Description

Technical Field

[0001] The invention relates to a cruise ship carrying device and a method for purifying a water body, and belongs to the field of water body eutrophication and heavy metal pollution control. Background Art

[0002] Global freshwater resources only account for 2.5% of the total water resources. Rivers and lakes are important water resources, which are closely related to human survival and are the foundation of ecology and the source of civilization. With the rapid development of industry, the excessive nutrient content in rivers and lakes has led to serious eutrophication of water bodies, and the water ecology is facing serious threats. In addition, the intensification of heavy metal pollution in rivers and lakes not only has serious harm to animals and plants in the water and the environment, but also will eventually threaten human health through the enrichment of food chains and food webs. Therefore, the work of heavy metal treatment and improvement of eutrophication of rivers and lakes is urgent.

[0003] Wastewater, waste residue and waste gas discharged during the production process by industries such as mining, smelting, electroplating, instrumentation, coatings, glass, chemicals and agriculture discharge heavy metal elements and their compounds into various water bodies through urban pipe networks, surface runoff, rainfall and other processes in the hydrological cycle, causing heavy metal pollution in water bodies. Heavy metal pollutants enter lakes with the hydrological cycle, mainly in the form of particles, migration and transformation. The process is complex and diverse, including almost all physical, chemical and biochemical processes in water bodies. Most heavy metal elements have multiple valence states, are highly active, can participate in various chemical reactions, and have different chemical stability and toxicity. As environmental conditions change, their morphology and toxicity also change. Heavy metals are easily absorbed, concentrated and enriched by organisms, and can also be amplified step by step through the food chain to reach the level of endangering top organisms. In the process of migration and transformation, under certain conditions, the morphological transformation or phase transfer of heavy metals has a certain reversibility, but heavy metals are non-degradable toxic substances and will not lose their toxicity due to the destruction of the compound structure. Current technology cannot quickly and effectively solve the problem of heavy metal pollution in rivers and lakes in a short period of time, and heavy metal pollution in water bodies will continue to exist for a long time.

[0004] In the aquatic environment, phosphorus mainly appears in three forms: orthophosphate, polyphosphate and organic phosphate. Among them, orthophosphate will present different ionic forms under different pH conditions, including H2PO4 - ,

[0005] HPO4 2- and PO4 3-. Organic phosphates exist in water bodies in the form of organic matter, and they can be gradually converted into orthophosphates through biological oxidation. Orthophosphate is a common form of phosphorus in water bodies, and it is also a form that can be directly absorbed and utilized by plants. However, when excessive phosphorus is discharged into water bodies, it will cause a series of serious problems, the most notable of which is the acceleration of the growth and reproduction of algae, which in turn poses a great threat to the safety of the water environment. This hazard is specifically manifested in multiple aspects: First, the rapid reproduction of algae and other plankton will consume a large amount of dissolved oxygen in the water body, causing the dissolved oxygen content in the water body to drop sharply. This change has caused serious damage to the living environment of aquatic animals and plants. Many aquatic animals and plants are difficult to survive due to lack of oxygen, and eventually decline and die, and may even lead to the extinction of some species. In addition, it will have a negative impact on the development of fisheries. As the survival of aquatic animals and plants is threatened, the foundation on which the aquaculture industry depends is destroyed, resulting in the inability of the aquaculture industry to carry out normal business activities, causing huge economic losses to related industries. Excessive phosphorus will also harm the diversity and stability of organisms in water bodies. Excessive phosphorus will disrupt the original ecological balance, change the structure and function of the aquatic ecosystem, and weaken the self-regulation ability of the ecosystem. Once the water body is polluted by phosphorus, the quality of the water body, which is an important water source for humans, will decline, and the amount of available water will be correspondingly short. After people drink contaminated water, their health will face potential risks, which may cause various diseases and seriously affect human health.

[0006] Therefore, the innovative research and development of heavy metal ion and phosphate pollution control technologies in river and lake waters should receive further attention and importance, which is of great significance for ensuring the safe supply of drinking water for human beings, maintaining the balance and stability of the ecosystem, and promoting the sustainable development of the social economy.

