Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a deep-water targeted aeration system for microorganisms. Background Technology

[0002] In the field of wastewater treatment technology, the synergistic effect of aeration and microbial agents is an important means to improve water quality. At present, commonly used aeration equipment has many limitations: for example, some aeration equipment mainly relies on surface reoxygenation, which is difficult to effectively improve the hypoxic state in deep water areas; although some micro-nano aeration systems can act on deep water bodies, they have problems such as high energy consumption, easy clogging of diffusers, and the need for regular maintenance.

[0003] Meanwhile, microbial agents face significant challenges during application: after application, the agents are easily dispersed by water flow and are difficult to remain in the target polluted area and exert a degradation effect, requiring frequent replenishment to maintain the effect and increasing treatment costs; moreover, traditional application methods cannot accurately control the distribution of agents according to the differences in pollutant concentrations in different areas of the water body, resulting in a mismatch between the microbial community and the pollutant concentration, which affects treatment efficiency.

[0004] Furthermore, existing systems lack the ability to treat water at different depths, failing to target aeration and microbial agent application based on the pollution differences between deep and shallow water areas. This results in uneven overall treatment effects and makes it difficult to meet the treatment needs of complex aquatic environments. Therefore, there is an urgent need for a treatment system that can achieve precise aeration in deep water areas, improve the efficiency of microbial agent action, and adapt to different water depths. Utility Model Content

[0005] The purpose of this invention is to provide a deep-water targeted aeration system for microorganisms, aiming to solve the aforementioned technical problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A deep-water targeted aeration system for microorganisms includes an ultra-nano dissolved aerobic reoxygenation system and a microbial agent dosing tank. The ultra-nano dissolved aerobic reoxygenation system and the microbial agent dosing tank are installed on the bank of the water body to be treated. The output port of the ultra-nano dissolved aerobic reoxygenation system is provided with a water outlet pipe. The outlet of the water outlet pipe is submerged in the water body to be treated and connected to the input end of a diffusion water outlet structure. The diffusion water outlet structure is provided with a depth adjustment mechanism along the vertical direction. The diffusion water outlet structure adjusts the vertical depth of its input end in the water body to be treated through the depth adjustment mechanism. The lifting end of the depth adjustment mechanism is provided with a water quality detection component.

[0008] The output end of the microbial agent dosing box is equipped with a dosing pipeline, which is connected to the water outlet pipeline.

[0009] In a preferred embodiment of this utility model, the ultra-nano dissolved oxygenation system includes an equipment room, in which a system host and an oxygen tank are installed. The oxygen tank is connected to the oxygen supply end of the system host through a pipeline. The input end of the system host is provided with a water inlet pipeline. A water inlet pump is submerged at the bottom of the water body to be treated. The water inlet pipeline extends into the water body to be treated and is fixedly installed at the output end of the water inlet pump.

[0010] In a preferred embodiment of this utility model, a metering pump and a check valve are sequentially arranged in the dosing pipeline along the direction away from the microbial agent dosing tank, and a flow control valve is provided at a point where the water outlet pipeline connects to the dosing pipeline.

[0011] In a preferred embodiment of this utility model, the diffusion water outlet structure includes a float ring that floats on the surface of the water body to be treated. A base plate is fixedly installed at the bottom of the float ring to achieve waterproofing inside the float ring. The depth adjustment mechanism is located in the middle of the float ring and is fixedly installed on the top surface of the base plate. Multiple counterweights are evenly arranged around the bottom surface of the base plate by cables.

[0012] In a preferred embodiment of this utility model, the depth adjustment mechanism includes a guide rod, a sliding sleeve slidably connected to the surface of the guide rod, the sliding sleeve being fixedly installed with the base plate to enable the guide rod to slide up and down, a transmission rack being fixedly installed parallel to one side of the guide rod, a drive gear meshing with one side of the transmission rack, the drive gear being fixedly installed with the output end of a reduction motor, the reduction motor being fixedly installed on the top surface of the base plate, a release head being fixedly installed at the bottom end of the guide rod below the water surface, the input end of the release head being fixedly installed with one end of the water outlet pipe, and a quick-connect high-pressure hose being fixedly installed at the output end of the bottom of the release head.

[0013] In a preferred embodiment of this utility model, the water quality testing component includes a dissolved oxygen meter (DO), a COD analyzer, an NH3-N analyzer, and a chlorophyll a monitor, all located in the equipment room.

