Seawater recirculating aquaculture system

Abstract

The invention relates to a seawater recirculating aquaculture system and belongs to the field of seawater aquaculture. The seawater recirculating aquaculture system can treat and reuse aquaculture water for solving the problem that seawater aquaculture and land breeding contaminate surrounding water environments. The system comprises an automatically controlled microfiltration unit, a low level pool, an integrated biological filtration tank, a protein skimmer, a channel type ultraviolet sterilizer, a cold and heat exchanger and an oxygen dissolution device which are connected sequentially. The automatically controlled microfiltration unit and a pipe oxygen dissolution device are respectively connected to a fish pond. The low level pool is provided with a circulating pump for pumping the water to the integrated biological filtration tank. The protein skimmer is matched with an ozone generator. The seawater recirculating aquaculture system can circulate and reuse water in an offshore land-based breeding pool to achieve the effect of water-saving, energy-saving, environment-friendly and pollution-free healthy breeding.

Description

technical field [0001] The invention relates to the field of mariculture. Background technique [0002] At present, most of the seawater factory culture is open-flowing, and the seawater along the coast of my country is generally subjected to different degrees of industrialization. [0003] Pollution from agriculture and excessive aquaculture in shallow seas, poor water quality, serious disease spread, and some methods such as adding feed during the stocking process will aggravate changes in the water quality of the aquaculture water, so it will inevitably pollute the ecological environment of the sea area, while land aquaculture exists. The regular discharge of aquaculture water also wastes water resources and changes the surrounding water environment. Contents of the invention [0004] The object of the present invention is to provide a seawater circulating aquaculture system capable of treating and reusing the aquaculture water. [0005] The present invention is reali...
