Specific embodiment
Referring to Fig.1, the present invention is a kind of intermittent industrial circulating water cultivating method, the reservoir including being connected into circuit
1, aquaculture pond 2, first order reaction pond 3 and second order reaction pond 4；
It is further comprising the steps of:
1) aquaculture pond 2 is drained into first order reaction pond 3, when aquaculture pond 2 is drained into first order reaction pond 3, reservoir 1 to
It supplies water in aquaculture pond 2, maintains constant level in aquaculture pond 2；
2) when aquaculture pond 2 is drained into first order reaction pond 3, first order reaction pond 3 is drained into second order reaction pond 4, when one
Water level reaches setting height in order reaction pond 3 and second order reaction pond 4, and aquaculture pond 2 and first order reaction pond 3 stop draining, level-one
Reaction tank 3 and second order reaction pond 4 are simultaneously handled cultivation water；
3) the cultivation water after treatment in second order reaction pond 4 will be separated between first order reaction pond 3 and second order reaction pond 4,
Cultivation water in second order reaction pond 4 is discharged into reservoir 1 and stores, and first order reaction pond 3 is persistently handled cultivation water to aquaculture pond 2
It drains next time；
4) repeat step 1)~3).
2 bleeding stage of aquaculture pond, electric butterfly valve 5 are powered, and the cultivation water in first order reaction pond 3 flows into second order reaction pond 4；With
Afterwards, the water pump 6 between aquaculture pond 2 and first order reaction pond 3 starts, and the cultivation water of aquaculture pond 2 is pumped into first order reaction pond 3, cultivation
Water also passes through electric butterfly valve 5 and flows into second order reaction pond 4, reaches setting position to liquid level, water pump 6 stops；First order reaction pond 3 and two
Order reaction pond 4 starts aeration progress biochemical reaction, precipitating is separated by solid-liquid separation；After the completion of precipitating, second order reaction pond 4 and water storage
The starting of water pump 6 is drained to reservoir 1 between pond 1；And water while aquaculture pond 2 drains, between reservoir 1 and aquaculture pond 2
Aquaculture pond 2 is added from reservoir 1 in cultivation water by 6 starting of pump, maintains 2 constant level of aquaculture pond.First order reaction pond 3 and second order reaction
Pond 4 is different level, and the biological cleaning to the cultivation water of different quality can be achieved at the same time, and not only purification efficiency is high, and puts into
Cost is relatively low.
As a preferred embodiment of the present invention, it is equipped with elastic filler in first order reaction pond 3 and second order reaction pond 4, about
The 1/3 of biological treatment tank total measurement (volume) is accounted for, for the attachment of each quasi-microorganism.
As a preferred embodiment of the present invention, in step 2), ammonia is launched into first order reaction pond 3 and second order reaction pond 4
Change bacterium, nitrobacteria, denitrifying bacteria.