[0007] Traditional methods for controlling heavy metal pollution in water bodies include chemical precipitation, ion exchange, membrane electrolysis, and living biological adsorption. These methods are all limited in controlling heavy metal pollution in rivers and lakes, such as high cost, difficulty in control, subtle effects, and high labor and material resources. For example, chemical precipitation adds chemical precipitants such as hydroxides, sulfides, and carbonates to water bodies containing heavy metals, causing heavy metal ions to react chemically with the precipitants to form insoluble precipitates, which are then separated and removed from the water body. For example, when lime milk is added to cadmium-containing wastewater, cadmium ions react with hydroxide ions to form cadmium hydroxide precipitates. This method is simple to operate and has low cost, but a large amount of sludge may be produced when the amount of precipitant is large, and some heavy metal precipitates may be redissolved due to environmental conditions. At present, my country is still in the initial stage of using biological adsorption technology to control water pollution. For example, in a heavy metal removal project in a water body in Jinan City, the peel-modified three-dimensional mesh heavy metal adsorption membrane and cellulose-modified multi-level porous clay adsorbent developed by the Engineering Research Institute of China Construction Eighth Bureau were applied, and certain results were achieved. However, there are still problems such as limited scope of application, unstable adsorption effect for different water qualities, narrow raw material procurement channels, complex preparation process, and large equipment investment.

[0008] At present, the treatment methods for phosphorus mainly include biological method, ion exchange method, electrochemical method, membrane separation method, artificial wetland method and adsorption method. The chemical method is to use chemical agents to react with phosphorus in the water body to generate water-insoluble precipitation, and then remove phosphorus from the water body by solid-liquid separation. The principle of biological phosphorus removal is mainly that polyphosphate bacteria absorb phosphorus under anaerobic conditions, release phosphorus under aerobic conditions, and achieve phosphorus removal by discharging phosphorus-containing sludge. The principle of ion exchange phosphorus removal is to use materials with ion exchange function to exchange with phosphate. Common materials include natural resins and synthetic resins. The basic principle of the electrochemical method is to use anode materials such as aluminum and iron to electrolyze metal cations, and then precipitate with phosphorus in the water to form metal phosphate salts. The membrane separation method uses a membrane with selective permeability to recover phosphorus. According to the pore size of the membrane, it can be divided into nanofiltration membrane (NF), ultrafiltration membrane (UF) and microfiltration membrane (MF). Artificial wetlands are built and controlled by humans. They are similar to common natural wetlands and are mainly composed of pretreatment systems, water intake systems, and wetland systems. Artificial wetlands remove phosphorus mainly through filler interception, microbial absorption and transformation, and plant absorption.

[0009] In recent years, adsorption has gradually emerged in people's vision. It is considered to be an economical and effective way to remove pollutants. Its principle is to use solid materials with developed pore structures to undergo physical and chemical reactions such as ion exchange, surface precipitation and ligand exchange with heavy metal ions and phosphates in water, thereby achieving the purpose of pollution removal. Adsorbents with good ecological benefits include biochar, activated carbon, plant powder adsorbents, etc.

[0010] Existing methods for treating heavy metals in water environments have high technical requirements and high R&D costs, or may cause secondary pollution:

[0011] (1) The existing chemical method is too expensive, requires a large amount of reagents, and may cause potential harm to the water body. It will also produce a large amount of sludge, causing secondary pollution. The electrochemical method consumes a lot of electricity, has high operating costs, and produces a large amount of precipitation. As the reaction continues, the removal effect will decrease over time. It is not suitable for field operations.

[0012] (2) The emerging membrane separation method in the physical and chemical method is highly efficient and has no secondary pollution, but the filter membrane it uses cannot take into account both low cost and simple manufacturing process. The ion exchange method has the risk of secondary pollution during the treatment process and is easily affected by impurities. It cannot directly deal with heavy metals and eutrophication problems in the water body. It is necessary to pre-treat the water body, the water purification device is relatively complex, and the process is cumbersome. Ion exchange functional materials are expensive, have poor selective removal, and the exchange capacity is affected by many factors, which is not suitable for large-scale application.

