Description

Technical Field

[0001] This utility model relates to the field of biological treatment technology, specifically a biological wastewater continuous inactivation system. Background Technology

[0002] Biochemical wastewater discharged during the production process often contains some living bacteria and viruses, which are very harmful. This biochemical wastewater must be inactivated to kill the pathogens it contains before it can be discharged into the next stage of the wastewater treatment system.

[0003] In the process of inactivating biological wastewater, the wastewater is introduced into an inactivation tank, which is then heated to the required inactivation temperature. Inactivation then takes place, and after completion, the wastewater is cooled and discharged, thus completing the treatment of the biological wastewater.

[0004] However, inactivation methods often suffer from discontinuous processing, resulting in low inactivation efficiency and difficulty in meeting the needs of large-scale industrial production.

[0005] In view of this, we propose a biological wastewater continuous inactivation system. Utility Model Content

[0006] The purpose of this invention is to provide a high-activity biological wastewater inactivation treatment system to solve the problem of continuous inactivation mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A continuous biological wastewater inactivation system includes a pretreatment unit, an inactivation reaction chamber, a circulation control system, and a post-treatment and collection unit. The pretreatment unit is connected to the inactivation reaction chamber and discharges treated biological wastewater into it. The pretreatment unit is used for pre-treating the biological wastewater and regulating it to optimize the subsequent inactivation effect. The inactivation reaction chamber is used for high-efficiency inactivation. The circulation control system is mounted on the inactivation reaction chamber and controls the circulation of biological wastewater into the chamber. The circulation control system uses a pumping device to achieve continuous material circulation and precisely controls various parameters within the inactivation reaction chamber, such as flow rate, temperature, and inactivation time, to achieve optimal inactivation efficiency. The post-treatment and collection unit is connected to the inactivation reaction chamber and is used to collect the inactivated biological wastewater. The inactivated biological wastewater passes through the post-treatment and collection unit to obtain purified water resources for recycling.

[0009] Preferably, the pretreatment unit includes temperature adjustment and pH adjustment;

[0010] Temperature regulation: For most bacteria, the temperature should be adjusted to 20-40℃; for thermotolerant bacteria, it should be adjusted to 50-60℃.

[0011] pH adjustment: Adjust the pH according to the type of organisms in the biological wastewater. When the organisms are aerobic, adjust the pH to 6-9. When the organisms are anaerobic, adjust the pH to 6.5-7.5.

[0012] Preferably, the inactivation reaction chamber can employ ultraviolet inactivation, high-temperature inactivation, and chemical inactivation;

[0013] When ultraviolet inactivation is used in the inactivation reaction chamber, ultraviolet lamps are installed in the inactivation reaction chamber. The biological wastewater is inactivated by the light emitted by the ultraviolet lamps. Ultraviolet inactivation does not produce pollution and is highly environmentally friendly.

[0014] When high-temperature inactivation is used in the inactivation reaction chamber, a high-temperature steam generator is installed in the inactivation reaction chamber to inactivate biological wastewater through high temperature. High-temperature inactivation has the advantages of high inactivation efficiency and wide inactivation range.

[0015] When chemical inactivation is used in the inactivation reaction chamber, a chemical inactivating agent is added to the inactivation reaction chamber. Chemical inactivation has the advantages of fast inactivation speed and high capacity for inactivating biological wastewater.

[0016] Preferably, the circulation control system includes a heating unit, a moisturizing and inactivation unit, a cooling unit, and a discharge unit;

[0017] Heating unit: Used to control the temperature of the inactivation reaction chamber, so that the inactivation reaction chamber reaches the inactivation temperature and is kept warm;

[0019] Cooling unit: Used to cool the inactivated biological wastewater to facilitate exhaust and collection;

[0020] Discharge unit: Used to discharge the cooled biological wastewater into the post-treatment and collection unit.

[0021] Preferably, the post-processing and collection unit includes an activated carbon tower, a filter press, and a collection tank;

[0022] The inlet of the activated carbon tower is connected to the inactivation reaction chamber; the activated carbon tower filters impurities and bacteria.

[0023] The outlet of the activated carbon tower is connected to a filter press; the filter press separates the filtered biological wastewater to obtain pure water resources.

