Geomembrane or PVC flipes can be selected in material, and the cost of material is low, and floor space is few；
2, the plane with gradient is formed on the bottom of cultivating water box, and feed residue and fish body excreta can be made with water body
Pump out and be smoothly discharged along the gradient of the plane, instead of traditional pond cultivation because pond bottom it is uneven, it is unfavorable
It is discharged in feed residue and fish body excreta, the formation for greatly reducing the ammonia nitrogen and nitrite in breeding water body is several
Rate is conducive to the purification efficiency for improving water body, and then improves the cultivation density of fish and the survival rate of fish, while can be effective
Avoid pond and surrounding body ecological pollution.
3, the water body in cultivating water box is pumped out with water pump and carries out bottom water, the decontamination of face water, using processing such as biochemical treatments,
To make the water of cultivating water box reach highdensity cultivation standard；
4, it is set by protein separator, Microfilter, biochemical filtration pond in multi-functional pond aquiculture water treatment system
It sets, realizes the purified treatment of the water cycle of entire water treatment system；
5, biochemical filter realize by breeding water body ammonia nitrogen and nitrite decompose, carry out by-pass filtration；By one
The filtered water body of grade, which can for a long time or periodically be flow in the pond for not launching fish, carries out secondary purification, the water cultivated in pond
Grass, vegetables, are absorbed and utilized the rich nutritive materials such as the nitrate in water, and the material absorbings such as nitrogen source in water are purified；
6, recirculated water conveying is carried out only with two water pumps in multi-functional pond aquiculture water treatment system, Microfilter is
Intermittent use just needs to be powered when only cleaning, while wind turbine is used as cultivation and biodegradable oxygen source, system entirety energy consumption
Low, it is low to not only reduce operating cost, and advantageously reduces investment；
7, water pump, Microfilter, Protein Skimmer are placed on the floating platform in pond, floor space is small, without additional
Land infrastructure is carried out, system investment cost is low.
The present invention realizes that breeding water body is isolated with pond waters, with cycle by placing a cultivating water box in pond
The raw processing cultivating system of water dimension carries out double purification by pond is flowed into after cultivation water body purification, then water circulation to cultivation water
In case, realization recycles water resource, and ideal purification effect realizes the dynamic equilibrium of water body, reaches " zero drug " dispensing, cultivation
Waste water zero emission.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every utilization
Equivalent structure transformation made by description of the invention and accompanying drawing content is applied directly or indirectly in other relevant technology necks
