Abstract
This patent discloses a water treatment method for recirculating aquaculture. The method includes the following steps: step A, culture water discharged from a culture pond passes through filter equipment to remove water-insoluble dirt; step B, the culture water passes through a protein separation device to remove soluble protein in water; step C, the culture water passes through purification equipment for removal of harmful substances in water and sterilization; step D, the culture water passes through reduction equipment for supplementing of trace elements; step E, the culture water passes through first-stage fine filtration equipment to remove small impurities and flocculent precipitates in water; step F, the culture water passes through second-stage fine filtration equipment to remove excess cations and strong oxides in water; step G, the culture water passes through temperature control equipment for water temperature adjustment; and step H, the culture water passes through oxygen increasing equipment for oxygen increasing, and then enters the culture pond. The method and equipment can purify and reduce culture water, kill pathogens in the water body, reduce the content of ammonia nitrogen and nitrites, and remove harmful substances in the water body.
Description
technical field [0001] The invention relates to the field of purification and reduction of water for circulating aquaculture, and is especially suitable for circulating aquaculture of various fresh water, brackish water and seawater organisms, fresh water and seawater recirculation aquaculture, freshwater and seawater ornamental organism recirculation aquaculture, seafood and freshwater Circulating water treatment for holding, seafood and freshwater transportation. Background technique [0002] At present, natural water bodies are seriously polluted, aquaculture is seriously affected, and the water used for aquaculture must be treated before it can be used. Aquaculture water treatment mainly adopts: physical technology, such as a large number of water changes, aeration, filtration, precipitation, adsorption, air flotation, etc.; chemical technology, such as flocculation, neutralization, complexation, redox, ozone disinfection, etc.; biological technology, Such as adding or ...