[0024] The filter press is connected to the collection tank, which is used to collect purified water.

[0025] Preferably, the filter press includes a plate and frame filter press or a diaphragm filter press;

[0026] Plate and frame filter press: It has the advantages of wide applicability and large filtration area;

[0027] Plate and frame filter presses consist of filter plates and filter frames arranged alternately. They are easy to operate and maintain, and the filtration area can be expanded by increasing the number of filter plates, resulting in a strong processing capacity.

[0028] Diaphragm filter press: It has the advantages of high-efficiency dehydration and energy saving and environmental protection;

[0029] The diaphragm filter press further reduces the moisture content of the filter cake through the diaphragm pressing function. Its low filter cake moisture content reduces the need for subsequent drying processes.

At the same time, it can be adjusted and optimized according to different scenarios, and by selecting different inactivation media, the inactivation efficiency and inactivation range are improved, which can kill a variety of types of microorganisms and viruses.

[0038] 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.

[0039] In the process of inactivating biological wastewater, the wastewater is introduced into an inactivation tank, which is then heated to the required inactivation temperature. Inactivation then takes place, and after completion, the wastewater is cooled and discharged, thus completing the treatment of the biological wastewater.

[0040] However, high-temperature inactivation often requires a lot of energy to raise the temperature to the required level, resulting in excessive energy consumption. At the same time, it may be necessary to continuously inactivate the same batch of materials to achieve complete inactivation, which means that inactivation cannot be carried out continuously and the inactivation efficiency is low.

[0041] like Figures 1 to 2 As shown, a continuous biological wastewater inactivation system includes a pretreatment unit 1, an inactivation reaction chamber 2, a circulation control system 3, and a post-treatment and collection unit 4. The pretreatment unit 1 is connected to the inactivation reaction chamber 2 and is used for pretreatment of biological wastewater. The inactivation reaction chamber 2 is used for efficient inactivation. The circulation control system 3 is loaded onto the inactivation reaction chamber 2 and controls the circulation of biological wastewater into the inactivation reaction chamber 2. The post-treatment and collection unit 4 is connected to the inactivation reaction chamber 2 and is used for collecting the inactivated biological wastewater.

[0042] Specifically, the pretreatment unit 1 is used for the pretreatment of biological wastewater. The pretreatment unit 1 adjusts the biological wastewater to optimize the subsequent inactivation effect. The pretreatment unit 1 discharges the pretreated biological wastewater into the inactivation reaction chamber 2, which is used for efficient inactivation. The circulation control system 3 is loaded onto the inactivation reaction chamber 2. The circulation control system 3 controls multiple batches of biological wastewater to circulate into the inactivation reaction chamber 2. The circulating flow of biological wastewater ensures that the inactivation reaction chamber 2 is always filled with biological wastewater to be inactivated, thereby carrying out continuous inactivation processing. The circulation control system 3 realizes the continuous circulation of materials through a pumping device, so that multiple batches of materials circulate for inactivation, ensuring the continuity of inactivation. It also precisely controls various parameters in the inactivation reaction chamber 2, such as flow rate, temperature, and inactivation time, to achieve the best inactivation efficiency.

[0043] Preferably, the biological wastewater is divided into at least three portions, which are sequentially circulated into the inactivation reaction chamber 2 for inactivation. However, when the three portions of biological wastewater are about to be inactivated, the remaining three portions are added to the circulation system to replace the last portion of the previous batch of inactivated biological wastewater, and the circulation is repeated. This ensures that each portion of biological wastewater is inactivated, and multiple inactivation processes are performed to guarantee the quality of inactivation and continuous inactivation. The post-treatment and collection unit 4 is connected to the inactivation reaction chamber 2 and is used to collect the inactivated biological wastewater. After inactivation, the biological wastewater passes through the post-treatment and collection unit 4 to obtain pure water resources for recycling.

[0044] In this embodiment, the pretreatment unit 1 includes temperature adjustment and pH adjustment; temperature adjustment:

[0045] Specifically, for most bacteria, the temperature should be adjusted to 20-40℃, while for thermotolerant bacteria, it should be adjusted to 50-60℃; pH adjustment: adjust according to the type of organisms in the wastewater. When the organisms are aerobic, adjust the pH to 6-9, and when the organisms are anaerobic, adjust the pH to 6.5-7.5.

