Description

Technical Field

[0001] The invention belongs to the technical field of lake heavy metal pollution control, and more specifically, relates to an ecological floating boat device and method for removing heavy metals from water bodies. Background Art

[0002] With the rapid development of industry, lakes are increasingly polluted by organic matter, heavy metal nutrients, etc. Among lake pollution, heavy metals are difficult to degrade, easy to accumulate and highly toxic, which can not only directly poison aquatic organisms and the environment, but also indirectly harm human health through biological enrichment in the food chain.

[0003] Heavy metal pollutants are polluted from external sources and enter lakes through the hydrological cycle. Some of them are exposed in the water body, and some of them gradually accumulate in the sediments in the water body over time, turning into endogenous pollution that is more difficult to control.

[0004] Since the heavy metal content in lake water is much lower than its concentration in sediment, most of the current research on the prevention and control of heavy metal pollution in lakes in my country focuses on dredging and restoration of sludge (sediment), while less attention is paid to the control of heavy metal ions in lake water.

[0005] Traditional heavy metal treatment methods include chemical methods, physical and chemical methods, and biological adsorption methods, all of which have certain limitations in the treatment of heavy metals in lakes. For example, the Chinese patent with publication number CN 215516722 U discloses a heavy metal removal device for water bodies used for river management, which specifically discloses: first, the inlet of the water inlet pipe is set below the water surface, and water is pumped into the treatment box through a one-way valve by a water pump; the motor is started to drive the stirring rod to rotate, and the water entering the treatment box is fully stirred and dispersed to ensure that the water can be fully in contact with the heavy metal adsorption pad to achieve a full removal effect of heavy metals; after full removal, it is tested by a water quality detector; after passing the test, the valve is opened and discharged back into the river, ensuring the water purification effect, and at the same time, the heavy metal removal effect of the device can be more intuitively displayed.

[0006] However, the hull lacks a cruise system and is not convenient to use; the amount of water treated through the pumping, stirring, testing and discharge processes is small; the adsorption material of the device is a heavy metal adsorption pad, and powdered adsorption materials are not suitable for use; there are great restrictions on the adsorption material in actual use, and the developability, degree of automation and energy utilization of the entire device are not high; in actual applications, the device consumes a lot of adsorption materials for water bodies with large water volumes such as lakes and reservoirs, the adsorption capacity is limited, the environmental protection is relatively poor and the labor cost is high.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Among the existing technologies, if the endogenous heavy metal pollution in lakes cannot be solved in a short period of time and the exogenous pollution is effectively controlled, the heavy metal pollution in water bodies will continue to exist for a long time. Moreover, water bodies are more closely related to aquatic organisms and humans. Traditional heavy metal treatment methods include chemical methods, physical and chemical methods, and biological adsorption methods, but they all have certain limitations in the treatment of heavy metals in lakes.

[0026] To solve the above technical problems, please refer to Figure 1-9 As shown, an embodiment of the present invention provides an ecological floating boat device for removing heavy metals from water bodies, the ecological floating boat device comprising an aquatic mobile platform 1, a power propeller 2, a self-cruising module component 3, a heavy metal ion removal component 4 and a control system, wherein: The power propeller 2 is installed at the bottom of the water mobile platform 1; the self-cruising module assembly 3 is installed on the water mobile platform 1, and the self-cruising module assembly 3 is electrically connected to the power propeller 2; the heavy metal ion removal assembly 4 includes an acrylic square groove 41, an ecological filler 42 and a micro diaphragm water pump 43, the acrylic square groove 41 is arranged on the water mobile platform 1, the ecological filler 42 is filled in the acrylic square groove 41, the micro diaphragm water pump 43 is installed between the acrylic square groove 41 and the water mobile platform 1, and the micro diaphragm water pump 43 is suitable for pumping water from the lake into the acrylic square groove 41, and pumping it back to the lake after filtering by the ecological filler 42; the control system is electrically connected to the power propeller 2 and the self-cruising module assembly 3.

[0027] Considering the different distribution of heavy metal ions in different water bodies, the navigation route and water adsorption location are set by the self-cruise module component 3, and the micro-diaphragm water pump 43 is used to pump water into the acrylic square groove 41 for layer-by-layer purification. The heavy metal ions are adsorbed by the ecological filler 42, and the water body is shaken to promote the adsorption reaction. Finally, the reacted water is discharged back into the lake. The entire treatment process has no secondary pollution, and the treatment process is ecological and environmentally friendly, realizing efficient, green, economical and intelligent in-situ remediation of heavy metal pollution in lake waters.

[0028] In addition, the ecological floating boat device can arbitrarily adjust the depth of its absorption of lake water, which is convenient for treating various heavy metal ions at different depths of the water body and has strong flexibility.

