Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and in particular relates to a rapid cultivation system for multiple types of photoparticles for the treatment of high-salt wastewater. Background Technology

[0002] Microalgae-based wastewater treatment technology is considered an eco-friendly wastewater treatment method due to its low energy consumption, low greenhouse gas emissions, and resource utilization potential, and it has broad application prospects, especially in the treatment of high-salinity wastewater such as marine aquaculture wastewater.

[0003] However, traditional microalgae treatment systems generally suffer from prominent problems such as low biomass concentration, limited pollutant removal capacity, difficulty in harvesting microalgae, and poor resistance to environmental fluctuations, which seriously restrict their engineering applications.

[0004] Granular microalgae, also known as photoparticles, are dense spherical structures formed by the aggregation of photosynthetic and non-photosynthetic microorganisms such as eukaryotic microalgae and cyanobacteria. They have excellent settling properties and can simultaneously remove organic matter and nitrogen and phosphorus from wastewater through the synergistic effect of algae and bacteria.

[0005] Nevertheless, existing photoparticle cultivation technologies still face bottlenecks such as long mature particle formation cycles, poor particle structural stability, susceptibility to pyrolysis, and difficulty in adapting to high-salt environmental stress. More importantly, a single reactor system can typically only cultivate a single type of photoparticle, failing to meet the diverse morphological, particle size, and structural requirements of different application scenarios, thus limiting the promotion and large-scale application of this technology in various wastewater treatment fields.

[0006] Therefore, there is an urgent need for a rapid cultivation system for multiple types of photoparticles for the treatment of high-salt wastewater. Summary of the Invention

[0007] The purpose of this invention is to provide a rapid cultivation system for multiple types of photoparticles for high-salt wastewater treatment, in order to solve the above-mentioned problems.

[0008] To achieve the above objectives, the present invention provides the following solution: A rapid cultivation system for multiple types of photoparticles for high-salinity wastewater treatment includes: The optical particle reaction chamber has an upflow chamber formed by a partition assembly in the middle of the optical particle reaction chamber, and a downflow chamber between the optical particle reaction chamber and the partition assembly, the downflow chamber being connected to the upflow chamber; The photoparticle reaction chamber is detachably connected to the partition assembly. The bottom of the photoparticle reaction chamber is connected to an aeration structure; The photoparticle reaction chamber is connected to a water inlet structure, an algae removal structure, and a drainage structure. Light source plates are respectively installed on both sides of the optical particle reaction chamber, and timer switches are connected to the light source plates. When the diaphragm assembly consists of a ceramic membrane assembly and a short diaphragm, it operates in a continuous flow mode. When the partition assembly consists of long partitions, it is in the sequential batch operation mode.

[0009] Optionally, the photoparticle reaction chamber includes an upper reaction chamber and a lower reaction chamber, and the partition assembly is detachably connected to the upper reaction chamber; The bottom of the upper reaction chamber and the top of the lower reaction chamber are connected; The bottom of the lower reaction chamber is connected to the air outlet of the aeration structure.

[0010] Optionally, the aeration structure includes a cup lid, the bottom of the lower reaction chamber is provided with a cup opening, the cup lid is sleeved on the outside of the cup opening, and the cup opening and the cup lid are threaded together to form an aeration chamber; The aeration chamber is equipped with a microporous aeration plate. After the cup lid is screwed on the cup opening, the cup opening abuts against the microporous aeration plate and clamps and fixes it between the cup opening and the cup lid. The cup lid is connected to a gas flow meter and an aeration pump.

[0011] Optionally, the water inlet structure includes a water inlet located on one side of the top of the upper reaction chamber. The water inlet is connected to one end of a first peristaltic pump, and the other end of the first peristaltic pump is connected to a water inlet tank through a water inlet pipe.

[0012] Optionally, the algae removal structure includes an algae removal port connected to one side of the bottom of the lower reaction chamber, and the algae removal port is connected to a light particle collection box.

[0013] Optionally, an overflow valve is connected to one side of the top of the upper reaction chamber, and the overflow valve is connected to the light particle collection box.

