Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to an algae removal vessel suitable for purifying large areas of water. Background Art

[0002] my country is a country with numerous lakes. In recent years, damage to lake ecosystems and declining water quality have severely weakened the services provided by these ecosystems, even threatening the safety of drinking water sources and the physical and mental health of residents. With the intensification of human activities in river and lake basins, urban water bodies have shifted from clear to turbid, leading to increasing eutrophication and even the emergence of extreme environmental disasters such as black and odorous water bodies and algal blooms, which have attracted increasing attention.

[0003] Currently, there are a wide variety of water environment treatment agents on the market, but most are manually applied and manufactured at the factory, significantly limiting the use of remotely applied or aqueous solutions. Furthermore, the impact of water transparency on water health has become increasingly prominent. Low transparency inhibits plant growth, pushing water bodies from healthy to sub-healthy, and in turn impacting the growth and reproduction of zooplankton, benthic animals, and phytoplankton.

[0004] The invention patent application, publication number CN114477395A, entitled "A composite agent for efficient algae removal and simultaneous phosphorus removal, and a method for simultaneous algae removal and phosphorus removal from water," discloses a composite agent composed of polyaluminum ferric silicate, potassium ferrate, and calcium peroxide, and specifically discloses the preparation and use of the agent. Example 4 discloses an algae cell removal rate of 97% and a total phosphorus removal rate of 81.4%. Although this method can be applied to large water bodies, its use process involves spraying the agent into the water body, with manual stirring by boat during the spraying process, which is complicated and cumbersome to use, and is also unable to specifically treat SS suspended matter.

[0005] The invention patent application with publication number CN112624280A, entitled "A sewage treatment device and application for enhanced coagulation to remove SS and TP", discloses a device capable of achieving continuous automatic treatment. The device has three tanks for coagulation, flocculation and sedimentation, and can remove SS, TP and ammonia nitrogen from water bodies. The removal rates of the three can reach 94%, 80% and 42% respectively. However, the device cannot solve the algal bloom problem in water bodies, and the treatment range is only near the water inlet, and the overall treatment effect on larger areas of water bodies is limited.

[0006] In summary, it is crucial to simultaneously remove eutrophication from large water bodies while restoring water clarity and addressing algal blooms, SS, and nitrogen and phosphorus pollution. This requires a synergistic combination of multiple approaches. Therefore, an algae removal vessel suitable for large-scale water purification is urgently needed to address this problem.

[0027] The nitrogen and phosphorus removal bin 4 is provided with three liquid inlets at its lower portion and three liquid outlets at its upper portion. A filler 41 is provided inside the nitrogen and phosphorus removal bin 4 and contains nitrogen and phosphorus removal functional microorganisms.

[0028] In a preferred embodiment, the algae removal dosing port is provided with an electric switch, which is connected to the signal of the iron ion monitoring probe 22, and is used to maintain the iron ion concentration in the algae removal reaction chamber 2 within a certain range. For reference, the sum of the divalent and trivalent iron ion concentrations of the liquid in the algae removal reaction chamber 2 can generally be 0.1-10 mg / L. Specifically, according to the known technology of the concentration probe, a controller with a display screen can be fixed on the algae removal reaction chamber 2, which receives the signal of the iron ion monitoring probe 22 and judges whether the concentration is within the set threshold range according to the signal. According to the judgment result, the electric switch of the algae removal dosing port is controlled to be turned on for a period of time, or on this basis, weighing quantitative dosing is set. These specific dosing control methods are known technologies, so they are not repeated here.

[0030] Optional, see Figure 1 The algae removal reaction chamber 2 and the SS removal reaction chamber 3 are respectively provided with a stirring device for stirring evenly after adding the medicine.

