The application discloses a water bottom reoxygenation device, and relates to the technical field of water bottom oxygenation, which comprises a water pumping device, a floating container, a water conveying pipe and a weight. The floating container is located on the water surface, the first end of the water pumping device is located below the water surface, the second end of the water pumping device is located at the upper end of the floating container, the water pumping device conveys the water below the water surface to the upper end inlet of the floating container, the upper end of the water conveying pipe is connected with the lower end of the floating container, the lower end of the water conveying pipe is fixed with the weight, and the weight is located at the water bottom. The water body surface layer oxygen-rich water can be pumped out and conveyed to the water bottom oxygen-deficient water layer along the water conveying pipe, so that the oxygen content of the target water layer is increased.

The utility model relates to aquatic products breeding equipment technical field discloses an oxygen -increasing equipment for aquaculture, including drive assembly, conical water leaf subassembly and float frame subassembly, spare carry the drive assembly of reduction gearbox and drive motor, reduction gearbox can effectively adjust power output speed, reduce the influence of load fluctuation to power transmission, ensure that conical water leaf subassembly rotates stably, reduce the oxygen -increasing efficiency fluctuation of power instability, prolong the service life of equipment. Conical water leaf subassembly adopts the design of conical bucket body and circumferential distribution blade, can effectively reduce the resistance, is not easy to reduce the speed because of load, simultaneously, conical bucket body can guide the water flow to form the spiral ascending movement track in the rotation process, expands water body agitating range, can promote the exchange of surface layer oxygen -rich water and deep layer oxygen -deficient water.

The present application belongs to the technical field of water treatment, and relates to an intermittent oxygenation in-situ water quality improvement synchronous algae control device, comprising: a floating platform, a first water tank, a drainage assembly, an aeration assembly, an ultrasonic assembly and a control assembly. The present application intermittently starts the aeration assembly and the ultrasonic assembly through the control assembly, intermittently oxygenates through the aeration assembly, simultaneously sends the algal bloom on the water surface into the first water tank through the outer cylinder and the inner cylinder, and then utilizes the ultrasonic assembly to emit ultrasonic waves to destroy the air bag of the algal bloom, so that the algal bloom loses buoyancy and is discharged into the middle layer of the water body and can sink downward under the action of gravity. On the one hand, in-situ algae control can be performed, and on the other hand, water quality of the water body can be improved through oxygenation to avoid the formation of anoxic water body, so that in-situ water quality improvement and in-situ algae control are simultaneously performed. Not only the operation cost and energy consumption are reduced, but also the algae is reduced and the water quality of the water body is improved, so that the effect of improving the water quality of the lake and reservoir water body is improved, and the safety of taking water from the lake and reservoir is ensured.

An apparatus and method for oxygenating water in ponds, lakes, and seas while simultaneously providing a water massage to a user. The apparatus comprises a submersible frame (1) equipped with a plurality of nozzles (6) that deliver air bubbles or water jets, creating a massaging effect while oxygenating the surrounding water. The frame can be used independently, placed on the lake bottom, or attached to a watercraft or a jetty using a coupling element (16). This invention enables use in diverse environments, including oxygen-depleted waters and those unsuitable for traditional bathing due to low temperatures, parasites, or potentially dangerous aquatic life or flying stinging insects. The apparatus may further include an enclosure for protecting the user from undesirable aquatic life, cold water, or flying insects. The invention addresses the limitations of existing solutions by providing a versatile and convenient way to improve water quality and enhance recreational water activities.

The invention belongs to the technical field of water treatment, and relates to an intermittent oxygenation in-situ water quality improvement synchronous algae control device which comprises a floating platform, a first water tank, a drainage assembly, an aeration assembly, an ultrasonic assembly and a control assembly. The aeration assembly and the ultrasonic assembly are intermittently started through the control assembly, algae blooms on the water surface are fed into the first water tank through the outer cylinder and the inner cylinder while intermittent oxygenation is conducted through the aeration assembly, and then ultrasonic waves emitted by the ultrasonic assembly are utilized to damage an air bag of the algae blooms, so that the algae blooms lose buoyancy; after being discharged into the middle layer of a water body, the algae can be settled downwards under the action of gravity, on one hand, in-situ algae control can be performed, on the other hand, water quality of the water body can be improved through oxygenation, an anoxic water body is prevented from being formed, in-situ water quality improvement and in-situ algae control are performed at the same time, the operation cost and energy consumption are reduced, algae are reduced, and the water quality of the water body is improved; therefore, the lake and reservoir water quality improvement effect is improved, and the water taking safety of the lake and reservoir is guaranteed.

The invention discloses a deepwater reservoir antibiotic resistance gene transmission risk control device and method. The device comprises a solar heat collection-power generation floating island platform, a thermosyphon-gas stripping combined circulator and an intelligent monitoring and feedback system. The floating island platform supplies power through a photovoltaic panel and drives a solar heat exchanger, and the combined type circulator utilizes a plurality of vertical heat exchange pipelines and combines a thermosyphon effect (density difference is formed by solar heating) and an air stripping effect (bottom bubble plume oxygenation) to forcibly mix bottom layer anoxic water and surface layer oxygen-enriched water, crack thermal stratification and lift dissolved oxygen; the intelligent monitoring system monitors water quality and resistance gene abundance in real time through a multi-parameter sensor, and dynamically adjusts aeration rate and circulation intensity. According to the method, the triple targets of thermal stratification breaking, bottom layer oxygenation and ARGs diffusion inhibition are achieved, the whole process is driven by solar energy, the targeting property is high, the method is suitable for a regulation and storage type drinking water source reservoir, and a green prevention and control scheme is provided for globally preventing and controlling the ARGs pollution risk of the water body.
