Description

Technical Field

[0001] This utility model relates to the field of cyanobacteria treatment equipment, and in particular to a cyanobacteria collection and flocculation device. Background Technology

[0002] Cyanobacteria are a group of large, single-celled prokaryotes with a long evolutionary history, capable of oxygen-producing photosynthesis. They convert carbon dioxide into oxygen through photosynthesis, providing an important oxygen resource for the entire ecosystem. At the same time, cyanobacteria can also absorb large amounts of carbon dioxide, helping to combat climate change. In addition, cyanobacteria play a vital role in rock weathering, soil formation, and the ecological balance of aquatic bodies. Cyanobacteria collection and flocculation devices are mainly used to collect and treat cyanobacteria in water bodies. Through flocculation, the cyanobacteria are aggregated and separated into solid and liquid components, thereby purifying the water quality. Cyanobacteria collection and flocculation devices have broad application prospects in water treatment, environmental protection, and aquaculture, and can play an important role, especially in treating water bodies polluted by cyanobacteria.

[0003] Existing cyanobacteria collection and flocculation devices often cannot precisely control the amount of flocculant introduced during the treatment of cyanobacteria based on the actual situation of the algae, which can easily lead to incomplete or excessive flocculation. Furthermore, when sucking up cyanobacteria from the lake, it is usually necessary to constantly adjust the position of the algae absorber, which makes it impossible to concentrate the algae for collection, resulting in low treatment efficiency.

[0004] Therefore, to address the problems of incomplete or excessive flocculation and low algae absorption efficiency caused by the inability of existing cyanobacterial collection and flocculation devices to precisely control the amount of flocculant, a cyanobacterial collection and flocculation device with a cyanobacterial collector can be designed. This device can precisely control the amount of flocculant according to different flocculation requirements, resulting in better flocculation and less waste of flocculant. Furthermore, by setting up the cyanobacterial collector, pressure can be used to concentrate and collect the cyanobacterial during the absorption process before introducing it into the flocculation device, making the absorption more thorough and the treatment effect better. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Cyanobacteria, also known as blue-green algae or blue bacteria, are single-celled prokaryotes that can produce energy through photosynthesis and have lived on Earth for approximately 3.5 to 3.3 billion years.

[0022] Morphological characteristics

[0023] Cellular structure: Cyanobacteria do not have a true nucleus and organelles. Circular filamentous DNA aggregates in the center of the cell to form a nucleus. There is no nuclear membrane or nucleolus. The inner layer of the cell wall is cellulose, and the outer layer is pectin. The cell wall is often covered with a gelatinous coating or sheath.

[0024] Pigments and photosynthetic products: The cells contain photosynthetic pigments such as chlorophyll α, β-carotene, xanthophyll and bifidus, but do not contain chloroplasts. The assimilation products of photosynthesis are converted into storage substances such as cyanobacterial starch.

[0025] Algal morphology: Cyanobacteria have various morphologies, including single-celled bodies, colonies, and filamentous bodies. Some single-celled bodies become colonies because daughter cells are embedded in the gelatinized mother cell wall after cell division. Filamentous bodies are formed by repeated cell division along the same division plane and the daughter cells connecting with each other.

[0026] Main hazards

[0027] Polluting water sources: The proliferation of cyanobacteria can lead to water quality deterioration, reduce dissolved oxygen in the water, and disrupt the ecological balance. Toxic substances produced by the decomposition of cyanobacteria, such as microcystin, can pollute water sources. Long-term consumption of polluted water may damage organs such as the liver and kidneys.

[0028] Food poisoning: Toxins in cyanobacteria can enter the human body through the food chain, causing food poisoning. They are also toxic to the liver, and in severe cases may lead to liver damage and liver failure.

[0029] Impact on aquatic biodiversity: The massive proliferation of cyanobacteria worsens conditions such as ventilation, light, and oxygen deficiency in the water, hinders the photosynthesis of algae, reduces the living space of fish, and leads to the death of plankton, filamentous algae, and phytoplankton, resulting in a sharp decline in aquatic biodiversity.

[0030] Main value

[0031] Improving soil fertility: Many cyanobacteria, such as Anabaena, contain nitrogenase, which can directly fix nitrogen biologically, thereby improving soil fertility and increasing crop yield.

[0032] Food and nutritional supplements: Some cyanobacteria can be used as food, such as black moss, common nodule algae, and spirulina. Spirulina is a common nutritional food.

[0033] Biochemical raw materials: By genetically engineering cyanobacteria to produce pre-chemicals such as butanediol used in the manufacture of fuels and plastics, it is possible to produce biochemical raw materials to replace fossil fuels.

[0034] A cyanobacteria collection and flocculation device is used to treat water containing cyanobacteria. It uses flocculation to aggregate cyanobacteria into larger particles or clusters, making them easier to separate and collect. It is an effective tool for controlling cyanobacterial blooms and purifying water bodies.

[0035] Mechanism of action: By utilizing the interaction of the flocculant with the surface charge of cyanobacteria, or through adsorption bridging, the cyanobacterial cells are made to aggregate, just like building "bridges" between the cyanobacterial cells, allowing them to change from a dispersed individual state into a larger aggregate, thereby changing the suspension state of the cyanobacteria in the water, making it easier for them to settle or be filtered and collected.

