It is difficult to meet the cultivation demand of migration fishes.
Invention content
In view of the foregoing defects the prior art has, the present invention proposes a kind of new advection racetrack circulating water cultivation system
System.
The present invention is realized using technical solution below：
A kind of advection racetrack circulating water culture system, including culture zone, water delivery area and sewage diposal area, culture zone include
At least one aquaculture pond, water delivery area include that return water canal, bypass canal and feeder canal, sewage diposal area include Microfilter pond, aeration tank
With at least one biological tank；Aquaculture pond water outlet is connected with return water canal, and return water canal is connected with Microfilter pond and bypass canal, return water canal
Gate is equipped between return water canal and Microfilter pond between bypass canal；Microfilter pond is connected with biological tank, biological tank and aeration
Pond is connected by bypassing canal, and bypass canal end is disposed adjacent with aeration tank, is bypassed and is pumped equipped with plug-flow between canal end and aeration tank
Unit, aeration tank are connected with feeder canal, and feeder canal is connected with aquaculture pond water inlet；Aquaculture pond water outlet is equipped with collection dirt, discharging pollution knot
Structure, Microfilter pond are equipped with Microfilter unit, and biological tank is equipped with filtrate, and biological tank both ends are equipped with filtrate intercept net.
It for the processing mode of breeding pollution waste water is promoted to higher position using elevator pump in the prior art, entered
Specific sewage disposal system is handled.The shortcomings that there are two aspects：1, the hoisting depth of water is higher, and energy consumption is higher；2、
The promotion water of elevator pump is limited by pipeline diameter, to also limit sewage load and sewage treating efficiency.This
The advection racetrack circulating water culture system of invention use plug-flow pump unit, plug-flow pump unit compared with elevator pump, lift compared with
It is low, it is ensured that the energy consumption of system reaches minimum.Plug-flow pump unit can plug-flow big flow water body, can fully improve aquaculture pond
Interior water body self-purification ability simultaneously ensures the velocity flow pattern needed for Fish Survival.The bypass canal being connected with return water canal is arranged in the present invention,
And gate is equipped between return water canal and Microfilter pond between return water canal and bypass canal.When Microfilter goes wrong, is overhauled
When, the closing gate between return water canal and Microfilter pond can be opened the gate between return water canal and bypass canal, water flows into
Enter to bypass canal, after plug-flow pump unit, complete a cycle, water body is in the part without Microfilter, biological tank, it is ensured that
Stable operation in the circulating water culture system short time.Aquaculture pond water outlet is equipped with dirt collection pollution discharge structure, can discharge at regular time and quantity
Pollutant.
Further, the return water canal and feeder canal are arranged in parallel, and aquaculture pond is set between return water canal and feeder canal.
Aquaculture pond is set to the technical solution between return water canal and feeder canal, only need to extend return water canal and feeder canal, you can
More aquaculture ponds are added between return water canal and feeder canal, it can be achieved that the modularization of aquaculture pond extends, it is easy to accomplish cultivating system
Enlarging.