[0013] (3) Biological methods have shown many advantages in the process of removing phosphorus and heavy metal ions. However, the key to biological methods is to ensure the survival rate of microorganisms, which places high demands on process operation control. In addition, most of the water bodies treated by them cannot directly meet the national minimum phosphorus emission standards and need to be supplemented by other methods. Therefore, biological process operation control has high requirements and its flexibility and adaptability are insufficient.

[0014] (4) Traditional adsorption methods involve chemical adsorption and physical adsorption. Depending on the adsorption material, biological adsorption is also involved. Many highly efficient adsorbents, such as activated carbon, carbon nanotubes, and certain metal oxides, have complex preparation processes and expensive raw materials, resulting in high production costs for adsorbents. Most adsorbents lack specificity in the adsorption of heavy metal ions and eutrophic substances. While adsorbing target heavy metal ions and eutrophic substances, they may also adsorb other ions or substances in the water body, affecting the adsorption effect on target heavy metals and eutrophic substances. The regeneration process of many adsorbents is not easy. Some physical regeneration methods (such as heating, decompression, etc.) may consume a lot of energy and the regeneration effect is unstable; chemical regeneration methods may use a large amount of chemical reagents, leading to secondary pollution problems. At the same time, they may also damage the structure and performance of the adsorbent and shorten the service life of the adsorbent.

[0015] A Chinese patent with publication number CN 119284058 A discloses an ecological floating boat device and method for removing heavy metals from water bodies, and specifically discloses the following steps: a control system controls the operation of a power propeller, the power propeller drives the water mobile platform to change the adsorption point in the water body, the power propeller automatically cruises according to the route and stay time set by the control system, and the data transmission module transmits the position and direction of the water mobile platform to the control system in real time; the control system controls the water suction port of a micro-diaphragm water pump to extract heavy metal sewage at a certain depth in the water body according to a set length; the startup and running time of the micro-diaphragm water pump are controlled by a remote control switch and a timer, and the micro-diaphragm water pump pumps water to a pressure water tank; the heavy metal sewage is adsorbed by the first filter tank and the second filter tank in turn, and the de-heavy metal water body after adsorption is discharged back into the river or lake.

[0016] However, the hull is large and expensive, and is more suitable for pollution control in scientific research projects or large water bodies such as those with complex pollution distribution. In actual applications, the device is greatly limited in its application to scenarios such as parks, lakes, and urban rivers where pollution control investment is limited, the volume is small, and the pollution distribution is relatively stable. Summary of the invention

[0017] In view of the shortcomings of the above-mentioned technologies, the present invention proposes a cruise ship-mounted device for purifying water bodies, which can be used with solid adsorbents such as activated carbon and biochar. Compared with traditional methods, this device has lower pollution removal costs and is suitable for adsorbing heavy metal ions of various concentrations and eutrophic water bodies. The kinetic energy generated by the movement of facilities such as park cruise ships on the surface of the water body is used to drive the water body and the adsorbent in the device to undergo an adsorption reaction. Compared with biological control methods such as artificial wetlands or plant floating islands and floating beds, plant powders have better adsorption effects on heavy metal ions and eutrophic substances. The device can be carried on dynamic or static facilities on the surface or around water bodies such as park cruise ships. It is easy and convenient to disassemble, has high flexibility, and low operability. Tourists can participate in water pollution control while playing.

[0018] The technical solution of the present invention is as follows: a device for purifying a water body on a pleasure boat, the device comprising a hull fixing module, a structural support module, a power water intake module, a water purification module, a tail flow baffle, and an EPS material filling module;

[0019] The hull fixing module is installed with the carried hull, and the bottom of the hull fixing module is connected with the structure supporting module. The structure supporting module is provided with two modules which are respectively located on both sides of the hull. A power water inlet module is installed at the front end of each structure supporting module, and a water purification module is arranged inside each structure supporting module. A tail flow baffle is installed at the rear end of each structure supporting module, and the EPS material filling module is located in the gap of each structure supporting module.

