Description
Technical field
The present invention relates to technical field of aquaculture, be specially the treatment process of a kind of interior circulation fishpond and fishpond cycle water.
Background technology
The flowing water fishpond is common circle, ellipse, rectangle, square corner cut, octagon etc., and different pond, fishpond shapes cut both ways.Circular pond cost is higher, and water exchange and pollution discharging are effective, and unit water yield output is high, but operation is not too convenient, land utilization rate is low; Rectangle pond cost is lower, land utilization rate is high, easy to operate, but water exchange and blowdown are not ideal; Rectangle corner cut and octagon pond cost are lower, the water exchange and blowdown good, easy to operate, but land utilization rate is low.
The fishpond is as the habitat of breeding fish, and in the cultivation of industrialization closed recirculating, its function not to the utmost in this, still has: in time remove the organic collection dirt, discharging pollution functions such as residual bait, ight soil; In time the water body of LDO content is discharged or in time oxygenation; In time the water body with high carbon dioxide, high ammonia-nitrogen content drains into relevant water treatment facilities or in time removes; The function that be convenient to classification, fish for, throw something and feed etc. operates.
The design in fishpond should be reduced to minimum with the current quiet dead zone with cultivation fish body next-door neighbour.In the fishpond of cultivation swimming property fish, combine by moving about of water body flow and fish, form good fluidised form in the territory, the quiet dead zone of current with fish body next-door neighbour, sufficient dissolved oxygen is provided, and the metabolites such as ammonia nitrogen, carbonic acid gas in time are diffused in fishpond waterbody.
Learn according to Fish behavior, fish mainly can be divided into swimming property fish and the end dwelling property fish, and the former likes flowing water, and the latter likes hydrostatic or low speed flowing water.Batch production high density circulating water cultivation is mainly by improving the water body exchange rate, sufficient oxygen, good water quality situation are provided and remove metabolite, realizing the cultivation target of high density, high benefit, ecological, environmental protective; Have the inherent advantages such as happiness flowing water, the streamlined bodily form due to swimming property fish, be very suitable for the object as intensive high density circulating water cultivation
In domestic and international main circulating water cultivation, water treatment technological process has two kinds at present, as figure below, i.e. and centralized technological process and distributing breeding technique flow process.Present centralized technological process accounts for dominant position at home and abroad, and centralized Process of Water Circulating System flow process is generally: fishpond-total return pipe-Microfilter-fluidisation casting bed-degassed-sterilization-oxygenation-feed pipe-fishpond.Be characterized in: flow process be single-threaded, all water bodys all one by one through each unit for treating water, the linear arrangement of each unit for treating water, water treatment zone concentrate, the fishpond is in a row, easy to operate, automaticity is high; Shortcoming is that the water body internal circulating load is large, operation energy consumption is high, operating cost is high, system uses the unit take cover as operation.The distributing technological process is that a fishpond is equipped with a whole set of unit for treating water system or is equipped with the key water processing unit, and a fishpond is only arranged in General System.Be characterized in: there is independent water treatment system in each fishpond, can be before the particulate organic matter fragmentation rapidly and efficiently removal particulate organic matter, independence, flexibility and disease controllability are strong.Shortcoming is: number of devices is many, equipment investment is large, land utilization rate is low, Pipeline arranges complexity, operational administrative inconvenience.
Generally adopt circular fishpond or corner cut fishpond in existing industrial circulating water high-density breeding, exist the shortcomings such as the land area availability is low, effective breeding water body is less, complicated operation is fished in classification, labour intensity is large.