[0029] Compared with traditional pure physical and chemical methods, the materials used in this ecological floating device are less expensive, suitable for adsorbing water bodies with various concentrations of heavy metal ions, and powered by solar green energy, and no other pollution is generated during use; compared with some existing biological control methods such as ecological floating islands or underwater forests, the ecological filler 42 has a better adsorption effect on heavy metal ions and can improve the utilization rate of aquatic plants in heavy metal control.

[0030] For further information, see Figure 1 , 2 As shown in Figures 3 and 7, the water mobile platform 1 includes a membrane-sealed buoy 11, a fixed structure 12 and a shell 13. A plurality of membrane-sealed buoys 11 are evenly distributed at the bottom of the fixed structure 12. The fixed structure 12 is connected to the upper surface of the membrane-sealed buoy 11. The shell 13 is connected to the fixed structure 12. The membrane-sealed buoys 11 are symmetrically distributed on both sides of the bottom of the fixed structure 12.

[0031] Preferably, six sealing buoys are provided, and each sealing buoy is made of ultra-high density sealing film. Three sealing buoys are symmetrically arranged on both sides of the fixed structure 12, which not only have good buoyancy but also can control the draft depth; the outer shell 13 is designed to be a structural shape that is convenient for reducing resistance, and the fixed structure 12 is made of stainless steel.

[0032] For further information, see Fig. 9 As shown, the self-cruise module assembly 3 includes a GPS locator 31, a data transmission module 32 and a remote controller 33, wherein the GPS locator 31 is installed on the fixed structure 12, the data transmission module 32 is electrically connected to the GPS locator 31, and the remote controller 33 and the GPS locator 31 are both wirelessly connected to the control system.

[0033] Preferably, the GPS locator 31 in this embodiment is provided with a single chip microcomputer, which is set through the single chip microcomputer program and collects the position of the water mobile platform 1, sends the relevant position information to the control system through the data transmission module 32, and performs positioning cruising through the remote control 33.

[0034] For further information, see Figure 3 , 4 As shown in , 6, the acrylic square tank 41 includes a pressure water tank 411, a first filter tank 412 and a second filter tank 413 which are stacked and connected in sequence from top to bottom. A water inlet 4111 is provided on one side of the pressure water tank 411, and a water outlet 4112 is provided on the other side. The water suction port 431 of the micro diaphragm water pump 43 is located below the sealing membrane float 11, and the water outlet of the micro diaphragm water pump 43 is connected to the water inlet 4111 of the pressure water tank 411 to pump water into the pressure water tank 411.

[0035] Therefore, the acrylic square tank 41 is composed of three layers of filter tanks with different functions, wherein the first layer (the top layer) is a pressure water tank 411, and the adsorption time of heavy metal ions is controlled by controlling the water volume of the pressure water tank 411; the first filter tank 412 is an adsorption layer, wherein partitions with different apertures are arranged in the first filter tank 412, so as to facilitate effective adsorption and filtration treatment of water containing heavy metals; similarly, the second filter tank 413 is also an adsorption layer, and multiple layers of vertical partitions are installed in the second filter tank 413, and the holes of the multiple layers of vertical partitions along the water flow direction are reduced successively, so that filtering can be performed step by step.

[0036] For further information, see Figure 5 As shown, the first filter tank 412 includes a first bottom plate 4121, a first side plate 4122, a first partition plate 4123 and a first perforated plate 4124, wherein: The first side plate 4122 is arranged around the first bottom plate 4121, and the first partition plate 4123 and the first perforated plate 4124 are vertically separated and connected inside the first bottom plate 4121 and the first side plate 4122, a plurality of first partition plates 4123 are evenly distributed on the first bottom plate 4121 along the length direction of the first bottom plate 4121, a plurality of first perforated plates 4124 are evenly distributed on the first bottom plate 4121 along the width direction of the first bottom plate 4121, and each first perforated plate 4124 is evenly distributed with first filter holes.

[0037] The first filter tank 412 in this embodiment is composed of a first bottom plate 4121 and a first side plate 4122 to form a water holding space, in which a plurality of first perforated plates 4124 are arranged along the direction of water flow, and the holes of the plurality of first perforated plates 4124 are successively reduced along the direction of water flow, which is conducive to the gradual filtering and adsorption of heavy metal ions.

[0038] For further information, see Figure 5 As shown, the second filter tank 413 includes a second bottom plate 4131, a second side plate 4132, a second partition plate 4133 and a second perforated plate 4134. The second side plate 4132 is arranged around the second bottom plate 4131. The second partition plate 4133 and the second perforated plate 4134 are vertically separated and connected inside the second bottom plate 4131 and the second side plate 4132. A number of second partition plates 4133 are evenly distributed on the second bottom plate 4131 along the length direction of the second bottom plate 4131. A number of second perforated plates 4134 are evenly distributed on the second bottom plate 4131 along the width direction of the second bottom plate 4131, and each second perforated plate 4134 is evenly distributed with second filter holes. The second side plate 4132 is also provided with a drain outlet 4135 for discharging filtered heavy metal-removed water.