[0014] The probes of the dissolved oxygen analyzer, COD analyzer, NH3-N analyzer, and chlorophyll a monitor are all housed within the mounting frame, which is fixedly mounted on the guide rod near the release head.

[0015] The beneficial effects of this utility model are:

[0016] 1. Precise and targeted treatment of deep water areas: By setting up a depth adjustment mechanism (guide rod, transmission rack and geared motor in combination), the vertical depth of the diffusion water outlet structure can be flexibly adjusted to achieve targeted aeration and bacterial agent delivery in different water depth areas. This solves the problem that traditional systems cannot take into account the treatment of deep water areas, and is especially suitable for deep water bodies such as reservoirs and deep pools.

[0017] 2. Improve the synergistic efficiency of aeration and microbial agents: The ultra-nano dissolved oxygenation system can produce supersaturated oxygen-enriched water with no visible bubbles and a long oxygen residence time, which can efficiently increase the dissolved oxygen concentration in the water. At the same time, the microbial agents are mixed with the oxygen-enriched water through the dosing pipeline and then added, so that the agents are in a suitable aerobic environment, which enhances their activity and degradation ability, reduces the loss of agents due to diffusion, and reduces the frequency of replenishment.

[0018] 3. Adaptable to diverse pollution scenarios: The diffused water outlet structure can be distributed in a matrix or point shape through multiple sets of water outlet pipes (such as 6 sets of water outlets to adapt to open water areas or sewage outlets), and the flow rate of each set can be adjusted by the flow control valve. It can accurately control the pollutant concentration difference in different areas to ensure that all areas of the water body are effectively treated; and the number of water outlet sets can be flexibly adjusted according to the size of the water body, making it highly adaptable.

[0019] 4. Stable and easy to maintain: The diffusion structure is floated by a float ring and fixed by a counterweight, combined with components such as a quick-connect high-pressure hose, to ensure the stability of the system in the water. The ultra-nano dissolved oxygenation system has no diffuser design that is prone to clogging, which reduces maintenance costs and improves the reliability of long-term operation.

[0020] 5. Optimize treatment costs: By precisely controlling the aeration intensity and the amount of microbial agent, the waste of resources caused by "over-aeration" and "blindly adding microorganisms" in traditional systems is avoided; at the same time, the synergistic effect of microbial agents and oxygen-enriched water improves the degradation efficiency of a unit of microbial agent, further reducing treatment costs.

[0026] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0027] Example:

[0028] like Figures 1-4 This embodiment provides a deep-water targeted aeration system for microorganisms, including an ultra-nano dissolved aeration system 1 and a microbial agent dispensing box 2. The ultra-nano dissolved aeration system 1 and the microbial agent dispensing box 2 are set on the bank of the water body to be treated. The outlet of the ultra-nano dissolved aeration system 1 is provided with a water outlet pipe 15. The outlet of the water outlet pipe 15 is submerged in the water body to be treated and connected to the input end of the diffusion water outlet structure 3. The diffusion water outlet structure 3 is provided with a depth adjustment mechanism 32 in the vertical direction. The depth adjustment mechanism 32 adjusts the vertical depth of its input end in the water body to be treated. The lifting end of the depth adjustment mechanism 32 is provided with a water quality detection component 4.

[0029] The output end of the microbial agent dosing tank 2 is equipped with a dosing pipe 23, which is connected to the water outlet pipe 15.

[0030] In a preferred embodiment of this utility model, the ultra-nano dissolved oxygenation system 1 further includes an equipment room 17, in which a system host 11 and an oxygen tank 12 are installed. The oxygen tank 12 is connected to the oxygen supply end of the system host 11 through a pipeline. The input end of the system host 11 is provided with a water inlet pipeline 14, which extends into the water body to be treated and is fixedly installed at the output end of the water pump 13. The water pump 13 is submerged at the bottom of the water body to be treated.

[0031] In a preferred embodiment of this utility model, the dosing pipeline 23 is further provided with a metering pump 21 and a check valve 22 in sequence along the direction away from the microbial agent dosing tank 2, and a flow control valve 16 is provided at a point after the water outlet pipeline 15 is connected to the dosing pipeline 23.

