Problems solved by technology

[0003] Due to the existence of the gradient layer, the vertical convection of the water body is prevented, and the harmful gas at the bottom of the pool cannot be released in time. Due to the existence of the temperature field, the decomposition of organic matter at the bottom of the pool is intensified, and the biochemical oxygen consumption is large. Based on the above two reasons, the Pond bottom water rapidly deteriorating
[0004] my country's coastline is 18,000 kilometers long. At present, the land mariculture area is 3 million mu, and the offshore aquaculture water area is more than one million mu. If there is heavy rain, tens of thousands of mu or even millions of mu of seawater ponds will instantly become unsaturated solar ponds. Due to the gradient effect in the pond Sudden occurrence will bring significant economic losses to regional marine aquaculture production

Embodiment 1

[0016] Such as figure 1 As shown, the bottom water pump 2 is installed inside the pond 1. When the gradient appears in the pond, the pump starts to work under the action of the automatic control system to make the upper and lower water in the pond convect and mix until zero gradient is achieved. The direction of the arrow in the figure is the direction of water convection.

Embodiment 2

[0018] Such as figure 2 As shown, a well 3 is drilled on the side of the pond 1, and the well water is pumped into the pond. The water at the bottom of the pond infiltrates into the well through underground infiltration, and the uniform mixing of the bottom water body and the surface water body of the pond is completed by continuously pumping groundwater until zero gradient is achieved. . The direction of the arrow in the figure is the direction of water convection.

Embodiment 3

[0020] Such as image 3 As shown, several ponds 1 are connected in series, connected from end to end, and forced closed circuit circulation is realized under the action of the water pump, so that the water in each pond is convected and mixed until zero gradient is realized. Simultaneously, drill a well 3 at the edge of the pond, pump water from the well to supplement the water level of the pond, and form convection and mixing with the pond. The direction of the arrow in the figure is the direction of water flow.

[0021] If the environment permits, industrialized turbot farming and pond prawn farming can be combined to operate, which can save energy, reduce costs, and achieve double harvests for zero-gradient ponds and sheds.

Abstract

The invention discloses a gradient operation method of an unsaturated solar pond, which comprises a solar pond. The method is as follows: by separately adopting the technologies of up spraying, infiltration or subcritical flow or the free combination of the three technologies, unexpected pond gradient effect which is formed by precipitation is destroyed rapidly, thus avoiding that major economic losses are brought to the sea farming owning to unexpected pond gradient effect in coastal areas.

Description

technical field [0001] The invention relates to a zero-gradient operation technology of an unsaturated solar pond, in particular to a method for restraining the negative effects of the unsaturated solar pond to realize healthy cultivation of objects in water with a salt gradient, and belongs to the field of solar aquaculture research. Background technique [0002] In summer and autumn, after heavy rains, shrimp ponds in coastal areas will experience sudden floating heads, which can lead to explosive death in severe cases; sea cucumbers in seawater ponds can be poisoned and diseased overnight! And freshwater ponds and seawater pools in greenhouses will not have similar phenomena. What is the reason? Through on-site inspection and naked experience in the thunderstorm, it was found that the salt gradient layer and temperature field were generated in the pond. [0003] Due to the existence of the gradient layer, the vertical convection of the water body is prevented, and the ha...