[0039] Similarly, the water filtered step by step in the first filter tank 412 naturally flows into the second filter tank 413. The second filter tank 413 is composed of a second bottom plate 4131 and a second side plate 4132 to form a water holding space. A plurality of second perforated plates 4134 are arranged in the water holding space along the direction of water flow, and the holes of the plurality of second perforated plates 4134 along the direction of water flow are also reduced successively, which is conducive to the gradual filtering and adsorption of heavy metal ions.

[0040] Furthermore, in the embodiment of the present invention, pebbles, gravel and plant powder are sequentially filled in the separation space between the first partition plate 4123 and the first perforated plate 4124 in the first filter tank 412 along the water flow direction.

[0041] It should be noted here that plant powder refers to aquatic plants that grow in water and have a certain ability to remove heavy metal ions. After being harvested, simply dried and ground, the aquatic plants can be used to remove heavy metal ions from water bodies, and the adsorption effect will be much higher than that of directly planted aquatic plants.

[0042] Secondly, this kind of aquatic plant has a wide source and can be used directly from natural water bodies, which is consistent with the current aquatic plant planting and decontamination methods.

[0043] Furthermore, the preparation method of plant powder is simple and consumes little energy. Heavy metals can be extracted from the material after adsorption by plant powder, and the extracted material is also easy to degrade.

[0044] Finally, the adsorption of plant powder is specific. For example, in the laboratory, the adsorption effect of Elodea powder on Cd (II) is 200 micrograms per gram, and that of Zn (II) is 5 micrograms per gram. Because of its specificity, the proportion can be adjusted according to the water conditions, and its efficiency and effect are better, pollution-free and low-cost.

[0045] Thus, the sewage flows from the pressure water tank 411 to the first filter tank 412 of the second layer, first passes through pebbles and gravel to remove large pollutants, and then flows into the second filter tank 413 of the third layer after being adsorbed by plant powder.

[0046] Furthermore, in the embodiment of the present invention, the second filter tank 413 is filled with plant powder, pebbles, gravel and activated carbon in sequence in the separation space between the second partition plate 4133 and the second perforated plate 4134 along the water flow direction.

[0047] Therefore, in the third-layer heavy metal adsorption tank, the water body is adsorbed by the plant powder, and then a small amount of leaked large-particle plant powder material is removed through pebbles, gravel, etc., and finally the activated carbon adsorbs the pigments, odors, etc. in the water body.

[0048] It should be particularly noted that, in order to prevent the filler from leaking out, fluffy cotton is also laid in the second filter tank 413 .

[0049] Furthermore, in an embodiment of the present invention, the ecological floating boat device for removing heavy metals from water bodies also includes a solar power supply component 5, which includes a solar panel 51, a battery 52, a remote control switch 53, a timer 54 and a photoelectric controller 55. The solar panel 51 is installed on the outer shell 13, the battery 52 is installed on the acrylic square groove 41, the timer 54 and the photoelectric controller 55 are installed on the micro diaphragm water pump 43, the solar panel 51 is electrically connected to the battery 52, and the remote control switch 53 is wirelessly connected to the timer 54 and the photoelectric controller 55 respectively.

[0050] See also Fig. 9 As shown, specifically in the specific embodiment of the present invention, the solar power supply component 5 is composed of two 100W solar panels 51, a battery 52, a remote control switch 53, a timer 54 and a photoelectric controller 55, wherein the solar energy collected by the solar panel 51 is converted into electrical energy and stored in the battery 52, and the micro diaphragm water pump 43 is provided with a timer 54 and a photoelectric controller 55 for controlling the operation and running time of the micro diaphragm water pump 43. Considering the convenience of operation and the working conditions of the ecological floating device, the remote control switch 53 is wirelessly connected with the timer 54 and the photoelectric controller 55 respectively.

[0051] The storage battery 52 can also provide power for the entire hull, such as the switch control of the timer 54 and the power supply of the remote control switch 53, etc.

[0052] See also Fig.10 As shown, an embodiment of the present invention further provides a method for removing heavy metals from water bodies, using the ecological floating boat device for removing heavy metals from water bodies as described above, the method comprising the steps of: Step S 100 : The control system controls the power propeller 2 to work, and the power propeller 2 drives the water mobile platform 1 to change the adsorption point in the water body. The power propeller 2 automatically cruises according to the route and stay time set by the control system, and the data transmission module 32 transmits the position and direction of the water mobile platform 1 to the control system in real time; Step S 200 : The control system controls the water inlet 431 of the micro-diaphragm water pump 43 to extract heavy metal wastewater at a certain depth in the water body according to a set length; Step S 300 : The micro-diaphragm water pump 43 is started and operated by the remote control switch 53 and the timer 54, and the micro-diaphragm water pump 43 pumps water to the pressure water tank 411; Step S 400 : After the heavy metal wastewater is adsorbed by the first filter tank 412 and the second filter tank 413 in sequence, the heavy metal-free water body after adsorption is discharged back into the lake.
