Problems solved by technology

At present, there is no safe, cheap, and effective technical solution that can control salt, light, temperature, oxygen, virus, and water quality through the same method, and can use the control of these conditions to simultaneously inhibit algal blooms and enteromorpha. , Spirogyra, or the outbreak of aquatic plants, so as to avoid damage to the growth of aquatic products

Embodiment 1

[0016] Above a 2 mu square breeding pond near the sea, a ceiling support 2 meters above the water surface was built with wooden sticks (as shown in the figure). Transparent fluted, UV-resistant transparent corrugated sheets are installed on the brackets as the backing material for the water-containing roof. When the daytime light intensity is suitable, pump the water from the breeding pond to the roof (process ① in the figure), and then allow the water to flow down naturally at a certain speed on the roof (process ② in the figure). In-situ photosynthesis damping and water quality automatic adjustment composite device on the water surface, by controlling the residence time of water on the roof, the water on the roof can undergo various changes under the light, including but not limited to (that is, process ② in the figure): salt nitrate nitrogen concentration or precipitation; roof transmittance (amount) decreases with the increase of luminous flux (this novel effect is due to ...

Embodiment 2

[0018] For large-area ponds, multiple combinations of units in Embodiment 1 can be constructed in various forms.

Abstract

The invention provides a method for carrying out circulating exchange on saline water in an aquaculture water pond and a photosynthesis damping and water quality automatic adjusting and compounding device constructed above the water pond. The aims of purifying the water quality, oxygenating, killing viruses and bacteria, denitrifying a water body, automatically adjusting the salinity of the water body, preventing from algae bloom storm, enteromorpha storm, spirogyra storm and aquatic plant overgrowth, and guaranteeing the healthy growth of aquatic products are automatically realized by using sunlight.

Description

technical field [0001] The invention belongs to the technical field of water environment control in aquaculture. Background technique [0002] In seawater or freshwater aquaculture, the growth of aquatic products (such as fish, shrimp, crab, shellfish, sea cucumber, etc.) is often affected by algal blooms, Enteromorpha outbreaks, Spirogyra outbreaks, aquatic weeds and aquatic bacteria or viruses, resulting in aquatic products Farming production is severely compromised. Although there are many reported methods, there is no safe, effective and cheap solution. For example, the method of spraying pesticides may kill algae or inhibit aquatic plants in a short time and in a small area, but it may cause damage to the growth of aquatic products. At the same time, the drug effect time is short and the efficiency is low, so it is difficult to work in actual production. Pathogenic bacteria or viruses in long-term culture ponds often develop drug resistance, and it is difficult to hav...