[0014] Optionally, the drainage structure includes a water outlet tank, which is connected to a second peristaltic pump via a water outlet pipe. The second peristaltic pump is connected to a time relay and is connected to the upper reaction chamber.

[0015] Optionally, when the partition assembly consists of a ceramic membrane assembly and a short partition, the outlet end of the ceramic membrane assembly is connected to the inlet end of the second peristaltic pump; It also includes a level controller and a water level monitoring probe, the level controller and the water level monitoring probe being connected to a level controller, which is connected to the first peristaltic pump.

[0017] Optionally, when the partition assembly consists of long partitions, the inlet of the second peristaltic pump is connected to the bottom side of the upper reaction chamber through the outlet.

[0018] Compared with the prior art, the present invention has the following advantages and technical effects: This invention provides a rapid cultivation system for multiple types of photoparticles for high-salinity wastewater treatment. By installing a detachable partition assembly between the upper and lower reaction chambers, which, in conjunction with the reactor body, forms a central upflow chamber and two side downflow chambers, suspended algae and bacteria circulate within the reactor under aeration conditions. This enables rapid granulation, yielding photoparticles with regular, dense structures and excellent settling properties, significantly improving reactor start-up efficiency. By adjusting the composition of the partition assembly, the system can switch between continuous flow and batch operation modes. Combined with adjustments to operating conditions (food-to-microbe ratio and hydraulic retention time), photoparticles of different colors, sizes, and structures can be directionally cultivated. This system possesses applicability to multiple scenarios and engineering application potential, solving the problem that most existing photoparticle systems can only cultivate a single type of photoparticle.

[0019] Under high salt stress, the system can achieve a total organic carbon removal rate of over 80%, ammonia nitrogen removal rate of over 90%, and phosphorus removal rate of over 70%, and can operate stably for over 100 days. This effectively solves the technical problems of poor operational stability and low efficiency in nitrogen, phosphorus, and carbon removal under high salt conditions in traditional biological treatment processes. Through the coordination of the upper reaction chamber, lower reaction chamber, and aeration chamber, when aeration stops, the photoparticles can rapidly deposit into the lower reaction chamber and aeration chamber within one minute, and are ultimately guided to the photoparticle collection box through the algae discharge port. This achieves rapid biomass harvesting, simplifies the operation process, and reduces operating costs. Attached Figure Description

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 6 This invention discloses a rapid cultivation system for multiple types of photoparticles for high-salinity wastewater treatment, comprising: The optical particle reaction chamber 11 has an upflow chamber 28 formed by the partition assembly 10 in the middle of the optical particle reaction chamber 11, and a downflow chamber 27 between the optical particle reaction chamber 11 and the partition assembly 10. The downflow chamber 27 is connected to the upflow chamber 28. The photoparticle reaction chamber 11 and the partition assembly 10 are detachably connected. The bottom of the photoparticle reaction chamber 11 is connected to an aeration structure; The photoparticle reaction chamber 11 is connected to a water inlet structure, an algae removal structure, and a drainage structure. Light source plates 21 are respectively installed on both sides of the light particle reaction chamber 11, and timer switches 22 are connected to the light source plates 21. When the partition assembly 10 consists of the ceramic membrane assembly 26 and the short partition 15-1, it operates in a continuous flow mode. When the partition assembly 10 consists of long partitions 15-2, it is in the sequential batch operation mode.

[0024] The photoparticle reactor 11 has an upflow chamber 28 formed by baffle assemblies 10 in the middle, and a downflow chamber 27 between the photoparticle reactor 11 and the baffle assemblies 10, which are interconnected with the upflow chamber 28. The photoparticle reactor 11 and the baffle assemblies 10 are detachably connected, facilitating the replacement of different types of baffle assemblies 10. An aeration structure is connected to the bottom of the photoparticle reactor 11 to introduce air into the reactor and drive the algae solution circulation. The photoparticle reactor 11 also has an inlet structure, an algae discharge structure, and a drainage structure to respectively realize the input of wastewater, the collection of photoparticles, and the discharge of treated water. Light source plates 21 are respectively installed on both sides of the photoparticle reactor 11, and the light source plates 21 are connected to timer switches 22 to control the light-dark cycle. When the baffle assembly 10 consists of a ceramic membrane assembly 26 and short baffles 15-1, the system operates in continuous flow mode; when the baffle assembly 10 consists of long baffles 15-2, the system operates in batch mode. With the combination of the above structures, the system can make the algal liquid circulate between the upflow chamber 28 and the downflow chamber 27 under aeration conditions, accelerate the formation of light particles, and cultivate different types of light particles according to the operating mode.