[0036] Blue-green algae collection and flocculation devices can effectively remove blue-green algae from water bodies, improve water quality, and prevent environmental problems and ecological hazards caused by excessive blue-green algae growth. However, some problems often occur during actual use. Below are some common problems and their causes: 1. Device clogging: Clogging may occur during operation, affecting the normal operation of the device and the efficiency of blue-green algae collection. Cause: This may be due to excessively high blue-green algae concentration, causing the internal filter or pipes to be clogged by blue-green algae and its accompanying impurities. In addition, unreasonable device design or untimely maintenance can also lead to clogging. 2. Low collection efficiency: The device's blue-green algae collection efficiency is not high and cannot meet actual needs. Cause: This may be due to poor flocculation effect, failing to effectively aggregate and collect blue-green algae. Simultaneously, environmental factors such as water flow rate, temperature, and pH value may also affect the flocculation effect of blue-green algae, thus affecting collection efficiency. 3. Equipment failure: Malfunctions may occur during operation of the blue-green algae collection and flocculation device, such as motor damage or sensor malfunction. Causes: Equipment failure may be due to inherent quality issues with the equipment itself, wear and tear from prolonged operation, improper maintenance, or improper operation. Furthermore, harsh working environments (such as high temperature, high humidity, and corrosion) can also accelerate equipment damage. 4. High Energy Consumption: The cyanobacteria collection and flocculation device consumes a high amount of energy during operation, increasing operating costs. Causes: This may be due to unreasonable device design or improper operating parameter settings. For example, excessive motor power, prolonged operating time, or excessive flocculant usage can all lead to increased energy consumption.

[0037] Currently, various types of cyanobacteria collection and flocculation devices are available on the market, designed to effectively remove cyanobacteria from water bodies, improve water quality, and prevent environmental problems and ecological hazards caused by excessive cyanobacteria growth. Below are some common cyanobacteria collection and flocculation devices: 1. Foam Scum Collector: This device includes a barrel-shaped collection system, an auxiliary power system, and a floating system. The barrel-shaped collection system is placed below the water surface, using a submersible pump and water supply pipeline to discharge water, causing floating debris such as cyanobacteria to be intercepted and collected by the barrel-shaped filter screen. Problems: Voltage fluctuations may cause unstable equipment operation, resulting in water waste or low collection efficiency. 2. Mechanized Salvage Equipment: This type of equipment typically includes large ship-type salvage platforms and fixed water salvage platforms, which directly salvage cyanobacteria mechanically. Problems: The equipment cost is high, and the efficiency for salvaging cyanobacteria in large areas of water may be low. It also requires a significant investment of manpower and resources. 3. Automatic Blue-Green Algae Collection Device: This device uses water pressure generated by a pump drawing water into a filter mechanism to cause blue-green algae to adhere to the filter screen. A fan then removes the water from the algae, and finally, the algae sludge is bagged. Problems: The device's structure and maintenance may be relatively complex, and its adaptability to different aquatic environments may require further adjustment and optimization. 4. Mobile Algae Bloom High-Efficiency Salvage and Dehydration Integrated Treatment Vessel: This vessel combines salvage and dehydration functions, using onboard equipment to salvage blue-green algae and dehydrate it. Problems: The equipment cost is high, and it may not be suitable for small bodies of water or shallow areas. It also requires professional operators. 5. Semi-Automatic / Fully Automatic Salvage Vessels: Semi-automatic salvage vessels collect blue-green algae through a front collection port. After primary filtration, a pump draws in the algae-rich water for storage. Fully automatic salvage vessels use an algae suction device to draw in the algae, which is then filtered by a treatment device to obtain algae slurry. Problems: Semi-automatic dredging vessels may require more manual operation, resulting in relatively low efficiency; while fully automatic dredging vessels are highly efficient, their equipment and maintenance costs are also higher. 6. Cyanobacteria Containment and Collection Device: This device uses connecting arms and sliding arms to adhere to both sides of the river channel, confining cyanobacteria within the channel and preventing backflow. Problems: Installation and commissioning of the device may require time and costs, and its applicability may be limited in complex aquatic environments. Currently, there are various types of cyanobacteria collection and flocculation devices on the market, each with different working principles and applicable scenarios, but all also have certain problems and challenges. When selecting and using such devices, a comprehensive consideration of factors such as the specific aquatic environment, the degree of cyanobacteria pollution, and economic costs is necessary.