[0046] In this embodiment, the inactivation reaction chamber 2 can employ ultraviolet inactivation, high-temperature inactivation, and chemical inactivation;

[0047] Specifically, when ultraviolet (UV) inactivation is used in inactivation chamber 2, UV lamps are installed inside. The biological wastewater is inactivated by the light emitted from the UV lamps. UV inactivation does not produce pollution and is highly environmentally friendly. When high-temperature inactivation is used in inactivation chamber 2, a high-temperature steam generator is installed inside. The biological wastewater is inactivated by high temperature. High-temperature inactivation has the advantages of high inactivation efficiency and wide inactivation range. When chemical inactivation is used in inactivation chamber 2, chemical inactivating agents are added to inactivation chamber 2. Chemical inactivation has the advantages of fast inactivation speed and high capacity for inactivating biological wastewater.

[0048] Preferably, this embodiment uses ultraviolet inactivation, which does not generate high temperatures, thus improving the safety of the inactivation process. At the same time, ultraviolet inactivation does not generate pollution and is highly environmentally friendly.

[0049] In this embodiment, the circulation control system 3 includes a heating unit 31, a moisturizing and inactivating unit 32, a cooling unit 33, and a discharge unit 34;

[0050] Specifically, the heating unit 31 is used to control the temperature of the inactivation reaction chamber 2, so that the inactivation reaction chamber 2 reaches the inactivation temperature and is kept warm; the moisturizing inactivation unit 32 controls the inactivation reaction chamber 2 to start the ultraviolet lamp; the cooling unit 33 is used to cool down the biological wastewater after inactivation, so as to facilitate exhaust and collection; the discharge unit 34 is used to discharge the cooled biological wastewater into the post-treatment and collection unit 4.

[0051] In this embodiment, the post-processing and collection unit 4 includes an activated carbon tower 41, a filter press 42, and a collection tank 43;

[0052] The inlet end of the activated carbon tower 41 is connected to the inactivation reaction chamber 2;

[0053] The outlet end of the activated carbon tower 41 is connected to the filter press 42;

[0054] The filter press 42 is connected to the collection tank 43;

[0055] Specifically, the biological wastewater that has been inactivated in the inactivation reaction chamber 2 enters the activated carbon tower 41, where the activated carbon tower 41 filters out impurities and bacteria. The filter press 42 separates the biological wastewater through solid-liquid separation to obtain pure water resources. The purified water is then sent to the collection 43 for storage.

[0056] In this embodiment, the filter press 421 includes a plate and frame filter press or a diaphragm filter press;

[0057] Specifically, plate and frame filter presses have the advantages of wide applicability and large filtration area; they consist of filter plates and filter frames arranged alternately, are easy to operate and maintain, and can expand the filtration area by increasing the number of filter plates, resulting in strong processing capacity; diaphragm filter presses have the advantages of high-efficiency dehydration and energy saving and environmental protection.

[0058] The diaphragm filter press further reduces the moisture content of the filter cake through the diaphragm pressing function. Its low filter cake moisture content reduces the need for subsequent drying processes.

[0059] This utility model Figure 1 This is a flow chart of a continuous biological wastewater inactivation system. The chart illustrates the detailed working process of biological wastewater inactivation. The biological wastewater undergoes temperature and pH adjustment in the pretreatment unit 1. After treatment, the biological wastewater enters the inactivation reaction chamber 2 under the control of the circulation control system 3. In the inactivation reaction chamber 2, it is irradiated by ultraviolet lamps, heated by the heating unit 31, moisturized by the inactivation unit 32, and cooled by the cooling unit 33. Then, it is discharged from the inactivation reaction chamber 2 by the discharge unit 34. The discharged wastewater enters the post-treatment and collection unit 4 and undergoes preliminary purification of odors and impurities in the wastewater by the activated carbon tower 41. After purification, it is sent to the filter press 42 for solid-liquid separation. The separated solids are sent to the collection tank 43 for storage, thus obtaining pure water resources.