[0025] As an optional implementation, the photoparticle reaction chamber 11 includes an upper reaction chamber 12 and a lower reaction chamber 13, and the partition assembly 10 is detachably connected to the upper reaction chamber 12. The bottom of the upper reaction chamber 12 and the top of the lower reaction chamber 13 are connected; The bottom of the lower reaction chamber 13 is connected to the air outlet of the aeration structure.

[0026] The photocatalytic particle reaction chamber 11 includes an upper reaction chamber 12 and a lower reaction chamber 13. A baffle assembly 10 is detachably connected to the upper reaction chamber 12, facilitating replacement of the baffle assembly 10 according to different operating modes. The bottom of the upper reaction chamber 12 and the top of the lower reaction chamber 13 are interconnected, allowing the algal solution to flow freely between the two chambers. The bottom of the lower reaction chamber 13 is connected to the air outlet of the aeration structure. The airflow generated by aeration flows upward from the bottom, driving the algal solution to circulate between the rising flow chamber 28 and the falling flow chamber 27, promoting the aggregation and granulation of suspended algae.

[0027] As an optional implementation, the aeration structure includes a cup cover 30, a cup opening 29 at the bottom of the lower reaction chamber 13, the cup cover 30 is sleeved on the outside of the cup opening 29, and the cup opening 29 and the cup cover 30 are threaded together to form an aeration chamber 25. A microporous aeration plate 24 is provided in the aeration chamber 25. After the cup lid 30 is screwed onto the cup mouth 29, the cup mouth 29 abuts against the microporous aeration plate 24 and clamps and fixes it between the cup mouth 29 and the cup lid 30. The cup lid 30 is connected to a gas flow meter 31 and an aeration pump 14.

[0028] The aeration structure includes a cup lid 30. A cup opening 29 is located at the bottom of the lower reaction chamber 13. The cup lid 30 is fitted over the outside of the cup opening 29, and the cup opening 29 and the cup lid 30 are threaded together to form an aeration chamber 25. A microporous aeration plate 24 is installed inside the aeration chamber 25. When the cup lid 30 is screwed onto the cup opening 29, the cup opening 29 abuts against the microporous aeration plate 24, clamping and fixing it between the cup opening 29 and the cup lid 30, thus reliably fixing the microporous aeration plate 24. The cup lid 30 is connected to a gas flow meter 31 and an aeration pump 14. The gas flow meter 31 controls the aeration volume, and the aeration pump 14 provides the air source. The air is evenly dispersed through the microporous aeration plate 24 and then enters the lower reaction chamber 13 and the upper reaction chamber 12.

[0029] As an optional implementation, the water inlet structure includes a water inlet 23 located on one side of the top of the upper reaction chamber 12. The water inlet 23 is connected to one end of the first peristaltic pump 4, and the other end of the first peristaltic pump 4 is connected to the water inlet tank 1 through the water inlet pipe 2.

[0030] The water inlet structure includes a water inlet 23 located on one side of the top of the upper reaction chamber 12. The water inlet 23 is connected to one end of the first peristaltic pump 4. The other end of the first peristaltic pump 4 is connected to the water inlet tank 1 through the water inlet pipe 2. The high-salt wastewater is pumped from the water inlet tank 1 into the photoparticle reaction chamber 11 by the first peristaltic pump 4.

[0031] As an optional implementation, the algae discharge structure includes an algae discharge port 20 connected to one side of the bottom of the lower reaction chamber 13, and the algae discharge port 20 is connected to a light particle collection box 19.

