Water treatment method of circulating water fish culture in factory style

Abstract

The invention discloses a seawater factory-style circulating water fish farming treatment method which comprises, removing the residual bait and excrement from the seawater flowing out of the fish pond through full-automatic conduit pipe filter apparatus, entering foam separate tank from the circulating pump to remove part of the suspended matter and protein, then removing ammonia nitrogen through biological cleaning tank, adjusting water temperature and pH, disinfecting through ultraviolet rays, oxygenation, charging the detected water into the fish pond again, thus completing a circulation.

Description

technical field

[0001] The invention belongs to circulating water fish farming technology, in particular to a factory-like circulating water fish farming water treatment method. Background technique

[0002] Seawater industrial circulating water fish farming uses certain facilities and equipment to continuously recycle the water used for fish farming, thereby not only ensuring high and stable production of commercial fish throughout the year, but also achieving the purpose of saving water, energy and protecting the marine environment. Foreign fishery developed countries (especially Western European countries) have relatively advanced industrial fish farming technology, but their facilities and equipment are expensive and are not suitable for my country's national conditions. However, most of the current seawater factory fish farming in my country is an open-water fish farming model, which consumes a lot of energy, wastes groundwater resources, and causes pollution to the mar...
