Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of algae bloom control, and in particular relates to an upflow algae bloom control device and method. Background Art
[0002] Algal blooms not only pollute water bodies, but also threaten human health. The harm of algal toxins has attracted widespread attention. Currently, the technologies for controlling algal blooms are mainly divided into three categories: physical, chemical and biological.
[0003] Among physical methods, although manual salvage can quickly reduce algae, its treatment range is limited and it may accelerate eutrophication of water bodies. Hydraulic dispatching suppresses algae by adjusting water flow, but the engineering cost is high and the environmental impact needs to be carefully assessed. The ultrasonic method is efficient and energy-saving, can destroy key components of algae, is easy to operate and environmentally friendly, but its range of action and energy consumption limit its application and may have an impact on aquatic organisms. The ultraviolet method has the advantages of broad-spectrum sterilization, high treatment efficiency, environmental protection and pollution-free, but its penetration is limited, it is not effective for turbid water bodies, and it has no continuous disinfection ability. Aeration and oxygenation can increase the dissolved oxygen in the water and suppress algae, but it requires a continuous energy supply, has high operating costs, and may sometimes accelerate the aggregation of algae.
[0004] Among chemical methods, the addition of algaecides is effective quickly and is suitable for emergency situations, but it may cause secondary pollution and affect water quality safety. Long-term use may reduce the treatment effect and have a negative impact on the ecosystem. The flocculation sedimentation method precipitates algae by adding flocculants, but the selection and dosage of flocculants must be strictly controlled, and subsequent treatment is complicated.
[0005] Among biological methods, biological manipulation suppresses algae by regulating aquatic communities, has little impact on the environment, and helps restore the balance of the ecosystem, but it is slow to take effect and requires high-level management. Ecological restoration solves eutrophication of water bodies and improves self-purification capacity by planting aquatic plants and releasing beneficial microorganisms, but it is costly and time-consuming, and may face uncertainties such as climate change and biological invasion.
[0006] In summary, existing algae bloom control technologies have their own advantages and disadvantages. Although physical methods can directly reduce algae pollution, cost and environmental impact are limiting factors; chemical methods are quick to take effect, but may have a negative impact on water bodies and ecosystems; biological methods can fundamentally solve the problem, but they are slow to take effect and costly.

DETAILED DESCRIPTION
[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations.
[0024] In the present invention, unless otherwise clearly stipulated and limited, terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.
[0025] like Figure 1 and Figure 2 As shown, an upflow algae bloom treatment device of this embodiment includes a hull 100, and a rotating shaft 101 is vertically provided on both sides of the hull 100. Four support rods 102 are evenly distributed on the circumference of the outer wall of each rotating shaft 101. A treatment module 103 is installed on each support rod 102. The hull 100 is provided with a sensor identification module, a navigation module, a power module 104 and a propulsion module 105. The power module 104 is connected to the propulsion module 105. The power module 104 can use a variety of energy sources, including but not limited to batteries, solar power generation systems or fuel generators, etc., and the power module 104 provides power for the hull and equipment; the propulsion module 105 includes a propeller and a direction controller, etc. The sensor identification module is used to identify the number of algae distribution in the water body, and set a number threshold so that the sensor signal is converted into the range of the hull. The navigation module is used to perform automatic cruising according to the number of algae distribution in the water body identified by the sensor identification module, so that the hull travels in the algae bloom treatment area at a certain speed to achieve automatic cruising treatment, and at the same time, return through the navigation system.
[0026] During the automatic cruising of the hull, the control module 103 can control the algae bloom. During the control, the motor and reducer can drive the shaft 101 to rotate slowly, which can stir the water body and preliminarily destroy the algae structure, so as to facilitate the subsequent work of the control module 103. The control modules 103 on the four support rods on the same shaft 101 have different distances from the outer wall of the shaft 101, which gradually increase in a clockwise direction. The slow rotation of the shaft 101 can also make the control module of the water body more uniform and the control range larger during the rotation process; at the same time, the turbulence effect is better after rotation.
[0027] Specifically, the treatment module 103 includes a guide tube 1 and a shell 2. The guide tube 1 and the shell 2 have the same height. The guide tube 1 is a cylindrical structure that penetrates from top to bottom, and the shell 2 is a structure with a hollow interior. The shell 2 is arranged as a whole at the center of the guide tube 1. The annular space between the inner wall of the guide tube 1 and the outer wall of the shell 2 forms a negative pressure channel. The negative pressure channel is narrow in the middle and wide at both ends, so that the flow velocity of the water body is fastest when passing through the middle of the negative pressure channel. A cutting net 11 is provided in the middle of the negative pressure channel. The outer side of the cutting net 11 is connected to the inner wall of the guide tube 1, and the inner side of the cutting net 11 is connected to the outer wall of the shell 2. The cutting net 11 not only serves to connect the guide tube 1 and the shell 2, but also can cut algae in the water body passing through the negative pressure channel. The cutting net 11 includes a plurality of staggered cutting strips. The cross-section of the cutting strips is as follows: Figure 4 shown.