[0032] Specifically, such as Figure 1 As shown, the ultra-nano dissolved oxygenation system 1 and the microbial agent dosing box 2 are connected in series, with their outlet pipes 15 and dosing pipes 23 connected together. The main pipe is controlled by the flow control valve 16 and connected to the diffusion outlet structure 3 for release. Since the water pollution conditions vary, a water quality detection component 4 is set up and fixedly installed with the lifting end of the depth adjustment mechanism 32 to dynamically detect the water quality parameters of different water depths. This allows for targeted treatment plans, reasonable control of the oxygen enrichment rate and the types of bacteria added by the ultra-nano dissolved oxygenation system 1, as well as the mixing ratio of the two. This results in immediate sewage treatment effects, improved treatment efficiency, reduced treatment costs, and energy conservation and emission reduction.

[0033] On the other hand, the concentration of pollutants may vary in different areas. Multiple outlet pipes (six in this case) can be set up to connect to the diffusion outlet. The six outlets are arranged in a matrix (with a spacing of 50 to 100 meters, mainly for open water areas) or distributed in a point (mainly for each outlet) in the water body. If the water body is small, the number of outlet groups can be reduced.

[0034] The flow rate of each group of water outlets is controlled by a solenoid valve in the outlet pipe 15. Based on the data transmitted from the monitoring equipment at the outlet end, the flow rate of each outlet pipe 15 is adjusted according to the degree of pollution. The outlet end is equipped with a height adjustment rod 32, which can be set at different depths and monitor water quality indicators at the control terminal, while simultaneously adjusting the flow rate of the outlet pipe 15 to ensure that the water quality of the entire water body is purified.

[0035] Through the synergistic cooperation of the above structures, and by intelligently controlling the aerators and microbial ecological restoration, precise control and treatment can be applied to different levels of pollution in the water at different times, ensuring that the water quality always meets the standards for its functional use.

[0036] In a preferred embodiment of this utility model, the diffusion water outlet structure 3 further includes a float ring 31, which floats on the surface of the water body to be treated. A base plate 35 is fixedly installed at the bottom of the float ring 31 to achieve waterproofing inside the float ring 31. A depth adjustment mechanism 32 is set in the middle of the float ring 31 and fixedly installed on the top surface of the base plate 35. Multiple counterweights 36 are evenly arranged around the bottom surface of the base plate 35 by cables.

[0037] In a preferred embodiment of this utility model, the depth adjustment mechanism 32 further includes a guide rod 321, a sliding sleeve 325 slidably connected to the surface of the guide rod 321, the sliding sleeve 325 being fixedly installed with the base plate 35 to realize the up and down sliding of the guide rod 321, a transmission rack 322 being fixedly installed parallel to one side of the guide rod 321, a drive gear 323 meshing with one side of the transmission rack 322, the drive gear 323 being fixedly installed with the output end of the reduction motor 324, the reduction motor 324 being fixedly installed on the top surface of the base plate 35, a release head 33 being fixedly installed at the bottom end of the guide rod 321 below the water surface, the input end of the release head 33 being fixedly installed with one end of the water outlet pipe 15, and a quick-connect high-pressure hose 34 being fixedly installed at the output end of the bottom of the release head 33.

[0038] Specifically, such as Figures 2-3 As shown, the water quality detection component 4 detects the water quality at different depths and ranges in the water body to be treated and transmits the data back to the shore equipment room 17. The system host 11 analyzes the data and controls the start of the reduction motor 324 of the remote control depth adjustment mechanism 32. The reduction motor 324 drives the drive gear 323 to rotate, which in turn drives the transmission rack 322 to move the guide rod 321 up and down. This allows the release head 33 at the bottom of the guide rod 321 and the probe 42 in the mounting frame 41 to move up and down. The probe 42 can be connected to various monitoring devices in the equipment room 17 via wired connection along the water outlet pipe 15, or via wireless communication. This enables water quality detection and release of oxygen-rich water and bacteria at different water depths, achieving targeted aeration and thus treating wastewater appropriately according to local conditions.

[0039] In a preferred embodiment of this utility model, the water quality testing component 4 further includes a dissolved oxygen (DO) meter, a COD analyzer, an NH3-N analyzer, and a chlorophyll a monitor, all installed in the equipment room 17.

[0040] The probes 42 of the dissolved oxygen analyzer, COD analyzer, NH3-N analyzer and chlorophyll a monitor are all set inside the mounting frame 41, which is fixedly installed on the guide rod 321 near the release head 33.

[0041] Specifically, such as Figure 1 , 3 As shown, the application scenarios and working principles of various water quality testing instruments for different polluted environments are as follows:

[0042] 1. The dissolved oxygen concentration in the water measured by the DO dissolved oxygen meter is ≤3mg / L.

