated wastewater to the subsequent process, and enters standby or the next batch cycle after emptying. Example

[0052] This embodiment adds the following to embodiment 1: a gas filtration device 8 and an exhaust device 9.

[0053] Equipment Assembly: Two conical gas filtration devices 8 (containing high-efficiency HEPA filters) are installed via flanges at the top exhaust ports of the first wastewater inactivation tank 3 and the second wastewater inactivation tank 17, respectively. Exhaust devices 9 (two explosion-proof centrifugal fans) are connected to the outlets of the two gas filtration devices 8 via pipes, and the fans are connected to the inverter output of the control system 7 via cables.

[0054] Production operations: 1. Start the system according to the steps in Example 1. When the inactivation vessel begins to heat and stir, vapors that may contain bioaerosols will be generated inside the vessel.

[0055] 2. The control system 7 automatically starts the corresponding exhaust device 9 fan when the stirring device 4 is started, and runs at a low speed (30Hz) to keep the inside of the inactivation tank under a slight negative pressure.

[0056] 3. The generated gas is purified by the HEPA filter in the gas filtration device 8 to ensure that the discharged gas does not contain biological active toxins and meets the biosafety emission standards.

[0057] 4. If the system detects an abnormal increase in temperature or pressure fluctuation inside the tank, the control system 7 will automatically increase the fan speed (to 50Hz) to enhance exhaust capacity and ensure system safety.

[0058] 5. After the treatment is completed, the exhaust device 9 continues to run for 5 minutes and will automatically stop after the tank cools down to ensure that there is no residual steam leakage. Example

[0059] This embodiment adds the following to embodiment 2: buffer tank 10, liquid level monitoring device 11, subsequent processing pipeline 12, discharge pump 13, sewage discharge pipeline 15, and sewage discharge valve 16.

[0060] Equipment Assembly: Buffer tank 10 is connected in parallel to the bottom outlets of the first wastewater inactivation tank 3 and the second wastewater inactivation tank 17 via pipelines, with a pneumatic discharge valve installed on each pipeline. A level monitoring device 11 (radar level gauge) is installed on the top of buffer tank 10. Subsequent treatment pipeline 12 connects to the bottom outlet of buffer tank 10, and a discharge pump 13 (corrosion-resistant centrifugal pump) is connected in series on the subsequent treatment pipeline 12, connected to the control cabinet via a frequency converter. Sewage discharge pipelines 15 connect to the lowest point discharge outlets of the two inactivation tanks, and sewage discharge valves 16 (pneumatic ball valves) are connected in series on each sewage discharge pipeline 15.

[0061] Production operations: 1. During normal system operation, the wastewater treated by the two inactivation tanks is alternately discharged into the buffer tank 10 for temporary storage through the pneumatic discharge valve.

[0062] 2. The liquid level monitoring device 11 monitors the liquid level of the buffer tank 10 in real time. When the liquid level reaches the high set value (80%), the control system 7 automatically starts the discharge pump 13 to pump the wastewater into the subsequent treatment facility. When the liquid level drops to the low set value (20%), the discharge pump 13 automatically stops.

[0063] 3. Every 48 hours of cumulative operation or before switching batches, the system automatically executes the CIP (online cleaning) procedure: closes the feed valve, injects cleaning water into the inactivation tank, starts the stirring device 4 and the heating system, and performs high-temperature cleaning and disinfection inside the tank.

[0064] 4. After CIP is completed, control system 7 opens drain valve 16 to discharge cleaning wastewater into a dedicated waste liquid collection tank. After the discharge process is completed, the valve closes, the system is ready for the next production cycle.

[0065] 5. All operation procedures, parameters, and alarm events are recorded and stored by the control system 7, forming electronic batch records that comply with GMP / FDA audit trail requirements.