[0028] A water inlet 3 is provided at the lower end of the shell 2, and a water outlet 4 is provided at the upper end of the shell 2. The water inlet 3 and the water outlet 4 are both evenly distributed small holes, and the small holes are connected to the internal space of the shell 2. During treatment, water flows from bottom to top, flowing in from the water inlet 3 at the lower end and flowing out from the water outlet 4 at the upper end. The height of the shell 2 is generally greater than 60 cm, and the whole is immersed in the water body. The upper end of the shell 2 is generally more than 10 cm away from the water surface.
[0029] The inside of the shell 2 is provided with an aerator 5, a cutting material layer 6 and an agitator 7 from bottom to top, and the aerator 5 and the agitator 7 are fixedly installed in the shell 2. When the aerator 5 is working, a large number of bubbles can be generated, so that a negative pressure is formed in the shell 2, allowing water to enter from the water inlet 3 and flow out from the water outlet 4, and the water near the bottom of the treatment module 103 is exchanged from the lower layer to the upper layer. The negative pressure generated near the bottom of the treatment module 103 exchanges the water containing algae distributed in the upper layer to the lower layer of the water body through the negative pressure channel. The water exchanger function of the treatment module 103 greatly weakens the illumination effect of the algae.
[0030] The agitator 7 is a blade-type agitator. When the agitator 7 is working, it can generate strong stirring turbulence to change the algae structure entering the shell 2 to a certain extent, affecting the aggregation of algae, thereby reducing algae blooms. Specifically, the agitator 7 stirs at a certain speed and time to stir the water in the device to a certain extent. The generated turbulence and turbulence destroy the algae structure in the device and destroy the algae clusters.
[0031] The cutting material layer 6 includes a hollow container and a plurality of cutting units 10 filled in the container. The cutting units 10 are made of plastic and have a shape as shown in FIG. Figure 3 As shown, its surface has multiple ridges to enhance its cutting ability. The cutting material layer 6 can increase the cutting effect of the aerator 5 and the agitator 7 on the water body in the shell 2, breaking up the algae that have gathered into pieces into single or small pieces of algae, and increasing the destructive power of the treatment module 103 on the algae structure.
[0032] In order to prevent algae from adhering to the surface of the cutting monomer 10 and weakening its cutting ability, the cutting material layer 6 is installed in a floating manner in the housing 2. Specifically, the inner wall of the housing 2 is evenly distributed with vertical spiral guide grooves 8, and the guide rods 9 of the cutting material layer 6 are slidably installed in the guide grooves 8. The guide rods 9 are arranged on the outer wall of the container of the cutting material layer 6. When the aerator 5 and the stirrer 7 are working, the stirring turbulence generated by the water body of the housing 2 can drive the guide rods 9 of the cutting material layer 6 to float up and down along the guide grooves 8, so that the cutting monomer 10 keeps moving up and down, making it difficult for algae to adhere to its surface.
[0033] In summary, the control module 103 can change the living environment of algae and destroy the algae structure; the control module 103 can be conveniently installed on the unmanned navigation hull 100, so that the water body containing algae blooms can exchange the algae layer in the upper layer of the water body to the lower layer of the water body (greater than 80 cm) under the action of negative pressure, so that the light effect of the algae is greatly weakened, the living environment of the algae is changed, and the reproduction and breeding of algae is reduced. During this process, the algae are destroyed and cut many times. First, the rotation of the shaft 101 drives the treatment module 103 to rotate and stir the water body, which initially destroys the algae structure. Secondly, the aerator 5 can generate a large number of bubbles when working, so that a negative pressure is formed in the shell 2, allowing the water to enter from the water inlet 3 and flow out from the water outlet 4, and the algae in the water body are cut through the cutting material layer 6; then the agitator 7 can generate strong stirring turbulence when working to further break up the algae structure after passing through the cutting material layer 6; at the same time, the negative pressure generated near the bottom of the treatment module 103 exchanges the water containing algae distributed in the upper layer to the lower layer of the water body through the negative pressure channel, and the cutting net 11 cuts the algae in the water body passing through the negative pressure channel.
[0034] This embodiment also provides an upflow algae bloom control method, which uses the above-mentioned upflow algae bloom control device to perform bloom control.
[0035] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