A water pump component for introducing cyanobacteria from the lake into the cylinder 1 is provided on the left side of the cylinder 1. The water pump component and the cylinder 1 are interconnected through the first conduit 5, which is fixedly connected to the upper left side of the cylinder 1. The first conduit 5 and the water pump component are detachably connected by bolts and nuts. An electrical box 4 for power supply and remote connection with a remote terminal is provided on the left side of the water pump component. The electrical box 4 is connected to the water pump... The components are electrically connected by wires. The front end of the cylinder 1 is equipped with a cyanobacteria collector 7 for collecting cyanobacteria in the lake. The lower end of the cyanobacteria collector 7 is fixedly installed with four sets of inserts 8 for inserting into the lake bottom to support the cyanobacteria collector 7. The right end of the water pump assembly is detachably installed with a second conduit 6 for sucking cyanobacteria from the cyanobacteria collector 7. The end of the second conduit 6 away from the water pump assembly extends into the cyanobacteria collector 7. The front end of the cylinder 1 is fixedly installed with a ladder 9 for easy climbing to the top to operate the flocculant introduction assembly. The lower inner side of the cylinder 1 is fixedly installed with a filter plate for filtering cyanobacteria. The right end of the cylinder 1 is fixedly installed near the upper part of the filter plate with a waste algae discharge pipe 10 for discharging waste algae. The right end of the cylinder 1 is fixedly installed near the bottom with a purified water discharge pipe 11 for discharging purified water.

[0039] Please see Figure 3 In this embodiment, the flocculant introduction assembly includes a flocculant storage tank 201, a guide pipe 202, a flow meter 203, a pressure controller 204, a sealing cap 205, and a guide block 206. A guide pipe 202 for introducing flocculant into the cylinder 1 is fixedly installed near the bottom of the front end of the flocculant storage tank 201. A control valve for controlling the inflow and outflow of flocculant is provided on the outside of the guide pipe 202. A flow meter 203 for precisely controlling the flocculant flow rate is fixedly installed on the upper end of the control valve on the outside of the guide pipe 202. A pressure controller 204 for controlling the hydraulic pressure is fixedly installed on the upper part of the front end of the flocculant storage tank 201. A sealing cap 205 for opening and closing is provided at the upper end of the flocculant storage tank 201. A guide block 206 for facilitating the opening and closing of the sealing cap 205 is fixedly connected to the middle of the right end of the sealing cap 205. The pressure controller 204 is model LY810, and the flow meter 203 is model XALD-DN50.

[0040] Please see Figure 4In this embodiment, the water pump assembly includes a pump body 301, a first connecting pipe 302, a second connecting pipe 303, a support column 304, and a support base 305. The upper right side of the pump body 301 is fixedly equipped with a first connecting pipe 302 for detachable connection with the first conduit 5. The right end of the pump body 301 is fixedly equipped with a second connecting pipe 303 for detachable connection with the second conduit 6. The sides of both the first connecting pipe 302 and the second connecting pipe 303 are provided with four sets of connecting holes for detachable connection with the first conduit 5 and the second conduit 6. The lower end of the pump body 301 is symmetrically equipped with two sets of support columns 304 for support. The lower end of the support column 304 is fixedly connected with a support base 305 for increasing support stability. The upper corners of the support base 305 are provided with four sets of mounting holes for mounting and fixing the support base 305.

[0041] When working, first install and fix the water pump assembly in the corresponding position through the mounting holes on its support 305, and connect the first conduit 5 and the second conduit 6 to the first connecting pipe 302 and the second connecting pipe 303 of the pump body 301 respectively.

[0042] Then climb up the ladder 9 to the top of the barrel, put an appropriate amount of flocculant into the flocculant storage tank 201 for temporary storage, and close the sealing cap 205.

[0043] Then connect the waste algae discharge pipe 10 and the purified water discharge pipe 11 to the external collection structure respectively;

[0044] Next, the power supply is supplied through the electrical box 4 and the pump body 301 is controlled to work. The blue algae in the lake is sucked into the blue algae collector 7 through the second conduit 6 for centralized storage. The algae then enter the pump body 301 through the second conduit 6 and are then introduced into the cylinder 1 through the first conduit 5 under the action of the pump body 301.

[0045] Then, by controlling the flow meter 203 and the pressure controller 204, the flocculant is quantitatively and uniformly introduced into the cylinder 1 to react with the liquid containing blue-green algae in the cylinder 1.

[0046] Then, the waste algae that has undergone flocculation treatment is blocked on the filter plate inside the cylinder 1, and the purified water passes through the filter plate and enters the bottom of the cylinder 1.

[0047] Finally, the waste algae and purified water are discharged to their respective locations through the waste algae discharge pipe 10 and the purified water discharge pipe 11 in sequence.

[0048] Through the above steps, by setting up a flocculant collection component with a flow meter 203 and a pressure controller 204, the amount of flocculant can be precisely controlled according to different flocculation requirements, and the flocculant can be evenly introduced into the cylinder 1, thereby improving the flocculation effect and reducing the waste of flocculant. By setting up a cyanobacteria collector 7, the cyanobacteria can be collected together by pressure during the cyanobacteria absorption process and then introduced into the flocculation device, which can make the absorption more thorough and avoid some cyanobacteria settling or dispersing during the absorption process, resulting in better treatment effect. This solves the problem that existing cyanobacteria collection and flocculation devices usually cannot accurately control the amount of flocculant introduced according to the actual situation of cyanobacteria, which easily leads to incomplete or excessive flocculation. In addition, when absorbing cyanobacteria from the lake, it is usually necessary to constantly adjust the position of the algae absorber, which cannot concentrate the cyanobacteria for absorption and has low treatment efficiency.
