Water environment pollution, disease increase year by year, food safety demand, coastal industry land used squeeze and country advocates energy-saving and emission-reduction equipressure
Power, development have faced a bottleneck, it would be highly desirable to change.
Industrial circulating water cultivating mode is to be handled and be recycling as core feature with breeding water, economize on electricity, water-saving, section
Ground meets circular economy, energy-saving and emission-reduction, the Strategic Demand transformed mode of economic growth that current country proposes.
Key problem in technology in industrial circulating water cultivating be breeding water purified treatment with recycle, that is, establish to protect
Retaining ring border is the closing inner-circulative culture system of basic point, its core technology is water treatment technology, and key technology is biological net
Change.Effect of the metabolin through microorganism is cultivated, the harmful substance nutrient salts in water body are converted into degradation, reaches and purifies water,
Increase breeding efficiency, improve efficiency of feed utilization, realizes zero-emission or combustion with minimal.
Biofilm is that the microorganism (i.e. biomembrane) using apposition growth in certain carrier surfaces carries out at organic sewage
The method of reason, it is the usual way of industrial circulating water cultivating biological cleaning filtering.Biomembrane is by the aerobic of highly dense
The ecosystem of the compositions such as bacterium, anaerobic bacteria, amphimicrobe, fungi, protozoan and algae, the solid dielectric of attachment are known as filtering
Material or carrier.The principle of biofilm is, biomembrane adsorbs attachment water layer organic matter first, by the aerobic bacteria of aerobic layer by its point
Solution enters back into lonely layer and carries out anaerobic digestion, and flowing water layer then washes out the biomembrane of aging to grow new biomembrane, so
Back and forth to achieve the purpose that purify sewage.
Biological flocculation technology (Bio-floc Technology, BFT) is the relatively advanced aquaculture released in recent years
Technology, the technology were put forward for the first time by Israel aquaculture expert Yoram Avnimelech in 1999, and in 2005
Indonesia's success of the test, it refers to by manipulating water nutrition structure, and organic carbonizable substance is added into water body, adjusts water body
In C/N value, stirred in combination with sufficient oxygenation and water body, promote the metabolism breeding of heterotrophicy bacteria in water body, utilize micro- life
Object effect is by the nitrogen-containing pollutants such as ammonia nitrogen in water body degradation removal or is converted to bacterium own biological amount, and passes through bacterium wadding
It congeals into particulate matter to be ingested utilization by cultivated animals, plays maintaining that water environment is stable, reduces quantity of exchanged water, promotes animal immune
Power improves the effects of cultivation survival rate, increase yield and reduction feed coefficient, it is considered as solving aquaculture industry development
Effective substitute technology of the environmental constraints and feed cost that are faced.

Aquatic products circulating water culture system described in any one of 7 based on biological flocculation and biomembrane cultivates early period as biological flocculation training
In the feeding and carrier biofilm biofilm stage, biofiltration area is only opened, the water of culture zone is directly entered through water pump from the second water outlet
Biofiltration area, elastic filler are realized rapid biofilm by intercepting and adhering to biological flocculation and organic granular in cultivation water, are passed through
Water flow after filter returns to culture zone；The middle and later periods is cultivated, as feeding volume constantly increases, culture zone water body floc sedimentation amount reaches certain dense
After degree, settling zone is opened, culture zone water first enters settling zone through the first water outlet and removes extra floc sedimentation and organic large particulate matter
Afterwards, the further purified treatment in biofiltration area is entered back into, water flow after filtering returns to culture zone.
