Abstract
Description
Technical Field
[0001] This utility model relates generally to the technical field of water treatment, and more specifically to a water treatment device. Background Technology
[0002] With the rapid urbanization and industrialization in my country in recent years, much domestic sewage and industrial wastewater have not been adequately, scientifically, and effectively treated, leading to increasingly severe water pollution and a more serious water shortage in the country. Residual feed and excrement from traditional open aquaculture (pond and cage culture) models often act as direct sources of pollution, causing large amounts of organic and inorganic matter to directly enter the environment. This results in a series of major problems restricting the sustainable development of aquaculture, including water pollution, disease outbreaks, and compromised hygiene and safety of aquatic products.
[0003] Industrialized recirculating aquaculture systems (RAS) are a modern, highly intensive aquaculture model. With advantages such as low land and water resource requirements, controllable production processes, high yield per unit of water volume, and low waste discharge, they have become the future direction of aquaculture development and a model supported and promoted by Chinese policy. The core of industrialized RAS is the use of a water treatment system to treat pollutants generated in the aquaculture ponds and then recirculate them, ensuring that the water quality meets relevant standards.
[0004] Currently, the decentralized water treatment systems used in industrial recirculating aquaculture systems suffer from problems such as limited space utilization, low energy efficiency, and weak resistance to shock loads, resulting in poor wastewater treatment during the aquaculture process.

[0046] Figure 1A water treatment device according to the present invention is shown. The water treatment device includes a tower body 100, a degassing component 120, a filtration component 130, a biochemical component 140, and an oxygenation component 150. Multiple support plates 101 are provided inside the tower body 100, and the multiple support plates 101 are arranged at intervals along the height direction Z of the tower body 100, thereby forming a structure within the tower body 100 that, from top to bottom along the height direction Z, comprises a degassing chamber 102, a filtration chamber 103, a biochemical chamber 104, and an oxygenation chamber 105.
[0047] A degassing assembly 120 is at least partially disposed in the degassing chamber 102 for removing dissolved carbon dioxide from the water. A filtration assembly 130 is at least partially disposed in the filtration chamber 103 for removing suspended solids from the water. A biological treatment assembly 140 is at least partially disposed in the biological treatment chamber 104 for converting organic nitrogen in the water into nitrates or inorganic nitrogen. An oxygenation assembly 150 is disposed in the oxygenation chamber 105, and an aeration hole (not shown in the figure) is provided at the top of the oxygenation assembly 150, so that the oxygenation assembly 150 sprays oxygen from bottom to top along the height direction Z into the oxygenation chamber 105 and the biological treatment assembly 140.
[0048] The tower body 100 has an inlet 106 at the top that connects to the degassing chamber 102, and an outlet 107 at the bottom that connects to the oxygenation chamber 105. This allows the water entering the tower body 100 through the inlet 106 to be processed sequentially by the degassing component 120, the filtration component 130, the biochemical component 140, and the oxygenation component 150, and finally discharged through the outlet 107.
[0049] According to the water treatment device of this utility model, water enters the tower body 100 through the inlet 106, passes sequentially through the degassing chamber 102, the filtration chamber 103, the biochemical chamber 104, and the oxygenation chamber 105, and is discharged from the outlet 107, thereby achieving water treatment. The tower body 100 integrates the degassing component 120, the filtration component 130, the biochemical component 140, and the oxygenation component 150, resulting in a small footprint, high space utilization, low energy consumption, strong resistance to shock loads, and good wastewater treatment effect.
[0050] In addition, the oxygenation component 150 sprays oxygen from bottom to top along the height direction Z into the oxygenation chamber 105 and the biochemical component 140. This not only oxygenates the water in the oxygenation chamber 105, but also provides dissolved oxygen for the biochemical reaction in the biochemical component 140. Through the nitrification and denitrification reactions of the microorganisms attached to the packing, the organic nitrogen in the water is converted into nitrate or inorganic nitrogen, which can effectively degrade organic matter, ammonia nitrogen and other substances in the water.
[0051] Optionally, the support plate 101 is not a closed plate, but can be a perforated plate, etc., so that water and gas can pass through, and water can be transferred and processed between the components.
[0052] Optionally, the tower body 100 includes a sprayer (not shown in the figure), which is connected to the water inlet 106. The sprayer is arranged in the degassing chamber 102 and located above the degassing component 120, so that the water entering the degassing chamber 102 through the water inlet 106 can be sprayed onto the degassing component 120, thereby increasing the contact area between the water and the degassing component 120 and improving the degassing efficiency. Furthermore, the sprayer can be constructed to form a spiral nozzle, preferably an anti-clogging nozzle, which can form a conical spray surface, thereby improving spraying efficiency and reducing clogging.
[0053] Alternatively, the tower body 100 may be equipped with a water inlet 106 and multiple sprayers. The combined action of multiple spray heads can expand the spraying area of water on the degassing component 120, making it easier to form a water film on the packing and enhance mass transfer efficiency.
[0054] Optionally, refer to Figure 1 The degassing assembly 120 includes a first filler 121 and a first air inlet pipe 122. The first filler 121 is constructed as a multifaceted hollow sphere and is disposed in the degassing chamber 102. The first air inlet pipe 122 is disposed below the first filler 121 along the height direction Z, so that the air introduced through the first air inlet pipe 122 contacts the water film on the surface of the particles of the first filler 121 in the opposite direction, promoting the diffusion and desorption of carbon dioxide in the water, thereby achieving the effect of removing dissolved carbon dioxide from the water. The top of the tower body 100 is provided with an exhaust port 108, which can discharge the air and desorbed carbon dioxide delivered to the degassing chamber 102 by the first air inlet pipe 122.