[0020] Further, the hull fixing module includes more than one retractable bracket and more than one fixture, each retractable bracket includes a cross bar and two bottom bars, the tops of the two bottom bars are respectively connected to the two ends of the cross bar, the bottoms of the two bottom bars are installed on the fixture, the fixture is connected to the structural support module, and the cross bar is fixed on the hull;

[0021] Furthermore, the structural support module includes a streamlined shell and an aluminum alloy bracket. Two aluminum alloy brackets are provided and are respectively installed inside the streamlined shell. The fixer is fixed on the aluminum alloy bracket. The power water inlet module includes a variable angle countercurrent baffle and a water inlet. The water inlet is a multi-porous water inlet opened at the front end of the streamlined shell. The variable angle countercurrent baffle is obliquely installed at the front end of the streamlined shell. The water purification module includes a power water storage tank, a primary filter tank, a plant powder adsorption tank, a secondary filter tank and a tail treatment tank. Each tank is arranged from the front end of the streamlined shell to the rear end of the streamlined shell in sequence, and an acrylic baffle is provided between each tank. The acrylic baffle is provided with multiple holes for water flow to pass through. The tail flow baffle is installed at the rear end of the streamlined shell in a pull-out manner, wherein the tail treatment tank is filled with activated carbon and fluffy cotton, the primary filter tank and the secondary filter tank are filled with PP, PE, and HDPE particles of different sizes, the plant powder adsorption tank is filled with a packaged plant powder adsorbent, and the tail flow baffle is installed at the rear end of the streamlined shell in a pull-out manner.

[0022] Furthermore, a filter screen may be provided at the water inlet of the power water inlet module to screen out macromolecular substances or aquatic organisms.

[0023] Furthermore, the fixer is an annular square belt welded with a steel structure.

[0024] Furthermore, a method for removing phosphate and heavy metal ions from water by using a cruise ship-mounted device for purifying water is characterized in that the specific steps are as follows:

[0025] (1) First, sampling the corresponding water body to detect the concentration of pollutants in the water body, and based on the water environment conditions of the applied water body, a suitable mixed plant powder adsorbent is prepared;

[0026] (2) The size of the carrying device, the retractable bracket, the variable angle countercurrent baffle, and the amount of plant powder adsorbent are adjusted according to the size of the water area, the size of the boat and the power source of the hull. The carrying device is adjusted to the optimal height, that is, when the cruise ship is stationary, the multi-hole water inlet of the power water inlet module is higher than the horizontal plane and the entire device has no vertical force on the hull. The process of installing the fixture on the aluminum alloy bracket can be manually installed or mechanically installed; the acrylic plate uses a low-density and high-hardness 1mm thickness, and is equipped with a high-hardness and low-mass aluminum alloy bracket that can bear the weight of an adult. A foot pedal can be designed to facilitate the user to smoothly enter the cabin through the carrying device;

[0027] (3) After the user reaches the cabin, the tail baffle of the carrying device is pulled out before starting. When the cruise ship is stationary, the multi-hole water inlet of the power water inlet module of the carrying device is higher than the horizontal surface and water cannot enter the carrying device. At the same time, the tail baffle is closed. At this time, the detachable powder carrying tank is in a completely closed state;

[0028] (4) When the cruise ship is moving, the kinetic energy of the ship drives the sewage to the height of the porous water inlet with the help of the variable angle countercurrent baffle to achieve the purpose of dynamic water inlet. After the sewage flows into the carrying device, the sewage is stored in the power water storage tank to a higher water level due to the small aperture of the primary filter tank; then the sewage flows into the primary filter tank. The PP, PE, and HDPE materials of different particle sizes in the primary filter tank can remove large-volume pollutants. The sewage continues to flow into the plant powder adsorption tank, where the plant powder adsorbent realizes the adsorption of heavy metal ions and phosphorus; the water after adsorption enters the secondary filter tank, and a small part of the leaked adsorbent is intercepted here; the activated carbon and fluffy cotton filled in the tail treatment tank can absorb pigments and odors in the water body, prevent the filler from leaking, and purify the outflowing water to avoid secondary pollution;

[0029] (5) According to actual usage needs, open the water purification module every one or two weeks, replace the plant powder adsorbent and ecological filler, and perform inspection and maintenance. After completion, repeat the above steps to achieve the purpose of water purification.

