Embodiment Construction

[0017] 1. Put the device into the aquaculture water body and observe the water temperature. The surface sleeve can be clean, or can be pre-planted with some algae on the surface and then put into the water.

[0018] 2. When the water temperature is appropriate, power on the device or light, turn on the controller, select the appropriate light intensity, and start working.

[0019] 3. The energy input can be stopped at any time; the device does not need to be taken out of the water; it is only necessary to turn on the energy input when it is used again.

[0020] 4. Under normal circumstances, if the partial bath layer falls off, no maintenance is required. For maintenance, turn off the power or light source, take the device out of the water, detach the luminous body and the surface covering, clean the surface or replace the sleeve, and then assemble to complete the maintenance work. If the surface of the luminous body is mechanically damaged, it should be replaced immediately...

Abstract

The invention provides an underwater microalgae oxygenation device based on a light medium. The shape of the device can be three-dimensional transparent cylinder, plane and grid covered by microalgae. Power or light is input to lighten up the whole structure, and frequency and intensity of illumination can be adjusted according to microalgae species, surface cover thickness and oxygenation rate requirements, so as to realize the purposes of increasing the concentration of dissolved oxygen in water and controlling content of soluble pollutants such as nitrogen and phosphorus in the water. The surface of the device is pre-coated with a single species or a variety of microalgae to form a powerful growth area, and the device also can be put directly in the water for usage under the conditions of low requirements on the microalgae species and no affect on the growth of other animals and plants in the water. Therefore, the device is important in the field of aquiculture culture, especially industrial culture, and can effectively enhance the content of dissolved oxygen in water, reduce contaminant concentration, add shrimp food supplies, prevent the spread of disease and greatly reduce energy consumption.

Description

technical field [0001] The invention belongs to biological green environmental protection and energy-saving technology, biological bait technology, biological water treatment and biological disease prevention technology, and is mainly used in the field of aquaculture. Background technique [0002] With the vigorous development of the aquaculture industry and the rapid increase in the proportion of high-yield and high-density aquaculture, the pollution of the aquaculture water is becoming increasingly serious. Deterioration will cause abnormal changes in nutrients such as nitrogen and phosphorus in the water and produce harmful substances, such as ammonia nitrogen and nitrite, which will cause disease and even death of fish, shrimp and other breeding objects, which seriously hinders the development of my country's aquaculture industry. This phenomenon mainly occurs at night, and the industry has no good solution except to turn on the mechanical aerator day and night. The mech...
