Description
Technical field
The present invention relates to a kind of cultivating system of cultural technique field more particularly to it is a kind of based on biological flocculation technology from
Net formula circulating water culture system.
Background technique
Biological flocculation technology by the nitrogen-containing pollutants such as ammonia nitrogen in water body degradation removal or is converted to using microbial action
Bacterium own biological amount is ingested utilizations at particulate matter by aquatic products by bacterium flocculation, with play maintain water environment stabilization,
The effects of reducing quantity of exchanged water, promoting animal immunizing power, improve cultivation survival rate, increasing yield and reduce feed coefficient.
Biological flocculation technology needs to consume a large amount of dissolved oxygen when realizing, such as takes no action to will lead to pond culture aquatic products
Product are because of hypoxia death；It needs to disturb water body simultaneously and forms flow field, so that biological flocculation formation speed is made to balance each other with rate of cleavage,
Achieve the effect that stable.Therefore air is squeezed into water body method using aeration tube in existing biological flocculation cultivation equipment, with
It plays oxygenation and disturbs the function of water body.This water body mode of disturbance up and down is, highly effective in biological flocculation Initial stage of culture.
Increase however as the amount of gathering of biological flocculation, the suspension that the buoyancy being aerated upwards is not enough to support biological flocculation in water body
When state, why biological flocculation can be deposited on bottom of pond.As the biological flocculation amount for accumulating in bottom of pond increases, biological flocculation is by aerobic reaction
It is changed into anaerobic reaction, lead to its corruption and deteriorates water body in turn.At this time by bottom of pond corruption only by way of increase the DO
The biological flocculation discharge cultivating system lost, cultivates biological flocculation again.
Summary of the invention
For problem of the prior art, the present invention provides a kind of auto purification type circulating water cultivation system based on biological flocculation technology
System, the present invention have energy-saving and emission-reduction, high-efficient advantage, solve existing biological flocculation cultivating system needs and refresh the water periodically,
Waste water resource, the high problem of aquaculture cost.
The present invention is implemented with the following technical solutions: a kind of auto purification type circulating water cultivation system based on biological flocculation technology
System, comprising:
More oxygen increasing tubes are arranged in culture zone, bottom；At least one water inlet pipe is arranged in the water inlet end of the culture zone；
Dirt colleceting area is separated by with the discharge ends of the culture zone by a Unidirectional relief structure；In the culture zone
Liquid flows to the dirt colleceting area by the Unidirectional relief structure one-way；And
Mixed zone is used to feed feed to the culture zone, and launches biological carbon source and microorganism inoculant；The collection
The top in dirty area opens up the overflow port that the mixed zone is flowed to for the liquid of the dirt colleceting area, and the height of overflow port is lower than described
The height that liquid flows in Unidirectional relief structure；Mixed zone setting it is corresponding at least one water inlet pipe at least one draw water
Pump；Suction pump extracts the liquid in the mixed zone, and the liquid is transmitted to the culture zone by corresponding water inlet pipe.