[0030] The beneficial effects of the present invention are:

[0031] (1) The present invention utilizes the kinetic energy generated by facilities such as park cruise ships when they move in the water to achieve unidirectional flow of sewage, effectively promoting the reaction between the water and the plant powder adsorbent, without relying on additional electricity resources, significantly reducing operating costs and avoiding the risk of secondary pollution.

[0032] (2) The device of the present invention adopts a modular design, and the components are tightly connected and easy to disassemble, which greatly facilitates regular maintenance and overhaul. The detachable design makes it easy and quick to replace the plant powder adsorbent and ecological filler, further reducing the difficulty and cost of maintenance.

[0033] (3) The use of retractable brackets not only ensures the stability and durability of the device, but also enables the device to adapt to different water environments and ship types, demonstrating a high degree of flexibility.

[0034] (4) Experimental data show that the device equipped with the best matching plant powder adsorbent can effectively absorb Zn 2+ 、Cd 2+ , Cu 2+ The adsorption efficiency of heavy metal ions such as PO4 is over 95%. 2-The adsorption efficiency also reaches 90%. While removing heavy metal ions, the device can also effectively remove odors and filter large particles of impurities, maximizing ecological and economic benefits, and there is no risk of secondary water pollution in the whole process.

[0035] (5) This device can prepare different types of plant powder mixed adsorbents for heavy metal pollution in different water bodies, so that the device can maintain a high removal efficiency for heavy metal pollution in different water bodies.

[0036] (6) By setting up a power water inlet module and a tail baffle, the water flow is managed in a one-way manner. When the device is stationary in the water body, the water level cannot reach the height of the power water inlet module and the tail baffle is closed. At this time, the device does not operate. Before the device moves, the tail baffle is opened. When moving, the variable angle countercurrent baffle lifts the water to the height of the water inlet under the action of power. After the water flows in, the particles filled in the primary filter tank have a small pore size, so the water flow is first stored in the power water storage tank. After the power water storage tank is full, the water flow is managed in a one-way manner under the action of the water level difference between the power water inlet and the tank. Reduce the tediousness of manual operation; at the same time, an integrated water quality monitoring sensor can be installed to monitor water quality changes in real time, and the treatment strategy can be adjusted based on data feedback, thereby improving treatment efficiency.

[0037] (7) The present invention mainly targets plant powder adsorbents, which are low in cost and free of secondary pollution. They can significantly reduce the cost of treatment and achieve ecological and environmental protection goals. Moreover, under different water flow rates and temperature conditions, the heavy metal ion removal efficiency is stable and has wide applicability.

[0038] (8) The filling of EPS material provides sufficient buoyancy for the entire carrying device without adding extra burden to the hull, allowing ordinary people to participate in the water purification work while ensuring safety, convenience and aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

After the sewage flows into the carrying device, the sewage is stored in the power water storage tank (8) to a higher water level due to the small aperture of the primary filter tank (9); then the sewage flows into the primary filter tank (9), and the PP, PE, and HDPE materials of different particle sizes in the primary filter tank (9) can remove large-volume pollutants. The sewage continues to flow into the plant powder adsorption tank (10), and the plant powder adsorbent achieves the adsorption of heavy metal ions and phosphorus in the plant powder adsorption tank (10); the water after adsorption enters the secondary filter tank (11), and a small part of the leaked adsorbent is intercepted there; the activated carbon and fluffy cotton filled in the tail treatment tank (12) can absorb pigments and odors in the water body, prevent the filler from leaking, and purify the outflowing water to avoid secondary pollution; (6) According to actual usage needs, open the water purification module every one or two weeks, replace the plant powder adsorbent and ecological filler, and perform inspection and maintenance. After completion, repeat the above steps to achieve the purpose of water purification.
