Current industrial circulating water cultivating system the problem is that；There is no the cultivation pair of suitable market terminal price
As because energy consumption cost and operating cost are too high；Besides infrastructure equipment investment is too high, and general farm bears not
It rises；Third is exactly more demanding to managerial and technical staff, and practical farm's peopleware is relatively low, is extremely difficult to require；4th
It is exactly that industrial circulating water cultivating can usually be cultivated with the four seasons, and practical efficiency is not high, most times only less than half
It is running.
The applicant with regard to all multiple-units of the water process of sea water and fresh water industrial circulating water cultivating system made research and
Exploitation, and many achievements are achieved, such as: a kind of aquaculture organisms quality purifying device for water, 2017110397622；A kind of leaching
Do not have a formula water purifying device, 2017200816254；A kind of aquaculture original position filter method and device, 2017112650841；
A kind of ultra violet sterilizer 2017207258507；A kind of fixed aquaculture organisms quality purifying device for water,
2017214126377；A kind of aquaculture organisms quality purifying device for water 2017214126201；Then how system applies this Shen
The device asked someone, obtaining better effect is that applicant and inventor consider the problems of.
Therefore, indoor industrial type of aquaculture field at present, there is two kinds of extreme cases: or be exactly to be filled greatly with arranging greatly
Mode solves the problems, such as that high-density breeding brings water quality inferiority, but energy consumption is high, and water resource waste is big, cost increase, and is not inconsistent
Cyclization guaranteed request；It is exactly indoor industrially circulating water cultivation mode, capital expenditure scale is big, and technical requirements are high, and operation is multiple
It is miscellaneous, the disadvantages of operating cost is higher, earth-free gas.
Utility model content
The utility model aim is that the technology for the water pollution for solving existing sea water and fresh water industrial circulating water cultivating system is asked
Topic, the utility model use a kind of energy conservation and environmental protection circular water treating system and technology, solve previous industrial circulating water cultivating
System or the higher disadvantage of batch production noncirculating water cultivating system energy consumption, operating cost, the especially discharge of water pollution solve
Problem of the water discharge of artificial sea water batch production water cultivation to pollution and the damage of the salinization of soil.
Technical solution adopted by the utility model: sea water and fresh water industrial aquaculture system circulation water treatment system, is included in
The water circulation system and water treatment system that aquaculture pond adjoiner is equipped with, water circulation system include that aquaculture pond bottom is equipped with pipeline for water flow
Water treatment system is led to, water treatment system includes filter element, biological processing unit, disinfection and sterilization unit, and being equipped with pump will water outlet
It send to each aquaculture pond shunt conduit.General approach, which is that the water outlet of disinfection and sterilization unit is sent by the power pumped to each aquaculture pond, to be shunted
The potential energy of pipeline, especially increase water send water to each aquaculture pond shunt conduit
Water flow is led to water treatment system using gravity flow pipeline (i.e. channel) by pipeline, is subject to gas band by liquid level difference or again
Water makees supplement power, and the semi-floating in water is contained the lossless transport such as biological waste；Filter element, biological processing unit, also
Using gravity flow channel, only the water outlet after biological processing unit pumps disinfection and sterilization unit, and disinfection and sterilization unit is by pumping