[0032] The algae discharge structure includes an algae discharge port 20 connected to one side of the bottom of the lower reaction chamber 13, which is connected to a light particle collection box 19. When aeration stops, the matured light particles settle rapidly to the bottom of the light particle reaction box 11 under gravity, pass through the lower reaction chamber 13, are discharged from the algae discharge port 20, and enter the light particle collection box 19 to achieve rapid biomass harvesting.

[0033] As an optional implementation, an overflow valve 16 is connected to one side of the top of the upper reaction chamber 12, and the overflow valve 16 is connected to the light particle collection box 19.

[0034] An overflow valve 16 is connected to one side of the top of the upper reaction chamber 12, and the overflow valve 16 is connected to the light particle collection box 19. The overflow valve 16 is located above the liquid surface in the light particle reaction box 11. When the system malfunctions and the liquid level rises abnormally, the mixed algal solution can overflow through the overflow valve 16 and be discharged into the light particle collection box 19, which plays a safety protection role and prevents liquid from overflowing and polluting the environment.

[0035] As an optional implementation, the drainage structure includes a water outlet tank 17, which is connected to a second peristaltic pump 9 via a water outlet pipe 6. The second peristaltic pump 9 is connected to a time relay 8 and is connected to the upper reaction chamber 12.

[0036] The drainage structure includes an outlet tank 17, which is connected to a second peristaltic pump 9 via an outlet pipe 6. The second peristaltic pump 9 is connected to a time relay 8 and is connected to the upper reaction chamber 12. The time relay 8 controls the intermittent operation of the second peristaltic pump 9, so that the treated compliant effluent is discharged from the particle reaction chamber 11 and enters the outlet tank 17 under the suction action of the second peristaltic pump 9.

[0037] As an optional implementation, when the partition assembly 10 is composed of a ceramic membrane assembly 26 and a short partition 15-1, the outlet end of the ceramic membrane assembly 26 is connected to the inlet end of the second peristaltic pump 9. It also includes a level controller water level monitoring probe 3, which is connected to a level controller 5, and the level controller 5 is connected to the first peristaltic pump 4.

[0038] When the baffle assembly 10 consists of the ceramic membrane assembly 26 and the short baffle 15-1, the system operates in continuous flow mode, and the outlet end of the ceramic membrane assembly 26 is connected to the inlet end of the second peristaltic pump 9. After being filtered by the ceramic membrane assembly 26, the treated effluent is discharged under the suction action of the second peristaltic pump 9. The ceramic membrane assembly 26 plays a role in solid-liquid separation, preventing light particles from being lost with the effluent.

[0039] It also includes a level controller and a water level monitoring probe 3, which is connected to a level controller 5. The level controller 5 is connected to a first peristaltic pump 4. When the level controller and the water level monitoring probe 3 detects that the liquid level is lower than the set value, the level controller 5 controls the first peristaltic pump 4 to start water intake, thereby achieving automatic liquid level control.

[0040] As an optional implementation, a vacuum pressure gauge 7 is connected between the outlet end of the ceramic membrane module 26 and the inlet end of the second peristaltic pump 9.

[0041] A vacuum pressure gauge 7 is connected between the outlet end of the ceramic membrane module 26 and the inlet end of the second peristaltic pump 9. The vacuum pressure gauge 7 is used to monitor the vacuum pressure of the pipeline between the ceramic membrane module 26 and the second peristaltic pump 9 in real time. When the pressure rises abnormally, it indicates that the ceramic membrane module 26 may be contaminated and clogged, and timely cleaning and maintenance are required.

[0042] As an alternative implementation, when the partition assembly 10 is composed of long partitions 15-2, the inlet end of the second peristaltic pump 9 is connected to the bottom side of the upper reaction chamber 12 through the outlet 18.

[0043] When the partition assembly 10 consists of long partitions 15-2, the system operates in batch mode. The inlet of the second peristaltic pump 9 is connected to the bottom side of the upper reaction chamber 12 through the outlet 18. In batch mode, the treated wastewater is directly discharged into the effluent tank 17 through the outlet 18, without passing through the ceramic membrane assembly 26, simplifying the drainage path and making it suitable for batch operation conditions that do not require membrane separation.

