Bait makes cultivation object maintain best physiology, ecological state always under the conditions of high-density breeding, to reach health and fast fast-growing
It is long, unit of water body yield and quality is improved to greatest extent.After the solid suspension and water of discharge generally go through natural sedimentation separation
It outlet or recycles again.But simple gravity precipitating can not obtain good clean-up effect, often bring to environment
Pollute or cause the exceeded of breeding environment total nitrogen, total phosphorus and suspended matter.
Residual bait and excrement are still the main source of the pollutants such as nitrogen phosphorus in fishes and shrimps pond.The N in artificial bait throwing in input fishes and shrimps pond
It is present in water in the form of particulate form, soluble organic nitrogen, inorganic nitrogen etc..Nitrogen phosphorus revenue and expenditure studies have shown that only 31.89% nitrogen
Be converted into Fish tissue after into body, remaining 52.5% with urine (in the form of ammonia, urea and uric acid), 15.61% with
Excrement enters water body environment after being discharged fish body.Ratio into water body environment phosphorus has then been more than nitrogen, reaches feeding amount
70.2%, show that bait is the main source of culture pond N.P input, accounts for the 68%-92% always inputted and 73%-91%, bait
Only has the biomass that 14%-21% and 7%-10% is converted into fishes and shrimps in material, while containing a large amount of antibiotic etc. in tail water, not
Processed breeding wastewater direct emission, certainly will aggravate the eutrophication of the water bodys such as river and lake, reservoir, and direct circulation reuse can then drop
The water quality of low breeding water body.And China is that one of poor-water country, aquaculture are more to consume water resource again the most in the world
Therefore one of industry carries out the processing of cultivation tail water original position ecological purification and cycling and reutilization equally plays a significant role and meaning.
Cultivation tail water purified treatment in the prior art, it is net that the cultivation tail water of discharge needs to first pass through each pond precipitating
Change.Cultivation tail water purification pond accounts for the 5%-10% of entire cultivating pool area, occupies cultivation land used, and build pond needs
Manpower and material resources are more, higher cost.Each pond every requiring maintenance clean for a period of time, it is also necessary to spend manpower and material resources, increase
Purification cost is added and the purification each pond of tail water requires to stay for some time, the time for needing to purify is long, purification efficiency is low.
And the pollutant residence time is long, and residual bait and excrement can further release ammonia nitrogen and phosphate shadow under the action of anaerobic bacteria
Ring water quality.
