Description
Technical field
The present invention relates to biofiltration device in breeding water body, and in particular to a kind of to be used to cultivate the life in circulation
Thing filter and its water circulation system.
Background technology
Contain substantial amounts of ammonia nitrogen and nitrite in the water of cultivation fish, and fish is containing a large amount of ammonia nitrogens and nitrite ring
It is easily caused anoxic under border and is difficult to survive, therefore, needs often to change cultivation water in cultivation fish, but in many water resources
In the environment of shortage, generation is generally mixed with the ammonia nitrogen and nitrite in cultivation water under aerobic conditions using nitrobacteria
Reaction is converted into nitrate, and fish is higher to the tolerance of nitrate, therefore can realize the function of water circulation use.
Nitrobacteria needs substantial amounts of oxygen in biochemical reaction is carried out, and this is accomplished by carrying out Air Exposure to water.It is described
Aeration is a kind of means for making air and water contact strongly, its object is to which the oxygen in air is dissolved in the water, or by water
Unwanted gas and volatile materials are discharged into air, to realize the means for promoting mass exchange between gas and liquid.
At present, the mode for providing oxygen to nitrobacteria is usually to put into the biologic packing material of nitrobacteria in culturing pool, is then utilized
Oxygen supply is stirred, and the biologic packing material of nitrobacteria, and the biologic packing material for depositing nitrobacteria can not be fully utilized in which
Residue, which is rested in culturing pool, causes secondary pollution water quality, therefore easily cultivation water is had undesirable effect.
And in soilless culture, plant mainly can just be grown by absorbing the nitrate in water, such as at present without soil
Planting vegetable, its cultural method is mainly the pond by specially building planting vegetable, and putting into appropriate nitrate in pond makees
The nutrition supply of culturing vegetable, enables vegetables normally to grow, therefore, and such planting vegetable needs to put into substantial amounts of manpower thing
Power, increases the cost of cultivation.
The content of the invention
The purpose of the present invention is there is above-mentioned technology to solve the biofilter in existing cultivation circulation
There is provided a kind of biofilter and its water circulation system for industrialized aquiculture for problem.
A kind of biofilter for industrialized aquiculture of the object of the invention is realized, includes shell body, inner housing
And filter, the filter and inner housing are arranged in shell body；Described shell body is enclosed on inner casing in vitro, the shell body
Water inner chamber was formed between inner housing, a delivery port is provided with shell body；Described inner housing enters water installations provided with one,
