Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a water treatment device. Background Art

[0002] With the rapid expansion of China's aquaculture industry, the proportion of large-scale, high-density aquaculture is also gradually increasing. To achieve higher economic returns, fish farmers often adopt high-density stocking, heavy fertilization and feeding, and the administration of antibiotics and other drugs. Leftover bait and metabolites increase the concentration of water pollutants and leave behind antibiotics that are slow to degrade naturally. Discharging untreated pond effluent directly into the water can cause adverse effects such as eutrophication. Traditional biological treatment methods are inefficient for treating the low carbon-to-nitrogen ratio of fish pond effluent and are unable to degrade antibiotics, resulting in substandard effluent.

[0003] Traditional water treatment systems often utilize shore-based systems, installed on the shore of a fish pond. These systems utilize flotation and microbial principles to pressure-enrich fish pond tailwater, which enters one end of the system. After undergoing a series of treatment processes, the water is discharged from the other end to the fish pond or an external drainage system. However, these traditional water treatment systems are expensive, require shore-based land, and are limited in their water treatment capacity. They also consume significant energy, have complex structures, are difficult to maintain, and suffer from poor restartability, all of which significantly increase treatment costs.

[0026] This utility model water treatment device incorporates a photocatalytic mechanism, a bio-symbiotic mechanism, and a light-emitting mechanism. The photocatalytic body is placed in the pond water via a supporting float. Irradiation of the photocatalyst with external or visible light generates highly oxidizing hydroxyl radicals.

Simultaneously, the supporting float suspends biofouling in the water, allowing more microalgae and microorganisms to attach to the biofouling. Leveraging the synergistic effect of the microalgae and microorganisms, photosynthesis absorbs water pollutants such as total nitrogen, total phosphorus, and COD, providing oxygen as a byproduct. Aerobic bacteria consume this oxygen to nitrify the water, creating a stable food chain from algae and bacteria to existing pond zooplankton, achieving low-cost and high-efficiency operation. Furthermore, the biofouling helps prolong the residence time of the microalgae and microorganisms in the water, enhancing the water's self-purification capacity and improving water treatment efficiency. Furthermore, the provision of a light-emitting mechanism can increase the amount of light in the water at night or during rainy weather, prolonging the photocatalytic oxidation and microalgae photosynthesis process, and improving treatment efficiency. Specifically, the light-emitting element is positioned below the photocatalytic body and aligned with the biofouling, ensuring that the light emitted by the light-emitting element simultaneously illuminates both the photocatalytic body and the biofouling. This structure is simple, rational, and low-cost.

[0027] Therefore, the utility model adopts the cooperation of the photocatalytic mechanism, the biological symbiotic mechanism and the luminous mechanism, which not only has a simple structure and realizes low-carbon and low-cost operation of fish pond aquaculture tail water, but also has high water treatment efficiency.

[0034] This utility model water treatment device incorporates a photocatalytic mechanism, a bio-symbiotic mechanism, and a light-emitting mechanism. The photocatalytic body is placed in the pond water via a supporting float. Irradiation of the photocatalyst with external or visible light generates highly oxidizing hydroxyl radicals. The strong oxidizing properties of hydroxyl radicals convert leftover bait, excrement, and antibiotics in the water into small molecules, selectively converting nitrogen-containing compounds such as ammonia nitrogen into safe and harmless nitrogen gas. Simultaneously, the supporting float suspends biofouling in the water, allowing more microalgae and microorganisms to attach to the biofouling. Leveraging the synergistic effect of the microalgae and microorganisms, photosynthesis absorbs water pollutants such as total nitrogen, total phosphorus, and COD, providing oxygen as a byproduct. Aerobic bacteria consume this oxygen to nitrify the water, creating a stable food chain from algae and bacteria to existing pond zooplankton, achieving low-cost and high-efficiency operation. Furthermore, the biofouling helps prolong the residence time of the microalgae and microorganisms in the water, enhancing the water's self-purification capacity and improving water treatment efficiency. Furthermore, the provision of a light-emitting mechanism can increase the amount of light in the water at night or during rainy weather, prolonging the photocatalytic oxidation and microalgae photosynthesis process, and improving treatment efficiency. Specifically, the light-emitting element is positioned below the photocatalytic body and aligned with the biofouling, ensuring that the light emitted by the light-emitting element simultaneously illuminates both the photocatalytic body and the biofouling. This structure is simple, rational, and low-cost.

Furthermore, the provision of light-transmitting holes enhances the light transmittance of the carrier, allowing sunlight to penetrate the water during the day and allowing light emitted by the luminous element to reach as many locations on the carrier as possible at night, further improving water treatment efficiency.

[0039] More preferably, the carrier is a polygonal carrier. More preferably, the polygonal carrier is a hexagonal carrier, so that the carrier presents a honeycomb shape, which is beneficial to improve the strength of the carrier.

The biological attachment can be fixed to the support body through the hanging holes, so the provision of the hanging holes is conducive to the fixed connection between the biological attachment and the supporting float.

[0046] More preferably, the outer supporting body 221 and the inner supporting body 222 are staggered, which is conducive to the light of the light-emitting body being able to illuminate each biological attachment, i.e., the biological rope filler, and the biological attachments on the inner side will not block the light irradiating the biological attachments on the outer side, thereby ensuring water treatment efficiency.

[0049] The driving mechanism drives the turntable to rotate. During the rotation of the turntable, the toggle block on the turntable will conflict with the first connecting rod and the second connecting rod, causing the first connecting rod and the second connecting rod to move. At the same time, the first connecting rod and the second connecting rod drive the cleaning component to move, causing the cleaning component to reciprocate on the light-emitting body, thereby removing dirt from the surface of the light-emitting body, thereby achieving the purpose of cleaning the light-emitting body.

[0050] More preferably, the cleaning assembly includes a cleaning column 10 and a cleaning member 101 mounted on the cleaning column 10. The cleaning member 101 abuts against the light-emitting element 5. The cleaning member 101 is a sponge and fits over the light-emitting element 5. The cleaning column and the light-emitting element are arranged parallel to each other.