[0043] When the ultra-nano dissolved oxygenation system 1 is started, the water pump 13 draws water into the system host 11, the oxygen tank 12 supplies oxygen to the system host 11, and the water and oxygen are mixed under pressure in the system host 11 to form supersaturated oxygen-rich water, which is discharged through the water outlet pipe 15 and can be transported to the upper layer of silt at the bottom of the water body.

[0044] When the dissolved oxygen concentration in the water reaches ≥5 mg / L, the pump can be shut down immediately, or shut down after a few hours based on experience with the rate of oxygen concentration decrease. This ensures the water remains in an aerobic state, preventing blackening and odor, while also meeting the oxygen requirements of aquatic animals.

[0045] 2. When the COD analyzer detects that the water quality exceeds the standard (40 mg / L for Class V water, 30 mg / L for Class IV water, and 20 mg / L for Class III water); when the ammonia nitrogen analyzer detects that the water quality exceeds the standard (2.0 mg / L for Class V water, 1.5 mg / L for Class IV water, and 1.0 mg / L for Class III water);

[0046] For excessive COD and ammonia nitrogen levels, compound microbial agents (mainly containing Bacillus, Pseudomonas, and yeast) are mainly added, along with nitrifying bacteria.

[0047] The dosage of microbial agent should be configured according to the following principles: for light pollution (COD < 50 mg / L, ammonia nitrogen < 5 mg / L), the dosage of microbial agent is [amount] per 1000 m³. 3 Add 10-20g of compound bacterial agent and 20-50g of nitrifying bacteria to the water body; for moderate pollution (COD 50-200mg / L, ammonia nitrogen 5-20mg / L), the bacterial agent dosage is per 1000m³. 3 Add 20-100g of compound bacterial agent and 50-200g of nitrifying bacteria to the water body; for heavily polluted water (COD>200mg / L, ammonia nitrogen>20mg / L), the bacterial agent dosage is [per 1000m³]. 3 Add 100-200g of bacterial agent and 200-1000g of nitrifying bacteria to the water body;

[0048] The effective viable count must be ≥1×10 9 CFU / g, if the concentration is different, it needs to be adjusted proportionally; set the dosing cycle. After the first dosing, if the water quality still does not meet the standard, add again at a frequency of once every two weeks for light pollution, once a week for moderate pollution, and twice a week for heavy pollution at the beginning, and then once a week as appropriate in the later stage.

[0049] The prepared microbial agent solution is placed in the microbial agent dosing tank 2, and the dosage is set. The metering pump 21 pumps the agent solution into the ultra-nano water outlet pipe 15, where it combines with oxygen-enriched water and diffuses into the external water body, ensuring that the bacteria are always in a suitable aerobic environment to achieve better treatment results. During this process, the dissolved oxygen concentration in the water body must always be ≥2mg / L. If the dissolved oxygen concentration in the water body always meets the standard, the valve of the oxygen tank 12 can be closed during dosing, and water can be drawn in from the inlet pipe 14 by the inlet pump 13. After the water body merges with the dosing pipe 23 in the outlet pipe 15, the mixed water is discharged from the outlet end.

[0050] 3. The chlorophyll monitor detected that the algae density exceeded the standard.

[0051] The algal density was found to be excessive by a chlorophyll monitor. The warning threshold was ChL-a > 10 μg / L or blue-green algae > 10000 ceLLs / mL.

[0052] Prepare a blue enzyme solution (environmentally friendly, with low toxicity to fish and shrimp) and add it according to the following principles: when ChL-a is between 10 and 30 μg / L, the dosage is 1 to 1.5 g / m³. 3 Add the product and monitor the algal density every 24 hours; when ChL-a > 30 μg / L, the dosage should be 1.5–2.5 g / m³. 3 Add the solution to maintain dissolved oxygen levels ≥4 mg / L in the water, preventing excessive algal death that could suffocate fish and other aquatic organisms. Monitor algal density every twelve hours. When the density of blue-green algae is >50,000 ceLLs / mL, increase the dosage to 2–3 g / m³. 3 In addition to physical removal, algae density should be monitored every 6-8 hours. When adding the agent, simultaneously activate the ultra-nano dissolved oxygen reoxygenation system 11 to ensure dissolved oxygen in the water remains ≥4 mg / L, preventing excessive algal death and oxygen depletion that could suffocate fish and other aquatic organisms. When ChL-a <10 μg / L, 0.5 g / m³ can be added every seven days. 3 Blue Enzyme Solution helps prevent recurrence.

[0053] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
