Water circulation system for adult fish culture pond

Abstract

The invention relates to the field of aquaculture, especially to a water circulation system for an adult fish culture pond. The water circulation system comprises a water-supplement higher-place pond, a biological pond, ultraviolet disinfection equipment, a water body aerator and a culture pond which are connected in order through pipelines and a residual-feed excrement collector, a sieve bend filtering basin and a protein separator which are connected through pipelines from a sewage draining exit of the culture pond. The protein separator is connected with a water inlet of the biological pond through a pump body. An inflow disinfection and oxygenation process formed by the ultraviolet disinfection equipment and the water body aerator and an effluent filtration and purification process formed by the residual-feed excrement collector, the sieve bend filtering basin and the protein separator are arranged between the biological pond and the culture pond. In addition, with a purification function of the biological pond and water supplement of the water-supplement higher-place pond for the biological pond, a complete set of circulation system is formed. That is to say, water resources are saved and utilized, and a growth environment of aquatic products is also guaranteed.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a water circulation system for fish breeding ponds. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and fence farm...

AI Technical Summary

Problems solved by technology

[0003] In high-density intensive culture, the secondary water in the culture pond is not easy to recycle and utilize, resulting in a waste of water resources