[0044] Specifically, the present invention provides a rapid cultivation system for multiple types of photoparticles for high-salt wastewater treatment, including an inlet tank 1, a photoparticle reaction tank 11, an outlet tank 17, and a photoparticle collection tank 19. The photoparticle reaction tank 11 is connected to the inlet tank 1, the outlet tank 17, and the photoparticle collection tank 19 through a conveying component and a control component.

[0045] The photoparticle reaction chamber 11 includes an upper reaction chamber 12, a lower reaction chamber 13, and an aeration chamber 25. The bottom of the upper reaction chamber 12 and the top of the lower reaction chamber 13 are connected by a flange seal, and the upper reaction chamber 12 and the lower reaction chamber 13 are connected. The bottom of the lower reaction chamber 13 and the top of the aeration chamber 25 are fixedly connected, and the lower reaction chamber 13 and the aeration chamber 25 are connected. The inlet of the upper reaction chamber 12 is connected to the inlet tank 1, the outlet 18 of the upper reaction chamber 12 is connected to the outlet tank 17, and the lower reaction chamber 13 is connected to the photoparticle collection box 19 through the algae discharge port 20.

[0046] The photoparticle reaction chamber 11 contains two sets of variable and detachable partition assemblies 10. The two partition assemblies 10 cooperate with the upper reaction chamber 12 of the photoparticle reaction chamber 11 to form a middle rising chamber 28 and two side falling chambers 27. The two end faces of the two partition assemblies 10 are pluggably connected to the inner side wall of the upper reaction chamber 12 of the photoparticle reaction chamber 11. The rising chamber 28 is connected to the two falling chambers 27 through the top of the two partition assemblies 10. The bottom ends of the rising chamber 28 and the two falling chambers 27 are connected to the lower reaction chamber 13 of the photoparticle reaction chamber 11. The separator assembly 10 has two configurations. When the system adopts continuous flow operation mode, the separator assembly 10 adopts configuration one, which consists of short separators 15-1 and ceramic membrane assembly 26, with the pore size of ceramic membrane assembly 26 being 10μm. When the system adopts batch operation mode, the separator assembly 10 adopts configuration two, which consists of long separators 15-2. The connection end between the light particle reaction box 11 and the aeration chamber 25 is cylindrical and consists of a cup mouth 29 and a cup cover 30. The outer wall of the cup mouth 29 and the inner wall of the cup cover 30 are tightened by threads, and a certain unthreaded space is left between the cup mouth 29 and the cup cover 30 for placing the microporous aeration plate 24.

[0047] The aeration chamber 25 and the cup cover 30 are connected to the gas flow meter 31 and the aeration pump 14 through pipelines.

[0048] The water inlet tank 1 is connected to the photoparticle reaction chamber 11 through the water inlet pipe 2. When the partition assembly 10 adopts the first type, the water inlet tank 1 is equipped with a liquid level controller 5, a liquid level controller water level monitoring probe 3 and a first peristaltic pump 4. When the partition assembly 10 adopts the second type, only the first peristaltic pump 4 is installed on the water inlet tank 1.

[0049] The photoparticle reaction chamber 11 is connected to the water outlet tank 17 via the water outlet pipe 6. When the partition assembly 10 adopts the first type, the end of the pipe of the ceramic membrane assembly 26 is connected to the water outlet tank 17. A vacuum pressure gauge 7, a time relay 8, and a second peristaltic pump 9 are sequentially installed on the water outlet pipe 6 along the flow direction. When the partition assembly 10 adopts the second type, the water outlet 18 on the photoparticle reaction chamber 11 is connected to the water outlet tank 17 via the water outlet pipe 6. Only the second peristaltic pump 9 is installed on the water outlet pipe 6.

[0050] The second peristaltic pump 9 is connected to a time relay 8, and the time ratio for controlling the switching on and off of the second peristaltic pump 9 is 8 min: 2 min.

[0051] An overflow valve 16 is provided on the upper part of the photoparticle reaction chamber 11. The overflow valve 16 is located above the liquid surface in the photoparticle reaction chamber 11 and is connected to the photoparticle collection chamber 19.