[0055] Optionally, the first filler 121 is made of polypropylene plastic, which has good corrosion resistance and will not pollute water bodies.
[0056] Optionally, the filter assembly 130 includes filter media 131, which is disposed in the filter chamber 103 for filtering water entering the filter chamber 103 and removing suspended solids, colloids, and other impurities from the water. Filter media 131 can be selected as sponge filter media 131, which has good filtration performance.
[0057] As the filter assembly 130 continues to work, the impurities accumulated in the filter media 131 gradually increase, which will reduce the filtration performance of the filter media 131 and may even pollute the water body, making it difficult to continue treating the water body.
[0058] Furthermore, the tower body 100 also includes a first drain outlet 109, which connects to the filter chamber 103 and is positioned in the upper middle part of the filter media 131 along the height direction Z (located above the middle surface of the filter media 131 along the height direction Z). The filter assembly 130 also includes a second air inlet pipe 132 and a first aeration pipe 133. The second air inlet pipe 132 connects to the first aeration pipe 133, which is positioned below the filter media 131 along the height direction Z, allowing for the use of clean water to clean the filter media 131. Clean water enters the filter media 131 within the filter chamber 103, and high-pressure air from the second air inlet pipe 132 is introduced into the filter media 131 through the first aeration pipe 133, thereby backwashing the filter media 131 and impurities within the filter chamber 103, restoring the filtration performance of the filter media 131. The backwash wastewater can be discharged from the tower body 100 through the first drain outlet 109.
[0059] Optionally, the biochemical component 140 includes a second filler 141 and a supporting filler 142. The second filler 141 is arranged above the supporting filler 142 along the height direction Z, and the particle size of the second filler 141 is smaller than that of the supporting filler 142. When the aeration component 150 injects oxygen into the biochemical chamber 104, the water in the second filler 141 and the supporting filler 142 is aerated, resulting in a stepped dissolved oxygen distribution in the biochemical chamber 104. This provides different concentrations of dissolved oxygen to the microorganisms in the biofilm formed on the surfaces of the fillers (second filler 141 and supporting filler 142) at different heights. The biofilm is composed of various microorganisms that originate from the water and attach to, grow, and reproduce on the surfaces of the fillers (second filler 141 and supporting filler 142), effectively degrading organic matter, ammonia nitrogen, and other pollutants in the water. Specifically, organic nitrogen in water is converted into ammonia nitrogen by microorganisms, ammonia nitrogen is converted into nitrite by ammonia-oxidizing bacteria, nitrite is converted into nitrate by nitrite-oxidizing bacteria, and nitrate is converted into inorganic nitrogen through denitrification.
[0060] Optionally, the second filler 141 is constructed as a combination of volcanic rock particles and activated carbon, and the supporting filler 142 is constructed as volcanic rock particles. This allows the microorganisms to be mainly concentrated in the second filler 141. Since the particle size of the supporting filler 142 is larger than that of the second filler 141, it will not affect the oxygen delivery to the second filler 141 for aeration.
[0061] Furthermore, along the height direction Z from top to bottom, the second filler 141 is arranged in a manner with gradually decreasing particle size, thereby forming a stepped dissolved oxygen distribution within the second filler 141, making the contact between water and oxygen more uniform and the conversion effect better.
[0062] As the biochemical component 140 continues to operate, the number of microorganisms in the second filler 141 and the supporting filler 142 increases, and the suspended matter also increases, which can easily cause pore blockage of the filler (second filler 141 and supporting filler 142) and affect the conversion performance of the biochemical component 140.
[0063] Optionally, the tower body 100 also includes a second drain outlet 110, which is connected to the biochemical chamber 104. The second drain outlet 110 is located in the upper middle part of the second packing material 141 along the height direction Z (located above the middle surface of the second packing material 141 along the height direction Z). The biochemical component 140 also includes a third air inlet pipe 151 and a second aeration pipe 144. The third air inlet pipe 151 is connected to the second aeration pipe 144. The second aeration pipe 144 is located below the supporting packing material 142 along the height direction Z, and can be used with cleaning water to clean the packing materials (second packing material 141 and supporting packing material 142). Clean water enters the packing material (second packing material 141 and supporting packing material 142) in the biochemical chamber 104. High-pressure air connected by the third air inlet pipe 151 is introduced into the packing material (second packing material 141 and supporting packing material 142) through the second aeration pipe 144, thereby backwashing suspended impurities and aged and detached biofilm in the packing material (second packing material 141 and supporting packing material 142) and the filter chamber 103, restoring the biochemical performance of the biochemical component 140. The backwash wastewater can be discharged from the tower body 100 through the second drain outlet 110.
[0064] Optionally, the oxygenation component 150 includes a third air inlet pipe 151 and an aeration disc 152. The third air inlet pipe 151 is connected to oxygen and communicates with the aeration disc 152. Aeration holes are arranged on the top surface of the aeration disc 152, thereby introducing oxygen into the oxygenation chamber 105 and the biological chamber 104, thereby oxygenating the water in the oxygenation chamber 105. The oxygenated water is discharged from the tower body 100 through the outlet 107, and can also aerate the biological chamber 104.