[0031] In a preferred embodiment, a solar panel 11 is arranged on the hull 1, and the hull 1 is also provided with a waterproof compartment in which a battery and a power assembly 12 are arranged, which are electrically connected to the solar panel 11; liquid pump one 13, liquid pump two 14 and liquid pump three 15 are electrically connected to the battery and the power assembly 12 respectively, wherein the power assembly may include an electric motor to drive a propeller, etc., and the hull 1 can of course also use other power, such as a diesel engine, etc. The three liquid pumps used can also be driven by liquid fuel, but they are not as convenient to control and maintain as electricity. The specific power source can be selected according to the situation; for reference, the battery and the power assembly 12 include a controller electrically connected to the battery, a rudder control mechanism and a propeller control mechanism, and the two control mechanisms are connected to the controller signal, the controller stores a sailing route program, and controls the hull 1 to travel on the surface of the water body to be treated according to the program, so that it can be applied to water environment management in large areas of water. The specific scheme of this automatic sailing is existing technology, so it will not be repeated.

[0032] The method of using the algae removal boat includes using 1 to 3 chambers among the algae removal reaction chamber 2, the SS removal reaction chamber 3, and the nitrogen and phosphorus removal chamber 4 according to the pollution condition of the water body to be purified.

[0033] If the water body to be purified contains algal bloom, SS and nitrogen and phosphorus pollution at the same time, the liquid inlet pipe of liquid pump 13 is extended into the water body to be purified for pumping water, the liquid outlet 1 is connected to liquid pump 2 14 through a pipeline, the liquid outlet 2 is connected to liquid pump 3 15 through a pipeline, and the liquid out of liquid outlet 3 is discharged back to the water body to be purified, realizing the series operation of the three chambers: algae removal reaction chamber 2, SS removal reaction chamber 3 and nitrogen and phosphorus removal chamber 4.

[0034] If the water body to be purified contains only at most two of the following pollutions: algal bloom, SS and nitrogen and phosphorus pollution, the liquid inlet pipes of liquid pump 1 13, liquid pump 2 14 and liquid pump 3 15 are respectively extended into the water body to be purified for pumping water, and the liquid outputs of liquid outlet 1, liquid outlet 2 and liquid outlet 3 are all discharged back to the water body to be purified, realizing the separate operation of the three chambers: algae removal reaction chamber 2, SS removal reaction chamber 3 and nitrogen and phosphorus removal chamber 4, and starting the corresponding liquid pump according to the pollution.

[0035] Since valves are installed before and after each pump, it is convenient to disassemble the connection between the pipe and the pump, which also makes it convenient to apply the hull 1 to different polluted water scenarios.

[0036] Example:

[0037] This example was conducted in the middle reaches of Huangjiatang in Ma'anshan City, a river approximately 10 meters wide and 1.5 meters deep. The experiment took place in early April 2022, when a sudden algal bloom erupted in Huangjiatang, with chlorophyll concentrations reaching a peak of 245 μg / L, total phosphorus 0.45 mg / L, and ammonia nitrogen 4.2 mg / L.

[0038] The hull is made by modifying a small boat. According to the scheme in the above specific implementation method, batteries, solar panels, algae removal chambers, SS removal chambers, nitrogen and phosphorus removal chambers, etc. are added. The YSI probe in the algae removal chamber is installed at the bottom, and the three chambers are used in series.

[0039] Initially, liquid pump 1 is turned on. Due to the poor water quality, the water inlet speed is controlled at a slow rate of 10 cubic meters of water / h. The total iron ion concentration in the liquid in the algae removal chamber is maintained at about 5 mg / L by adding chemicals and stirring. When the water level in the algae removal chamber reaches a certain height, liquid pump 2 is turned on. After water enters the SS removal chamber, flocculant is added. When the water level exceeds the liquid outlet and reaches a certain height, liquid pump 3 is turned on.

[0040] The treated effluent was collected and tested, and it was found that the device can effectively remove more than 80% of algae, more than 75% of SS, and the initial nitrogen and phosphorus removal rate can reach more than 90%. The fillers in the nitrogen and phosphorus removal bin need to be replaced regularly to maintain the ability to efficiently remove nitrogen and phosphorus.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined by the claims.

[0042] Any matters not described in detail in the present invention are well-known technologies to those skilled in the art.
