Process flow of water circulation of culture pond

Abstract

The invention relates to a process flow of water circulation of a culture pond, and belongs to the technical field of aquatic culturing. The process flow of the water circulation of the culture pond comprises the following steps that 1, air feeding hoses are arranged on air exhaust final ends of the bottom of part or all of the culture pond; 2, the other ends of the air feeding hoses are provided with aeration sandstones, and extend into water lifting pipes; 3, floating type biofilters are transversely limited, so as to avoid floating after the culture pond is injected with water; 4, the water is injected into the culture pond until the floating type biofilters float, and high-pressure air is sprayed out of the air exhaust final ends; 5, the air feeding amount in each water lifting pipe is adjusted until the water normally flows of the upper opening of each water lifting pipe, the water flowing out of the water lifting pipes flows into biological felt bins, enters biological filtering material bins through first overflow racks, and flows into the culture pond through second overflow racks; and 6, large contaminants in the biological felt bins are periodically cleaned, or biological felts in the biological felt bins are replaced, and biological filtering material in the biological filtering material bins is periodically replaced.

Description

technical field [0001] The invention relates to a process flow for water circulation in a culture pond, which belongs to the technical field of aquaculture. Background technique [0002] In the existing aquaculture production, the use of mechanical equipment in the aquaculture water body mainly considers mechanical oxygenation and physical water quality control. The main problems are: 1. In order to control the water quality of the aquaculture water and pursue high yield, the production units blindly increase the number and power of aeration machines, resulting in an increase in energy consumption in aquaculture production; The accumulation of state nitrogen and the effective removal of three-state nitrogen are mainly solved by changing water, resulting in the extensive use of water resources and the pollution of external source water environment by aquaculture discharge water. Contents of the invention [0003] The technical problem to be solved in the present invention ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved in the present invention is: the removal of tri-state nitrogen in existing aquaculture ponds is relatively difficult, and the accumulation of tri-state nitrogen in the pond is generally solved by changing water, thereby causing a large amount of water resources to be used and a large amount of aquaculture water to be discharged , resulting in pollution of the external source water environment