[0052] Two sets of light source plates 21 are symmetrically arranged on the outer wall of the light particle reaction chamber 11. The light source plates 21 are connected to a timer switch 22 to control the light-dark ratio of the light source plates 21 to 12h:12h.

[0053] The usage process is as follows: When the baffle assembly 10 adopts Form 1, when the water level monitoring probe 3 of the liquid level controller detects that the water level in the photoparticle reaction tank 11 is lower than the set water level, the liquid level controller 5 controls the first peristaltic pump 4 to work, and the high-salt wastewater enters the photoparticle reaction tank 11 from the inlet tank 1. The wastewater and mixed algae solution move upward with the aeration airflow in the upflow chamber 28 and flow downward in the downflow chambers 27 on both sides, forming a circulating flow state. In this process, regular, dense, and well-settling photoparticles are gradually formed, and at the same time, the concentration of pollutants in the wastewater is reduced to below the discharge standard. The qualified effluent passes through the ceramic membrane assembly 26 and enters the effluent tank 17 under the suction action of the second peristaltic pump 9. When aeration stops, the photoparticles settle into the lower reaction chamber 13, and some of the photoparticles are discharged into the photoparticle collection tank 19 through the algae discharge port 20.

[0054] When the baffle assembly 10 adopts form two, the high-salt wastewater in the inlet tank 1 enters the photoparticle reaction tank 11 under the suction of the first peristaltic pump 4. The flow pattern of wastewater and mixed algae solution in the photoparticle reaction tank 11 is the same as that in form one. During this process, mature photoparticles are gradually formed, and high-salt wastewater is treated efficiently. The treated wastewater enters the outlet tank 17 through the outlet 18 under the suction of the second peristaltic pump 9. When aeration stops, the photoparticles settle into the lower reaction chamber 13, and some photoparticles are discharged into the photoparticle collection tank 19 through the algae discharge port 20.

[0055] In this embodiment, the partition assembly 10 can be detached and its structure can be changed. When the partition assembly 10 adopts Form 1, the ceramic membrane pore size is preferably 10μm, forming first light particles 32 (hydraulic residence time is 1d, food-to-microbe ratio is 53.6KgBOD5 / (KgMLSS·d)) and second light particles 33 (hydraulic residence time is 1d, food-to-microbe ratio is 28KgBOD5 / (KgMLSS·d)). When the baffle assembly 10 adopts Form 2, it forms the third light particle 34 (hydraulic residence time of 1 day, food-to-microorganism ratio of 41.6 kgBOD5 / (kgMLSS·d)), the fourth light particle 35 (hydraulic residence time of 1 day, food-to-microorganism ratio of 6 kgBOD5 / (kgMLSS·d)), the fifth light particle 36 (hydraulic residence time of 4 days, food-to-microorganism ratio of 35.1 kgBOD5 / (kgMLSS·d)), the sixth light particle 37 (hydraulic residence time of 4 days, food-to-microorganism ratio of 14 kgBOD5 / (kgMLSS·d)), the seventh light particle 38 (hydraulic residence time of 6 days, food-to-microorganism ratio of 27.1 kgBOD5 / (kgMLSS·d)), and the eighth light particle 39 (hydraulic residence time of 6 days, food-to-microorganism ratio of 10 kgBOD5 / (kgMLSS·d)).

[0056] In this embodiment, the vacuum pressure gauge 7 is used to measure the water pipe pressure of the ceramic membrane module 26 and the second peristaltic pump 9, and the time relay 8 controls the switching time ratio of the second peristaltic pump 9 to 8 min: 2 min in order to reduce the contamination of the ceramic membrane module 26.

[0057] In this embodiment, the aeration pump 14 aerates air into the lower reaction chamber 13 and the upper reaction chamber 12 through the aeration chamber 25, and the gas flow meter 31 controls the aeration gas volume to be 300-500 mL / min.

[0058] In this embodiment, an overflow valve 16 is provided on the upper part of the upper reaction chamber 12, which is connected to the light particle collection box 19. The function of the overflow valve 16 is to overflow the mixed algal solution into the light particle collection box 19 when the system malfunctions. Therefore, the overflow valve 16 is located above the sewage and does not affect normal sewage treatment.
